Ethical Considerations in Psychology Research

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:

  1. Department Ethics Committee (DEC): for most routine research.
  2. Institutional Ethics Committee (IEC): for non-routine research.
  3. 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 both issued a code of ethics in psychology that provides guidelines for the conduct of research.  Some of the more important ethical issues are as follows:

Informed Consent

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.

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 (18ys +) capable of giving permission 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.

However, it is not always possible to gain informed consent.  Where it is impossible for the researcher to ask the actual participants, a
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 there 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.

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.

Debrief

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 not just to provide information but to help the participant leave the experimental situation in a similar frame of mind as when he/she entered it (Aronson, 1988).

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

This is where participants are misled or wrongly informed about the research aims.

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, there are some types of research that cannot be carried out without at least some element of deception.

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

This is sometimes necessary in order 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 ).

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

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

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.

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 will have to be set in the context of the research aims.

Withdrawal from an Investigation

Participants should be able to leave a study at any time 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!

  1. 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.
  2. 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.
  3. The research team. There are examples of researchers being intimidated because of the line of research they are in.
  4. The institution in which the research is conducted.

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

  1. The research question or hypothesis.
  2. The treatment of individual participants.
  3. The institutional context.
  4. 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: 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.
