Rey Auditory-Verbal Learning Test: structure of a modified German version

Abstract

The Auditory Verbal Learning Test (AVLT) is widely used in scientific research as well as in clinical practice. But there exists little research on the structure of the AVLT. We investigated the structure of a German version of the AVLT and VLMT, in 232 patients of a psychiatric clinic and in 872 patients of an epileptologic clinic. First we stated a theoretical LISREL model relating the observed variables of the VLMT to short-term memory (STM) and long-term memory (LTM) as latent variables. Then we estimated the postulated LISREL model in the two samples. The proposed model showed excellent fit in both samples, and there were no significant deviations between the estimated and the observed covariance matrices. Thus, STM and LTM suffice to explain the structure of the VLMT, and the proposed structural equations model can be used to estimate STM and LTM capacity from VLMT data.
