An emotion regulation training in the treatment of obesity in young adolescents: The protocol of a Randomized Controlled Trial

Abstract Background: The prevalence rates of childhood obesity are increasing. The current multidisciplinary treatments for (childhood) obesity are effective, but only short term and rather moderately. A possible mechanism to explain the onset and maintenance of childhood obesity is a maladaptive way of regulating high levels of stress and emotions. Therefore, the current RCT-study aims to test the effectiveness of adding an emotion regulation training to care as usual (multidisciplinary obesity treatment) in young inpatients (10-14) involved in an obesity treatment program compared to care as usual alone. The research model for this RCT-study states that when high levels of stress are regulated in a maladaptive way, this can contribute to the development of obesity. Method: The current study will recruit 140 youngsters (10-14 years) that are involved in an inpatient multidisciplinary obesity treatment (MOT) program. After giving consent to participate in the study, youngsters will be randomly assigned, during consecutive waves, to one of two conditions: care as usual (receiving MOT) or intervention (receiving MOT and on top an emotion regulation training). The training itself consists of 12 weekly sessions, followed by a booster session after three and five months. The participants will be tested pre, post and at 6 months’ follow-up. We hypothesize that, compared to the control condition, youngsters in the intervention condition will (1) use more adaptive emotion regulation strategies and (2) report less emotional eating, both primary outcome measures. Moreover, on the level of secondary outcome measures, we hypothesize that youngsters in the intervention condition, compared with the control condition, will (3) report a better sleep quality, (4) undergo an improved weight-loss and weight-loss maintenance and (5) experience a better long-term (6-months) psychological well-being. Discussion: This study will add to both the scientific and clinical literature on the role of emotion regulation in the development and maintenance of different psychopathologies, as emotion regulation is a transdiagnostic factor.
