This project will apply the concepts from the Chronic Care Model to the problem of pediatric obesity and proposes: 1) to assess the effectiveness of teaching primary care providers (in diverse practice settings) to use specific communication strategies with parents of overweight and obese children to help them take steps with their child toward healthy behavior change; 2) to offer core components of an efficacious evidence-based pediatric obesity treatment within the pediatric primary care setting to determine if participating children will achieve clinically meaningful weight loss (assessed as weight and BMI percentile changes at the end of treatment and at a six month follow-up); and 3) to assess the ability of trained, behavioral psychologists to offer the treatment so that desired child outcomes are achieved. The primary project outcomes will include: 1) increase in self-reported physician confidence in use of counseling skills related to pediatric overweight; and 2) change in child's diet, physical activity, weight and BMI percentile at the end of treatment and at 6-month follow-up.
