Publication Open Access 15-item version of the Boston naming test: normative data for the Latin American spanish-speaking adult population.(American Psychological Association, 2023) Cacho Tena, Ana María del; Merced, Kritzia; Perrin, Paul B.; Arango Lasprilla, Juan Carlos; Olabarrieta Landa, Laiene; Rivera, Diego; Ciencias de la Salud; Osasun ZientziakObjective: Naming is commonly impaired in people with neurodegenerative diseases and brain injury, and as a result, its accurate assessment is essential. The aim of this study was to provide normative data for the 15-item Spanish version of the Boston Naming Test (BNT) for an adult population from eight Latin American countries/regions. Method: The total sample consisted of 2,828 participants from Argentina, Chile, Cuba, El Salvador, Mexico, Honduras, Paraguay, and Puerto Rico. Multiple regressions were used to generate normative data following a four-step process. Results: Regression models showed a linear effect of age on the 15-item BNT total score for Argentina, Chile, Mexico, and Puerto Rico. In contrast, Paraguay showed a quadratic age effect. Almost all countries showed a positive linear effect of education, except Cuba which had a quadratic effect. Sex was a significant predictor in Argentina, Chile, Cuba, and Mexico, where in women scored lower than men. Conclusions: This study generates normative data for the 15-item Spanish version of the BNT and offers a free open-source calculator that will assist in the efficacious use of this neuropsychological test in clinical practice and research.Publication Open Access Normative data for ten neuropsychological tests for the Guatemalan pediatric population updated to account for vulnerability(MDPI, 2021) Ibáñez Alfonso, Joaquín A.; Company-Córdoba, Rosalba; Cadena, Claudia de la; Simpson, Ian C.; Rivera, Diego; Sianes, Antonio; Ciencias de la Salud; Osasun ZientziakThe Guatemalan pediatric population is affected by a high incidence of poverty and violence. The previous literature showed that these experiences may ultimately impact cognitive performance. The aim of this article is to update the standardized scores for ten neuropsychological tests commonly used in Guatemala considering vulnerability. A total of 347 healthy children and adolescents from 6 to 17 years of age (M = 10.83, SD = 3) were assessed, controlling for intelligence, mental health and neuropsychological history. The standard scores were created using multiple linear regression and standard deviations from residual values. The predictors included were the following: Age, age squared (age2), mean parental education (MPE), mean parental education squared (MPE2), gender, and vulnerability, as well as their interaction. The vulnerability status was significant in the scores for language, attention and executive functions. To the best of our knowledge, this is the first study that includes the condition of vulnerability in the calculation of neuropsychological standard scores. The utility of this update is to help in the early detection of special needs in this disadvantaged population, promoting more accurate interventions in order to alleviate the negative effects that living in vulnerable conditions has on children and adolescents.Publication Open Access 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 ZientziakObjective: 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.Publication Open Access Normative data for tests of attention and executive functions in a sample of European Portuguese adult population(Routledge, 2021) Vicente, Selene G.; Rivera, Diego; Barbosa, Fernando; Gaspar, Nuno; Dores, Artemisa R.; Ciencias de la Salud; Osasun ZientziakObjective: The main goal of this study was to produce normative data for the Portuguese population on five neuropsychological tests frequently used to assess executive functions and attention: the Modified Wisconsin Card Sorting Test (M-WCST), the Stroop Color and Word Test, the Trail Making Test (TMT), the Brief Test of Attention (BTA), and the Symbol Digit Modalities Test (SDMT). Method: The study included 300 individuals aged between 18 and 93 years, who had educational backgrounds ranging from 3 to 25 years. Results: The influence of age, education, and sex was explored for each measure, as well as their contribution to explain the performance variance. Conclusions: The normative data are presented as regression-based algorithms to adjust direct and derived test scores for sex, age, and education. This study provides a calculator of normative data, derived from the results of the regression models.Publication Open Access 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 ZientziakObjective: 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.Publication Open Access 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 ZientziakObjective: 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.
