An
important element of qualitative studies is trustworthiness. In this section of
c. 4, you will describe how you went about implementing the strategies and
plans that you laid out in c. 3. Let's review the commonly used methods.
Credibility,
which is comparable to internal validity. This is getting at the credibility of
your data, common methods used are triangulation, prolonged contact, member
checks, and saturation. You want to show that your data are as accurate as
possible.
Transferability,
which is comparable to external validity. This is getting at the
generabilizability of your data to other groups. Common methods used are thick
description and a variation in participant selection.
Dependability,
comparable to reliability. You want to show the accuracy of your data methods, common
methods are audit trails and triangulation. Triangulation is accomplished by
asking the same research questions of different study participants and by
collecting data from different sources and by using different methods to answer
those research questions. Member checks occur when the researcher asks
participants to review both the data collected by the interviewer and the
researchers' interpretation of that interview data. Participants are generally
appreciative of the member check process, and knowing that they will have a
chance to verify their statements tends to cause study participants to fill in
any gaps from earlier interviews.
Confirmability,
comparable to objectivity. This is the degree to which the findings are the
product of the focus of the study and not of the biases of the researcher One
way to do this is through an audit trail. An adequate trail (or records) should
be left to enable the auditor to determine if the conclusions, interpretations,
and recommendations can be traced to their sources and if they are supported by
the inquiry.
Next time we will look at Chapter 4 quantitative analysis.
Do you have an issue or a question that you would like me to discuss in a
future post? Would you like to be a guest writer? Send me your ideas!
