Ethical Considerations

The APA Code of Ethics guides professionals working in psychology so that they're better equipped with the knowledge of what to do when they encounter some moral or ethical dilemma. Some of these are principles or values that psychologists should aspire to uphold. In other cases, the APA outlines standards that are enforceable expectations.

Ethics are an important concern in psychology, particularly regarding therapy and research. Working with patients and conducting psychological research can pose various ethical and moral issues that must be addressed.

Understanding the APA Code of Ethics

The American Psychological Association (APA) publishes the Ethical Principles of Psychologists and Code of Conduct which outlines aspirational principles as well as enforceable standards that psychologists should use when making decisions.

In 1948, APA president Nicholas Hobbs said, "[The APA Code of Ethics] should be of palpable aid to the ethical psychologist in making daily decisions."

In other words, these ethical codes are meant to guide mental health professionals in making the best ethical decisions on a regular basis.

When Did the APA Publish Its Code of Ethics?

The APA first published its ethics code in 1953 and has been continuously evolving the code ever since.

What's in the APA's Code of Ethics?

The APA code of ethics is composed of key principles and ethical standards:

• Principles : The principles are intended as a guide to help inspire psychologists as they work in their profession, whether they are working in mental health, in research , or in business.
• Standards : The standards outline expectations of conduct. If any of these are violated, it can result in professional and legal ramifications.

Who Is the APA Code of Ethics For?

The code of ethics applies only to work-related, professional activities including research, teaching, counseling , psychotherapy, and consulting. Private conduct is not subject to scrutiny by the APA's ethics committee.

APA's Ethical Codes: The Five Ethical Principles

Not all ethical issues are clear-cut, but the APA strives to offer psychologists guiding principles to help them make sound ethical choices within their profession.

The APA Code of Ethics' Five Principles

• Principle A : Beneficence and Non-Maleficence
• Principle B : Fidelity and Responsibility
• Principle C : Integrity
• Principle D : Justice
• Principle E : Respect for People's Rights and Dignity

Principle A: Beneficence and Non-Maleficence

The first principle of the APA ethics code states that psychologists should strive to protect the rights and welfare of those with whom they work professionally . This includes the clients they see in clinical practice, animals that are involved in research and experiments , and anyone else with whom they engage in professional interaction.

This principle encourages psychologists to strive to eliminate biases , affiliations, and prejudices that might influence their work. This includes acting independently in research and not allowing affiliations or sponsorships to influence results.

Principle B: Fidelity and Responsibility

Principle B states that psychologists have a moral responsibility to help ensure that others working in their profession also uphold high ethical standards . This principle suggests that psychologists should participate in activities that enhance the ethical compliance and conduct of their colleagues.

Serving as a mentor, taking part in peer review, and pointing out ethical concerns or misconduct are examples of how this principle might be put into action. Psychologists are also encouraged to donate some of their time to the betterment of the community.

Principle C: Integrity

This principle states that, in research and practice, psychologists should never attempt to deceive or misrepresent . For instance, in research, deception can involve fabricating or manipulating results in some way to achieve desired outcomes. Psychologists should also strive for transparency and honesty in their practice.

Principle D: Justice

The principle of justice says that mental health professionals have a responsibility to be fair and impartial. It also states that people have a right to access and benefit from advances that have been made in the field of psychology. It is important for psychologists to treat people equally.

Psychologists should also always practice within their area of expertise and also be aware of their level of competence and limitations.

Principle E: Respect for People's Rights and Dignity

Principle E states that psychologists should respect the right to dignity, privacy, and confidentiality of those they work with professionally . They should also strive to minimize their own biases as well as be aware of issues related to diversity and the concerns of particular populations.

For example, people may have specific concerns related to their age, socioeconomic status, race , gender, religion, ethnicity, or disability.

The APA Code of Ethics' Standards

The 10 standards found in the APA ethics code are enforceable rules of conduct for psychologists working in clinical practice and academia.

The 10 Standards Found in the APA Code of Ethics

• Resolving Ethical Issues
• Human Relations
• Privacy and Confidentiality
• Advertising and Other Public Statements
• Record Keeping and Fees
• Education and Training
• Research and Publication

These standards tend to be broad in order to help guide the behavior of psychologists across a wide variety of domains and situations.

They apply to areas such as education, therapy, advertising, privacy, research, and publication.

1: Resolving Ethical Issues

This standard of the APA ethics code provides information about what psychologists should do to resolve ethical situations they may encounter in their work. This includes advice for what researchers should do when their work is misrepresented and when to report ethical violations.

2: Competence

It is important that psychologists practice within their area of expertise. When treating clients or working with the public, psychologists must make it clear what they are trained to do as well as what they are not trained to do.

An Exception to This Standard

This standard stipulates that in an emergency situation, professionals may provide services even if it falls outside the scope of their practice in order to ensure that access to services is provided.

3: Human Relations

Psychologists frequently work with a team of other mental health professionals. This standard of the ethics code is designed to guide psychologists in their interactions with others in the field.

This includes guidelines for dealing with sexual harassment, and discrimination, avoiding harm during treatment and avoiding exploitative relationships (such as a sexual relationship with a student or subordinate).

4: Privacy and Confidentiality

This standard outlines psychologists’ responsibilities with regard to maintaining patient confidentiality . Psychologists are obligated to take reasonable precautions to keep client information private.

However, the APA also notes that there are limitations to confidentiality. Sometimes psychologists need to disclose information about their patients in order to consult with other mental health professionals, for example.

