Participant Selection for Qualitative Research

To prepare for this Discussion:

  • There are “rules of thumb” that guide each qualitative approach. Review Patton’s chapter on sampling types, and study sampling strategies in research articles on the approach you have chosen.
  • Review the articles on data saturation and theoretical saturation, and consider which criteria you will follow to estimate “how many.” Remember, in qualitative research, one case can be enough. If your phenomenon is complex or you are interested in a range of experiences, then you will need more cases.
  • Reflect on your research problem and question. What are the essential characteristics of participants that you want to recruit?

Research Question

What are the lived experiences of stable recovery through on-line rehabilitation services for women with substance use disorders living in rural north Georgia?

The nature of this study will be qualitative inquiry with a phenomenological approach that will focus on the lived experiences of women living in rural north Georgia who utilize online treatment for recovery from substance use disorder.

Sources and Types of Data

  • Data will be collected with semi-structured in depth one-on-one interviews.
  • Transcription of the audio recording used during the interview process of data collection will be used
  • Observations from the interviews

Prepare a Discussion post in which you address the following:

  • Present the most current version of your research question and state the phenomenon of interest.
  • Describe the criteria for inclusion and exclusion.
  • Describe in detail the choices for sample size, data saturation, and theoretical saturation. Justify your choices with citations of research studies that use the same strategy and/or of methodological articles that describe the rationale.
  • Put yourself in the participant’s position, and consider the assurances you would want to hear to ensure that your privacy is respected and that your identity will not be revealed when the study is published. Include those assurances in your invitation.
