- An Examination of the Sufficiency of Small Qualitative Samples (2018, result): “Examining this same question with focus group data, as opposed to individual interviews as in the earlier study, Guest, Namey, and McKenna (2016) found that 60% of their 94 codes were found in the first focus group, 84% in the first 3 groups, and 90% by 6.”
- Qualitative Methods in Implementation Research: An Introduction (2019, background): “Typically, 4–6 focus groups will prove adequate, depending on the diversity of participants (Guest et al., 2017).”
- A simple method to assess and report thematic saturation in qualitative research (2020, background): “This study included 40 individual interviews with African American men in the Southeast US about their health seeking behaviors [29].”
- Saturation controversy in qualitative research: Complexities and underlying assumptions. A literature review (2020, methodology): “The importance of saturation in qualitative research is explicated from two seemingly related angles: sample size determination (Guest et al., 2006, 2017) and enhancement of research quality and validity (Hancock et al., 2016).”
- Can sample size in qualitative research be determined a priori? (2018, background): “Parse (2009) Recommends 2 to 10 participants in order to achieve ‘redundancy or saturation’ (p.”
- What Influences Saturation? Estimating Sample Sizes in Focus Group Research (2019, methodology): “Guest, Namey, and McKenna (2016) used data from a study with 40 focus group discussions to develop empirically based recommendations on sample sizes for focus group studies.”
