    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.

    Prevalence of low scores on executive functions tests in a Spanish-speaking pediatric population from 10 Latin American countries and Spain
    (Taylor & Francis, 2020) Benito Sánchez, Itziar; González, Isabel; Oliveras Rentas, Rafael E.; Ferrer Cascales, Rosario; Romero García, Ivonne; Restrepo Botero, Juan Carlos; Delgado Mejía, Iván Darío; Vergara Moragues, Esperanza; Rivera, Diego; Arango Lasprilla, Juan Carlos; Ciencias de la Salud; Osasun Zientziak
    Pediatric neuropsychologists and researchers commonly interpret a low score as a cognitive weakness. The purpose of the study was to determine the prevalence of low scores for three neuropsychological tests used to evaluate executive function in 4,595 healthy children from Latin-America and Spain. Results showed that low scores are common when multiple neuropsychological outcomes are evaluated in healthy individuals. Clinicians should consider the higher probability of low scores in a given individual when evaluating executive functions using various sets of scores to reduce false-positive diagnoses of cognitive deficits in a child.

    Multivariate base rates of low score on neuropsychological tests of individuals with coca paste use disorder
    (Oxford University Press, 2023) Vergara Moragues, Esperanza; Acosta Barreto, María Rocío; Rivera, Diego; Santiago Ramajo, Sandra; González-Saiz, Francisco; Arango Lasprilla, Juan Carlos; Ciencias de la Salud; Osasun Zientziak
    OBJECTIVE: The aim of this study was to determine the prevalence of low scores on eight commonly used neuropsychological tests to evaluate learning and memory, language, and executive functions in individuals with coca paste use disorders (CPUD) and to identify the differences with respect to a group of healthy nonconsuming subjects (HCs). METHODS: 162 Colombian adults with CPUD and a group of 162 Colombian adult HCs participated in this comparative study. Eight tests (eighteen test scores) were grouped into three categories: learning and memory, language, and executive functions. Each participant was categorized based on the number of low scoring tests in specific percentile cut-off groups (25th, 16th, 10th, 5th, and 2nd). RESULTS: In the learning and memory domain, 89.5% of individuals with CPUD and 55.6% of HCs scored below the 25th percentile on at least one of the five test scores, in the language domain, 80.7% of individuals with CPUD and 58% of HCs and in the executive function domain, 92% of individuals with CPUD and 67.3% of HCs. Having two or more scores below the 10th percentile or 10 or more at the 5th percentile shows an optimal cut-off for determining the sensitivity and specificity for discriminating between the two groups. CONCLUSIONS: The individuals with CPUD had a higher percentage of low scores than the HCs in the domains of learning and memory, language, and executive function. It is important for clinicians to be aware of low scores in individuals with CPUD to avoid false-positive diagnoses of cognitive impairment.
