The Multidimensional Workaholism Scale in a Korean Population: A Cross-Cultural Validation Study

This study aimed to provide a reliable and valid measure of workaholism for Korean workers. We translated the Multidimensional Workaholism Scale (MWS) into Korean and validated it with a sample of 1020 full-time Korean employees. An exploratory factor analysis revealed a four-factor solution (Study 1; N = 524), and a confirmatory analysis further demonstrated good model fit of the four-factor structure (Study 2; N = 496). The scale’s concurrent and construct validity was supported by positive correlations with other existing measures of workaholism, emotional exhaustion, and work–family conflict (WFC) and by a negative correlation with psychological detachment. Moreover, the MWS demonstrated a moderate association with work engagement, but no significant association with job satisfaction. It further showed significant incremental validity in predicting emotional exhaustion and WFC. The findings support the Korean MWS version’s reliability and validity for measuring workaholism among Korean employees. Theoretical implications for the workaholism literature and practical implications for corporate counselors and human resource practitioners are discussed.
