The measurement strategy includes three sets of assessment interviews from both IPS and TAU clients. The Master's-level RA (research assistant), who will have clinical experience, will collect all data in the first two years. In the third year, a new RA with health economics skills will collect the utilization and social/recreational data, while an unpaid practicum student in Clinical Psychology completes the clinical interviews. Data collection will be blinded, i.e. the RA's will not know whether the client is in the IPS or vocational-service-as-usual group.
