Feasibility and Acceptability of PRISMA for Prisoners in Switzerland

In response to the significant mental health challenges faced by pretrial detainees, the Swiss Federal Justice Department has initiated a model trial in pretrial detention centres in Zurich and Bern. This model trial, named in German as a \"Modellversuch,\" is designed to enhance detainees\' wellbeing and evaluates various interventions through a randomized controlled trial. The \"Prison Stress Management\" (PRISMA) programme, a key intervention derived from the WHO\'s cognitive-behavioral therapy strategies, seeks to address the lack of mental health support within jails. The goal of this pilot RCT is to evaluate the feasibility and acceptability of PRISMA for inmates inform a full-scale, definitive randomized controlled trial.
