The aim of this study was to investigate the link between parenting and parents' perspectives on health-related decision making for adolescents. During adolescence, there is a gradual increase in responsibility and autonomy, which influences parenting behavior and child development. Understanding how parenting is associated with parents' views on medical decision making is crucial in the context of the parent-child-physician triad. This study was the first to explore parenting and parents' views on adolescent health care decision making. We compare Belgian and Dutch parents-two countries selected for their different legal frameworks on medical adolescent decision making.
