How did it work? An examination of the mechanisms through which an intervention for the unemployed promoted job-search behavior.

Conducted process analysis of treatment mediation effects (Judd & Kenney, 1981) on longitudinal data from a large randomized field experiment with 928 recently unemployed persons. The experimental treatment included an intervention that succeeded in promoting quality reemployment outcomes, as described in earlier reports (Caplan et al., 1989; Vinokur et al., 1991). Using Ajzen's theory of planned behavior (Ajzen, 1985, 1988), the analyses examined the mediating effects of job-search self-efficacy, attitude, norms, and intention on job-search behavior. The results provided substantial support for the theory of planned behavior and demonstrated the mediational role of job-search self-efficacy. For both 1- and 4-month posttests, job-search self-efficacy was shown to mediate the effects of the intervention through its direct effects on job-search intention and on short term job-search behavior, as well as through its indirect effects on subjective norms and attitude. However, in the longer term 4-month posttest, exposure to the intervention had a direct effect on job-search behavior. This long-term direct effect of the intervention was hypothesized to reflect the influence of inoculation against setbacks which is essential for sustaining the long-term behavioral efforts involved in job seeking.
