Regression-Based Norms for the Hopkins Verbal Learning Test-Revised and the Rey-Osterrieth Complex Figure in a Portuguese Adult Population.

Abstract

The principal goal of this study was to produce adjusted normative data for European Portuguese native speakers from Portugal on 2 neuropsychological tests widely used to assess learning and memory: the Hopkins Verbal Learning Test-Revised (HVLT-R) and the Rey-Osterrieth Complex Figure Test (ROCF). The study included 300 individuals aged 18-92years (M=50.4, SD=21.2), who had educational backgrounds ranging from 3 to 25years (M=10.4, SD=5.2). Age, education, and sex were significantly associated with HVLT-R and ROCF performance. These demographic variables accounted for 61% of the variance in HVLT-R total recall, 54% in HVLT-R delayed recall, 18% in HVLT-R recognition, 55% in ROCF copy, and 39% in ROCF immediate recall. The normative data are presented as regression-based algorithms to adjust direct and derived test scores for age, education, and sex. This study provides a calculator of normative data derived from the results of the regression models.
