Investigating the Meaning and (Cost-)Effectiveness of Dutch Recovery Colleges
An observational study of Severe Mental Illness and Mental Vulnerabilities, run by Tilburg University at 4 sites in Netherlands.
Trial 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.

- All sexes
- No healthy volunteers
- Adult, Older adult
Study population: RC population (RC Group): Partakers in any way from these four Recovery Colleges: Enik Recovery College, Fameus, Korak, Herstelacademie Haarlem en Meer. PPG population (Control Group): National panel for which participants are recruited via mental health care facilities and Regional Institutes for Protected Living (RIPLs).
Who may be able to join
- For RC group: needs to attend one of the four participating RCs regularly, at least more than once.
- Needs to experience severe mental illness/psychological vulnerabilities (both self-reported or officially diagnosed).

About this study
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.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

Questions about this trial
What is this clinical trial studying?
An observational study of Severe Mental Illness and Mental Vulnerabilities, run by Tilburg University at 4 sites in Netherlands.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 13 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Empowerment (time frame: t0 = baseline, t1= 1 year later, t2 = 2 years later.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05620212, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Aug 2025.
