What this trial studies

This pilot randomized controlled trial aims to assess the feasibility and acceptability of the World Health Organization's Problem Management Plus (PM+) intervention, specifically adapted for individuals in Dutch remand prisons. The study will compare two groups: one receiving the PM+ intervention alongside standard care and the other receiving only standard care. Researchers will evaluate the effectiveness of the intervention in reducing symptoms of anxiety and depression among participants. The study also includes a qualitative component to further understand the implementation process.

Who should consider this trial

Good fit: Ideal candidates are Dutch-speaking adults aged 18 and older who are currently detained in a Dutch remand prison and experiencing elevated psychological distress.

Not a fit: Patients with severe mental disorders, acute medical conditions, or those currently enrolled in specialized psychological treatment programs may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly improve mental health outcomes for incarcerated individuals, potentially reducing recidivism rates.

How similar studies have performed: While this approach is novel in the prison context, similar interventions have shown promise in other settings for addressing mental health issues.
