This study provides the first comprehensive review of literature examining proactive personality. The authors use career success as a broad organizing framework, meta-analyzing 313 correlations from 107 studies. Results indicate proactive personality is positively related to objective and subjective career success. Further, results indicate proactive personality relates to variables consistent with contest mobility (e.g., job performance) and sponsored mobility (e.g., taking charge/voice behavior) avenues to career success. Proactive personality's relationship with supervisor-rated overall job performance is particularly noteworthy in that it is stronger than that reported for any of the Big Five factors or the Big Five collectively. Proactive personality is positively related to a variety of employability-related variables (e.g., learning goal orientation, career self-efficacy), four Big Five trait factors (extraversion, openness to experience, conscientiousness, and neuroticism), but is unrelated to social desirability. The authors' literature review indicates only the original 17-item scale and 10-item scale tend to exhibit good internal consistency. (Contains 7 tables.)
