What is the relationship between the quality of men's job and partnership roles on the one hand and men's mental health on the other? This question was addressed in a random sample of 300 men, ages 25-40, in dual-earner couples. Predictions were made from both main-effects and two interaction-effects models of this relationship. More specifically, negative-spillover effects, as predicted by the role-stress model, were estimated both from work to home and home to work. Positive-spillover effects, as predicted by the role-enhancement model, were estimated from home to work and from work to home. The general finding was that the effects are additive not interactive, thus supporting the main-effects model. With respect to spillover effects, there was some support for the role-stress model, but no support for the role-enhancement model. More specifically, the relationship between job stress and psychological distress was exacerbated among men who had troubled relationships with their partners.