While there are cases where information is divulged, psychologists must strive to minimize these intrusions on privacy and confidentiality.

5: Advertising and Other Public Statements

Psychologists who advertise their services must ensure that they accurately depict their training, experience, and expertise. They also need to avoid marketing statements that are deceptive or false.

This also applies to how psychologists are portrayed by the media when providing their expertise or opinion in articles, blogs, books, or television programs.

When presenting at conferences or giving workshops, psychologists should also ensure that the brochures and other marketing materials for the event accurately depict what the event will cover.

6: Record Keeping and Fees

Maintaining accurate records is an important part of a psychologist’s work, whether the individual is working in research or with patients. Patient records include case notes and other diagnostic assessments used in the course of treatment.

In terms of research, record-keeping involves detailing how studies were performed and the procedures that were used. This allows other researchers to assess the research and ensures that the study can be replicated.

7: Education and Training

This standard focuses on expectations for behavior when psychologists are teaching or training students.

When creating courses and programs to train other psychologists and mental health professionals , current and accurate evidence-based research should be used.

This standard also states that faculty members are not allowed to provide psychotherapy services to their students.

8: Research and Publication

This standard focuses on ethical considerations when conducting research and publishing results .

For example, the APA states that psychologists must obtain approval from the institution that is carrying out the research, present information about the purpose of the study to participants, and inform participants about the potential risks of taking part in the research.

9: Assessment

Psychologists should obtain informed consent before administering assessments. Assessments should be used to support a psychologist’s professional opinion, but psychologists should also understand the limitations of these tools. They should also take steps to ensure the privacy of those who have taken assessments.

10: Therapy

This standard outlines professional expectations within the context of providing therapy. Areas that are addressed include the importance of obtaining informed consent and explaining the treatment process to clients.

Confidentiality is addressed, as well as some of the limitations to confidentiality, such as when a client poses an immediate danger to himself or others.

Minimizing harm, avoiding sexual relationships with clients, and continuation of care are other areas that are addressed by this standard.

For example, if a psychologist must stop providing services to a client for some reason, psychologists are expected to prepare clients for the change and help locate alternative services.

What Happens If a Therapist Violates the APA's Ethical Codes?

After a report of unethical conduct is received, the APA may censure or reprimand the psychologist, or the individual may have his or her APA membership revoked. Complaints may also be referred to others, including state professional licensing boards.

State psychological associations, professional groups, licensing boards, and government agencies may also choose to impose penalties against the psychologist.

Health insurance agencies and state and federal payers of health insurance claims may also pursue action against professionals for ethical violations related to treatment, billing, or fraud.

Those affected by ethical violations may also opt to seek monetary damages in civil courts.

Illegal activity may be prosecuted in criminal courts. If this results in a felony conviction, the APA may take further actions including suspension or expulsion from state psychological associations and the suspension or loss of the psychologist's license to practice.

How Can I Report a Therapist for Unethical Behavior?

While unfortunate, there are instances in which a therapist may commit an ethical violation. If you would like to file a complaint against a therapist, you can do so by contacting your state's psychologist licensing board.

How to Find Your State's Psychologist Board

Here is a list of the U.S. psychology boards . Choose your state and refer to the contact information provided.

Because psychologists often deal with extremely sensitive or volatile situations, ethical concerns can play a big role in professional life.

The most significant ethical issues include the following:

• Client Welfare : Due to the role they serve, psychologists often work with individuals who are vulnerable due to their age, disability, intellectual ability, and other concerns. When working with these individuals, psychologists must always strive to protect the welfare of their clients.
• Informed Consent : Psychologists are responsible for providing a wide range of services in their roles as therapists, researchers, educators, and consultants. When people are acting as consumers of psychological services, they have a right to know what to expect. In therapy, obtaining informed consent involves explaining what services are offered, what the possible risks might be, and the patient’s right to leave treatment. When conducting research, informed consent involves letting participants know about any possible risks of taking part in the research.
• Confidentiality : Therapy requires providing a safe place for clients to discuss highly personal issues without fear of having this information shared with others or made public. However, sometimes a psychologist might need to share some details such as when consulting with other professionals or when they are publishing research. Ethical guidelines dictate when and how some information might be shared, as well as some of the steps that psychologists should take to protect client privacy.
• Competence : The training, education, and experience of psychologists is also an important ethical concern. Psychologists must possess the skill and knowledge to properly provide the services that clients need. For example, if a psychologist needs to administer a particular assessment in the course of treatment, they should have an understanding of both the administration and interpretation of that specific test.

While ethical codes exist to help psychologists, this does not mean that psychology is free of ethical controversy today. Current debates over psychologists’ participation in torture and the use of animals in psychological research remain hot-button ethical concerns.

Conducting and presenting research ethically is an important aspect of the research process because it protects the individuals involved and promotes accuracy in reporting, which leads to knowledge, advancement, and trust. Some journals require that research proposals, especially those with human and animal subjects, receive approval from an institutional review board (IRB) at the institution where the research will be conducted PRIOR to beginning the research. In addition, many journals require written confirmation of compliance with ethical principles to be included during the submission process. 

Many professional organizations have established ethical codes or guidelines for their members:

• APA Ethical Principles of Psychologists and Code of Conduct More commonly known as the APA Ethics Code, it provides guidelines for psychiatrists and psychologists when working in their field and participating in research.
• AMA Code of Medical Ethics The American Medical Association has maintained a code of ethics since its founding in 1847.
• NASW Code of Ethics The National Association of Social Workers provides guidelines for social workers.
• National Association of Realtors The National Association of Realtors provides a Code of Ethics and Standards of Practice for realtors.
• ASA Code of Ethics The American Sociological Association provides a code of ethics for professional sociologists.
• ACM Code of Ethics and Professional Conduct The Association for Computing Machinery provides a code of ethics and professional conduct for computing professionals.
• There are many more Search for ethics within your primary organization(s) to see if they provide any guidelines.

