The present study tests the utility of the Social Cognitive Model of Well-Being (SCWB) in the context of work, with a sample of 348 women engineers. Using structural equation modeling, we examined the relations of positive affect, self-efficacy, work conditions, goal progress, and environmental supports and barriers that were assumed to account for job satisfaction and life satisfaction of women engineers. Overall, the model provided a good fit to the data, and SCWB predictors accounted for a significant amount of variance in job satisfaction (63%) and life satisfaction (54%) with our sample of women engineers. As expected, most paths of the SCWB model were significant; however, we also found nonsignificant relations among variables in the model. In particular, goal progress did not play a critical role in the present study. In addition, we examined the indirect effects of environmental variables (e.g., supports and barriers) on job satisfaction via sociocognitive variables (e.g., self-efficacy and perceived work conditions) in the engineering work domain. Implications for practice, theory, and future vocational and organizational research in engineering are discussed.
