Themes, variables, and the limits to calculating sample size in qualitative research: a response to Fugard and Potts (2015, background): “Guest, Bunce, and Johnson (2006) are very careful to place boundaries around how their experiment may be interpreted.”
Transparency and replicability in qualitative research: The case of interviews with elite informants (2019, background): “As an illustration, Guest et al. (2006) described how adding interviews resulted in novel codes and how they decided that theoretical saturation was reached (i.e., the codes generated after the 12th interview were variations of already existing themes).”
Making sense of blockchain technology: How will it transform supply chains? (2019, methodology): “Following guidelines on purposive sampling and data saturation (Francis et al., 2010; Guest et al., 2006; Glaser and Strauss, 2017) and considering our resource and time constraints, we used an initial target number of interviews of between 10 and 20.”
Quantifying Thematic Saturation in Qualitative Data Analysis (2018, background): “Guest (2006) identified the need for a generalizable, numerical metric for saturation, and several methods have been proposed to quantify saturation or to address the related problem of predetermining appropriate numbers of observations for qualitative research.”
What Influences Saturation? Estimating Sample Sizes in Focus Group Research (2019, neutral): “This goal contributes to continual calls for an evidence base of empirical research on saturation (Carlsen & Glenton, 2011; Guest et al., 2006; Kerr et al., 2010; Morse, 1995).”
The economics of COVID-19: initial empirical evidence on how family firms in five European countries cope with the corona crisis (2020, methodology): “further data collection did not generate new insights (Boddy, 2016; Eisenhardt, 1989; Guest et al., 2006; Morse et al., 2002).”
An Examination of the Sufficiency of Small Qualitative Samples (2018, background): “Extending Guest et al.’s (2006) findings to cross-cultural research, Hagaman and Wutich (2016) considered 3 repetitions of a theme by different interviewees as identification of that theme, and found that 16 interviews were enough to identify themes from homogeneous groups with 20-40 needed to ident”
Qualitative Research in Sport Psychology Journals: The Next Decade 2000-2009 and Beyond (2012, methodology): “For example, do sport psychology researchers actually confirm or challenge the ‘methodological orthodoxy’ noted by Hesse-Biber (2010) in how mixed methods is practiced? This orthodoxy currently favors, “quantitative methodologies, with a mixed methods praxis that positions qualitative methods second”
Examining how model youth sport coaches learn to facilitate positive youth development (2014, background): “The original objective of this study was to recruit approximately 12 participants, given that Guest, Bunce, and Johnson (2006) indicated that experiential saturation usually occurs within the first 12 interviews in studies, using thematic analysis and non-probabilistic sampling.”
