Effectiveness of Depression and Substance Use Module for Patients With Co-occurring Disorders

The purpose of this study is to evaluate the adaptation and effectiveness of an integrated treatment module, the Depression and Substance Use Disorder Module (D-SUD-M), for male patients experiencing co-occurring depression and substance use disorders in Pakistan. Participants are divided into two groups: an experimental group receiving the structured D-SUD-M intervention-based sessions and a control group receiving standard routine treatment sessions within the rehabilitation center. The primary objective is to evaluate whether the specialized intervention module significantly reduces depressive symptoms and substance use severity compared to routine standard care.
