This study explored the spillover and crossover associations between satisfaction with food-related life and life satisfaction in mothers, fathers and adolescent children in dual-earned families. This is a cross-sectional design study with mothers, fathers and children surveyed in Temuco, Chile. The participants were 303 dual-earner parents and their adolescent children (mean age 13.3 years, 51.5% female). Actor-partner Interdependence Model (APIM) and structural equation modeling were used to explore spillover (actor effect) and crossover (partner effect) associations among family members. As a result, fathers' satisfaction with food-related life was positively associated with their own life satisfaction (p ≤ 0.01), as well as with their partner's (mother's) satisfaction with life (p ≤ 0.05), but not with their adolescent child's life satisfaction (p > 0.1). Mothers and children presented positive spillovers between their own levels of satisfaction with food-related life and life satisfaction (p ≤ 0.01). No crossover effects were found between mothers and children (p > 0.1). This study results underscore the positive association between satisfaction with food-related life and life satisfaction among members of dual-earner families with adolescent children. Special efforts should be made by dual-earner parents to improve the variables related to their satisfaction with food-related life as well as their children's satisfaction.
