Common and specific dimensions of self-reported anxiety and depression: the BDI-II versus the BDI-IA

The Beck Depression Inventory-II (BDI-II) [Beck, A.T., Steer, R. A. & Brown , G. K. (1996). Manual for Beck Depression Inventory-ii. San Antonio, TX: P sychological Corporation.] and Anxiety Inventory (BAI) [Beck, A. T. & Steer , R. A. (1993a). Manual for the Beck Anxiety Inventory. San Antonio, TX: Ps ychological Corporation.] were administered to 840 outpatients who were dia gnosed with various types of psychiatric disorders to determine whether the general symptom compositions and relative amounts of variance of the commo n and specific dimensions of self-reported anxiety and depression for these instruments would be comparable to those that had been found by Steer et a l. [Steer, R. A., Clark, D. A., Beck, A. T. & Ranieri, W. F. (1995). Common and specific dimensions of self-reported anxiety and depression: A replica tion. Journal of Abnormal Psychology, 104, 542-545.] with the BAI and amend ed Beck Depression Inventory (BDI-IA) [Beck, A. T. & Steer, R. A. (1993b). Manual for the Beck Depression Inventory. San Antonio, TX: Psychological Co rporation.]. A Schmid-Leiman transformation was used with the iterated-prin cipal-factor pattern matrix of the BAI and the BDI-II loadings and indicate d that the overall symptom compositions and relative amounts of variance th at were explained by the one common and two specific anxiety and depression dimensions were comparable to those previously found with the BDI-IA.
