Perri Spanish Auditory Verbal Learning and Memory Test: Normative Data for Elderly Adults from Mexico

TL;DR

This study provides adjusted norms for a memory test used on elderly Mexican adults, considering factors like age, sex, and education.

Contribution

The study introduces regression-based norms for the Perri-AVLT tailored to elderly Mexican adults.

Findings

Years of education significantly predicted cognitive performance across all Perri-AVLT trials.

The Pearson correlation for all Perri-AVLT trials was high, indicating strong reliability.

The norms can help neuropsychologists assess and support cognitive evaluation in elderly Mexican adults.

Abstract

Background: The Perri Auditory Verbal Learning Test (Perri-AVLT) is a cognitive tool designed to assess verbal learning and memory. Currently, demographically adjusted norms for the Perri-AVLT are not available for elderly Mexican adults. Objective: This study aimed to develop regression-based norms from elderly Mexican adults to enable demographic adjustments for clinical interpretation. Methods: The sample included 294 elderly Mexican adults aged 60–89 (224 cognitively normal individuals, and 70 clinical cases) from Mexico (Jalisco, Guanajuato, and Mexico City). Participants were administered the Perri-AVLT. A multivariate regression-based norming approach was used to evaluate the effects of age, sex, and years of education on test performance. Results: The multivariate regression model showed that years of education were a significant predictor of cognitive performance across all Perri-AVLT trials. The Pearson correlation for all Perri-AVLT trials was high. Conclusion: This study provides regression-based normative data for the Perri-AVLT adjusted for sociodemographic factors. These norms can be used to evaluate verbal learning and memory in elderly Mexican adults. This information can support a neuropsychologist in cognitive assessment, rehabilitation, and research.
