RECRUITMENT
Qualitative data sources included field notes taken by local site coordinator and in-depth interviews conducted with the participating women and nurses. In-depth interviews were carried out after the end-point outcome assessments. Women’s motivation for participation, their experience of group work, views on the intervention (timing, duration, frequency and content), facilitators’ experience of delivering the group sessions, perceived benefits of the programme, and how the intervention could be improved were explored in the interviews.Participants for qualitative interviews were purposively selected by the site coordinator through the study database to ensure heterogeneity in reference to number of sessions attended. All selected participants agreed to be interviewed except women who attended no sessions following recruitment. Informed consent was obtained online. To avoid potential bias, two independent researchers (SH, DS) who were not involved in the study conducted the in-depth interviews online with twelve women and two nurse facilitators after reaffirming their consent verbally. The interviews were aided by a pre-defined semi-structured interview guide based on previous research on cultural adaptation studies of the original THP [The interview guide was pilot tested before being finalized to ensure that questions within each dimension were generating relevant information. All interviews were audio recorded, transcribed and checked back against the original audio recordings for accuracy. Interviews lasted between 45 to 60 minutes.
