Efficacy of Telephone-Based Cognitive Behavioral Therapy for Weight Loss, Disordered Eating, and Psychological Distress After Bariatric Surgery: A Randomized Clinical Trial
Authors' conclusion
This study found that tele-CBT delivered at 1 year after surgery resulted in no change in short-term weight outcomes but improved disordered eating and psychological distress. The impact of these psychosocial improvements on longer-term weight outcomes is currently being examined as part of this longitudinal multisite randomized clinical trial.
Study context
- Population
- Adults 1 year after bariatric surgery, fluent in English, with telephone and internet access; active suicidal ideation or poorly controlled severe psychiatric illness excluded; 83.3% female, mean age 47.55 years
- Participants
- 306 adults
- Comparison
- Telephone-based CBT vs standard postoperative bariatric care
- tele-CBTn = 152
- Controln = 154reference
- Primary endpoint
- Postoperative percentage total weight loss
- Follow-up
- Baseline (1 year after surgery), after the intervention (≈15 months) and 3-month (≈18 months)

- Multisite
- 3 hospital-based bariatric surgery programs
- Recruitment February 2018 to December 2021

Primary result
As reported in the abstract
Percentage total weight loss
- Group by time interaction for percentage total weight loss not significant
- Between Tele-CBT and Control: P = 0.15
Secondary outcomes
| Outcome | P value |
|---|---|
| Disordered eating: mean BES score · across all timesSignificant interaction | P < 0.001 |
| Disordered eating: EES total score · across all timesSignificant interaction | P < 0.001 |
| Psychological distress: PHQ-9 score · across all timesSignificant interaction | P < 0.001 |
| Psychological distress: GAD-7 score · across all timesSignificant interaction | P < 0.001 |
