    (IOS Press, 2017) Aguilar Rivera, Daniel; Salinas, C.; Ramos Usuga, D.; Delgado Mejía, I.; Vasallo Key, Y.; Hernández Agurcia, G.; Valencia Vásquez, J.; García Guerrero, Cristina Elizabeth; Garcia de la Cadena, Claudia; Rabago Barajas, B.; Romero García, I.; Campos Varillas, A.; Sánchez Sansegundo, Miriam; Galvao Carmona, Alejandro; Lara, Laura; Granja Gilbert, E.J.; Martín Lobo, Pilar; Velázquez Cardoso, J.; Caracuel, A.; Arango Lasprilla, Juan Carlos
    OBJECTIVE: To generate normative data for the Concentration Endurance Test (d2) in Spanish-speaking pediatric populations. METHOD: The sample consisted of 4,373 healthy children from nine countries in Latin America (Chile, Cuba, Ecuador, Guatemala, Honduras, Mexico, Paraguay, Peru, and Puerto Rico) and Spain. Each participant was administered the d2 test as part of a larger neuropsychological battery. The Total number of items processed (TN), Total number of correct responses (CR), Total performance (TP), and Concentration performance (CP) scores were normed using multiple linear regressions and standard deviations of residual values. Age, age 2, sex, and mean level of parental education (MLPE) were included as predictors in the analyses. RESULTS: The final multiple linear regression models showed main effects for age on all scores, such that scores increased linearly as a function of age. TN scores were affected by age 2 for Guatemala and Puerto Rico; CR scores were affected by age 2 for Mexico; TP scores were affected by age 2 for Chile, Mexico, Puerto Rico, and Spain; and CP scores for Mexico and Spain. Models indicated that children whose parents had a MLPE >12 years obtained higher scores compared to children whose parents had a MLPE?12 years for Mexico and Spain in all scores, and Puerto Rico for TN, CR, and TP, and Guatemala and Paraguay for CP scores. Sex affect the scores for Ecuador and Honduras (CP scores). CONCLUSIONS: This is the largest Spanish-speaking pediatric normative study in the world, and it will allow neuropsychologists from these countries to have a more accurate approach to interpret the d2 test in pediatric populations. © 2017 - IOS Press and the authors.

    Trail Making Test: Normative data for the Latin American Spanish-speaking pediatric population
    (IOS Press, 2017) Arango Lasprilla, Juan Carlos; Aguilar Rivera, Daniel; Ramos Usuga, D.; Vergara Moragues, Esperanza; Montero López, E.; Adana Díaz, L.; Aguayo Arelis, A.; García Guerrero, Cristina Elizabeth; Garcia de la Cadena, Claudia; Llerena Espezúa, X.; Lara, Laura; Padilla López, Alfredo; Rodriguez Irizarry, W.; Alcazar Tebar, C.; Irías Escher, Maria; Llibre Guerra, J.; Torales Cabrera, N.; Rodríguez Agudelo, Yaneth; Ferrer Cascales, R.
    OBJECTIVE: To generate normative data for the Trail Making Test (TMT) in Spanish-speaking pediatric populations. METHOD: The sample consisted of 3,337 healthy children from nine countries in Latin America (Chile, Cuba, Ecuador, Guatemala, Honduras, Mexico, Paraguay, Peru, and Puerto Rico) and Spain. Each participant was administered the TMT as part of a larger neuropsychological battery. The TMT-A and TMT-B scores were normed using multiple linear regressions and standard deviations of residual values. Age, age 2, sex, and mean level of parental education (MLPE) were included as predictors in the analyses. RESULTS: The final multiple linear regression models showed main effects for age on both scores, such that as children needed less time to complete the test while they become older. TMT-A scores were affected by age 2 for all countries except, Cuba, Guatemala, and Puerto. TMT-B scores were affected by age 2 for all countries except, Guatemala and Puerto Rico. Models indicated that children whose parent(s) had a MLPE >12 years of education needed less time to complete the test compared to children whose parent(s) had a MLPE ?12 years for Mexico and Paraguay in TMT-A scores; and Ecuador, Mexico, Paraguay, and Spain for TMT-B scores. Sex affected TMT-A scores for Chile, Cuba, Mexico, and Peru, in that boys needed less time to complete the test than girls. Sex did not affect TMT-B scores. CONCLUSIONS: This is the largest Spanish-speaking pediatric normative study in the world, and it will allow neuropsychologists from these countries to have a more accurate approach to interpret the TMT in pediatric populations. © 2017 - IOS Press and the authors.

    Verbal fluency tests: Normative data for Spanish-speaking pediatric population
    (IOS Press, 2017) Olabarrieta Landa, L.; Aguilar Rivera, Daniel; Lara, Laura; Rute Pérez, Sandra; Rodríguez Lorenzana, Alberto; Galarza del Angel, Javier; Peñalver Guia, Ana Ivis; Ferrer Cascales, R.; Velázquez Cardoso, J.; Campos Varillas, A.; Ramos Usuga, D.; Chino Vilca, B.; Aguilar Uriarte, M.; Martín Lobo, Pilar; Garcia de la Cadena, Claudia; Postigo Alonso, B.; Romero García, I.; Rabago Barajas, B.; Irías Escher, Maria; Arango Lasprilla, Juan Carlos
    OBJECTIVE: To generate normative data for the phonological and semantic verbal fluency tests (VFT) in Spanish-speaking pediatric populations. METHOD: The sample consisted of 4,373 healthy children from nine countries in Latin America (Chile, Cuba, Ecuador, Guatemala, Honduras, Mexico, Paraguay, Peru, and Puerto Rico) and Spain. Each participant was administered the VFT as part of a larger neuropsychological battery. Scores for letters F, A, S, and animals and fruit categories were normed using multiple linear regressions and standard deviations of residual values. Age, age 2, sex, and mean level of parental education (MLPE) were included as predictors in the analyses. RESULTS: The final multiple linear regression models showed main effects for age on all scores, such that scores increased linearly as a function of age. Age 2 had a significant effect in Chile (animals), Cuba (A letter, fruits), Ecuador (animals, fruits), Honduras (F letter), Mexico (animals, fruits), Peru (fruits), and Spain (S letters, animals, fruits). Models showed an effect for MLPE in Chile (A letters, animals, fruits), Ecuador (S letter, animals, fruits), Guatelama (F, S letter, animals), Honduras (animals), Mexico (F, A, S letters, animals, fruits), Puerto Rico (A, letters, animals), and Spain (all scores). Sex scores were found significant in Chile (animals), Ecuador (A letter, fruits), Mexico (F letter, fruits), Paraguay (F, A, S letters, fruits), Puerto Rico (F letter, animals, fruits), and Spain (F letter, fruits). CONCLUSIONS: This is the largest multi-national Spanish speaking-pediatric normative study in the world, and as such it will allow neuropsychologists from these countries to have a more accurate way to interpret the phonological and semantic VFT in pediatric populations. © 2017 - IOS Press and the authors.
