Allocation: | Randomized |
Intervention Model: | Crossover Assignment |
Intervention Model Description: | After two years of intervention arm study, the usual care arm will receive MI training. |
Masking: | None (Open Label) |
Primary Purpose: | Treatment |
Official Title: | Population Effects of Motivational Interviewing on Pediatric Obesity in Primary Care |

Arm | Intervention/treatment |
---|---|
Active Comparator: Usual Care
At the end of the intervention period, 1-2 pediatric clinicians will be offered the in-person MI training and DVD materials |
Behavioral: Usual Care
PCPs provide care as normal |
Experimental: Intervention by Clinicians
Dietitians will provide up to 6 telephone counseling sessions. •Parents will complete surveys after enrollment and at the end of intervention |
Behavioral: Intervention by Clinicians
PCPs deliver 4 sessions of MI in person, and RDs deliver 6 sessions of MI via telephone. PCPs and RDs will receive 2 days of MI training.

- Percent distance from the sex-age-specific 95th percentile, on both the linear and log-transform scales. [ Time Frame: Approximately 2 years from baseline ]Recent changes to the evaluation of interventions on body mass index (BMI) necessitates an update to evaluating intervention effects on BMI in children with obesity and overweight in this trial. This research will investigate change in adiposity defined as BMI percent distance from the sex-age-specific 95% percentile, on both the linear scale (for interpretable effect measures) and log-transform scales (to meet required model/distribution assumptions). We will report the analysis results using both measures, one as the primary analysis and the other the sensitivity analysis.
- Effectiveness among patients of study clinicians trained in MI and whose parents engage in the intervention (per-protocol analysis) [ Time Frame: Approximately 2 years from baseline ]Although the primary intention to treat analyses described above for primary outcome will include all patients assigned to groups regardless of intervention exposure, as a secondary analysis, we will examine effects among the subsample of children who parents actively participated in the intervention, defined as receipt of at least 50% of the planned MI dose. The same modeling approaches discussed above will be employed to test this secondary aim.
- Population level effects: Effects on all youth of participating providers [ Time Frame: Approximately 2 years from baseline ]To assess the effect of the intervention at the population level, using a similar analytic approach used in AIM I, we will include data from all age-eligible children of all participating practitioners will be included in the analysis, even if the child was not enrolled in the study.