8.01 Institutional Approval

When institutional approval is required, psychologists provide accurate information about their research proposals and obtain approval prior to conducting the research. They conduct the research in accordance with the approved research protocol.

8.02 Informed Consent to Research

• When obtaining informed consent as required in Standard 3.10, Informed Consent, psychologists inform participants about (1) the purpose of the research, expected duration, and procedures; (2) their right to decline to participate and to withdraw from the research once participation has begun; (3) the foreseeable consequences of declining or withdrawing; (4) reasonably foreseeable factors that may be expected to influence their willingness to participate such as potential risks, discomfort, or adverse effects; (5) any prospective research benefits; (6) limits of confidentiality; (7) incentives for participation; and (8) whom to contact for questions about the research and research participants’ rights. They provide opportunity for the prospective participants to ask questions and receive answers. (See also Standards 8.03, Informed Consent for Recording Voices and Images in Research; 8.05, Dispensing With Informed Consent for Research; and 8.07, Deception in Research.)
• Psychologists conducting intervention research involving the use of experimental treatments clarify to participants at the outset of the research (1) the experimental nature of the treatment; (2) the services that will or will not be available to the control group(s) if appropriate; (3) the means by which assignment to treatment and control groups will be made; (4) available treatment alternatives if an individual does not wish to participate in the research or wishes to withdraw once a study has begun; and (5) compensation for or monetary costs of participating including, if appropriate, whether reimbursement from the participant or a third-party payor will be sought. (See also Standard 8.02a, Informed Consent to Research.)

8.03 Informed Consent for Recording Voices and Images in Research

Psychologists obtain informed consent from research participants prior to recording their voices or images for data collection unless (1) the research consists solely of naturalistic observations in public places, and it is not anticipated that the recording will be used in a manner that could cause personal identification or harm, or (2) the research design includes deception, and consent for the use of the recording is obtained during debriefing. (See also Standard 8.07, Deception in Research.)

8.04 Client/Patient, Student, and Subordinate Research Participants

• When psychologists conduct research with clients/patients, students, or subordinates as participants, psychologists take steps to protect the prospective participants from adverse consequences of declining or withdrawing from participation.
• When research participation is a course requirement or an opportunity for extra credit, the prospective participant is given the choice of equitable alternative activities.

8.05 Dispensing With Informed Consent for Research

Psychologists may dispense with informed consent only (1) where research would not reasonably be assumed to create distress or harm and involves (a) the study of normal educational practices, curricula, or classroom management methods conducted in educational settings; (b) only anonymous questionnaires, naturalistic observations, or archival research for which disclosure of responses would not place participants at risk of criminal or civil liability or damage their financial standing, employability, or reputation, and confidentiality is protected; or (c) the study of factors related to job or organization effectiveness conducted in organizational settings for which there is no risk to participants’ employability, and confidentiality is protected or (2) where otherwise permitted by law or federal or institutional regulations.

8.06 Offering Inducements for Research Participation

• Psychologists make reasonable efforts to avoid offering excessive or inappropriate financial or other inducements for research participation when such inducements are likely to coerce participation.
• When offering professional services as an inducement for research participation, psychologists clarify the nature of the services, as well as the risks, obligations, and limitations. (See also Standard 6.05, Barter With Clients/Patients.)

8.07 Deception in Research

• Psychologists do not conduct a study involving deception unless they have determined that the use of deceptive techniques is justified by the study’s significant prospective scientific, educational, or applied value and that effective nondeceptive alternative procedures are not feasible.
• Psychologists do not deceive prospective participants about research that is reasonably expected to cause physical pain or severe emotional distress.
• Psychologists explain any deception that is an integral feature of the design and conduct of an experiment to participants as early as is feasible, preferably at the conclusion of their participation, but no later than at the conclusion of the data collection, and permit participants to withdraw their data. (See also Standard 8.08, Debriefing.)

8.08 Debriefing

• Psychologists provide a prompt opportunity for participants to obtain appropriate information about the nature, results, and conclusions of the research, and they take reasonable steps to correct any misconceptions that participants may have of which the psychologists are aware.
• If scientific or humane values justify delaying or withholding this information, psychologists take reasonable measures to reduce the risk of harm.
• When psychologists become aware that research procedures have harmed a participant, they take reasonable steps to minimize the harm.

8.09 Humane Care and Use of Animals in Research

• Psychologists acquire, care for, use, and dispose of animals in compliance with current federal, state, and local laws and regulations, and with professional standards.
• Psychologists trained in research methods and experienced in the care of laboratory animals supervise all procedures involving animals and are responsible for ensuring appropriate consideration of their comfort, health, and humane treatment.
• Psychologists ensure that all individuals under their supervision who are using animals have received instruction in research methods and in the care, maintenance, and handling of the species being used, to the extent appropriate to their role. (See also Standard 2.05, Delegation of Work to Others.)
• Psychologists make reasonable efforts to minimize the discomfort, infection, illness, and pain of animal subjects.
• Psychologists use a procedure subjecting animals to pain, stress, or privation only when an alternative procedure is unavailable and the goal is justified by its prospective scientific, educational, or applied value.
• Psychologists perform surgical procedures under appropriate anesthesia and follow techniques to avoid infection and minimize pain during and after surgery.
• When it is appropriate that an animal’s life be terminated, psychologists proceed rapidly, with an effort to minimize pain and in accordance with accepted procedures.

