SESSION, RECRUITMENT, DELETION
Participants who had expressed an interest in the qualitative study (via the recruitment and consent process for the REACT trial) were contacted via telephone and asked to participate in three semi-structured interviews at each time point. The semi-structured, face-to-face interviews were conducted either in participants’ homes or in community centres. At 24-months, all interviews were conducted at participants’ homes. Session leaders took part in individual interviews at 12-months. Interviews were conducted by two experienced PhD interviewers, RC (PhD) and JdK (PhD).Interviews were recorded using an Olympus VN-741PC password-protected encrypted digital recorder, on average lasting 48-minutes (range = 22–89 min). All interview data were immediately transferred to a University of Bath owned password-protected and encrypted server, before deletion from the digital recorder. Interviews were transcribed verbatim and de-identified.
