1 Measures of Compulsive Buying : Applications and Recommendations

In this article we investigate the validity of two main scales in the Netherlands; the broadly applied Clinical Screener (CS) and the newly developed and promising Compulsive Buying Index (CBI). Our results indicate problems concerning convergent and discriminant validity of both scales. After eliminating the first item the construct validity of the CBI scale is restored. However, even eliminating two items that are inappropriate in Europe, does not correct the problems of the CS scale. Nomological validity is confirmed for both scales. These results suggest better transferability of the CBI scale to the Netherlands and to Europe than of the CS scale.
