Abstract
Mindfulness research is growing within organizational studies. Emerging evidence across many fields demonstrates that mindfulness is related to numerous individuals' outcomes in the workplace, but this knowledge base has not been investigated enough. This study extends previous literature by examining the extent to which trait mindfulness influences individuals' job performance and career success. Also, this study investigates the interactive effects of trait mindfulness and proactive personality on job performance and career success. The sample of the study included three hundred subjects with at least of three years of work experience in the United States of America. Hypotheses were tested using multiple linear regression. The results supported the hypotheses that trait mindfulness would be positively associated with both job performance and career success, measured by career satisfaction. Interestingly, trait mindfulness moderated the relationship between proactive personality and both job performance and career satisfaction such that high trait mindfulness substitutes the positive influence of proactive personality. Practical implications, possible limitations, and future research directions are briefly discussed.
