The primary purpose of this exploratory research was to examine whether self-efficacy would be predictive of future vocational outcomes for participants in a supported employment program. Participants were 86 persons associated with a private, non-profit agency located in Baltimore, Maryland, which provides supported employment services for persons with psychiatric disabilities. Stepwise logistic regression analyses supported the hypothesized relation between self-efficacy and whether the employment goal was attained. Hypothesized relations between symptomatology and prior employment history and the outcome variable were also supported. The importance of this research is that it lends support to self-efficacy as a promising predictor of vocational rehabilitation outcomes.
