Allen et al. compared performance of the BAS-D and the EBAS in a sample of 811 elderly subjects in Australia and England (8). Because the EBAS retained the most internally consistent items, alpha coefficient values were only about 0.05 lower than those for the full 21-item scale, and the area under the ROC curve was actually higher than that for the complete scale (8). Alpha internal consistency for the EBAS was 0.80 (8, p213). In three German samples, the EBAS alpha values were all 0.85, whereas for an English sample alpha was 0.86 (9, Table 1).
