Abstract
Objectives: The goal of the present study is to provide normative data stratified by age, education and gender for the revised Rey Auditory Verbal Learning test Czech version (RAVLT) in older adults. Sample and settings: The normative sample consisted of 361 healthy older persons from 62 to 97 years of age (mean age = 75.50; SD = 8.60) and approximately of equal number of men and women, and people with lower and higher levels of education.
All participants met the anamnestic and performance criteria for cognitively healthy population. They were assessed with RAVLT as a part of neuropsychological battery.
Analysis and results: We found that performance in RAVLT total immediate recall, retention and recognition is related to age (rho = from -0.18 to -0.38; p < 0.001), education (rho = from 0.15 to 0.24; p < 0.01) and gender (rpb = from 0.13 to 0.21; p < 0.05). Regression equations allow an exact calculation of individual's performance relative to demographic data.
The most commonly used variables in clinical practice are provided in percentiles for two age groups (younger - 62-74 and older - 75+ older) separately and two groups according to education level (lower and higher). Principal component analysis showed two-factor test structure solution.
Study limitation: The main limitation of this study is a nonrandom selection of normative sample. This procedure was chosen because of financial and organizational feasibility, moreover it is commonly used in normative samples.
