: Objective: To evaluate the psychometric properties of the Shortened Version of the Token Test (SVTT), the Peabody Picture Vocabulary Test (PPVT-III), and the Rey–Osterrieth Complex Figure (ROCF) using an item response theory (IRT) framework and to establish normative data for Waranka children and adolescents based on their ability scores. Methods: A total of 436 healthy people aged between 6 and 17 participated in this study. The factor structure was evaluated using confirmatory factor analysis (CFA) and the difficulty and discrimination parameters using IRT through the two-parameter logistic model for the SVTT and PPTV-III, while for the ROCF, the graded response model was used. The ordinal alpha and McDonald’s omega were used for reliability. Results: For most items, a low ability was enough to achieve the highest scores for the ROCF and SVTT. For the PPVTIII, the items aligned sequentially based on the difficulty, and a low level of ability was enough to achieve the highest score for the first 40 items. The ROCF, SVTT, and PPVTIII demonstrated adequate reliability. The ROCF copy and immediate recall scores were influenced by the mean parents’ years of education (MPE) and quadratic age interaction. The SVTT performance was affected by the quadratic age and sex interaction, and the PPVT-III by the interaction effect of the MPE and quadratic age. Conclusions: This is the first study to analyze the psychometric properties of the ROCF, SVTT, and PPVT-III through IRT models that are accurate and relevant for the validity of the obtained data and generate normative data in the under-represented nation of Ecuador for clinical and research purposes.

(SAGE, 2024-09-20) Rivera, Diego; Forte, Anabel; Olabarrieta Landa, Laiene; Perrin, Paul B.; Arango Lasprilla, Juan Carlos; Ciencias de la Salud; Osasun Zientziak
Objective: To present the methodology for a study generating normative neuropsychological test data for healthy Spanish-speaking adults (18-80 years old) living in the U.S. using Bayesian inference as a novel approach. Method: The study sample consisted of 253 healthy adults from eight U.S. regions (California, Connecticut, Florida, Indiana, New Jersey, Oregon, Virginia, and Wisconsin), with individuals originating from a diverse array of Latin American countries. To participate in the study, individuals must have met the following criteria: were between 18 and 80 years of age, had lived in the U.S. for at least 1 year (12 continuous months), self-identified Spanish as their dominant language, had at least one year of formal education, were able to read and write in Spanish at the time of evaluation, scored ¿23 on the Mini-Mental State Examination, scored <10 on the Patient Health Questionnaire¿9, and scored <10 on the Generalized Anxiety Disorder scale. Participants completed 12 neuropsychological tests. Reliability statistics and norms were calculated for all tests. Conclusions: This was the first normative study for Spanish-speaking adults in the U.S. to implement demographic, acculturation, and bilingual dominance measures as possible controls. Additionally, it was the first study to use Bayesian linear or generalized linear regression models for generating normative data in neuropsychology.

(American Psychological Association, 2023) Del Cacho Tena, Ana María; Merced, Kritzia; Perrin, Paul B.; Arango Lasprilla, Juan Carlos; Olabarrieta Landa, Laiene; Rivera, Diego; Ciencias de la Salud; Osasun Zientziak
Objective: 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.

(Taylor & Francis, 2024-07-01) Fierro Bósquez, María José; Olabarrieta Landa, Laiene; Christ, Bryan R.; Arjol, David; Perrin, Paul B.; Arango Lasprilla, Juan Carlos; Rivera, Diego; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
Objective: To generate normative data (ND) for executive functions tests in the Waranka minority population of Ecuador. Method: Four-hundred participants aged 6–17 completed the Symbol-Digit Modalities Test (SDMT), Trail-Making Test (TMT), Modified-Wisconsin Card Sorting Test (M-WCST), and Test of Colors-Words (STROOP). Scores were normed using multiple linear regressions, including age, age2, natural logarithm of mean parent education (MPE), sex, bilingualism, and two-way interactions as predictors. Results: Age by MPE and Age2 by MPE interactions arose for SDMT, so that children with illiterate parents scored lower than those with literate parents. Girls scored higher in SDMT. All TMT and M-WCST scores were influenced by age2. Age by MPE interaction was found for TMT–A, so that children with higher MPE went faster; and age by bilingualism interaction for TMT–B, so that more bilingual children needed less time. Stroop-Word and Color were influenced by age2 by MPE interaction, so that children, while older, scored higher, especially those with higher MPE. Also, age2 by sex interaction arose, so that girls increased scores curvilinearly while boys linearly. Word-Color was influenced by age, while Stroop-interference by age2. Age by MPE interaction was found for MCST-Categories and Perseveration, so that perseverations decreased to then increased, especially in those with illiterate parents. M-WCST-Category scores increased to then decrease later on age in children with illiterate parents. Z-scores calculated through indigenous ND were significantly lower than generated through non-indigenous norms. Conclusions: ND for minority populations are critical since Waranka sample performed worse when using non-indigenous norms for z-score calculation.

