Efficacy of the Individual Placement and Support (IPS) Model

Hypothesis 1. Consumers with disabilities and co-occurring SUD receiving IPS will be more likely to be competitively employed (defined as 1 or more days of work over the past 30 days) at 3, 6 and 12 months following the initiation of vocational treatment goals when compared to a group receiving standard services. Hypothesis 2. Consumers with disabilities and co-occurring SUD receiving IPS when compared to the comparison group will 1.) be more successful in achieving their employment goals as indicated by the ratio of hours worked to desired hours worked; 2.) become competitively employed sooner; 3.) earn higher wages, 4.) have greater job satisfaction, 5.) have greater economic satisfaction; 6.) have greater life satisfaction, 7.) have greater self-esteem, and 8.) have fewer days of using substances during follow-up points.
