Effective tools that predict postoperative outcomes are needed for decision-making and patient counseling. Objectives We hypothesized that a validated behavioral assessment tool, the Cleveland Clinic Behavioral Rating Scale (CCBRS), would predict excess weight loss, health-related quality of life, depression, anxiety, and alcohol use after bariatric surgery. Setting Hospital in the United States. Methods A prospective observational study with 2-year planned follow-up was conducted with patients who completed a psychological clinical interview, the Short Form 36 (SF-36) v.2 Health Survey and brief self-report questionnaires measuring depression (PHQ-9), anxiety (GAD-7), and alcohol use (AUDIT) preoperatively. At the conclusion of the preoperative psychological evaluation, the psychologist completed the CCBRS. All questionnaires were readministered at 6, 12, 18, and 24 months after surgery. Generalized estimating equations were used to assess whether any CCBRS ratings predicted surgery outcomes. Results One hundred seventy-nine patients (113 Roux-en-Y gastric bypass and 66 sleeve gastrectomy) were included in the analyses. SF-36 scores, PHQ-9 scores, and the AUDIT total scores improved significantly after surgery, while GAD-7 scores did not change appreciably. Higher preoperative CCBRS ratings predicted higher SF-36 scores, and lower PHQ-9, GAD-7 and AUDIT scores. The CCBRS social support rating predicted higher postoperative percent excess weight loss. Conclusion A behavioral rating scale (CCBRS) completed before bariatric surgery predicted postoperative weight loss, quality of life, depression, and anxiety. Therefore, this tool may prove useful in patient counseling and expectation management before surgery.enPublisher Policybariatric surgeryquality of lifebehavioral rating systemArticle
