Abstract

Background: Normative data for Spanish-speaking populations, particularly Hispanics in the U.S., is notably scarce.

Objective: This study aims to establish normative data for executive function tests (Modified Wisconsin Card Sorting Test and Stroop Color and Word Test) among Spanish-speaking Hispanics in the U.S.

Methods: We assessed 245 individuals aged 18-80 from eight U.S. states (California, Connecticut, Florida, Indiana, New Jersey, Oregon, Virginia, and Wisconsin) and employed Bayesian regression to estimate norms, considering various sociodemographic factors influencing performance.

Results: The posterior distribution suggests a high probability that age impacts SCWT performance, with older adults likely to show greater declines, particularly among those with high proficiency in Spanish. The posterior distribution suggests a stronger effect of age on M-WCST performance among individuals with longer U.S. residency. Educational attainment demonstrates a robust positive impact on M-WCST outcomes, with lower levels of education associated with a higher probability of increased errors. An interaction between education and Spanish proficiency was observed, influencing SCWT scores differently across proficiency levels. Sex and acculturation levels interact to affect SCWT performance, with distinct patterns observed between men and women. This suggests that the impact of acculturation on cognitive test performance may vary by gender.

Conclusion: Establishing culturally sensitive normative data can enhance accurate identification of executive dysfunction and reduce misdiagnosis risks. This study underscores the importance of considering sociocultural factors including acculturation and language proficiency in neuropsychological assessments to better serve diverse populations.
