RESUMO
OBJECTIVE: The introduction of peer support in mental health teams creates opportunities and challenges for both peer and non-peer staff. However, the majority of research on mental health workers' (MHWs) experiences with peer support comes from high-income countries. Using Peer Support In Developing Empowering Mental Health Services (UPSIDES) is an international multicentre study, which aims at scaling up peer support for people with severe mental illness in Europe, Asia and Africa. This study investigates MHWs experiences with UPSIDES peer support. DESIGN: Six focus groups with MHWs were conducted approximately 18 months after the implementation of the UPSIDES peer support intervention. Transcripts were analysed with a descriptive approach using thematic content analysis. SETTING: Qualitative data were collected in Ulm and Hamburg (Germany), Butabika (Uganda), Dar es Salaam (Tanzania), Be'er Sheva (Israel) and Pune (India). PARTICIPANTS: 25 MHWs (19 females and 6 males) from UPSIDES study sites in the UPSIDES Trial (ISRCTN26008944) participated. FINDINGS: Five overarching themes were identified in MHWs' discussions: MHWs valued peer support workers (PSWs) for sharing their lived experiences with service users (theme 1), gained trust in peer support over time (theme 2) and provided support to them (theme 3). Participants from lower-resource study sites reported additional benefits, including reduced workload. PSWs extending their roles beyond what MHWs perceived as appropriate was described as a challenge (theme 4). Perceptions about PSWs varied based on previous peer support experience, ranging from considering PSWs as equal team members to viewing them as service users (theme 5). CONCLUSIONS: Considering local context is essential in order to understand MHWs' views on the cooperation with PSWs. Especially in settings with less prior experience of peer support, implementers should make extra effort to promote interaction between MHWs and PSWs. In order to better understand the determinants of successful implementation of peer support in diverse settings, further research should investigate the impact of contextual factors (eg, resource availability and cultural values).
