NCT ID NCT05927987
First seen Jul 08, 2026 · Last updated Jul 09, 2026 · Updated 1 time
Summary
This pilot study tests whether a brief psychological program called Problem Management Plus (PM+) can help reduce anxiety and depression symptoms in people held in Dutch remand prisons. The program, developed by the World Health Organization, teaches problem-solving, stress management, and social support skills over five sessions. Researchers will compare prisoners who receive PM+ plus usual care to those who receive only usual care, focusing on whether the program is feasible and acceptable in this setting.
