![]() Such a lack of evidence about the distribution and structure of autistic symptoms in Brazil has likely contributed to the dearth of autism research in our country. Autism in Brazil: perspectives from science and society. Paula CS, Fombonne E, Gadia C, Tuchman R, Rosanoff M. with only a single study based on a small sample from a rural area evaluating how autistic symptoms are distributed in our population. Literatura científica brasileira sobre transtornos do espectro autista. Teixeira MCTV, Mecca TP, Velloso RL, Bravo RB, Ribeiro SHB, Mercadante MT, et al. Brief report: prevalence of pervasive developmental disorder in Brazil: a pilot study. Paula CS, Ribeiro SH, Fombonne E, Mercadante MT. ![]() To date, very little research has been devoted to autism in Brazil, 8 8. ![]() In other words, the standards for “typical” and “atypical” behaviors and the conceptualizations of autism symptoms could vary across cultures. Examining cross-cultural differences in autism spectrum disorder: a multinational comparison from Greece, Italy, Japan, Poland, and the United States. Matson JL, Matheis M, Burns CO, Esposito G, Venuti P, Pisula E, et al. For instance, different expectations and demands are placed on the child at home and at school across different cultures, which could help mask or unmask autistic symptoms. The need for cross-cultural research on the pervasive developmental disorders. the behavioral manifestation of autistic symptoms, as well as their clinical interpretation, is largely dependent on the cultural context to which the children, parents, teachers, and clinicians belong. Identification of common genetic risk variants for autism spectrum disorder. Grove J, Ripke S, Als TD, Mattheisen M, Walters RK, Won H, et al. 2012 54:306-12.Īlthough autism is universal and presents strong biological underpinnings, 5 5. A systematic review of two outcomes in autism spectrum disorder – epilepsy and mortality. Woolfenden S, Sarkozy V, Ridley G, Coory M, Williams K. Autism after adolescence: population-based 13- to 22-year follow-up study of 120 individuals with autism diagnosed in childhood. Although there is interindividual variation in the course of autism across the lifespan, older studies, prior to the development of early intervention strategies, have described associations between autism and negative outcomes, such as poor educational attainment, suboptimal work performance, and even a higher mortality risk than typically developing youth. Prevalence of autism spectrum disorder among children aged 8 years – autism and developmental disabilities monitoring network, 11 sites, United States, 2014. Baio J, Wiggins L, Christensen DL, Maenner MJ, Daniels J, Warren Z, et al. Autism is relatively prevalent in the general population, with estimates of ∼2% in the most recent epidemiological studies. Lord C, Brugha TS, Charman T, Cusack J, Dumas G, Frazier T, et al. ![]() These findings provide evidence that the structure of autistic symptoms in Brazil is similar to that described in other countries, indicating the cross-cultural validity of autism in Brazil.Īutism spectrum disorder autism Brazil CASTĪutism spectrum disorder (henceforth autism) is a psychiatric condition characterized by symptoms of social communication and interaction deficits, restricted, repetitive patterns of behaviors, interests, or activities, sensory anomalies and varying levels of intellectual disabilities. Results:Īutistic symptoms were best conceptualized under a correlated-factors model with two factors: one predominantly characterized by social-communication symptoms and the other by symptoms of inflexible/restricted language, behaviors, and interests. ![]() We translated the Childhood Autism Spectrum Test to Brazilian Portuguese and performed factor analyses to investigate the factor structure of parent-reported autistic symptoms in a large sample (n=8,571) of children/adolescents from a school survey in the metropolitan area of São Paulo. We used data from a large school survey to evaluate the factor structure of autism symptoms in community-dwelling children and adolescents. There is limited evidence about the cross-cultural validity of autistic symptoms in school-aged children in Brazil. ![]()
