The Brief Observation of Symptoms of Autism: Validation study in a Latin American sample.

Autism spectrum disorder is a complex condition associated with significant impairments in social communication and behavioral functioning. Diagnosis is dependent on clinician expertise, gathering of developmental history, and observation of specific behaviors. The suggested protocols include tools rendered invalid during the pandemic, which created significant barriers for diagnostic assessments.

ECHO (Extension for Community Healthcare Outcomes) Autism STAT: A Diagnostic Accuracy Study of Community-Based Primary Care Diagnosis of Autism Spectrum Disorder.

Objective: Children can be reliably diagnosed with autism spectrum disorder (ASD) by a highly trained clinician as early as 12 to 24 months of age, but recent estimates indicate that the average age of diagnosis is 4.4 years. We hypothesized that trained primary care physicians and practitioners can reliably and accurately diagnose children 14 to 48 months with unambiguous symptoms of ASD.

Sensitivity and specificity of the autism diagnostic inventory-telephone screening in Spanish.

We report on the development in Argentina of a screening questionnaire for autism administered over the telephone. The Autism Diagnostic Inventory-Telephone Screening in Spanish (ADI-TSS) is based on the Autism Diagnostic Interview-Revised (ADI-R), keeping its structure but including fewer questions, which were rephrased to assess them over the telephone. The ADI-TSS went through different versions, with each modification gaining in reliability.
