Code Saturation Versus Meaning Saturation: How Many Interviews Are Enough? (2016, background): “Many factors influence sample sizes for qualitative studies, including the study purpose, research design, characteristics of the study population, analytic approach, and available resources (Bryman, 2012; Malterud, Siersma, & Guassora, 2015; Morse, 2000).”
‘Define, Explain, Justify, Apply’ (DEJA): An analytic tool for guiding qualitative research sample size (2021, methodology): “…2003), their experience, the researcher’s subjective judgment, the quality of information collected (Sandelowski, 1995), the sampling technique adopted (Hagaman & Wutich, 2017; Marshall, 1996; Mason, 2010; J. Morse, 1991), the research strategy adopted (Bernard, 2000; Creswell, 2014; Morse, 2000;)”
Situating and Constructing Diversity in Semi-Structured Interviews (2015, background): “If the “free-flow” of information is reduced, as it is in semistructured interviews, the amount of data obtained from each participant is more limited, hence, the number of participants must be increased to obtain data adequacy (Morse, 2000).”
Characterising and justifying sample size sufficiency in interview-based studies: systematic analysis of qualitative health research over a 15-year period (2018, background): “…30 as an approximate or working number of interviews at which one could expect to be reaching theoretical saturation when using a semi-structured interview approach (Morse 2000), although this can vary depending on the heterogeneity of respondents interviewed and complexity of the issues explored.”
Saturation controversy in qualitative research: Complexities and underlying assumptions. A literature review (2020, background): “Morse (2000) points out that saturation is largely declared and not explained by researchers, notwithstanding that complexities in measuring saturation in real life contexts are immense.”
Can sample size in qualitative research be determined a priori? (2018, background): “(Morse, 2000, p. 4) The way in which, and the extent to which, such shadowed data will influence sample size is not straightforward, and will depend upon the specific approach to analysis that is undertaken.”
What Influences Saturation? Estimating Sample Sizes in Focus Group Research (2019, neutral): “…claiming to have reached saturation in qualitative studies without providing adequate explanation or justification on how saturation was assessed or achieved (Bowen, 2008; Guest et al., 2006; Hennink, Kaiser, & Marconi, 2017; Malterud, Siersma, & Guassora, 2016; Morse, 1995, 2000, 2015).”
