Dyadic effects of work overcommitment on depression in dual-earner couples: based on the actor–partner interdependence model

Abstract

ABSTRACT In this study, we aimed to examine the actor and partner effects of overcommitment on depression in dual-earner couples and the potential mediating role of emotional exhaustion at the actor and partner levels. With a cross-sectional design, 172 dual-earner couples in Chongqing, China, completed the measures of overcommitment, emotional exhaustion, and depression. The results showed that (a) overcommitment has a significant actor effect on depression for the husband and wife, and there were gender differences in the partner effects; that is, a wife’s overcommitment has a significant partner effect on the husband’s depression, while a husband’s partner effect was not significant; (b) emotional exhaustion mediated the effects of overcommitment on depression for both husbands and wives at the actor level, while at the partner level, only a wife’s exhaustion mediated the partner effect of a wife’s overcommitment on a husband’s depression. Focusing on couples’ interdependence, these results enriched the understanding of the relationship between overcommitment and depression within dual-earner couples.
