Stigma and Peer-Led Interventions: A Systematic Review and Meta-Analysis.

Area of Science:

• Mental Health Research
• Psychology
• Public Health Interventions

Background:

• Self-stigma poses a significant barrier for individuals with mental health problems.
• Peer-led interventions are increasingly explored as a means to mitigate stigma and improve outcomes.
• Understanding the multifaceted impact of these interventions is crucial for evidence-based practice.

Approach:

• A systematic review and meta-analysis of randomized controlled trials (RCTs) were conducted.
• Searched five electronic databases from 1975 to 2021 for relevant literature.
• Analyzed the effects of peer-led interventions on self-stigma, clinical symptoms, recovery, and disclosure outcomes.

Key Points:

• Peer-led interventions demonstrated a significant positive effect on reducing self-stigma and stress associated with stigma.
• Improvements were noted in self-efficacy and the willingness to seek professional help.
• The Honest Open Proud (HOP) subgroup showed significant positive effects on confidentiality and reduced distress related to disclosure.

Conclusions:

• Peer-led interventions are effective in reducing self-stigma and stigma pressure, potentially improving recovery and empowerment.
• These interventions enhance self-efficacy and professional help-seeking but do not significantly affect clinical symptoms.
• The HOP intervention specifically shows benefits for disclosure-related confidentiality and distress.
