Effectiveness of recovery colleges: A nonrandomised clinical trial across two years using propensity score matching

Background: Recovery colleges (RCs) facilitate peer-supported communities where people with lived experience of mental disruption learn collaboratively, aiming to foster empowerment and personal recovery. While existing (qualitative) research relates RC attendance to positive outcomes, high-quality multi-college quantitative studies evaluating RC effectiveness are scarce.

Aims: We examine the extent to which RC attendance impacts empowerment (primary outcome) and other recovery-related outcomes.

Method: In this nonrandomised clinical trial (May 2022 to January 2025), RC partakers from four Dutch RCs were compared with controls over 2 years, in annual data collections. Linear mixed model analyses were conducted to investigate interactions between group and time. Exploratory analyses investigated distinguishing characteristics of RC partakers. This study was embedded in a larger project and was pre-registered (clinicaltrials.gov: #NCT05620212). Academic and experiential researchers collaborated in the design, recruitment, and analysis.

Results: The sample comprised 91 RC partakers and 182 matched controls. RC partakers faced severe or persistent mental health challenges and attended RCs in multiple capacities (e.g., student and visitor/volunteer). Outcomes were mostly stable over time and did not differ between groups. Hence, no group-specific changes over time were found, as shown by interaction terms that were not statistically significant (e.g., empowerment: estimate T1*RC= 0.02, 95% CI= −0.08–0.13, estimate T2*RC= −0.001, 95% CI= −0.11–0.11).

Conclusions: Despite promising qualitative evidence of RC effectiveness, our study found no differences between RC partakers and matched controls in quantitative recovery-related outcomes over time. Factors of influence may be possible pre-study effects, unmeasured confounding, or limitations in how standardised questionnaires capture recovery experiences. Methodologically, the findings raise questions about the operationalisation of effectiveness in the context of personal recovery and flexible, co-created practices such as RCs. Importantly, while this study could not establish measurable effectiveness, this does not automatically imply that RC attendance cannot meaningfully contribute to recovery.
