Design of the present qualitative study
The present study had a qualitative design and we conducted interviews with SOs who had completed at least two of the four modules in SPARE. For other eligibility criteria, see [We used a semi-structured interview guide with open-ended questions. The interview started with the broad question After completing the 12-week follow-up assessment (see [The characteristics of the interviewed SOs are presented in Table SO characteristicsWe conducted all interviews in 2019–2020, either face-to-face, via videoconference, or by telephone. The interviews lasted approximately 45–60 min. We recorded all interviews and they were subsequently transcribed verbatim by a professional transcriber. We sent written information to all SOs in advance, and read through the study information together with the SOs before commencing the interviews.We analyzed the transcripts using conventional qualitative content analysis (hereafter “conventional content analysis”) as described by Hsieh and Shannon [First, we read the transcribed interviews from beginning to end several times. Next, we read the texts more thoroughly to identify codes that were present in the text, or create codes consisting of a few words to encapsulate the meaning of a certain sentence. Within each content area, we investigated the relationships between the codes and jointly discussed and formulated suggested categories and subcategories.Quotes are presented in the results section to increase the transparency of the analysis and facilitate assessment of the study’s credibility and transferability.
