Tele-assessment of young children referred for autism spectrum disorder evaluation during COVID-19: Associations among clinical characteristics and diagnostic outcome

Since the onset of the COVID-19 pandemic, there has been a rapid acceleration of innovative research on health services delivery, including real-world clinical implementation and evaluation of tele-assessment for the diagnosis of autism spectrum disorder. Extending this promising work, the present study examined clinical characteristics and diagnostic outcome for young children receiving autism spectrum disorder tele-assessment during the COVID-19 pandemic. The standard tele-assessment procedure included caregiver clinical interview, administration of the TELE-ASD-PEDS (TAP; a novel caregiver-mediated remote autism spectrum disorder observational assessment tool), Vineland-3, and diagnostic feedback and family counseling. Overall, our findings suggest that a definitive autism spectrum disorder diagnosis can be determined for most young children evaluated using standard tele-assessment procedures. While TAP scores and measures of adaptive functioning and Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition autism spectrum disorder symptoms are highly associated with autism spectrum disorder diagnostic outcome, a specific pattern of Restricted and Repetitive Behaviors independently predicted differential autism spectrum disorder outcome. Furthermore, our findings suggest that the TAP is useful for evaluation of at-risk children above 36 months of age with delayed language. These results add to an increasing body of research supporting use of tele-assessment, and specifically the TAP, for diagnosis of young children referred for autism spectrum disorder evaluation. Lay abstract The diagnosis of autism spectrum disorder (ASD) has traditionally been made through in-person evaluation. While the COVID-19 pandemic disrupted access to ASD services, there has been remarkable growth in research focused on novel ASD diagnostic practices, including the use of telemedicine. We implemented a standard ASD tele-assessment evaluation procedure, including use of a novel remote clinician-coached, caregiver-delivered ASD assessment tool (TELE-ASD-PEDS; TAP), with the goal of continuing to provide diagnostic services to young children and their families during the pandemic. We examined the relationship between child characteristics and diagnostic outcome for 335 children, ages 14-78 months, who received ASD tele-assessment conducted by psychologists and pediatricians in an outpatient clinic of a Midwestern academic medical center. We found that clinicians could make a determination about ASD diagnosis for most children (85%) evaluated using tele-assessment. Child clinical characteristics, including TAP scores and clinician ratings of ASD symptoms, were related to diagnostic outcome (i.e. diagnosis of ASD, no ASD, and Unsure about ASD). When all clinical characteristics were examined together, the presence of specific repetitive behaviors predicted ASD diagnosis. We also found that the TAP is effective for making an ASD diagnosis when used as part of comprehensive tele-assessment evaluation in children > 36 months of age with delayed language. Our study adds to an increasing body of research supporting use of tele-assessment for diagnosis of ASD. Although further research is needed, telemedicine may help families from different backgrounds and geographic locations to access high-quality diagnostic services.