8.10 Reporting Research Results

• Psychologists do not fabricate data. (See also Standard 5.01a, Avoidance of False or Deceptive Statements.)
• If psychologists discover significant errors in their published data, they take reasonable steps to correct such errors in a correction, retraction, erratum, or other appropriate publication means.

8.11 Plagiarism

Psychologists do not present portions of another’s work or data as their own, even if the other work or data source is cited occasionally.

8.12 Publication Credit

• Psychologists take responsibility and credit, including authorship credit, only for work they have actually performed or to which they have substantially contributed. (See also Standard 8.12b, Publication Credit.)
• Principal authorship and other publication credits accurately reflect the relative scientific or professional contributions of the individuals involved, regardless of their relative status. Mere possession of an institutional position, such as department chair, does not justify authorship credit. Minor contributions to the research or to the writing for publications are acknowledged appropriately, such as in footnotes or in an introductory statement.
• Except under exceptional circumstances, a student is listed as principal author on any multiple-authored article that is substantially based on the student’s doctoral dissertation. Faculty advisors discuss publication credit with students as early as feasible and throughout the research and publication process as appropriate. (See also Standard 8.12b, Publication Credit.)

8.13 Duplicate Publication of Data

Psychologists do not publish, as original data, data that have been previously published. This does not preclude republishing data when they are accompanied by proper acknowledgment.

8.14 Sharing Research Data for Verification

• After research results are published, psychologists do not withhold the data on which their conclusions are based from other competent professionals who seek to verify the substantive claims through reanalysis and who intend to use such data only for that purpose, provided that the confidentiality of the participants can be protected and unless legal rights concerning proprietary data preclude their release. This does not preclude psychologists from requiring that such individuals or groups be responsible for costs associated with the provision of such information.
• Psychologists who request data from other psychologists to verify the substantive claims through reanalysis may use shared data only for the declared purpose. Requesting psychologists obtain prior written agreement for all other uses of the data.

8.15 Reviewers

Psychologists who review material submitted for presentation, publication, grant, or research proposal review respect the confidentiality of and the proprietary rights in such information of those who submitted it.

Ethical Considerations in Research | Types & Examples

Published on October 18, 2021 by Pritha Bhandari . Revised on June 22, 2023.

Ethical considerations in research are a set of principles that guide your research designs and practices. Scientists and researchers must always adhere to a certain code of conduct when collecting data from people.

The goals of human research often include understanding real-life phenomena, studying effective treatments, investigating behaviors, and improving lives in other ways. What you decide to research and how you conduct that research involve key ethical considerations.

These considerations work to

• protect the rights of research participants
• enhance research validity
• maintain scientific or academic integrity

Research ethics matter for scientific integrity, human rights and dignity, and collaboration between science and society. These principles make sure that participation in studies is voluntary, informed, and safe for research subjects.

You’ll balance pursuing important research objectives with using ethical research methods and procedures. It’s always necessary to prevent permanent or excessive harm to participants, whether inadvertent or not.

Defying research ethics will also lower the credibility of your research because it’s hard for others to trust your data if your methods are morally questionable.

Even if a research idea is valuable to society, it doesn’t justify violating the human rights or dignity of your study participants.

Receive feedback on language, structure, and formatting

Professional editors proofread and edit your paper by focusing on:

• Academic style
• Vague sentences
• Style consistency

See an example

Before you start any study involving data collection with people, you’ll submit your research proposal to an institutional review board (IRB) .

An IRB is a committee that checks whether your research aims and research design are ethically acceptable and follow your institution’s code of conduct. They check that your research materials and procedures are up to code.

If successful, you’ll receive IRB approval, and you can begin collecting data according to the approved procedures. If you want to make any changes to your procedures or materials, you’ll need to submit a modification application to the IRB for approval.

If unsuccessful, you may be asked to re-submit with modifications or your research proposal may receive a rejection. To get IRB approval, it’s important to explicitly note how you’ll tackle each of the ethical issues that may arise in your study.

There are several ethical issues you should always pay attention to in your research design, and these issues can overlap with each other.

You’ll usually outline ways you’ll deal with each issue in your research proposal if you plan to collect data from participants.

Voluntary participation means that all research subjects are free to choose to participate without any pressure or coercion.

All participants are able to withdraw from, or leave, the study at any point without feeling an obligation to continue. Your participants don’t need to provide a reason for leaving the study.

It’s important to make it clear to participants that there are no negative consequences or repercussions to their refusal to participate. After all, they’re taking the time to help you in the research process , so you should respect their decisions without trying to change their minds.

Voluntary participation is an ethical principle protected by international law and many scientific codes of conduct.

Take special care to ensure there’s no pressure on participants when you’re working with vulnerable groups of people who may find it hard to stop the study even when they want to.

Prevent plagiarism. Run a free check.

Informed consent refers to a situation in which all potential participants receive and understand all the information they need to decide whether they want to participate. This includes information about the study’s benefits, risks, funding, and institutional approval.

You make sure to provide all potential participants with all the relevant information about

• what the study is about
• the risks and benefits of taking part
• how long the study will take
• your supervisor’s contact information and the institution’s approval number

Usually, you’ll provide participants with a text for them to read and ask them if they have any questions. If they agree to participate, they can sign or initial the consent form. Note that this may not be sufficient for informed consent when you work with particularly vulnerable groups of people.

