Acceptance Based Behavioral Intervention for Weight Loss: A Randomized Trial
Descripción general del estudio

Descripción detallada
Obesity is a major health problem and behavioral weight control programs are the treatment of choice for mild and moderate obesity. However, there is marked variability among participants in the weight losses achieved in these programs and the maximum weight losses are typically achieved at month 6, followed by weight regain. Thus innovative approaches are needed to improve longer-term treatment outcomes.
Currently, the same behavioral treatment program is offered to all participants, with no tailoring to meet the needs of specific subgroups. One subgroup that may need a specialized approach are those who report high levels of internal disinhibition, i.e. eating in response to negative thoughts or emotions. Over 50% of individuals entering behavioral weight loss programs report high levels of internal disinhibition on the Eating Inventory (EI), this subgroup is distinct from those with binge eating disorder, and most importantly, these individuals lose significantly less weight than other participants during weight loss treatment [particularly at 18 months]. Thus efforts are needed to develop more effective treatments for this subgroup. The proposed research is significant because it may help move the field from a "one size fits all" approach, to the development of interventions for specific subgroups of the population.
The investigators hypothesize that individuals who report problems with internal disinhibition may achieve better weight losses in an enhanced behavioral weight loss program that focuses on acceptance-based strategies. Whereas standard behavioral treatments teach patients to control their negative thoughts with techniques such as cognitive restructuring and distraction, acceptance based strategies teach patients to experience thoughts and feelings as they are, without attempting to control them and to continue to pursue their behavioral goals despite experiencing negative thoughts and feelings. Acceptance-based strategies have been shown to be helpful for a number of behavioral problems including weight loss and maintenance, however are yet untested in large trials.
The current study is a randomized controlled trial comparing standard behavioral weight loss treatment with a program which incorporates acceptance based strategies in the treatment of overweight/obese individuals with problems with internal disinhibition. A total of 160 participants will be randomly assigned to a standard behavioral weight loss treatment program (SBT) or to an innovative approach that combines standard behavioral weight loss with acceptance based strategies (referred to hereafter as "Acceptance Based Behavioral Intervention" or ABBI). Both groups will meet weekly for 6 months, biweekly for 3 months and then monthly for 3 months. Assessments will be conducted at baseline and 6 month intervals for 24 months total, with measures of weight, acceptance of negative emotions, distress tolerance, and adherence to the weight loss program.
The primary hypothesis is that participants in the ABBI program will achieve greater changes in weight (in the form of weight reductions) at 6, 12, 18, and 24 months when compared to baseline weight than participants in SBT. Secondary hypotheses are that participants in ABBI will experience greater improvements in acceptance of weight related negative thoughts and emotions and distress tolerance and better treatment adherence than participants in SBT.
