Dependent variables were two vocational outcome measures: competitive employment and work for 40 or more hours in a single month. All experimental programs integrated psychiatric treatment and vocational services. An Employment Intervention Demonstration Program measure was developed to operationalize the level of integration. In addition, the effects of the number of hours of psychiatric and vocational services were examined separately. A running cumulative total of service hours for each service was calculated monthly for each of the 24 months of study. Dichotomous variables were used for gender, minority status, and education. Age was measured in 10 year intervals. The structured Clinical Interview for DSM IV was administered at two sites while case records by treating psychiatrist were used at the other sites. Level of functioning was self rated. Receipt of public assistance was reported by the subjects. An evaluation of the Employment Intervention Demonstration Program's protocol found good to excellent validity and reliability on these measures. Of the 1,273 participants, 65% completed five interviews. Those participants were compared to others regarding model covariates. The only significant differences were gender and age. After calculation and inspection of frequency distributions and zero order relationships, outcome were visually inspected. Then random-effects logistic regression modeling, was used to address hypotheses at the multivariate level. All models included: demographics, clinical factors, time and study site.
