The Evidence Base

Peer-Reviewed Research & Real-World Results

The landscape of substance use disorder treatment is changing. The most effective programs now combine rigorous clinical care with structured, evidence-based interventions grounded in lived experience—not just guest speakers, but proven tools that support real client progress.

At GBB Inspirational Recovery, we ground our approach in both national research and decades of hands-on experience. By blending clinical best practices with real-world recovery insights, we show how lived experience can support clients in meaningful ways. The result? Programs that can strengthen engagement, retention, and more sustainable client outcomes. Below are key findings and real-life case examples showing how integrating lived experience with clinical care can transform recovery. Review the evidence and use it to strengthen your program today.

What the Research Says

Peer support works — and the research is honest about what it does best. The strongest, most consistent finding isn’t abstinence rates. It’s engagement: keeping people connected to recovery after treatment. That’s the mechanism everything else depends on.

  

  • Eddie et al. (2025), Current Addiction Reports — Systematic review of peer recovery support services for substance use disorder. The most consistent signal across studies: peer support improves treatment linkage and engagement, in inpatient and outpatient settings alike. Direct effects on substance use were mixed.                                     
  • Byrne et al. (2020), Drug and Alcohol Dependence — Pilot randomized trial linking inpatients to peer recovery coaching. Recovery-support engagement: 84% vs. 34% at 30 days; 80% vs. 24% at six months. No demonstrated difference in substance use itself — the win is engagement.                                                                                                                         
  • Kelly, Humphreys & Ferri (2020), Cochrane Review — 27 studies, 10,565 participants on AA and 12-step facilitation for alcohol use disorder. Structured facilitation achieved about 42% vs. 35% continuous abstinence at 12 months against other treatments. A real edge — not a doubling.                                                                                                         
  • SAMHSA TIP 64 (2023) — Federal guidance: “Any setting that offers care and support for individuals who have problematic substance use should also offer or arrange for” peer support services.
