    Multivariate base rates of low scores on tests of learning and memory among Spanish speaking children
    (Taylor & Francis, 2020) Benito Sánchez, Itziar; Ertl, Melissa M.; Ferrer Cascales, Rosario; Oltra Cucarella, Javier; Ibáñez Alfonso, Joaquín A.; Saracostti Schwartzman, Mahia; Soto Añari, Marcio; Cadavid Ruiz, Natalia; Rodríguez Lorenzana, Alberto; Rivera, Diego; Arango Lasprilla, Juan Carlos; Ciencias de la Salud; Osasun Zientziak
    To determine the prevalence of low scores on two neuropsychological tests commonly used to evaluate learning and memory in children. 6,030 healthy children from 10 countries in Latin America and Spain were administered Rey–Osterrieth Complex Figure (ROCF) and the Test de Aprendizaje y Memoria Verbal–Infantil (TAMV-I). Results showed that low scores are common when multiple neuropsychological outcomes (tests and/or scores) are evaluated in healthy individuals. Clinicians should consider the higher probability of low scores in a given individual when evaluating learning and memory using various sets of scores to reduce false-positive diagnoses of cognitive deficits in pediatric populations.

    Normative data of neuropsychological tests of attention and executive functions in Ecuadorian adult population
    (Routledge, 2021) Rodríguez Lorenzana, Alberto; Ramos Usuga, Daniela; Adana Díaz, Lila; Mascialino, Guido; Rivera, Diego; Ciencias de la Salud; Osasun Zientziak
    Objective: The purpose of this study was to generate normative data for five tests of attention and executive functions (M-WCST, Stroop test, TMT, BTA, and SDMT), in a group of 322 Ecuadorian adults from Quito between the ages of 18 and 85. Method: Multiple regression analyzes taking into account age, education, and gender were used to generate the normative data. Results: Age and education were significantly related to test performance such that scores decreased with age and improved as a function of education. An online calculator is provided to generate normative test scores. Conclusions: This is the first study that presents normative data for tests of executive functions and attention in an Ecuadorian adult population. This data will improve the clinical practice of neuropsychology and help to develop the field in the country.

    Normative data for test of learning and memory in an Ecuadorian adult population
    (Routledge, 2020) Rodríguez Lorenzana, Alberto; Nuñez Fernández, Silvia; Adana Díaz, Lila; Mascialino, Guido; Rivera, Diego; Ciencias de la Salud; Osasun Zientziak
    Objective: The objective of this study was to develop norms for two neuropsychological tests of learning and memory in an Ecuadorian adult population. Method: 322 healthy individuals, ages between 18 and 84, were enrolled in the Metropolitan District of Quito. Participants were administered a comprehensive neuropsychological evaluation that included tests of learning and memory (Rey-Osterrieth Complex Figure Test [ROCF] and Hopkins Verbal Learning Test-Revised [HVLT-R]). Backward stepwise multiple linear regression analyses were used to examine the influence of demographic variables age, education, and gender on test performance. Normative data were developed adjusting for demographic variables found to be significant in the final regression models. Results: The final multiple linear models revealed performance on tests of learning and memory worsened with age and improved as a function of education. A user-friendly Excel-based calculator is presented to calculate the z score and percentile automatically based on raw score and sociodemographic information. Conclusion: This is the first study that presents normative data for tests of learning and memory for an adult population in Ecuador. It is expected that these norms will help to improve the clinical practice of neuropsychology in Ecuador by limiting erroneous raw score interpretation and incrementing diagnostic accuracy.

    Normative data for test of verbal fluency and naming on ecuadorian adult population
    (Frontiers Media, 2020) Rodríguez Lorenzana, Alberto; Benito Sánchez, Itziar; Adana Díaz, Lila; Paz, Clara; Yacelga Ponce, Tarquino; Rivera, Diego; Arango Lasprilla, Juan Carlos; Ciencias de la Salud; Osasun Zientziak
    Objective: To generate normative data for verbal fluency and naming test in an Ecuadorian adult population. Methods: The sample consisted of 322 healthy adults (18–84 years old) recruited from Quito, Ecuador. The verbal fluency and Boston Naming Test (BNT) were administered as part of a larger comprehensive neuropsychological battery. Multiple linear regression analyses were used to generate the normative data taking into account age, education, and sex. Results: For phonological verbal fluency, results indicated that only education was significantly related to the performance of the letters “A,” “S,” and “M.” However, the performance on the letter “F” was significantly associated with age and education. For semantic fluency, the performance on “animals” was significantly influenced by age, quadratic age, and education, whereas that for “fruits” was explained by quadratic age, education, and sex. The performance on the BNT was significantly influenced by age and education. A Microsoft Excel-based calculator was created to help clinicians to obtain the normative data on this test. Conclusion: This normative data will help neuropsychologist in Ecuador to use these tests both in research and in their clinical practice to improve the diagnosis of cognitive deficits in the population.
