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

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.
