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. Furthermore, there are additional barriers in low-income countries in access to screening tools and standardized diagnostic tests for autism spectrum disorders that were only exacerbated during COVID-19. The Brief Observation of Symptoms of Autism instrument was developed to improve access to diagnostic assessment via telehealth during this time. The current study sought to validate the use of the Brief Observation of Symptoms of Autism within two Latin American countries. A sample of 313 children and adults from Argentina and Chile were examined. Results showed valid sensitivity and specificity scores with good fit across modules using two factors (i. e. Social Affect and Restricted, Repetitive Behaviors). Preliminary results of the current study demonstrated that the Brief Observation of Symptoms of Autism is a valid instrument for Latin American population and shows promise to be used beyond the pandemic to ease the diagnostic process. This is a collaborative work with BRINCAR Parent Association, who defined the need in our country to run the validation of Brief Observation of Symptoms of Autism and gave us support as the stakeholders at Lancet Commission.
