Objective: To develop age-adjusted norms for the semantic fluency tasks (animals, and fruits) in a group of illiterate adults from Latin America. Method: The sample consisted of 191 healthy adults from 6 different 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, have a Patient Health Questionnaire–9 (depression) score of ≤4, and have a Barthel Index of ≥90. Participants had to be illiterate (not able to read or write) to participate in the study. 59.5% of participants were women, the average age was 62.55 ± 18.3 years (range 18-90), and the average education was 0.6 ± 1.30 years. Participants had 60 seconds to complete each category in the semantic fluency task. Results: Two linear regressions showed significant effects for age on both categories: animals (β= −.156; p< .05; R2 =.019) and fruits (β= −.178; p< .05; R2 =.027), suggesting the development of different norms for illiterate adults. Thus, two multinomial logistic regression were run and yielded main effects of age groups for the semantic fluency scores (r2 Cox & Snell > .071, p's < .001). Consequently, correction tables by age were created, and tables of percentiles were calculated based on the distribution of corrected scores. Conclusion: To date, this is the first study to create semantic fluency norms in Latin America with an illiterate adult population and to include appropriate adjustments for age. These data represent a critical advancement in the assessment of illiterate adults in Latin America.
