What this Trial Is About

Given the high prevalence of mental health issues, such as anxiety and depression, in pretrial detainees, the Swiss Federal Justice Department (SFJD) approved a model trial ("Modellversuch Untersuchungshaft", MV). The MV will be carried out in 11 pretrial detention facilities in the cantons of Zurich and Bern and aims to improve the wellbeing and social integration of individuals in pretrial detention. As part of the MV the investigators are evaluating the impact of two interventions using a randomized controlled trial (RCT). The first intervention, "Prison Stress Management" (PRISMA), addresses the issue of poor mental health of inmates during pretrial detention and after release. PRISMA is a scalable World Health Organization (WHO)-developed psychological intervention based on cognitive-behavioral therapy (CBT) program and goes beyond the status-quo mental health support offered in jails. Currently, only inmates with severe mental health problems are referred to the psychiatric ward of the health services provided in jails and no continuation of support is offered after the transition to the outside world. The second intervention (SOCIAL) uses extended social services to address potential disruptions incarceration might cause in detainees' social and economic lives. The isolation from the outside world implies that detainees might lose their jobs and housing, their relationships with their family and friends are strained, all factor hindering re-integration into society and taxing their mental wellbeing. This project will provide much needed insights to criminal justice authorities to design detention facilities and the detention experience in ways that empower incarcerated individuals to cope with the disruptions and psychological stress that come along with their detention.
