Effect of Person-Centered Occupational Therapy Interventions for 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.

About this study

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.

Treatment and study plan

Awareness Training

Behavioral

A single-session educational program designed to increase awareness about the consequences of substance use and the recovery process.

Person-Centered Occupational Therapy

Behavioral

An 8-week person-centered program (3 sessions per week) focusing on daily life activities, productivity, and leisure goals identified through the COPM.

Primary outcomes

  1. Canadian Occupational Performance Measure (COPM)

    Time frame: Change from baseline at 8 weeks.

    A semi-structured interview used to identify and prioritize everyday activities that the individual finds difficult to perform. It measures two components: Occupational Performance and Satisfaction. Both are scored on a scale of 1 to 10, where higher scores indicate better performance and higher satisfaction.

Secondary outcomes

  1. Self-Efficacy Scale

    Time frame: Change from baseline at 8 weeks.

    A 23-item scale measuring the individual's self-judgment of their ability to achieve intended goals. Scores range from 23 to 115, with higher scores indicating higher self-efficacy.

  2. Brief Resilience Scale

    Time frame: Change from baseline at 8 weeks

    A 6-item self-report scale measuring the individual's ability to bounce back or recover from stress. Higher scores indicate higher psychological resilience.
