Cognitive theories of adherence to difficult courses of action and findings from previous survey research on coping with a major life event—job loss—were used to generate a preventive intervention, tested by a randomized field experiment. The aim was to prevent poor mental health and loss of motivation to seek reemployment among those who continued to be unemployed and to promote high-quality reemployment. Ss were 928 recently unemployed adults from southeastern Michigan, representing a broad range of demographic characteristics; they were randomly assigned to either the experimental or control condition. The experimental intervention included training in job seeking with a problem-solving process emphasizing inoculation against setbacks and positive social reinforcement. A pretest was administered, followed by posttests 1 and 4 months after the experiment. The experimental condition yielded higher quality reemployment in terms of earnings and job satisfaction, and higher motivation among those who continued to be unemployed.
