Psychosocial interventions are one of the main ways that participation and performance in occupations can be addressed within the occupational therapy treatment of individuals with SMI. In those who have an SMI, occupational performance and participation can be impacted due to symptomology and by the stigma of living with SMI, ultimately leading to occupational injustice. The current review analyzed 25 studies that implemented a psychosocial intervention in their treatment for those diagnosed with an SMI. The review identified three categories of psychosocial interventions (cognitive-based, skills training, and occupation-based) with six subcategories: metacognition, cognitive remediation, psychoeducation, social skills, life skills, and vocational rehabilitation. Findings reveal a strong level of evidence for the use of psychosocial interventions in supporting occupational performance and ultimately increasing occupational justice for individuals with SMI. The current review supports the use of psychosocial intervention approaches which can guide occupational therapy practitioners working with SMI populations.en-USOccupational TherapySerious Mental IllnessSchizophreniaPsychosocialOccupational PerformanceOccupational JusticeStigma
