Randomized Controlled Comparison of Two Cognitive Behavioral Therapies for Obese Children: Mother versus Mother-Child Cognitive Behavioral Therapy

BACKGROUND: Parent-child treatments have been shown to be superior to child-focused treatments of childhood obesity. Yet until now, the comparative effectiveness of parent-only and parent-child approaches has been little studied. METHOD: Fifty-six obese children and their families were randomly assigned to a 16-session cognitive behavioral therapy (CBT) for the parents only or for a combined treatment of parents and children. Children's percent overweight, the body mass index of their mothers, and behavioral and psychological problems of children and mothers were assessed. RESULTS: Both treatments reduced children's percent overweight significantly and equally by 6-month follow-up. Also both treatments provided similar results in reducing general behavior problems (externalizing and internalizing behavior problems), global and social anxiety, and depression. CONCLUSIONS: Our results point to a comparable efficacy of the two treatments. Further, psychological well-being of both mothers and children can be improved in a CBT for obese children and their parents. Future studies should focus on finding ways to improve the adherence of families to long-term treatment of obesity in childhood
