Primary Outcome: Weight
weight loss
Participants weighed themselves in pounds or kilograms and sent in an image of their scale to report their weight at baseline, after intervention, and at follow-up. Postoperative percentage total weight loss was calculated using the following formula: percentage total weight loss = ([baseline weight in kilograms − postintervention or follow-up weight in kilograms]/baseline weight in kilograms) × 100. Weight outcomes were calculated using participant-reported weight at baseline rather than presurgery weight to determine whether the tele-CBT intervention was efficacious in affecting weight outcomes and to eliminate the surgery itself as a factor for weight loss.
