Previous research showed that job stressors are positively related to proactive work behavior. This study examines if these relations can be generalized to supervisor-rated proactive behavior and if relations of job stressors (time pressure, situational constraints) and job control with proactive behavior can be explained by role breadth self-efficacy as an underlying mechanism. We used supervisor ratings of proactive behavior (personal initiative, taking charge) from 140 employees working in small and medium-sized companies. Multilevel path analyses supported a partial mediation model. Job control and time pressure were positively related to role breadth self-efficacy, and role breadth self-efficacy was positively related to proactive behavior. Job control had also a direct relation with proactive behavior. The relation between situational constraints and proactive behavior was not significant.
