Pilot Trial of a Telephone Weight Loss, Nutrition, Exercise Study

Status Completed

Clinical Trial Summary

Many behavioral weight loss interventions have been developed, but still have significant limitations in terms of achieving clinically significant, sustained weight loss. A recent study incorporating Acceptance and Commitment Therapy (ACT) in a randomized clinical trial resulted in participants who attained significantly greater 12-month weight loss in the ACT arm than those assigned to standard behavioral treatment, suggesting that ACT may have the potential to improve behavioral weight loss outcomes. The investigators have developed a novel telephone-delivered version of the ACT behavioral weight loss intervention, based on proven success using ACT telephone counseling intervention for smoking cessation.

Clinical Trial Description

There is consistent evidence from observational studies that higher amounts of body fat are associated with increased risks of cancer. Many behavioral weight loss interventions have been developed, but still have significant limitations in terms of achieving clinically significant, sustained weight loss. A recent study incorporating Acceptance and Commitment Therapy (ACT) in a randomized clinical trial resulted in participants who attained significantly greater 12-month weight loss in the ACT arm than those assigned to standard behavioral treatment, suggesting that ACT may have the potential to improve behavioral weight loss outcomes. However, this study required in-person clinic visits with treatment groups, which limits its potential reach and disseminability. The investigators have developed a novel telephone-delivered version of the ACT behavioral weight loss intervention, based on our proven success using ACT telephone counseling intervention for smoking cessation. There will be a two-arm pilot randomized trial (N = 100), comparing the ACT telephone intervention to a standard behavioral treatment (SBT) telephone control. The pilot RCT will yield engagement, receptivity, and preliminary weight loss results that will provide critical and timely weight loss intervention data. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
