Objective: To develop age-adjusted norms for the Hopkins Verbal Learning Test–Revised (HVLT-R) in a group of illiterate adults from Latin America. Method: The sample consisted of 191 healthy adults from 6 countries (Colombia, Mexico, Honduras, Salvador, Bolivia and Chile) in Latin America. Inclusion criteria were to have a Mini-Mental State Examination (MMSE) score of ≥23, a Patient Health Questionnaire–9 (depression) score of ≤4, and a Barthel Index of ≥90. Participants had to be illiterate (not able to read or write). The majority of the participants were women (59.5%), the average age was 62.55 ± 18.3 years (range 18–90), and the average education level was 0.6 ± 1.30 years. Participants were instructed to complete the HVLT-R. Results: Two linear regressions showed significant effects for age on the total recall score (β= −.163; p< .001; R2 =.022) and delayed recall score (β= –.245; p= .001; R2 =.055) in the HVLT-R, suggesting the development of different norms for illiterate adults. To generate age-adjusted norms, two multinomial logistic regression were run, and results suggested main effects for age groups on the HVLT-R scores (r2 Cox & Snell > .175, p's < .001). Therefore, tables with corrections by age and tables of percentiles were calculated based on the distribution of corrected scores. Conclusion: To date, this is the first study to develop norms for the HVLT-R and to include appropriate age-adjustments in an illiterate population from Latin America. These data represent a critical advancement in the assessment of illiterate adults in Latin America.
