Effectiveness of a 10-week Multicomponent Intervention Combined With Parent Education on Binge Eating Behavior in Children and Adolescents

The study will be conducted by the research team in close collaboration with the organization behind the multicomponent camps and their staff (Julemærkefonden/Julemærkehjem Hobro and Fjordmark). The multicomponent camps are well-established non-governmental institutions focusing on improving health and well-being in 7-14-year-old children by providing a structured environment, including social and physical activities, healthy meals and daily physical activities. Children of all weight classes can be referred to attend the camps by their general practitioner due to overweight, obesity and/or psychological challenges e.g., loneliness, bullying and family-related challenges. All 7-14-year-olds attend the camp free of charge.

In the present study, all participants will receive standard care during the 10-weeks at the multicomponent camp, which follows national recommendations concerning diet and physical activity. All participants will be screened for BED with the STOB screening tool before the intervention. Among those participants who screen positive for BED with the STOB screening tool, parents/guardians will be randomized to receive either:

Standard parental involvement during the camp (P-ST).

or

A parental BED intervention in addition to the standard parental involvement during the camp (P-BED)

In all cases where BED is suspected at recruitment based on the STOB screening tool, participants will be referred to a diagnostic interview (The Child Eating Disorder Examination (ChEDE)) to determine if participants fulfill the diagnostic criteria for BED. The use of ChEDE at baseline and after the intervention is implemented to validate the STOB screening-tool for future use. Therefore, a subsample of participants screened negative at recruitment with the STOB screening-tool (i.e., no BE behavior) will also undergo a diagnostic interview.

Throughout the study, interviews will be conducted with a subsample of participants, parents, and camp staff. Participants and camp staff will be interviewed to gain insights into their perspectives of using the STOB screening-tool. Moreover, parents will be interviewed to include their perspectives in the developmental process and to gain insights into their interpretation of the content, format, and perceived value of the parental BED intervention.