If you’re collecting data from people with low literacy, make sure to verbally explain the consent form to them before they agree to participate.

For participants with very limited English proficiency, you should always translate the study materials or work with an interpreter so they have all the information in their first language.

In research with children, you’ll often need informed permission for their participation from their parents or guardians. Although children cannot give informed consent, it’s best to also ask for their assent (agreement) to participate, depending on their age and maturity level.

Anonymity means that you don’t know who the participants are and you can’t link any individual participant to their data.

You can only guarantee anonymity by not collecting any personally identifying information—for example, names, phone numbers, email addresses, IP addresses, physical characteristics, photos, and videos.

In many cases, it may be impossible to truly anonymize data collection . For example, data collected in person or by phone cannot be considered fully anonymous because some personal identifiers (demographic information or phone numbers) are impossible to hide.

You’ll also need to collect some identifying information if you give your participants the option to withdraw their data at a later stage.

Data pseudonymization is an alternative method where you replace identifying information about participants with pseudonymous, or fake, identifiers. The data can still be linked to participants but it’s harder to do so because you separate personal information from the study data.

Confidentiality means that you know who the participants are, but you remove all identifying information from your report.

All participants have a right to privacy, so you should protect their personal data for as long as you store or use it. Even when you can’t collect data anonymously, you should secure confidentiality whenever you can.

Some research designs aren’t conducive to confidentiality, but it’s important to make all attempts and inform participants of the risks involved.

As a researcher, you have to consider all possible sources of harm to participants. Harm can come in many different forms.

• Psychological harm: Sensitive questions or tasks may trigger negative emotions such as shame or anxiety.
• Social harm: Participation can involve social risks, public embarrassment, or stigma.
• Physical harm: Pain or injury can result from the study procedures.
• Legal harm: Reporting sensitive data could lead to legal risks or a breach of privacy.

It’s best to consider every possible source of harm in your study as well as concrete ways to mitigate them. Involve your supervisor to discuss steps for harm reduction.

Make sure to disclose all possible risks of harm to participants before the study to get informed consent. If there is a risk of harm, prepare to provide participants with resources or counseling or medical services if needed.

Some of these questions may bring up negative emotions, so you inform participants about the sensitive nature of the survey and assure them that their responses will be confidential.

The way you communicate your research results can sometimes involve ethical issues. Good science communication is honest, reliable, and credible. It’s best to make your results as transparent as possible.

Take steps to actively avoid plagiarism and research misconduct wherever possible.

Plagiarism means submitting others’ works as your own. Although it can be unintentional, copying someone else’s work without proper credit amounts to stealing. It’s an ethical problem in research communication because you may benefit by harming other researchers.

Self-plagiarism is when you republish or re-submit parts of your own papers or reports without properly citing your original work.

This is problematic because you may benefit from presenting your ideas as new and original even though they’ve already been published elsewhere in the past. You may also be infringing on your previous publisher’s copyright, violating an ethical code, or wasting time and resources by doing so.

In extreme cases of self-plagiarism, entire datasets or papers are sometimes duplicated. These are major ethical violations because they can skew research findings if taken as original data.

You notice that two published studies have similar characteristics even though they are from different years. Their sample sizes, locations, treatments, and results are highly similar, and the studies share one author in common.

Research misconduct

Research misconduct means making up or falsifying data, manipulating data analyses, or misrepresenting results in research reports. It’s a form of academic fraud.

These actions are committed intentionally and can have serious consequences; research misconduct is not a simple mistake or a point of disagreement about data analyses.

Research misconduct is a serious ethical issue because it can undermine academic integrity and institutional credibility. It leads to a waste of funding and resources that could have been used for alternative research.

Later investigations revealed that they fabricated and manipulated their data to show a nonexistent link between vaccines and autism. Wakefield also neglected to disclose important conflicts of interest, and his medical license was taken away.

This fraudulent work sparked vaccine hesitancy among parents and caregivers. The rate of MMR vaccinations in children fell sharply, and measles outbreaks became more common due to a lack of herd immunity.

Research scandals with ethical failures are littered throughout history, but some took place not that long ago.

Some scientists in positions of power have historically mistreated or even abused research participants to investigate research problems at any cost. These participants were prisoners, under their care, or otherwise trusted them to treat them with dignity.

To demonstrate the importance of research ethics, we’ll briefly review two research studies that violated human rights in modern history.

These experiments were inhumane and resulted in trauma, permanent disabilities, or death in many cases.

After some Nazi doctors were put on trial for their crimes, the Nuremberg Code of research ethics for human experimentation was developed in 1947 to establish a new standard for human experimentation in medical research.

In reality, the actual goal was to study the effects of the disease when left untreated, and the researchers never informed participants about their diagnoses or the research aims.

Although participants experienced severe health problems, including blindness and other complications, the researchers only pretended to provide medical care.

When treatment became possible in 1943, 11 years after the study began, none of the participants were offered it, despite their health conditions and high risk of death.

Ethical failures like these resulted in severe harm to participants, wasted resources, and lower trust in science and scientists. This is why all research institutions have strict ethical guidelines for performing research.

Ethical considerations in research are a set of principles that guide your research designs and practices. These principles include voluntary participation, informed consent, anonymity, confidentiality, potential for harm, and results communication.

Scientists and researchers must always adhere to a certain code of conduct when collecting data from others .

These considerations protect the rights of research participants, enhance research validity , and maintain scientific integrity.

Research ethics matter for scientific integrity, human rights and dignity, and collaboration between science and society. These principles make sure that participation in studies is voluntary, informed, and safe.

