The objective of this study is to investigate the effi cacy of a preventive cognitive-behavioral group intervention for children with chronic illnesses, and to test the eff ect of an added parent component. METHODS Children (n = 194) and their parents participated in a multicenter randomized clinical trial comparing a child-only intervention and a parent-child intervention to a wait-list control group. Primary outcomes were parentand self-reported internalizing and externalizing problems; secondary outcomes were child disease-related coping skills (information seeking, relaxation, social competence, medical compliance, and positive thinking). Assessments took place at baseline, and at 6-month and 12-month follow-ups. Intention-to-treat mixed-model analyses were performed to test the diff erence in change in outcomes. RESULTS The intervention had a positive eff ect on changes in parent-reported internalizing problems, child-reported externalizing problems, information seeking, social competence, and positive thinking. The additional eff ect of parental involvement was observed on parent-reported internalizing problems, child-reported externalizing problems, information seeking, and social competence. Illness severity and illness type did not moderate the eff ects. Of the families in the wait-list control group, 74% sought alternative psychological support during the intervention period. CONCLUSION This RCT supports the effi cacy of a protocol-based group intervention for children with chronic illnesses and their parents. Adding a parental component to the intervention contributed to the persistence of the eff ects. Future research should focus on moderating and mediating eff ects of the intervention.
