The More & Less Study: A Trial Testing Different Treatment Approaches to Obesity in Preschoolers

The More \& Less group will focus on how to use positive parenting practices (e.g., reinforcement/encouragement, limit setting, monitoring, problem-solving, positive involvement, and emotion regulation) instead of ineffective practices (e.g., coercive behavior, negative reciprocity, escalation, and negative reinforcement). Using a parent-group approach to intervention administration, each of the twelve More \& Less sessions (1.5h/wk) consist of introduction to effective parenting practices followed by a discussion and practice using role play and home practice assignments. The information and procedures will be tailored to focus on changes in the home environment, mostly related to child food habits and physical activity.

The treatment will be provided by local pediatricians in outpatient pediatric departments and will be based on lifestyle modifications, as recommended in the action plan for Stockholm County.