Anonymity means you don’t know who the participants are, while confidentiality means you know who they are but remove identifying information from your research report. Both are important ethical considerations .

You can only guarantee anonymity by not collecting any personally identifying information—for example, names, phone numbers, email addresses, IP addresses, physical characteristics, photos, or videos.

You can keep data confidential by using aggregate information in your research report, so that you only refer to groups of participants rather than individuals.

These actions are committed intentionally and can have serious consequences; research misconduct is not a simple mistake or a point of disagreement but a serious ethical failure.

Ethics refers to the correct rules of conduct necessary when carrying out research. We have a moral responsibility to protect research participants from harm.

However important the issue under investigation, psychologists must remember that they have a duty to respect the rights and dignity of research participants. This means that they must abide by certain moral principles and rules of conduct.

What are Ethical Guidelines?

In Britain, ethical guidelines for research are published by the British Psychological Society, and in America, by the American Psychological Association. The purpose of these codes of conduct is to protect research participants, the reputation of psychology, and psychologists themselves.

Moral issues rarely yield a simple, unambiguous, right or wrong answer. It is, therefore, often a matter of judgment whether the research is justified or not.

For example, it might be that a study causes psychological or physical discomfort to participants; maybe they suffer pain or perhaps even come to serious harm.

On the other hand, the investigation could lead to discoveries that benefit the participants themselves or even have the potential to increase the sum of human happiness.

Rosenthal and Rosnow (1984) also discuss the potential costs of failing to carry out certain research. Who is to weigh up these costs and benefits? Who is to judge whether the ends justify the means?

Finally, if you are ever in doubt as to whether research is ethical or not, it is worthwhile remembering that if there is a conflict of interest between the participants and the researcher, it is the interests of the subjects that should take priority.

Studies must now undergo an extensive review by an institutional review board (US) or ethics committee (UK) before they are implemented. All UK research requires ethical approval by one or more of the following:

• Department Ethics Committee (DEC) : for most routine research.
• Institutional Ethics Committee (IEC) : for non-routine research.
• External Ethics Committee (EEC) : for research that s externally regulated (e.g., NHS research).

Committees review proposals to assess if the potential benefits of the research are justifiable in light of the possible risk of physical or psychological harm.

These committees may request researchers make changes to the study’s design or procedure or, in extreme cases, deny approval of the study altogether.

The British Psychological Society (BPS) and American Psychological Association (APA) have issued a code of ethics in psychology that provides guidelines for conducting research.  Some of the more important ethical issues are as follows:

Informed Consent

Before the study begins, the researcher must outline to the participants what the research is about and then ask for their consent (i.e., permission) to participate.

An adult (18 years +) capable of being permitted to participate in a study can provide consent. Parents/legal guardians of minors can also provide consent to allow their children to participate in a study.

Whenever possible, investigators should obtain the consent of participants. In practice, this means it is not sufficient to get potential participants to say “Yes.”

They also need to know what it is that they agree to. In other words, the psychologist should, so far as is practicable, explain what is involved in advance and obtain the informed consent of participants.

Informed consent must be informed, voluntary, and rational. Participants must be given relevant details to make an informed decision, including the purpose, procedures, risks, and benefits. Consent must be given voluntarily without undue coercion. And participants must have the capacity to rationally weigh the decision.

Components of informed consent include clearly explaining the risks and expected benefits, addressing potential therapeutic misconceptions about experimental treatments, allowing participants to ask questions, and describing methods to minimize risks like emotional distress.

Investigators should tailor the consent language and process appropriately for the study population. Obtaining meaningful informed consent is an ethical imperative for human subjects research.

The voluntary nature of participation should not be compromised through coercion or undue influence. Inducements should be fair and not excessive/inappropriate.

However, it is not always possible to gain informed consent.  Where the researcher can’t ask the actual participants, a similar group of people can be asked how they would feel about participating.

If they think it would be OK, then it can be assumed that the real participants will also find it acceptable. This is known as presumptive consent.

However, a problem with this method is that there might be a mismatch between how people think they would feel/behave and how they actually feel and behave during a study.

In order for consent to be ‘informed,’ consent forms may need to be accompanied by an information sheet for participants’ setting out information about the proposed study (in lay terms), along with details about the investigators and how they can be contacted.

Special considerations exist when obtaining consent from vulnerable populations with decisional impairments, such as psychiatric patients, intellectually disabled persons, and children/adolescents. Capacity can vary widely so should be assessed individually, but interventions to improve comprehension may help. Legally authorized representatives usually must provide consent for children.

Participants must be given information relating to the following:

• A statement that participation is voluntary and that refusal to participate will not result in any consequences or any loss of benefits that the person is otherwise entitled to receive.
• Purpose of the research.
• All foreseeable risks and discomforts to the participant (if there are any). These include not only physical injury but also possible psychological.
• Procedures involved in the research.
• Benefits of the research to society and possibly to the individual human subject.
• Length of time the subject is expected to participate.
• Person to contact for answers to questions or in the event of injury or emergency.
• Subjects” right to confidentiality and the right to withdraw from the study at any time without any consequences.

Debriefing after a study involves informing participants about the purpose, providing an opportunity to ask questions, and addressing any harm from participation. Debriefing serves an educational function and allows researchers to correct misconceptions. It is an ethical imperative.

After the research is over, the participant should be able to discuss the procedure and the findings with the psychologist. They must be given a general idea of what the researcher was investigating and why, and their part in the research should be explained.

Participants must be told if they have been deceived and given reasons why. They must be asked if they have any questions, which should be answered honestly and as fully as possible.

