Study summary

Recovery colleges (RC) aim to promote the recovery of people who experience mental vulnerabilities. Rather than facilitating treatment of illness (as regular mental health care services [MHCS] do), RCs are learning environments, with a special focus on peer support and co-creation. While MHCS are founded on scientific and professional knowledge, RCs value the knowledge and abilities of those with lived experiences as such. By sharing experiences, RC attendees can inspire and support each other (hence 'peer support') and they can use their experiences to contribute to the educational program (hence 'co-creation'). In the Netherlands RCs are 100% peer run, meaning that no mental health care workers are involved.

Despite promising premature findings on the effectiveness of RC attendance (e.g., positive impacts on MHCS use, mental wellbeing and functioning, quality of life, empowerment and more), large, controlled studies are extremely scarce. Furthermore, the way RCs are managed in the Netherlands seems to differ from the RCs that have been studied before. While RCs in some countries are a coproduction of peers and mental health practitioners, RCs in the Netherlands are 100% peer run, although they are usually hosted by MHCS. In turn, this research project aims to investigate the (cost-)effectiveness of RCs in the Netherlands. In terms of effectiveness, we expect that RC attendance improves feelings of empowerment. Besides, we investigate impacts on quality of life, mental health, loneliness, satisfaction with treatment and support and self-stigma. We also determine the cost-effectiveness of Dutch RCs.

Read the detailed description

This quantitative study is part of a larger research project that entails qualitative analysis of:

  • the meaning of Enik RC for its partakers (the first RC established in the Netherlands in 2015);
  • the position that RCs can and should have in the Dutch MHCS landscape;
  • a fidelity measure to define the core elements of Dutch RCs and to obtain an overview of the available initiatives in the Netherlands

The research project is executed in close collaboration with co-researchers who are partakers of Enik RC. The findings of the pre-registered quantitative study will be evaluated and contextualized in co-creation as such.

NOTE: The Observational Study Model is both Cohort (monitoring for a period of 2 years) and Case-Control (comparing RC partakers with non-partakers).

NOTE: Enik Recovery College has 7 established locations in the region of Utrecht at the time of our recruitment. All are included.

NOTE: Fameus has 4 established locations (Breda 2x, Tilburg, Roosendaal). All are included.

NOTE: This study is conducted both by Tilburg University (Department Tranzo) and Trimbos-institute (Department of Reintegration and Community Care) as primary organizations. The PI is also affiliated with both.

NOTE. The aimed sample size at t0 is N=120 in the RC condition. So 120 partakers of RCs will be matched with members from the PPG.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Mar 2022 to primary completion in Jan 2025, 34 months.

Of 149 non-industry observational studies under Mental Disorders, half reached primary completion within 37 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 77. This study's 34 months is close to that.

Counting every sponsor, half of 156 studies reached it within 37 months; a quarter within 13 and three quarters within 77.

Mental Disorders covers many different conditions, not one, so the studies compared here vary widely. Read these figures as a rough guide.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 13, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
