3.4 DATA COLLECTION
The data are the product of 11 semi-structured interviews and 4 focus groups. Based on PRECEDE-PROCEED model and occupational stress literature, a semi-structured interview guide was designed (See Supplement 2). The average duration of interviews and focus groups was 60 minutes. Interviews and focus groups were recorded, and audio content was transcribed on the same day. Data collection continued until theoretical saturation was reached. In other words, when no new information was found (Nascimento et al., 2018). One interview was repeated due to the need to clarify and explain an issue.
All interviews and focus groups were conducted by the first author (female/PhD of Science in Health Education and Health Promotion). To ensure the clarity and simplicity of the interview guide questions and to evaluate the interviewer’s ability, two interviews and a focus group were conducted experimentally. However, the data were not included in the results of the study. In order to establish credibility of the interview, the initial semantic units were presented to the participants for approval.