Debriefing should occur as soon as possible and be as full as possible; experimenters should take reasonable steps to ensure that participants understand debriefing.

“The purpose of debriefing is to remove any misconceptions and anxieties that the participants have about the research and to leave them with a sense of dignity, knowledge, and a perception of time not wasted” (Harris, 1998).

The debriefing aims to provide information and help the participant leave the experimental situation in a similar frame of mind as when he/she entered it (Aronson, 1988).

Exceptions may exist if debriefing seriously compromises study validity or causes harm itself, like negative emotions in children. Consultation with an institutional review board guides exceptions.

Debriefing indicates investigators’ commitment to participant welfare. Harms may not be raised in the debriefing itself, so responsibility continues after data collection. Following up demonstrates respect and protects persons in human subjects research.

Protection of Participants

Researchers must ensure that those participating in research will not be caused distress. They must be protected from physical and mental harm. This means you must not embarrass, frighten, offend or harm participants.

Normally, the risk of harm must be no greater than in ordinary life, i.e., participants should not be exposed to risks greater than or additional to those encountered in their normal lifestyles.

The researcher must also ensure that if vulnerable groups are to be used (elderly, disabled, children, etc.), they must receive special care. For example, if studying children, ensure their participation is brief as they get tired easily and have a limited attention span.

Researchers are not always accurately able to predict the risks of taking part in a study, and in some cases, a therapeutic debriefing may be necessary if participants have become disturbed during the research (as happened to some participants in Zimbardo’s prisoners/guards study ).

Deception research involves purposely misleading participants or withholding information that could influence their participation decision. This method is controversial because it limits informed consent and autonomy, but can provide otherwise unobtainable valuable knowledge.

Types of deception include (i) deliberate misleading, e.g. using confederates, staged manipulations in field settings, deceptive instructions; (ii) deception by omission, e.g., failure to disclose full information about the study, or creating ambiguity.

The researcher should avoid deceiving participants about the nature of the research unless there is no alternative – and even then, this would need to be judged acceptable by an independent expert. However, some types of research cannot be carried out without at least some element of deception.

For example, in Milgram’s study of obedience , the participants thought they were giving electric shocks to a learner when they answered a question wrongly. In reality, no shocks were given, and the learners were confederates of Milgram.

This is sometimes necessary to avoid demand characteristics (i.e., the clues in an experiment that lead participants to think they know what the researcher is looking for).

Another common example is when a stooge or confederate of the experimenter is used (this was the case in both the experiments carried out by Asch ).

According to ethics codes, deception must have strong scientific justification, and non-deceptive alternatives should not be feasible. Deception that causes significant harm is prohibited. Investigators should carefully weigh whether deception is necessary and ethical for their research.

However, participants must be deceived as little as possible, and any deception must not cause distress.  Researchers can determine whether participants are likely distressed when deception is disclosed by consulting culturally relevant groups.

Participants should immediately be informed of the deception without compromising the study’s integrity. Reactions to learning of deception can range from understanding to anger. Debriefing should explain the scientific rationale and social benefits to minimize negative reactions.

If the participant is likely to object or be distressed once they discover the true nature of the research at debriefing, then the study is unacceptable.

If you have gained participants’ informed consent by deception, then they will have agreed to take part without actually knowing what they were consenting to.  The true nature of the research should be revealed at the earliest possible opportunity or at least during debriefing.

Some researchers argue that deception can never be justified and object to this practice as it (i) violates an individual’s right to choose to participate; (ii) is a questionable basis on which to build a discipline; and (iii) leads to distrust of psychology in the community.

Confidentiality

Protecting participant confidentiality is an ethical imperative that demonstrates respect, ensures honest participation, and prevents harms like embarrassment or legal issues. Methods like data encryption, coding systems, and secure storage should match the research methodology.

Participants and the data gained from them must be kept anonymous unless they give their full consent.  No names must be used in a lab report .

Researchers must clearly describe to participants the limits of confidentiality and methods to protect privacy. With internet research, threats exist like third-party data access; security measures like encryption should be explained. For non-internet research, other protections should be noted too, like coding systems and restricted data access.

High-profile data breaches have eroded public trust. Methods that minimize identifiable information can further guard confidentiality. For example, researchers can consider whether birthdates are necessary or just ages.

Generally, reducing personal details collected and limiting accessibility safeguards participants. Following strong confidentiality protections demonstrates respect for persons in human subjects research.

What do we do if we discover something that should be disclosed (e.g., a criminal act)? Researchers have no legal obligation to disclose criminal acts and must determine the most important consideration: their duty to the participant vs. their duty to the wider community.

Ultimately, decisions to disclose information must be set in the context of the research aims.

Withdrawal from an Investigation

Participants should be able to leave a study anytime if they feel uncomfortable. They should also be allowed to withdraw their data. They should be told at the start of the study that they have the right to withdraw.

They should not have pressure placed upon them to continue if they do not want to (a guideline flouted in Milgram’s research).

Participants may feel they shouldn’t withdraw as this may ‘spoil’ the study. Many participants are paid or receive course credits; they may worry they won’t get this if they withdraw.

Even at the end of the study, the participant has a final opportunity to withdraw the data they have provided for the research.

Ethical Issues in Psychology & Socially Sensitive Research

There has been an assumption over the years by many psychologists that provided they follow the BPS or APA guidelines when using human participants and that all leave in a similar state of mind to how they turned up, not having been deceived or humiliated, given a debrief, and not having had their confidentiality breached, that there are no ethical concerns with their research.

