A later autism spectrum disorder diagnosis has been associated with negative consequences, as it might imply later access to services. This study aims to identify factors associated with the age of autism spectrum disorder diagnosis as reported by 2520 caregivers of autistic children from six Latin America and Caribbean Countries. Results indicate that on average, caregivers were concerned about their child?s development by 22?months of age; however, the diagnosis was 24?months later. Current age of autistic individuals, better language abilities, and having public health coverage increased the age of diagnosis. On the contrary, the presence of medical comorbidities, severity level, and type of diagnosis decreased the age of diagnosis. The age of diagnosis of autistic individuals in Latin America and Caribbean Countries corresponded to the start of formal schooling despite a much earlier age of first noticed developmental concern, highlighting the need to reduce this age gap and increase children?s probability of benefiting from early intervention. Taken together, autism spectrum disorder personal/clinical characteristics and access to health service are the main determinants for the age of diagnosis. Lay abstract An earlier diagnosis of autism spectrum disorder might lead to earlier intervention. However, people living in Latin American and Caribbean countries do not have much knowledge about autism spectrum disorder symptoms. It has been suggested that the older a child is when diagnosed, the fewer opportunities he or she will have to receive services. We asked 2520 caregivers of autistic children in six different Latin America and Caribbean Countries, the child?s age when they noticed some developmental delays and their child?s age when they received their first autism spectrum disorder diagnosis. Results indicate that, on average, caregivers were concerned about their child?s development by 22?months of age; however, the diagnosis was received when the child was 46?months of age. In addition, older children with better language abilities and public health coverage (opposed to private health coverage) were diagnosed later. On the contrary, children with other medical problems and more severe behaviors received an earlier diagnosis. In our study, children were diagnosed around the time they entered formal schooling, delaying the access to early intervention programs. In summary, the characteristics of the autistic person and the type of health coverage influence the age of diagnosis in children living in Latin America and Caribbean Countries.

In order to strengthen autism spectrum disorder research collaborations and awareness in the region, the Latin American Autism Spectrum Network (Red Espectro Autista Latinoamerica) was constituted in 2015, comprising researchers and clinicians from the following six countries: Brazil Argentina, Chile, Uruguay, Venezuela, and the Dominican Republic. This first multisite study from the Red Espectro Autista Latinoamerica network aims to describe the challenges and priorities to identify barriers to care and to map stigma among families of individuals with autism spectrum disorder living in Latin America. A total of 2942 caregivers from these six countries completed an online survey showing that the main priorities were greater community awareness and improvements in the educational system for individuals with autism spectrum disorder. In addition to that, the main barriers to care were related to lack of structure, mainly waiting lists (50.2%), high treatment costs (35.2%), and lack of specialized services (26.1%). Stigma experienced by families was frequent: one third reported feeling discriminated against and helpless for having a child with autism spectrum disorder. Also, 48.8% of the caregivers declared financial problems, 47.4% of them had to cut down work hours, and 35.5% had to leave their jobs because of their child's autism spectrum disorder. This is a pioneer study providing a description of the needs and challenges faced by families affected by autism spectrum disorder in Latin America, helping to build data-driven strategies at the national and regional levels.

Service encounters across the lifespan in individuals with autism spectrum disorders: Results from a multisite study in Latin America / Cecilia MONTIEL-NAVA in Research in Autism Spectrum Disorders, 79 (November 2020)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 79 (November 2020) . - 101670 Titre : Service encounters across the lifespan in individuals with autism spectrum disorders: Results from a multisite study in Latin America Type de document : Texte imprimé et/ou numérique Auteurs : Cecilia MONTIEL-NAVA, Auteur ; Sebastián CUKIER, Auteur ; Gabriela GARRIDO, Auteur ; Daniel VALDEZ, Auteur ; Cristiane Silvestre PAULA, Auteur ; Ricardo GARCIA, Auteur ; Analia ROSOLI, Auteur ; Matías IRARRÁZAVAL, Auteur ; Alexia RATTAZZI, Auteur Article en page(s) : 101670 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  Lifespan  Services  Caregiver  Latin-America  Latino Index. décimale : PER Périodiques Résumé : Background Core symptoms of Autism Spectrum Disorder (ASD) continue to affect everyday life as children grow and transition into adulthood. That way, different services may be needed at various stages of their lifetimes. This study aimed to describe service encounters and hours of service per week for individuals with ASD in Latin American countries and compare the data from three age groups (preschoolers, school-aged, and adolescents). Methods The data were obtained from an online survey adapted by Red Espectro Autista Latinoamerica (REAL) in 6 different South & Central American countries. The total sample was composed of 2520 caregivers of children and adolescents with ASD. Results Service encounters for Speech, Occupational, and Behavioral Therapies decreased with patient age, while medication increased. Regardless of the age group, a large proportion of individuals (19–37 %) were not receiving treatment, and those receiving treatment got fewer hours than best practice recommendations. For adolescents, the gaps in treatment are even greater and less consistent. Discussion Failure to offer timely identification and intervention for ASD will result in more impairment of the individual and the family burden. Although there are several initiatives to develop more resources for this population in Latin-America, the provision of services for ASD is still undervalued. Many such individuals might not be receiving the services they need, while most children are mainly receiving therapies with low to moderate evidence at a frequency below the recommended standards.

