Effect of Person-Centered Occupational Therapy Interventions for Substance Use Disorder

The Effect of Person-Centered Occupational Therapy Interventions on Occupational Performance, Self-Efficacy and Psychological Resilience in Substance Use Disorder

This study investigates the impact of person-centered occupational therapy interventions on individuals diagnosed with substance use disorder. Substance use often leads to isolation and difficulties in daily activities such as work, self-care, and leisure time. The research aims to evaluate how a tailored 8-week therapy program affects participants' occupational performance, self-efficacy, and psychological resilience. Participants will be divided into a study group receiving therapy and a control group.

Participants aged 18-65 with a DSM-5 diagnosis of substance use disorder will be recruited from the Erenköy AMATEM unit. The study employs an experimental design with 34 participants (17 in the study group, 17 in the control group). The study group will receive person-centered occupational therapy interventions 3 times per week for a total of 8 weeks.

The intervention process is based on the four stages of person-centered practice: identifying occupational performance problems using the Canadian Occupational Performance Measure (COPM), brainstorming realistic goals, implementing tailored strategies (e.g., time management, vocational skills, or healthy habits), and revising the process based on feedback . Assessment tools including the COPM, Self-Efficacy Scale, and Brief Resilience Scale will be administered at baseline and after the 8-week intervention to measure changes in performance and psychological factors.
