Transition from pediatric to adult health care is a key milestone for children and young people (CYP) with chronic conditions. Family management (FM) and self-management are two important concepts during the process. This study aimed to explore the relationships between FM, self-management and transition readiness, and quality of life (QoL), and identify the potential CYP or family factors influencing the relationships. Data about FM, self-management and transition readiness, QoL, and various contextual factors were collected from 268 caregiver-child pairs.
