Demographic and Autism Characteristics as Predictors of Age of Autism Diagnosis of Individuals with Autism in Paraguay

Autism is a lifelong condition characterized by repetitive and restrictive behaviors and differences in social communication. The reported prevalence of autism has risen exponentially in the past years. Early identification and subsequent early intervention are key to promoting better outcomes for autistic individuals. However, there is a dearth of research focusing on understanding variables that impact the age of diagnosis of autistic children in Paraguay. We collected data from 176 caregivers of autistic individuals aged 18 years or younger who lived in Paraguay and conducted a hierarchical regression analysis to understand whether demographic and clinical variables predicted the age of autism diagnosis in Paraguayan autistic children. Our results indicated that child's age, child's age at caregivers' first concerns for their development, and child's verbal skills were significant predictors of the age of autism diagnosis in Paraguay. Educating caregivers and professionals to increase awareness of autism characteristics and atypical behaviors in social communication beyond verbal skills may support the early identification of autism and subsequent access to early intervention.
