Acceptance-based Care for Child Eating and Physical Activity Treatment

Pilot Treatment Group. Children and caregivers who meet preliminary eligibility via phone
screening will be scheduled for a baseline visit within one month of the first treatment
session. During this visit, eligibility will be confirmed including height/weight
measurements to determine BMI and informed consent/assent procedures will be conducted. Pairs
providing informed consent/assent will complete questionnaires, measurements, and cognitive
testing. Pre- and post-evaluations are estimated to take less than 70 minutes to complete.
The assessments will be identical with the exception of online food/activity monitoring
training at pre-treatment only and program evaluation surveys at post-evaluation only. Each
treatment group will include a total of 8 child-caregiver pairs (total of 16 child-caregiver
dyads with groups combined). A total of 18 weekly treatment sessions will be held over 4.5
months for the ABBT protocol at a rate of 1 session per week. Semi-structured group
interviews will be incorporated into an extended treatment session at week 9 and week 18 to
assess caregiver and child experiences with the program.
