Multivariate Base Rates of Low Scores on Tests of Learning and Memory Among Latino Adult Populations.

OBJECTIVE: To determine the prevalence of low scores for two neuropsychological tests with five total scores that evaluate learning and memory functions. METHOD: N = 5402 healthy adults from 11 countries in Latin America and the commonwealth of Puerto Rico were administered the Rey-Osterrieth Complex Figure (ROCF) and the Hopkins Verbal Learning Test (HVLT-R). Two-thirds of the participants were women, and the average age was 53.5 ± 20.0 years. Z-scores were calculated for ROCF Copy and Memory scores and HVLT-R Total Recall, Delayed Recall, and Recognition scores, adjusting for age, age2, sex, education, and interaction variables if significant for the given country. Each Z-score was converted to a percentile for each of the five subtest scores. Each participant was categorized based on his/her number of low scoring tests in specific percentile cutoff groups (25th, 16th, 10th, 5th, and 2nd). RESULTS: Between 57.3% (El Salvador) and 64.6% (Bolivia) of the sample scored below the 25th percentile on at least one of the five scores. Between 27.1% (El Salvador) and 33.9% (Puerto Rico) scored below the 10th percentile on at least one of the five subtests. Between 5.9% (Chile, El Salvador, Peru) and 10.3% (Argentina) scored below the 2nd percentile on at least one of the five scores. CONCLUSIONS: Results are consistent with other studies that found that low scores are common when multiple neuropsychological outcomes are evaluated in healthy individuals. Clinicians should consider the higher probability of low scores when evaluating learning and memory using various sets of scores to reduce false-positive diagnoses of cognitive deficits.

Hispanic neuropsychologists in the United States: What do we know about them and how can the field address their needs?

BACKGROUND: Despite numerous calls throughout the years for an increase in ethnic, cultural, and racial diversity within the field of psychology, it remains an elusive reality for Hispanic neuropsychology practitioners in the United States (U.S.). OBJECTIVE: 1. Determine the background and current work situation of Hispanic clinical neuropsychologists in the U.S. (e.g., professional training, assessment and diagnostic procedures used, rehabilitation techniques employed, populations targeted, teaching responsibilities, and research activities), and 2. Examine issues related to perceived discrimination in the field of neuropsychology and what this means for our profession. METHODS: The sample consisted of 107 Hispanic neuropsychologists residing among the 50 United States, District of Columbia, and Puerto Rico who took a survey of professional practices and experiences in clinical neuropsychology. RESULTS: Our findings confirm that Hispanic neuropsychologists in the U.S. are culturally diverse, present with varied levels of bilingualism, have been faced with discrimination during training and in their workplace, and compare favorably with non-Hispanic neuropsychologists in terms of education and clinical training. CONCLUSIONS: Transforming neuropsychology into a diverse and inclusive field requires intentional, strategic, and systematic interventions in education, academia, training, professional organizations and in research.

Normative data for verbal fluency in healthy Latin American adults: Letter M, and fruits and occupations categories.

OBJECTIVE: To generate normative data for the verbal fluency tests (VFT-letter M, fruits, and occupations categories) in Spanish-speaking adult populations, with country-specific adjustments for age, education, and sex when appropriate. METHOD: The sample consisted of 3,977 healthy adults from 11 countries in Latin America (Argentina, Bolivia, Chile, Cuba, El Salvador, Guatemala, Honduras, Mexico, Paraguay, Peru, and Puerto Rico; sample size per country ranged between n = 184 and n = 1,300). Each participant was administered the VFT as part of a larger neuropsychological battery. Scores for letter M, fruits, and occupations categories were normed using multiple linear regressions. The country-specific regression models included age, age2, education, education2, and sex as predictors. RESULTS: The final multiple linear regression models showed that age affected the performance on these tests but not uniformly. For example, M letter scores decrease linearly with age except for Argentina, Guatemala, and Mexico, in which quadratic age effect was found. Scores also increase linearly as a function of education but not in all countries. For example, a quadratic education effect was found for the fruits category in Bolivia, Honduras, and Paraguay. Sex had a significant impact on the M letter category fluency in Guatemala, fruits category in Guatemala and Peru, and occupations' category in Mexico. CONCLUSIONS: This study presents verbal fluency test normative data across 11 countries in Latin America. These norms are expected to be useful for neuropsychologists of these countries.
