Response to Vorland et al's Letter to the Editor about 'Impact of motivational interviewing on outcomes of an adolescent obesity treatment: Results from the MI Values randomized controlled pilot trial'

摘要

We thank Vorland et al for their careful review of our study and appreciate the opportunity to respond. We also appreciate their ongoing efforts to enhance scientific reporting in obesity trials, advancing science in this critical public health area. We reported on the primary outcomes of the MI Values trial, a randomized controlled pilot trial investigating if motivational interviewing (MI), implemented adjunctive to an obesity treatment, led to differential dietary intake, physical activity and body mass index (BMI) z-scores, among predominately African American adolescents with obesity. In MI Values, adolescents were randomized to either two MI sessions or to an education control, matched on contact time. All adolescents participated in an empirically supported behavioural weight management treatment. The primary findings were that there were no between-group differences in physical activity (self-reported) or BMI z-score, and that at 3-month follow-up, self-reported energy intake was lower in the MI group.
