Development and validation of the Xhosa translations of the Beck Inventories: 3. Concurrent and convergent validity

Abstract

This article provides data on the validity of the Xhosa versions of the Beck Depression Inventory-II (XBDHI), the Beck Hopelessness Scale (XBHS) and the Beck Anxiety Inventory (XBAQ based on a sample of 122 Xhosa respondents which Included students and patients. For patients, clinicians completed rating scales of Depression and Anxiety symptoms. In tests of concurrent validity, depressed patients had significantly higher scores on the XBDI-II and XBHS than students or patients who were not depressed. Similarly anxious patients had higher scores on the XBAI than students and patients who were not anxious. Correlations with clinicians' ratings were: 91 for XBDI-II scores and depression ratings, and 88 for XBAI scores and anxiety ratings. Correlations between the three translated scales were similar to those for the original scales. These analyses provide evidence that the translated scales have levels of concurrent and convergent validity comparable to the originals.
