Characteristics of the peer volunteers.

Despite the evidence for the effectiveness of psychosocial interventions for perinatal depression, their uptake is low in Low- and Middle-Income Countries. Reasons for this include the lack of contextually adapted interventions and mental health specialists to deliver them. This study aimed to test the acceptability and feasibility of a psychosocial intervention for perinatal depression, the Thinking Healthy Programme–Peer Delivered, adapted for use in rural Malawi. A multi-method evaluation of feasibility and acceptability of the intervention was conducted using a one-group pretest-posttest quasi-experimental design and an exploratory qualitative study. Pre-post intervention change in depression scores (paired t-test) and recruitment, retention and session adherence rates were calculated. Qualitative data were collected through 29 in-depth interviews (22 mothers and 7 peer volunteers) and 1 Focus Group Discussion (18 mothers). Thematic analysis approach was used to analyse qualitative data. Seven (7) out of 8 peer volunteers were successfully trained to deliver the intervention. A total of 31 pregnant women with Edinburgh Postnatal Depression Scale (EPDS) score ≥12 were offered intervention, of whom 24 were enrolled (recruitment rate 77.4%). Out of these 24 women, 22 completed the intervention (retention rate 91.6%). Mean difference between pre- and post-test EPDS scores one week after 8th session was 7.59 (95% CI 4.98 to 10.19), p
