Objective: To compare performance on a phonological verbal fluency task (PVFT) across eleven countries of Latin America. Method: 5359 healthy adult participants from Colombia (28.1%), Mexico (25.3%), Argentina (6%), Peru (4.6%), Paraguay (4.9%), Honduras (3.5%), Chile (6%), Cuba (5.7%), Puerto Rico (5.6%), Salvador (5.2%), and Bolivia (5.3%) participated in the study. Inclusion criteria were a score of ≥23 on the Mini-Mental State Examination (MMSE), a score of ≤4 on Patient Health Questionnaire–9 (PHQ-9), and a score of ≥90 on the Barthel Index. 61.5% of the sample were woman, the average age was 53.83 ± 20.22 years (range 18-95), and the average education 9.92 ± 5.3 years (range 0-20). All participants completed the PVFT (F, A, S, and M letters). Illiterate participants (n = 201) were excluded from the analysis. Results: Multivariate analysis of variance revealed significant differences between countries in PVFT measures after controlling for age and education (F = 16.88; p < .001). Participants from Argentina scored higher on all measures: F (Mean = 12.29, CI95% 11.87:12.72), A (Mean = 11.77, CI95% 11.35:12.20), S (Mean = 11.94, CI95% 11.52:12.35), and M (Mean =12.69, CI95% 12.27:13.12). Conclusion: These results suggest that there are significant differences between countries on PVFT with higher performance for Argentinians. Perhaps is related to differences in the quality of education across countries; previous research has found a close relationship between education and verbal fluency tasks. Therefore, different normative data for each country are essential in order to perform adequate neuropsychological assessments in each country.
