In qualitative research, a member check, also known as informant feedback or respondent validation, is a technique used by researchers to help improve the accuracy, credibility, validity, and transferability (also known as applicability, internal validity, or fittingness) of a study. There are many subcategories of members checks, including: narrative accuracy checks, interpretive validity, descriptive validity, theoretical validity, and evaluative validity. In many member checks, the interpretation and report (or a portion of it) is given to members of the sample (informants) in order to check the authenticity of the work. Their comments serve as a check on the viability of the interpretation. Member checking can be done during the interview process, at the conclusion of the study, or both to increase the credibility and validity (statistics) of a qualitative study. The interviewer should strive to build rapport with the interviewee in order to obtain honest and open responses. During an interview, the researcher will restate or summarize information and then question the participant to determine accuracy. Member checks completed after a study are completed by sharing all of the findings with the participants involved. This allows participants to critically analyze the findings and comment on them. The participants either affirm that the summaries reflect their views, feelings, and experiences, or that they do not reflect these experiences. If the participants affirm the accuracy and completeness, then the study is said to have credibility. These member checks are not without fault, but serve to decrease the incidence of incorrect data and the incorrect interpretation of data. The overall goal of this process is to provide findings that are authentic, original and reliable.
Positive aspects of member-checking Member checking provides an opportunity to understand and determine what the author intended to do through their actions. It gives them the ability to correct errors and challenge what are perceived as wrong interpretations. Member checking provides the opportunity to volunteer additional information which may be stimulated by the playing back process. Gets respondent on the record with their reports. Provides people that respond the opportunity to assess adequacy of data and preliminary results as well as to confirm particular aspects of the data. The ability to summarize the preliminary findings. The major problem with member checking however is that it relies on the assumption that there is a fixed truth of reality that can be accounted for by a researcher and can be confirmed by a respondent, which may not be true. In fact, member checks are not consistent with the philosophy of non positivistic qualitative research methods. See positivism for more information on philosophy of approach.
Interviewing and member checking There are two interview styles to promote discussion between interviewees and the interviewers during member checks. The first, Confrontation Style is only effective when there is a trusted, warm, and open relationship between the interviewer and the interviewee. This style promotes discussion empowering the interviewee to have confidence to "fight back" when his/her opinion is questioned. The second, Dialogue and Power, focuses on the inherent power struggle between the interviewer and the interviewee. Interviewers must be aware of this imbalance of power and promote discussion from the interviewee by valuing opinions and reinforcing equal collaboration between the two. In an informal sense, member checks are carried out verbally throughout the conduct of fieldwork. The researcher constantly checks his or her understanding of the phenomenon by utilizing techniques such as paraphrasing and summarization for clarification. It is best to ask permission to visit the participant again at the time of the unstructured interview. Interviews are used as a way for the respondent to express their emotions and thoughts about their experiences and allow the interviewer to have a better understanding of a situation. When the member check procedure is used in a sample of people who were not the original participants in the study, the procedure can be used to assess transferability. If the people who were not the original participants do not agree with the information, then the findings can be said to be biased or not transferable since transferability is the process of being able to apply the findings from one study to others in similar situations. A question to ask is whether the findings "ring true" in others' experiences. It is critical to use member checking in qualitative research studies because these types of studies often involve interpretation. Thus, without allowing participants to validate the accuracy of their findings, one-sidedness will become a major concern. Since the most important issue in evaluating the rigor of qualitative research is trustworthiness, using the strategy of member checks, (along with other techniques such as independent audit, prolonged engagement, triangulation, peer debriefing), is critical to minimizing distortion. Prolonged engagement aids in the ability to detect and account for distortions that might be in the data. It also helps to become oriented to the situation so content is appreciated and the researcher builds trust. In general, member checks are a useful function in research, especially when there are questions about the adequacy of understanding based on limited time of exposure. Thus, a member check can serve to counterbalance concerns about whether engagement was sufficiently prolonged.
Advantages and disadvantages of member checks
Advantages The greatest advantage in a member check is that the researcher can verify the entirety and completeness of the findings, which is a measurable tool of the accuracy of the findings. Other Advantages:
