Abstract
This study examined the factorial validity of scores on the Quick Discrimin ation Index (QDI) across three geographically dispersed samples. A multisam ple LISREL analysis, incorporating Bagozzi and Heatherton's recommended agg regate procedure, indicated that the QDI three-factor oblique model was rel atively stable across three geographically divergent samples. Coefficient a lphas across factors and samples were satisfactory. The Lix Readability Ind ex for the QDI items fell at the ninth-grade level.
