“…Given the increased awareness of the importance of early diagnosis and intervention for children with autism spectrum disorders (ASD), gold standard diagnostic measures, such as the Autism Diagnostic Observation Schedule [Lord et al, ] and Autism Diagnostic Observation Schedule‐2 (ADOS‐2 [Lord et al, ]), have become more accessible internationally for young children with ASD [Baird et al, ; Baron‐Cohen et al, ; Boilson, Staines, Ramirez, Posada, & Sweeney, ; Fombonne et al, ; Kim et al, ; Morales‐Hidalgo, Roigé‐Castellví, Hernández‐Martínez, Voltas, & Canals, ; Rudra et al, ; Sun, Allison, Matthews, et al, ]. The increased use of the ADOS‐G/ADOS‐2 in international studies has also been driven by the translation of the ADOS‐G/ADOS‐2 into more than 12 languages; however, studies examining the diagnostic validity of the measure have been mainly conducted in Western countries including the United States [Gotham, Risi, Pickles, & Lord, ], Canada [Risi et al, ], United Kingdom [Le Couteur, Haden, Hammal, & McConachie, ], the Netherlands [de Bildt et al, ], Germany [Bölte & Poustka, ], Poland [Chojnicka & Pisula, ], Greece [Papanikolaou et al, 2009], and Sweden [Zander, Sturm, & Bölte, ].…”

This study aims to provide the initial validity of the Autism Diagnostic Observation Schedule-2 (ADOS-2) Toddler Module and Module 1-2 for South Korean toddlers and preschoolers. Based on 143 children, the ASD group (n = 68) showed significantly higher ADOS-2 item and algorithm total scores as well as social affect and repetitive and restricted behaviors domain scores compared with children with nonspectrum (NS; n = 42) disorders and typically developing (TD; n = 33) children. Using lower algorithm cutoffs, sensitivities were excellent for the ASD versus NS/TD comparisons, ranging from 94% to 100% across different Modules. Specificities varied more, ranging from 82% to 100%. Internal consistency was strong with high item-total correlations (r of 0.6-0.9) and Cronbach's Alphas (all above 0.7). Results demonstrated promising, initial evidence for the validity of the ADOS-2 for South Korean toddlers and preschoolers from 1 to 4 years of age. The ADOS-2 could be implemented, with minimal adaptations, in research and clinical settings in South Korea. This study is one of the first steps toward validating the ADOS-2 in other Eastern countries that are in great need for a valid instrument for the detection of ASD.Lay Summary: Results of this study demonstrated promising, initial evidence for the validity of a gold standard measure for the diagnosis of autism, the Autism Diagnostic Observation Schedule-2 (ADOS-2), for South Korean toddlers and preschoolers.

“…A nation-wide representative study in U.K. showed that 1 in 100 children between the age group of 5-10-year-old and 1 in 125 among the 11-16-year-old children was diagnosed with autism/ASD (Green et al, 2005) A citywide study in the city of Leon (Guanajuarto) in Mexico (Fombonne et al, 2016) revealed that among the age group of 8-year-old children, 1 in 115 was diagnosed with autism/ASD. Two Japanese studies examined the prevalence of autism/ASD in two cities in Japan.…”

The prevalence of autism/autism spectrum disorder (ASD) has been increasing across the world. Previous studies in Norway reported, that the prevalence rate for 0-10-year-old children is 1 in 166, and in the case of 11-year-old children it is 1 in 125. Moreover, another nationwide study discovered that 1 in 192 males and 1 in 695 females between the ages of 1-16 years had autism in Norway in the year 2016. This study is underpinned by the data from the National Patient Registry (NPR) for registered incidences of autism/ASD (ICD-10: F84.0 Childhood autism and F84.5 Asperger syndrome). The results show that the prevalence rates of autism/ASD in the capital city of Oslo increased from 2012 to 2016 and the number of children with autism/ASD doubled during this period. Furthermore, in 2016 the results revealed that that 1 in 349 males and 1 in 1594 females between the ages of 1-5 years old had Autism/ASD. Similarly, among the age group of 6-16 years, 1 among 157 males and 1 among 544 females had autism/ASD in the capital city of Oslo in 2016. These findings suggest a 'school-age-effect' in the increase of prevalence rates among the school-age children compared to the preschool-age children. In the following study, the results are presented and discussed along with some suggestions for the educational and healthcare authorities.This study is the first of its kind and investigates the prevalence of autism/ASD among the preschool-age children (1-5 years old) and school-age children (6-16 years old) along with the gender differences in the prevalence of autism/ASD in the capital city of Oslo, Norway from 2012 to 2016.

“…En México la prevalencia de niños con TEA es de 0.87%. 3 Las teorías neuropsicológicas para explicar el TEA se han focalizado en las funciones ejecutivas (FE): procesos cognitivos que regulan el comportamiento dirigido hacia metas; dichas funciones permiten el control de los pensamientos y acciones en situaciones nuevas o complejas en las cuales no se obtiene un patrón de respuesta adaptativa. Las FE típicamente incluyen las siguientes habilidades cognitivas: inhibición, memoria de trabajo, flexibilidad, planeación y fluidez.…”

Medidas directas e indirectas de las funciones ejecutivas en niños con trastorno de espectro autista. Acta Pediatr Mex. 2018;39(1):13-22. ResumenINTRODUCCIÓN: los niños con trastorno del espectro autista (TEA) tienen dificultades en las funciones ejecutivas (FE) pero se han sugerido discrepancias entre las medidas directas e indirectas.OBJETIVO: conocer si existen diferencias en las funciones ejecutivas mediante medidas directas e indirectas entre niños con y sin TEA.MÉTODO: se incluyeron 14 varones entre primero y tercero de primaria, 50% con diagnóstico de TEA y 50% con desarrollo neurotípico, seleccionados por emparejamiento en edad y grado escolar. El promedio de edad de la muestra fue de 7.43 (DE 0.98) años. Se aplicaron las pruebas de Evaluación neuropsicológica de funciones ejecutivas en niños (ENFEN) y el Inventario de clasificación comportamental de las funciones ejecutivas (BRIEF).RESULTADOS: se encontraron diferencias significativas en las medidas de las FE indirectas, pero no en las directas, entre los grupos (p < 0.05). Así mismo, las correlaciones entre las medidas directas e indirectas fueron mayores en el grupo con TEA.CONCLUSIONES: los niños con TEA son evaluados con más dificultades en las medidas indirectas de las funciones ejecutivas, pero obtienen puntuaciones similares a los niños con desarrollo neurotí-pico cuando son evaluados en condiciones estructuradas empleando medidas directas.PALABRAS CLAVE: trastorno del espectro autista, funciones ejecutivas, desarrollo neurotípico, niños.
