| Summary: | A comprehensive analysis of interview items on the Computerized Assessment System for Psychotherapy Evaluation and Research (CASPER) was conducted using derivation (N = 1,168) and cross-validation samples (N = 1,158) from a university counseling center and an outpatient training clinic sample (N = 355). Nine scales were identified that demonstrated acceptable internal consistency and unidimensionality. Confirmatory factor analyses of 6 of these scales supported the presence of 6 factors, but indicated that several were highly intercorrelated. These findings were consistent across all 3 samples. Analyses relating these 6 scales to comparable scales on the Brief Symptom Inventory (BSI) obtained for the training clinic sample indicated a high degree of correspondence across instruments. In addition significant correlations were found between global measures obtained from CASPER and the BSI. Reprinted by permission of the publisher. |
