This multicenter randomized controlled trial examined the mechanisms of peer support (PS) in improving recovery outcomes among 565 adults with severe mental health conditions across various income settings. The study found that PS significantly influenced personal recovery through enhanced social inclusion (β = 0.114) and hope (β = 0.037), although no direct effects on recovery or health functioning were observed.
Key findings
- PS had significant indirect effects on personal recovery via social inclusion (β = 0.114).
- Hope also mediated the relationship between PS and personal recovery (β = 0.037).
- Health and social functioning improved indirectly through social inclusion (β = -0.035) and hope (β = -0.026).
- Participants with lower baseline hope and social inclusion benefited more from PS.
Why it matters
Understanding the mechanisms through which peer support operates can enhance the design of mental health interventions. By targeting social inclusion and hope, clinicians can better support recovery in individuals with severe mental health conditions.
