Results are reported from a 2 1/2 year follow-up of respondents who participated in a randomized field experiment that included the Jobs Program, a preventive intervention for unemployed persons. The intervention was intended to prevent poor mental health and loss of motivation to seek reemployment and to promote high-quality reemployment. The results of the long-term follow-up were consistent with those found 1 and 4 months after intervention (Caplan, Vinokur, Price, & van Ryn, 1989). The results demonstrate the continued beneficial effects of the intervention on monthly earnings, level of employment, and episodes of employer and job changes. These findings are supported by a benefit-cost analysis, which demonstrates large net benefits of the intervention to the participants and to the federal and state government programs that supported the project.