Validating the Child Behavior Checklist 1.5-5 as a screening tool for autism spectrum disorder / Norton KITANISHI in Autism, 29-4 (April 2025)  

Public ISBD [article]  inAutism > 29-4 (April 2025) . - p.1072-1079 Titre : Validating the Child Behavior Checklist 1.5-5 as a screening tool for autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Norton KITANISHI, Auteur ; Daniela BORDINI, Auteur ; Marcos V V RIBEIRO, Auteur ; Cristiane Silvestre PAULA, Auteur ; Helena BRENTANI, Auteur ; Joana PORTELESE, Auteur ; Pamela J SURKAN, Auteur ; Silvia S MARTINS, Auteur ; Jair de JESUS MARI, Auteur ; Paola Matiko MARTINS OKUDA, Auteur ; Sheila C CAETANO, Auteur Article en page(s) : p.1072-1079 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  child behavior  diagnosis  screening  validity Index. décimale : PER Périodiques Résumé : Early identification of autism spectrum disorder through cost-effective screening is crucial in low- and middle-income countries. The Child Behavior Checklist 1.5-5, using the Autism Spectrum Problems and Withdrawn Syndrome subscales, has potential as a level 1 autism spectrum disorder screening tool, though its construct validity in low- and middle-income countries remains underexplored. We aimed to validate the Child Behavior Checklist 1.5-5 for autism spectrum disorder screening in a representative sample of 1292 Brazilian children aged 3-5?years and 70 autism spectrum disorder children aged 1-5?years. Confirmatory factor analysis evaluated model fit indices and correlation strength between Child Behavior Checklist items and autism spectrum disorder diagnoses. Receiver operating characteristic curves assessed the optimal cutoff score. The Autism Spectrum Problems model demonstrated good fit and reliability (comparative fit index = 0.96, root mean square error of approximation = 0.037, ? = 0.869), as did the Withdrawn Syndrome model (comparative fit index = 0.974, root mean square error of approximation = 0.034, ? = 0.776), with one item per model showing low factor loadings. A cutoff score of 6 on the Autism Spectrum Problems yielded 82.5% sensitivity and 83.4% specificity, while a cutoff of 4 on the Withdrawn scale resulted in 87.9% sensitivity and 82.2% specificity. The Child Behavior Checklist 1.5-5 Autism Spectrum Problems and Withdrawn scales are reliable level 1 autism spectrum disorder screeners for Brazilian children, with good internal consistency and construct validity.Lay abstract Early identification of Autism Spectrum Disorder is very important, especially in low and middle-income countries, where access to resources is often limited. The Child Behavior Checklist 1.5-5 is a tool that has been used to help identify children with autism spectrum disorder through specific behavior patterns. However, its effectiveness in low- and middle-income country settings has not been thoroughly studied. This research focused on evaluating the Child Behavior Checklist 1.5-5 as a screening tool for autism spectrum disorder among Brazilian children. The study involved 1292 children aged 3-5?years from the general population and 70 children with autism spectrum disorder aged 1-5?years. Using advanced statistical methods, the study tested how well the Child Behavior Checklist identified children with autism spectrum disorder and how reliable it was in this context. The findings showed that the Child Behavior Checklist 1.5-5 performed well in identifying autism spectrum disorder, with high reliability and consistency in the results. Although one item in each of the autism spectrum problems and withdrawn syndrome subscales did not perform as strongly, the overall tool was effective. In summary, the Child Behavior Checklist 1.5-5 proves to be a reliable and valid tool for early autism spectrum disorder screening in Brazilian children. This can help ensure that more children in low- and middle-income country settings are identified early and receive the necessary support and interventions to help them thrive. Future research should continue to test this tool in different contexts to confirm its usefulness across various populations.
