What family dimensions are important for health-related quality of life in adolescence?

Abstract

Adolescence is a relevant life stage in which to study a global well-being measure, health-related quality of life, in order to analyse the impact of important determinants in adolescents' health-related quality of life (e.g., the quality of family relationships). This study aimed to examine the impact of several family dimensions (parental affection, parental promotion of autonomy, family activities, adolescent disclosure, parental solicitation and parental knowledge) on adolescents' health-related quality of life. Additionally, this study investigated whether demographic variables (adolescents' gender and age) influenced health-related quality of life and moderated the relationship between family dimensions and health-related quality of life. The sample was composed of 14,825 adolescents, aged 13–14, 15–16, and 17–18, from the 2006 edition of Spain's Health Behaviour in School-aged Children study. The results showed that parental promotion of autonomy, family activities and especially parental affection were the most important dimensions influencing health-related quality of life. Boys reported higher health-related quality of life than girls, and younger adolescents reported higher health-related quality of life than older adolescents. The discussion explains how the aforementioned family dimensions encourage better health-related quality of life in adolescents.
