Objective: This study aims at identifying predictors of generic health-related quality of life (HRQoL) in chronically ill children and adolescents over time. The newly developed computer-adaptive test Kids-CAT was used to assess five dimensions of HRQoL. Methods: Longitudinal data from the Kids-CAT study on children and adolescents with asthma, diabetes and juvenile arthritis (n = 248; aged 7–17 years) were assessed at three measurement points over six months. Individual growth modeling served to investigate effects of sociodemographic, disease- and health-related as well as psychosocial factors on HRQoL dimensions Physical Well-Being (WB), Psychological WB, Parent Relations, Social Support & Peers, and School WB over time. Results: Besides effects of sociodemographic variables on HRQoL dimensions Social Support & Peers as well as School WB, we found that a longer duration of the disease was associated with better Physical WB. Lower scores were found for patients with juvenile arthritis compared to those with diabetes in HRQoL dimensions Physical WB and Social Support & Peers. Disease control was positively related to Physical and Psychological WB over time. Mental health problems were negatively associated with four, and subjective health complaints with all five HRQoL dimensions over time. Parental mental health was positively related to the patients' HRQoL score in Parent Relations over time. Conclusions: HRQoL as a multidimensional construct is associated with a wide range of different factors. Pediatricians should consider potential mental health problems and subjective health complaints in their patients. Finally, parental HRQoL can affect HRQoL in chronically ill children and adolescents.
