In this study, we further explored whether any of the dimensions in the five-factor model of personality (i.e., openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism) were related to facets of workaholism (i.e., work involvement, work drive, and work enjoyment) in a sample of American workers in various occupational settings. Results showed that personality factors explained a significant amount of the variance for each workaholism facet, above and beyond personal demographics. Conscientiousness and agreeableness were positively related to work involvement, while conscientiousness and openness to experience were positively related to work drive. Agreeableness, conscientiousness, and openness to experience were positively related to work enjoyment, while neuroticism was negatively related to work enjoyment. By identifying personality factors related to workaholism, employers can better predict workaholic tendencies during recruitment and selection. (Contains 2 tables.)
