  Purpose
Bariatric surgery is the most effective treatment for patients with extreme obesity. Psychological interventions are not routinely offered in Bariatric Surgery Programs. Preliminary evidence suggests that Cognitive Behavioral Therapy (CBT) might be effective in reducing binge eating and improving surgical outcomes. The current study will examine whether the addition of telephone-based CBT (Tele-CBT) to the usual standard of care is more effective than the usual standard of care alone, and whether it is more effective when delivered prior to or following bariatric surgery.

Primary Outcome Measures:
  • Changes in Depression severity [ Time Frame: Baseline, weekly up to 6 weeks and post-intervention, 6 months and 1 year after bariatric surgery ]
    Measured with "Patient Health Questionnaire" (PHQ-9),a 9-item self-report measure of depression severity

  • Changes in Anxiety severity [ Time Frame: Baseline, post-intervention, 6 months, and one year after bariatric surgery ]
    Measured by "Generalized Anxiety Disorder Questionnaire" (GAD-7) ,a 7-item self report measure of anxiety severity

  • Changes in Health-related quality of life [ Time Frame: Baseline, post-intervention, 6 months, and one year after bariatric surgery ]
    Measured by "Short-Form Health Survey" (SF-36), a 36-item self-report measure of health-related quality of life.

  • Changes in eating pathology [ Time Frame: Baseline, post-intervention, 6 months, and 1 year after bariatric surgery ]
    Measured by the "Binge Eating Scale" (BES) and "Emotional Eating Scale" (EES). The BES is a 16-item self-report measure designed specifically for use with obese individuals that assesses binge eating behaviors as well as associated cognitions and emotions. The EES is a 25-item self-report measure that assesses the tendency to cope with negative affect by eating.


Secondary Outcome Measures:
  • Comparing improvements on the outcome of Tele-CBT before and after bariatric surgery [ Time Frame: One year follow-up ]
    Half the subjects will receive the CBT intervention prior to surgery, and half will receive it after surgery; they will be followed until 1 year post surgery.

Detailed Description:

Preliminary research suggests that CBT might be effective in reducing eating pathology and improving surgical outcomes.

However, previous studies have examined group-based CBT delivered in person, and most patients cannot feasibly attend weekly therapy appointments at the hospital. Telephone-based CBT offers greater convenience because the service can be delivered during the evening and weekends, and eliminates the need to leave work and travel to hospital appointments. No published studies have examined the effectiveness or feasibility of telephone-based CBT for bariatric surgery patients. This study will examine the effectiveness of Tele-CBT as an adjunctive treatment to the usual standard of care in bariatric surgery patients.
