Note. Of 106 participants in the longitudinal US community sample, 94 provided follow-up data. In that sample, data for gender and age is missing for one participant. BMI and RED-9 are reported for both baseline and 6 months later. Of 165 participants in Canadian University sample, 51 completed the laboratory-based eating behavior assessment (chips consumed). Age in years; BMI = body mass index; RED-9 = Reward-based Eating Drive Scale, 9 item; CoEQ = Control over Eating Questionnaire; chips assessed in grams.
