A randomized controlled trial comparing two vocational models for persons with severe mental illness

Area of Science:

• Psychiatry
• Vocational Rehabilitation
• Mental Health Services

Background:

• Severe mental illness often presents challenges to sustained competitive employment.
• Vocational rehabilitation models aim to improve employment outcomes for this population.
• Comparing different rehabilitation strategies is crucial for evidence-based practice.

Purpose of the Study:

• To compare the effectiveness of the Individual Placement and Support (IPS) model versus the Diversified Placement Approach (DPA) for vocational rehabilitation in individuals with severe mental illness.
• To evaluate competitive and paid employment outcomes over a two-year period.

Main Methods:

• A randomized controlled trial involving 187 unemployed participants with severe mental illness.
• Participants were assigned to either the IPS model or the DPA.
• Outcomes were assessed over a two-year follow-up period.

Main Results:

• The Individual Placement and Support (IPS) model achieved significantly higher competitive employment rates (75.0%) compared to the Diversified Placement Approach (DPA) (33.7%).
• No significant difference was found between IPS and DPA in terms of paid employment outcomes.
• The study highlights differential effects of rehabilitation models on employment types.

Conclusions:

• The Individual Placement and Support (IPS) model is more effective than the Diversified Placement Approach (DPA) for achieving competitive employment outcomes in individuals with severe mental illness.
• While IPS excels in competitive employment, neither model demonstrated superiority for general paid employment.
• Findings suggest IPS as a preferred model for competitive employment in this population.
