Three questions stimulated by Erik Erikson's theory of generativity were addressed: 1) Is generativity associated with greater subjective well-being? 2) Are agency and communion additive or interactive predictors of generativity? 3) Does generativity play a distinct role during the midlife period? Among ninety-eight midlife adults, generativity was positively related to positive affectivity, satisfaction with life, and work satisfaction. Generativity was independently predicted by agentic (masculine) and communal (feminine) traits. Among fifty-eight young adults, generativity predicted positive affect at home. Generativity was independently predicted by agentic (power) and communal (love) interpersonal orientations. Using event-contingent recording of agentic and communal behavior at work, agency was a stronger predictor of generativity for young adult men, and communion was a stronger predictor for young adult women. The studies demonstrate that generativity has similar relations to agency and communion in young and midlife adults; however, generativity may be a stronger predictor of subjective well-being in midlife adults.
