“…Nineteen of the 29 studies were qualitative and reported on outcomes from the perspectives of service users (Bocking et al, 2018 ; Fallin-Bennett et al, 2020 ; Gidugu et al, 2015 ; Taylor et al, 2018 ), mental health professionals (Agrawal et al, 2016 ; Collins et al, 2016 ; White et al, 2017 ), managers (Byrne et al, 2018 ; Merritt et al, 2020 ), caregivers (Yuen et al, 2019 ), and peer workers themselves (Griffiths & Hancock-Johnson, 2017 ). Several studies combined perspectives from some of the involved actors, either as part of case studies (Collins et al, 2019 ; Davies et al, 2014 ) or through interviews with several stakeholders (Barr et al, 2020 ; Brasier et al, 2022 ; Jack et al, 2018 ; Otte et al, 2019 ; Tseris, 2020 ).…”
