Swedish Enlistment Battery (SEB): Construct Validity and Latent Variable Estimation of Cognitive Abilities by the CAT‐SEB

Abstract

Modern computer technology permits efficient evaluation of test scores in terms of basic orthogonal factors of ability. A three‐level hierarchical model of cognitive abilities was used as the theoretical basis of the computerized Swedish Enlistment Battery (CAT‐SEB). Structural analysis of ten ability tests on a sample of 1,436 conscripts by confirmatory factor analysis (tested by the LISREL system) revealed a general, a verbal and a spatial factor ‐‐ although the determinacy of the latter was weak. A nested factor model was used, with direct influences of the latent variables on the tests. This result is a construct validity evaluation of the testing system. Unrelated factor scores of the three latent variables comprise the output of the testing system. Future research should evaluate the efficiency of the prediction from the latent variables.
