Die Stoppkarte für qualitative Sättigung

Jede Zeile nennt eine Aussage zu dieser Abbildung, ihre Quelle und die Art ihrer Prüfung.

• A SAU18-C1 Saturation is widely used to indicate that more data are unnecessary, and the authors say the concept is used inconsistently: "It is commonly taken to indicate that, on the basis of the data that have been collected or analysed hitherto, further data collection and/or analysis are unnecessary", yet "there appears to be uncertainty as to how saturation should be conceptualized, and inconsistencies in its use"Saunders et al. (2018)
• A SAU18-C2 The article distinguishes different conceptualisations rather than treating saturation as one universal event: "We identify four distinct approaches to saturation, which differ in terms of the extent to which an inductive or a deductive logic is adopted"Saunders et al. (2018)
• A SAU18-C3 The recommendation is to make the form and rationale explicit: "We conclude that saturation should be operationalized in a way that is consistent with the research question(s), and the theoretical position and analytic framework adopted"Saunders et al. (2018)
• A HK22-C1 The design is a systematic review, in the authors' words: "We conducted a systematic review of four databases to identify studies empirically assessing sample sizes for saturation in qualitative research", and "We identified 23 articles that used empirical data (n = 17) or statistical modeling (n = 6) to assess" saturationHennink & Kaiser. (2022)
• A HK22-C2 The reviewed range, verbatim: "Studies using empirical data reached saturation within a narrow range of interviews (9-17) or focus" group discussions (4-8), particularly in relatively homogeneous populationsHennink & Kaiser. (2022)
• A HK22-C3 The caution is the authors' own and travels with the range: "these findings apply to certain types of studies (e.g., those with homogenous study populations)"Hennink & Kaiser. (2022)
• A VR17-C1 The simulation's object, in the author's words: "I conceptualize a population as consisting of sub-populations that contain different types of information sources that hold a number of codes"van Rijnsoever. (2017)
• A VR17-C2 The three sampling scenarios differ in what they require: "the minimal and maximal information scenarios are significantly more efficient than random chance", though they yield fewer repetitions per codevan Rijnsoever. (2017)
• A VR17-C3 The result that decides the guidance: "I show that theoretical saturation is more dependent on the mean probability of observing codes than on the number of codes in a population"van Rijnsoever. (2017)
