BACKGROUND: The Beck Depression Inventory (BDI) is commonly used in the screening and evaluation process with bariatric surgery candidates despite relatively limited psychometric evidence in this @entity1 group. We examined the validity of the BDI and its clinical utility for subtyping @entity1 seeking gastric bypass surgery. METHODS: One hundred twenty-four @entity1 evaluated for gastric bypass surgery were administered the Structured Clinical Interview for DSM-IV ( @entity915 -I/P) and completed a self-report battery of psychosocial measures including the BDI. RESULTS: Based on the @entity915 -I/P, 12.9  % (n   =   16) met criteria for current @entity1316 . Receiver operating characteristic (ROC) curve analysis revealed the BDI had a good area under the curve (0.788) for predicting @entity915 -I/P @entity1316 diagnosis; BDI score of >15 optimized both sensitivity and specificity. @entity1 diagnosed with @entity915 -I/P @entity1316 had significantly higher levels of @entity1277 psychopathology, self-esteem, and shame, than those without @entity1316 . Based on a BDI cut-off score of >15, 41.9  % (n   =   52) were categorized as high-BDI and 58.1  % (n   =   72) as low-BDI. @entity1 characterized as high-BDI also had significantly higher levels of all associated measures than those with low-BDI; effect sizes for the differences by BDI subtyping were generally 2-3 times greater than those observed when comparing @entity915 -I/P-based mood versus no @entity1316 subgroups. CONCLUSIONS: In @entity1 seeking gastric bypass surgery, the BDI demonstrated limited acceptability efficiency for identifying @entity1316 with a cut-point score of >15. When identifying clinical severity, however, subtyping @entity1 by BDI scores of >15 may identify a significantly more disturbed subgroup than relying on a @entity915 -I/P-generated @entity1316 diagnosis.
