The purpose of this study is to evaluate the role of different parenting skills and parenting styles in the success of children enrolled in a family-based behavioral weight control program and to compare these skills and styles to those used by families with normal weight children.

Pediatric overweight has nearly tripled in the past several decades and while family-based behavioral weight control programs are the mainstay of treatment, there is considerable variability in their outcomes. Parents play an important role in the success of their children, particularly by implementing new behavioral skills. However recent evidence has also suggested that parenting style, or the way a parent interacts with their child and provides emotional support and discipline, may be another key element in pediatric weight control. Our goal is to evaluate the role of specific parenting (behavioral) skills and parenting style in the success of children enrolled in a standard family-based behavioral weight control intervention. Our goal is to examine whether specific parenting (behavioral) skills and parenting style change during the intervention and whether or not this change is related to changes in the child's BMI z-score.
