Confirmatory factor analysis of the Beck XXXX individuals seeking surgery.

@entity1 @entity308 @entity353 @entity28 @entity3813
BACKGROUND: The Beck Depression Inventory (BDI) is frequently employed as measure of @entity308 in studies of @entity28 . The aim of the study was to assess the factorial structure of the BDI in @entity28 @entity1 prior to bariatric surgery. METHODS: Confirmatory factor analysis was conducted on the current published factor analyses of the BDI. Three published models were initially analysed with two additional modified models subsequently included. A sample of 285 @entity1 presenting for @entity3813 -Band surgery was used. RESULTS: The published bariatric model by Munoz et al. was not an adequate fit to the data. The general model by Shafer et al. was a good fit to the data but had substantial limitations. The @entity353 item did not significantly load on any factor in either model. A modified Shafer model and a proposed model were tested, and both were found to be a good fit to the data with minimal differences between the two. A proposed model, in which two items, @entity353 and appetite, were omitted, was suggested to be the better model with good reliability. CONCLUSIONS: The previously published factor analysis in bariatric candidates by Munoz et al. was a poor fit to the data, and use of this factor structure should be seriously reconsidered within the @entity28 population. The hypothesised model was the best fit to the data. The findings of the study suggest that the existing published models are not adequate for investigating @entity308 in @entity28 @entity1 seeking surgery.
