Subproject 4: Effectiveness of a culture-sensitive therapy to improve affect regulation in refugees with substance use problems

Aims and benefits

Refugees often report high levels of psychological distress due to post-migration difficulties and traumatic experiences before and during flight. Refugees with hazardous substance use or existing substance use disorder (SUD) are a particularly vulnerable group for whom few preventive and therapeutic measures are available.

The aim of this study is therefore to investigate the effectiveness of an integrative culturally sensitive group therapy approach (STARC-SUD) to improve affect regulation in refugees with substance-related problems.  

More information about the group offer for those affected can be found here.

Additional study information

The study aims to include n = 286 male refugees with psychological distress (GHQ-2 <13) and hazardous substance use or SUD (AUDIT>7 or DUDIT>6), who were subject to psychological distress before or during flight. The intervention is offered to refugees with the support of interpreters in addiction aid facilities in six metropolitan regions on Germany. The effectiveness of STARC-SUD is compared with the treatment as usual (TAU) after the end of the intervention and three months later. It is assumed that STARC-SUD can more greatly reduce psychological distress than TAU. The primary endpoint is severity of psychological distress (GHQ-12).
