Study examined the feasibility, usability, and reliability of the Autism Diagnostic Observation Schedule (ADOS) Module 4 administrations delivered remotely using the Versatile and Integrated System for Telerehabilitation (VISYTER). The ADOS Module 4 is a semi-structured diagnostic assessment tool designed for verbally fluent adolescents and adults with possible autism spectrum disorder (ASD). VISYTER consists of computer stations at the client site and clinician site, and a web portal server for managing and coordinating all elements of the assessment process. Twenty-three adults with an ASD diagnosis participated in a within-subject crossover design study in which both a remote and face-to-face ADOS were administered. Weighted kappa was calculated for all 31 ADOS items. Usability and satisfaction of the remote assessment system was evaluated from the participants’ perspectives. There was substantial agreement on ADOS classification (diagnosis) between assessments delivered face-to-face versus assessments delivered remotely (intraclass correlation coefficient = .92). Non-agreement may have been due to outside factors or practice effect despite a washout period. Participant satisfaction with the remote ADOS delivery system was high. Results of this study demonstrate that an ASD assessment designed to be delivered face-to-face can be administered remotely using an integrated web-based system, with high levels of usability and reliability.