Normative data for verbal fluency and naming tests in Spanish-speaking adults in the United States
(SAGE, 2024-08-22) Olabarrieta Landa, Laiene; Rivera, Diego; Xia, Bridget; Moreno, Oswaldo; Ramos Usuga, Daniela; Morel Valdés, Gloria M.; López, Enrique; Rodríguez, Miriam J.; Carrión, Carmen I.; Lequerica, Anthony H.; Drago, Christin I.; García, Patricia; Rivera, Patricia M.; Perrin, Paul B.; Arango Lasprilla, Juan Carlos; Ciencias de la Salud; Osasun Zientziak
Background: The Rey-Osterrieth Complex Figure Test (ROCFT) and the Clock Drawing Test (CDT) are commonly used in clinical practice. The ROCFT measures constructional praxis, visual perception, and visuospatial learning and memory and the CDT assesses for visuospatial, constructional, and executive difficulties. Several neurological disorders are associated with visuospatial and visuoconstructional impairments, yet reliable normative data accounting for sociodemographic aspects of identity and acculturative variables are scarce for Hispanics living in the U.S. Objective: To generate normative data for the ROCF and CDT in a Spanish-speaking adult population living in the U.S. Methods: The sample consisted of 245 participants¿ cognitively normal adults, recruited from several states in the U.S. Each participant was administered the ROCFT and CDT as part of a larger cognitive battery. The ROCFT and CDT were normed using a Bayesian approach. Age, age2, education, sex, acculturation, and language competence, were included as predictors in the analyses. Results: ROCFT was associated with education and age, particularly as they interact with Spanish language competency, and time spent in the U.S. Education was significantly associated with recall abilities and a lower memory recall on the ROCFT. Age was found to vary depending on a person¿s bilingual abilities. Sex did not emerge as a predictor of performance, and it was not moderated by other variables. Conclusions: This is the first study to include acculturation and language proficiency variables in the creation of norms for the assessment of visuoconstruction abilities. This study will have a large impact on the practice of neuropsychology in the U.S.

(Oxford University Press, 2024) Del Cacho Tena, Ana María; Christ, Bryan R.; Arango Lasprilla, Juan Carlos; Perrin, Paul B.; Rivera, Diego; Olabarrieta Landa, Laiene; Ciencias de la Salud; Osasun Zientziak; Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa
Objective: To quantify the evolution, impact, and importance of normative data (ND) calculation by identifying trends in the research literature and what approaches need improvement. Methods: A PRISMA-guideline systematic review was performed on literature from 2000 to 2022 in PubMed, Pub-Psych, and Web of Science. Inclusion criteria included scientific articles about ND in neuropsychological tests with clear data analysis, published in any country, and written in English or Spanish. Cross-sectional and longitudinal studies were included. Bibliometric analysis was used to examine the growth, productivity, journal dispersion, and impact of the topic. VOSViewer compared keyword co-occurrence networks between 1952¿1999 and 2000¿2022. Results: Four hundred twelve articles met inclusion and exclusion criteria. The most studied predictors were age, education, and sex. There were a greater number of studies/projects focusing on adults than children. The Verbal Fluency Test (12.7%) was the most studied test, and the most frequently used variable selection strategy was linear regression (49.5%). Regression-based approaches were widely used, whereas the traditional approach was still used. ND were presented mostly in percentiles (44.2%). Bibliometrics showed exponential growth in publications. Three journals (2.41%) were in the Core Zone. VOSViewer results showed small nodes, long distances, and four ND-related topics from 1952 to 1999, and there were larger nodes with short connections from 2000 to 2022, indicating topic spread. Conclusions: Future studies should be conducted on children¿s ND, and alternative statistical methods should be used over the widely used regression approaches to address limitations and support growth of the field.