But consider the following examples:

a) Caughy et al. 1994 found that middle-class children in daycare at an early age generally score less on cognitive tests than children from similar families reared in the home.

Assuming all guidelines were followed, neither the parents nor the children participating would have been unduly affected by this research. Nobody would have been deceived, consent would have been obtained, and no harm would have been caused.

However, consider the wider implications of this study when the results are published, particularly for parents of middle-class infants who are considering placing their young children in daycare or those who recently have!

b)  IQ tests administered to black Americans show that they typically score 15 points below the average white score.

When black Americans are given these tests, they presumably complete them willingly and are not harmed as individuals. However, when published, findings of this sort seek to reinforce racial stereotypes and are used to discriminate against the black population in the job market, etc.

Sieber & Stanley (1988) (the main names for Socially Sensitive Research (SSR) outline 4 groups that may be affected by psychological research: It is the first group of people that we are most concerned with!

• Members of the social group being studied, such as racial or ethnic group. For example, early research on IQ was used to discriminate against US Blacks.
• Friends and relatives of those participating in the study, particularly in case studies, where individuals may become famous or infamous. Cases that spring to mind would include Genie’s mother.
• The research team. There are examples of researchers being intimidated because of the line of research they are in.
• The institution in which the research is conducted.

salso suggest there are 4 main ethical concerns when conducting SSR:

• The research question or hypothesis.
• The treatment of individual participants.
• The institutional context.
• How the findings of the research are interpreted and applied.

Ethical Guidelines For Carrying Out SSR

Sieber and Stanley suggest the following ethical guidelines for carrying out SSR. There is some overlap between these and research on human participants in general.

Privacy : This refers to people rather than data. Asking people questions of a personal nature (e.g., about sexuality) could offend.

Confidentiality: This refers to data. Information (e.g., about H.I.V. status) leaked to others may affect the participant’s life.

Sound & valid methodology : This is even more vital when the research topic is socially sensitive. Academics can detect flaws in methods, but the lay public and the media often don’t.

When research findings are publicized, people are likely to consider them fact, and policies may be based on them. Examples are Bowlby’s maternal deprivation studies and intelligence testing.

Deception : Causing the wider public to believe something, which isn’t true by the findings, you report (e.g., that parents are responsible for how their children turn out).

Informed consent : Participants should be made aware of how participating in the research may affect them.

Justice & equitable treatment : Examples of unjust treatment are (i) publicizing an idea, which creates a prejudice against a group, & (ii) withholding a treatment, which you believe is beneficial, from some participants so that you can use them as controls.

Scientific freedom : Science should not be censored, but there should be some monitoring of sensitive research. The researcher should weigh their responsibilities against their rights to do the research.

Ownership of data : When research findings could be used to make social policies, which affect people’s lives, should they be publicly accessible? Sometimes, a party commissions research with their interests in mind (e.g., an industry, an advertising agency, a political party, or the military).

Some people argue that scientists should be compelled to disclose their results so that other scientists can re-analyze them. If this had happened in Burt’s day, there might not have been such widespread belief in the genetic transmission of intelligence. George Miller (Miller’s Magic 7) famously argued that we should give psychology away.

The values of social scientists : Psychologists can be divided into two main groups: those who advocate a humanistic approach (individuals are important and worthy of study, quality of life is important, intuition is useful) and those advocating a scientific approach (rigorous methodology, objective data).

The researcher’s values may conflict with those of the participant/institution. For example, if someone with a scientific approach was evaluating a counseling technique based on a humanistic approach, they would judge it on criteria that those giving & receiving the therapy may not consider important.

Cost/benefit analysis : It is unethical if the costs outweigh the potential/actual benefits. However, it isn’t easy to assess costs & benefits accurately & the participants themselves rarely benefit from research.

Sieber & Stanley advise that researchers should not avoid researching socially sensitive issues. Scientists have a responsibility to society to find useful knowledge.

• They need to take more care over consent, debriefing, etc. when the issue is sensitive.
• They should be aware of how their findings may be interpreted & used by others.
• They should make explicit the assumptions underlying their research so that the public can consider whether they agree with these.
• They should make the limitations of their research explicit (e.g., ‘the study was only carried out on white middle-class American male students,’ ‘the study is based on questionnaire data, which may be inaccurate,’ etc.
• They should be careful how they communicate with the media and policymakers.
• They should be aware of the balance between their obligations to participants and those to society (e.g. if the participant tells them something which they feel they should tell the police/social services).
• They should be aware of their own values and biases and those of the participants.

Arguments for SSR

• Psychologists have devised methods to resolve the issues raised.
• SSR is the most scrutinized research in psychology. Ethical committees reject more SSR than any other form of research.
• By gaining a better understanding of issues such as gender, race, and sexuality, we are able to gain greater acceptance and reduce prejudice.
• SSR has been of benefit to society, for example, EWT. This has made us aware that EWT can be flawed and should not be used without corroboration. It has also made us aware that the EWT of children is every bit as reliable as that of adults.
• Most research is still on white middle-class Americans (about 90% of research is quoted in texts!). SSR is helping to redress the balance and make us more aware of other cultures and outlooks.

Arguments against SSR

• Flawed research has been used to dictate social policy and put certain groups at a disadvantage.
• Research has been used to discriminate against groups in society, such as the sterilization of people in the USA between 1910 and 1920 because they were of low intelligence, criminal, or suffered from psychological illness.
• The guidelines used by psychologists to control SSR lack power and, as a result, are unable to prevent indefensible research from being carried out.
