Effect of Occupational Therapy on Psychosocial Parameters and Functioning in Individuals With Severe Mental Illness

Severe mental illness (SMI), including schizophrenia spectrum disorders and bipolar disorder, is associated with significant impairments in psychosocial functioning, daily life participation, self-efficacy, and social functioning. Despite pharmacological treatment, many individuals continue to experience limitations in social relationships, occupational roles, independent living activities, and overall functioning. Psychosocial rehabilitation interventions are therefore important components of comprehensive mental health care. Occupational therapy aims to improve individuals' participation in meaningful daily activities, enhance occupational performance, strengthen social roles, and support recovery. However, evidence regarding the effects of occupational therapy interventions on internalized stigma, self-efficacy, and personal and social functioning among individuals with SMI remains limited. This randomized controlled trial aims to investigate the effects of a structured occupational therapy group intervention on internalized stigma, self-efficacy, personal and social functioning, occupational performance, and instrumental activities of daily living in individuals with SMI receiving services at a Community Mental Health Center. Eligible participants will be randomly assigned to either an intervention group or a control group. The intervention group will participate in a seven-session occupational therapy group program, with one 60-90-minute session per week, while the control group will continue to receive routine Community Mental Health Center services. The intervention addresses self-awareness and identity, internalized stigma, personal strengths and self-efficacy, daily life roles, role performance, goal setting, and social participation through structured group activities and psychoeducational components. Outcomes will be assessed before the intervention and after the seven-week intervention period using validated measures of internalized stigma, self-efficacy, personal and social functioning, occupational performance and satisfaction, and instrumental activities of daily living. It is hypothesized that participants receiving the occupational therapy intervention will demonstrate reduced internalized stigma and improved self-efficacy and personal and social functioning compared with participants receiving routine services alone.
