motivational interviewing in nourish for parents of overweight children

Conditions: Overweight and Obesity

Summary: the purpose of this study is to investigate if a brief, motivational interviewing intervention (nourish+mi) can improve retention and treatment adherence for parents enrolled in an intervention for their child's overweight (nourish+). the investigators hypothesize that children whose parents participate in nourish+mi will demonstrate lower attrition and greater adherence with nourish+, ultimately leading to greater treatment effects, compared with children whose parents are randomized to nourish+ or a control group.

there is an urgent need for innovative approaches to pediatric obesity prevention and treatment. there is also a demand for targeted strategies that reduce attrition and improve compliance with obesity treatment. intervening exclusively with parents of overweight children is a novel treatment approach, with demonstrated efficacy in reducing child body mass index (bmi) percentile. motivational interviewing (mi), a brief communication style for exploring and resolving ambivalence about change, may enhance treatment engagement when implemented as part of obesity interventions. further research investigating mi within pediatric obesity treatments is needed. in the current application, the investigators are examining whether mi implemented with parents for the treatment of their children's overweight can improve treatment effects. nourish+, a recently funded r01 (nourishing our understanding of role modeling to improve support and health; pi, mazzeo), is a culturally tailored parent intervention for overweight children ages 5-11. nourish+ targets lower-income, african american participants, a group at increased risk for pediatric overweight and associated complications, and builds on pilot work which yielded significant reductions in child bmi percentile. the investigators are adding an mi treatment into nourish+. specifically, we will randomly select 60 parents at enrollment and investigate if adding two brief mi sessions prior to the nourish+ group intervention will enhance treatment effects. the investigators will be able to compare nourish+mi with participants from the two r01 treatment conditions (nourish+ and control), matched on child ethnicity and gender. the investigators hypothesize that children whose parents participate in nourish+ mi will demonstrate lower attrition and greater compliance with nourish+, ultimately leading to greater treatment effects, compared with children whose parents are randomized to nourish+ or a control group.
