Telephone Delivered Weight Loss, Nutrition, Exercise WeLNES Study
Study Details
Study Description
Brief Summary
This phase III trial compares telephone delivered Acceptance and Commitment Therapy to standard behavioral therapy for improving weight loss in overweight or obese participants. Acceptance and Commitment Therapy focuses on increasing willingness to experience physical cravings, emotions, and thoughts while making values-guided committed behavior changes. Acceptance and Commitment Therapy may work better at improving weight loss compared to standard behavioral therapy.

Detailed Description
OUTLINE: Participants are randomized to 1 of 2 arms.
ARM I: Participants receive ACT telephone coaching over the course of 12 months, calls 1-16 weekly, calls 17-23 biweekly, and calls 24-25 monthly. Call 1 is 30 minutes in duration, while calls 2-25 are each 15-20 minutes in duration.
ARM II: Participants receive SBT telephone coaching over the course of 12 months, calls 1-16 weekly, calls 17-23 biweekly, and calls 24-25 monthly. Call 1 is 30 minutes in duration, while calls 2-25 are each 15-20 minutes in duration.
Participants are followed up at 6, 12, and 24 months after randomization.

Outcome Measures
Primary Outcome Measures
- 10% or more weight loss [At 12 months after randomization]
Will be measured remotely by cellular-enabled scales. Will compare the two telephone interventions, using logistic regression.
Secondary Outcome Measures
- Percent weight change [At 6, 12, and 24-months post randomization]
Will be measured remotely by cellular-enabled scales.
- Dietary intake [At 6, 12, and 24-months post randomization]
Will be measured with the Fitbit smartphone app food logging feature.
- Physical activity [At 6, 12, and 24-months post randomization]
Will be measured with the Fitbit Inspire mailed to participants.
- Trajectories of weight change [At 6, 12, and 24-months post randomization]
Will compare between the two arms, with time as the independent variable using mixed effects modeling with linear, quadratic, and cubic effects of time.
