The objectives of the study were i using the responses of a sample of Arab college students to the Beck Depression Inventory BDI-II in CFA to compare the goodness of fit indices of the original dimensional three-and two-factor first-order models and their modifications with the corresponding hierarchical models . higher - order and bifactor models ii to assess the psychometric characteristics of the BDI-II including convergent discriminant validity with the Hopkins Symptom Checklist HSCL-25 . Method Participants N 624 were Kuwaiti national college students who completed the questionnaires in class. CFA was done by AMOS version 16. Eleven models were compared using eight fit indices. Results In CFA all the models met most fit criteria. While the higher-order model did not provide improved fit over the dimensional first - order factor models the bifactor model BFM had the best fit indices CMNI DF GFI RMSEA . All regression weights of the dimensional models were significantly different from zero P . Standardized regression weights were mostly and all covariance paths were significantly different from zero. The regression weights of the BFM showed that the variance related to the specific factors was mostly accounted for by the general depression factor indicating that the general depression score is an adequate representation of severity. The BDI-II had adequate internal consistency and convergent discriminant validity. The mean BDI score SD was
