Questionnaire data concerning spelling and reading self-assessment, habits, and school history were obtained for 79 adults (54 women and 25 men). The items were used to predict affectedness as defined on the basis of psychometric tests. For this purpose, two different discriminant analytical approaches (linear discriminant analysis and hierarchical classification with CART) were compared using a cross-validation design. 86.8–92.6% of the learning sample and 87.5–88% of the cross-validation sample were classified correctly. The CART model was preferred due to a balanced relation of sensitivity and specificity. Our results support the conclusion that self-report data are appropriate to substitute psychometric tests if these cannot be administered.  相似文献
