Abstract
This study explored the associations between family support and satisfaction with life, food-related life and family life. It also assessed the associations between both parents' work-life balance and satisfaction with life, food-related life and family life among adolescent children from dual-earner families. Questionnaires were administered to 303 dual-earner families with one child between 10 and 17 years in Temuco, Chile. Adolescents answered the Satisfaction with Life Scale (SWLS), Satisfaction with Food-related Life scale (SWFoL), Satisfaction with Family Life scale (SWFaL) and the Family subscale of the Multidimensional Scale of Perceived Social Support. Both parents answered the Work-life Balance (WLB) scale. Using structural equation modelling and having controlled for adolescents' gender, age and socioeconomic status, we confirmed that adolescent life satisfaction is associated with satisfaction with family life and food-related life. Food-related life satisfaction and family life satisfaction had complete mediating roles between perceived family support and adolescents' life satisfaction. Satisfaction with food-related life also had a complete mediating role between both parents' WLB and adolescents' life satisfaction. Satisfaction with family life had a complete mediating role between mothers' WLB and adolescents' life satisfaction. In addition, mothers' WLB was positively associated with perceived family support among adolescents. These findings suggest the need to improve family support and work-life balance among mothers in order to enhance adolescents' satisfaction with different domains of life in dual-earner families.
