Dual-earner couples now work significantly more hours than in the past, but few couple-level studies examine whether work hours are linked to mental health and quality-of-life outcomes. In 2001, Jacobs and Gerson proposed that combined spouse work hours would better predict outcomes than would spouses’ individual work hours. Longitudinal data from a random sample of 211 dual-earner couples with children partially support this hypothesis. Our findings suggest that future research on dual-earner couples’ work hours should be couple-level and longitudinal, estimate both linear and non-linear relationships, and include multiple positive and negative outcomes as well as subjective indicators of the meaning of work hours.
