In-home Tele-assessment for Autism in Toddlers: Validity, Reliability, and Caregiver Satisfaction with the TELE-ASD-PEDS.

Abstract

Objective: This study focused on in-home use of a tele-assessment tool for autism diagnosis in young children, the TELE-ASD-PEDS (TAP). Psychometric properties, caregiver experiences, and perceptions of feasibility were examined among families likely to experience barriers to in-person evaluation.

Methods: One hundred eighty-two children between 18 and 42 months of age were recruited because of positive screening, primary care concerns, or early intervention referral. All participants completed initial tele-assessment including the TAP. Approximately 2 weeks later, a second visit was conducted: 92 were randomized to a repeat TAP administration by telehealth and 90 were randomized to an in-person evaluation. Caregivers completed surveys regarding challenges with technology and satisfaction with telehealth assessment.

Results: Overall, 77% of the sample was diagnosed with autism spectrum disorder (n = 140). There were few diagnostic disagreements (n = 10, 6%) between initial and second evaluations, with disagreements equally distributed between second visit type. Diagnostic outcomes (autism vs no autism) agreed between telehealth and in-person evaluation for 94% of cases, kappa = 0.82. Outcomes agreed between 2 telehealth visits for 94% of cases, kappa = 0.84. Test-retest reliability of total TAP scores across 2 administrations was strong, intraclass correlation coefficient = 0.85. Very few caregivers reported challenges with technology during telehealth appointments (<6%); 92% reported that there was nothing they would change about the telehealth visit. Examiners also reported high satisfaction with telehealth assessments.

Conclusion: In-home use of the TAP is valid, reliable, feasible, and acceptable to caregivers. Findings support the continued use of telehealth assessment for autism in toddlers, which can reduce disparities in access to timely diagnostic services.
