STRUCTURE OF THE COMPUTER-ASSISTED BECK ANXIETY INVENTORY WITH PSYCHIATRIC-INPATIENTS

To determine the dimensions of self-reported anxiety in psychiatric in patients, the Beck Anxiety Inventory (BAI; Beck & Steer, 1990) was adm inistered by computer to 250 inpatients diagnosed with mixed disorders . An iterated principal-factor analysis was performed on the intercorr elations among the 21 BAI items using a Promax rotation. Two factors w ere found representing somatic and subjective symptoms of anxiety. The se dimensions significantly matched those previously described by Beck , Epstein, Brown, and Steer (1988) for outpatients diagnosed with mixe d psychiatric disorders. The generalizability of the somatic and subje ctive dimensions for inpatients and outpatients is discussed.
