Employment outcomes were aggregated by computing the total number of jobs, hours worked, and wages earned over the entire follow-up period. Potential interactions between site, treatment group, and work were evaluated by performing an analysis of variance (ANOVA), with site and treatment group (supported employment with cognitive training or supported employment alone) as the independent variables and the total number of jobs worked as the dependent variable. A chi-square analysis was conducted to compare the two treatment groups on percentage of patients who obtained work over the course of the follow-up period. Additional analysis was also done to address a variety of data factors.

Comprehensive employment data were collected the first year. Cognitive and psychological assessments were administered at baseline and three months later.
Diagnostic and background information were retrieved from the participants charts, interviews, and staff reports. Employment outcomes were measured through contact with the participants and staff. Seven different tests were used to measure cognitive functions (i.e.. attention and concentration, psychomotor speed, information processing speed, verbal learning and memory, executive functioning and overall cognitive functioning) at baseline and 3 month follow up.
Psychiatric symptoms were measured with interviews using the Positive and Negative Syndrome Scale. Efforts were made to get follow up employment data for the one year following randomization. Intent to treat analyses of the employment outcomes were conducted on the entire randomized sample that had some follow up data (n=44). The statistical analysis included: x2, t test and analyses of covariance. Due to skewed data Mann Whitney U tests were also used.

The intervention group was enrolled between 1999 and 2002, while data collection continued until 2004. Data were obtained from Threshold PsychServe system and were measured in terms of hours of support. Clients were also completed a survey, which included demographics, as well as a self-report of number of weeks worked and number of years since last employment.

The Positive and Negative Syndrome Scale was administered, as well as the number of lifetime hospitalizations and diagnosis (using DSM-IV). These were collected at baseline.

Data were analyzed using SPSS 11.0 for Windows and Hierarchical Linear Modeling. Zeroes were recorded for participants' IPS contacts for quarters when they dropped IPS.

Hypotheses were tested by totaling variables across the entire study and conducting hierarchical linear modeling regressions, as well as examining the data longitudinally by using the hierarchical linear model.

An ACCEPT intake form provided a profile of the trainees. The Lancashire Quality of Life Profile was used to obtain information on perceived quality of life. A Goal Attainment Form documented the trainees top five goals or objectives. Participant views about ACCEPT quality of services was gained using an Client Evaluation Form. A Stakeholder Questionnaire was also used. T-Tests were used to examine pre and post training differences in the mean LSS scores.

Various scales were used to measure improvements specifically related to the cognitive ability that was being treated (i.e.. attention deficits, memory problems, executive deficits) in each of the 3 case studies.

The Exhaustive Chi-Square Automatic Interaction Detector (CHAID) data mining technique was used. The technique requires the use of categorical values; therefore, age and education (continuous variables) were recoded into categories. Decision trees "were used to generate rules for the classification of this dataset" (p. 360). SPSS AnswerTree 2.0 statistical software was used for the data analysis.

Abacus program records were reviewed to identify individuals served during the established time frame. Then rates of successful employment and trends were identified. To ensure confidentiality each participant was randomly assigned a number during data analysis. General demographics was collect from records. Records were reviewed by the primary investigator and a graduate student. Other data collected from the file review related to employment outcomes and whether or not ongoing support was accessed. Reliability was checked using cross referencing and strengthened by having the student randomly code one fourth of the data which was compared to the primary investigators coding. Coded data was entered into the Statistical Package for the Social Sciences 15.0. The package calculated statistics that were used to develop and describe program employment outcomes.

A semi-structured interview was developed, which included open-ended questions. Open-ended questions were transferred into structured ratings

Treatment effect of OT was tested using the t test for continuous measures and the chi-squared test for categorical variables. For longitudinal analysis, the generalized estimating equations method for dichotomous outcomes and a generalized linear model approach for continuous outcomes was used.

The study questionnaire included the following measures. The Empowerment Among Users of Mental Health Services Scale; the Herth Hope Index, Perceived obstacles to work; and behaviours indicating nearness to the labour market. This questionnaire was usually completed during an approximately one hour face to face interview. The first was completed at baseline and another at follow up (12 months later).Statistically significant differences were tested. Analysis of variance was also used. SPSS 15.0 was used to analyze all data.
