What this trial studies

This initiative aims to address the mental health challenges faced by pretrial detainees in Switzerland through the implementation of the PRISMA program, which is based on cognitive-behavioral therapy strategies developed by the WHO. Conducted in pretrial detention centers in Zurich and Bern, the study evaluates the feasibility and acceptability of this intervention alongside additional social support services. The randomized controlled trial will assess the impact of PRISMA on the psychological wellbeing of inmates, aiming to enhance their mental health during and after detention. The findings will inform a larger-scale trial to improve mental health support for incarcerated individuals.

Good fit: Ideal candidates for this study are pretrial detainees aged 18 and older who are entering detention in the cantons of Zurich and Bern.

Not a fit: Patients who are not fluent in any of the nine languages offered for the PRISMA program or those experiencing acute suicidality may not benefit from this study.

Why it matters

Potential benefit: If successful, this program could significantly improve the mental health and wellbeing of pretrial detainees, aiding their reintegration into society.

How similar studies have performed: Other studies have shown success with similar cognitive-behavioral therapy approaches in improving mental health outcomes in incarcerated populations.
