title: The role of parental motivation in family-based treatment for childhood obesity.
abstract: This study investigated the role of parental motivation (importance, confidence and readiness) for predicting dropout and outcome from family-based behavioral treatment for childhood obesity. Parent and child demographics, adherence to treatment, and weight loss parameters were also explored as potential predictors. Eighty-four obese children (BMI-standard deviation scores (SDS) >2.14) and a participating parent with each child started treatment consisting of 12 weeks of group and individual treatment sessions (24 sessions total) delivered over a period of 18 weeks. Sixty-one families (73%) completed treatment and attended follow-up at 1 year after treatment. Child session attendance and completion of self-monitoring records served as measures of adherence. In regression analyses, parent reports (pretreatment) of confidence for doing well in treatment was the strongest predictor of treatment completion (P = 0.003) as well as early treatment response (weight loss at week 5) (P = 0.003). This variable remained a significant predictor of child weight loss at post-treatment (P = 0.014), but was not associated with child outcome at 1-year follow-up (P > 0.05). The only significant predictor of child weight loss at that point was child baseline weight (P = 0.001). However, pretreatment parent ratings of importance of and readiness for treatment did not predict dropout or weight loss at any point. The results underscore the importance of addressing parental motivation, specifically parental confidence for changing lifestyle related behaviors, early in the treatment process. Doing so may reduce treatment dropout and enhance treatment outcome.
