Methodological Strength and Limitations
verbal and nonverbal communication, unformed
The consecutive selection is a strength as it ensures the inclusion of a representative sample of study participants. The substantial number of participants (N=89) has provided us with rich and representative data on expectations. As the question of expectations can be relatively broad, a larger sample is preferable. Regarding the scope of the interviews, some interviews were short, especially for the participants with mainly unformed expectations. Overall, the amount of data was sufficient and manageable, while not being too extensive.All data were collected through interviews. The interviewers had no care relationship with the participants nor had ever met them before the interview, which created a sense of equality in power dynamics and facilitated open unbiased conversations. The interviews were primarily conducted via telephone, which meant body language, facial expressions, and reactions could not be captured. This limitation could have resulted in the interviewer missing opportunities to seek clarification for discrepancies between verbal and nonverbal communication. However, certain forms of response bias are reduced by the fact that the interviewer does not influence the participants through physical presence [To ensure trustworthiness, analyst triangulation was applied, with the researchers independently coding and categorizing data, and each step of the analysis process was discussed until consensus about the interpretation was achieved. A strength of the study is that the participants differed in age, gender, and other sociodemographic variables (eg, previous training experience), which provided a rich variety of information. All data in the interviews relevant to the aim have been included in the analysis. The data were very rich and sufficient to explore a broad range of expectations for tele-yoga.
