Feasibility and acceptability of a telehealth model for autism diagnostic evaluations in children, adolescents, and adults

Abstract This study examined the feasibility and acceptability of a telehealth diagnostic model deployed at an autism center in the southwestern United States to safely provide autism spectrum disorder (ASD) diagnostic evaluations to children, adolescents, and adults during the COVID‐19 pandemic. Participants included all clients for whom a telehealth diagnostic evaluation was scheduled at the diagnostic clinic (n = 121) over a 6‐month period. Of 121 scheduled clients, 102 (84%) completed the telehealth evaluation. A diagnostic determination was made for 91% of clients (93 out of 102) using only telehealth procedures. Nine participants (two females; ages 3 to 11 years) required an in‐person evaluation. Responses from psychologist and parent acceptability surveys indicated the model was acceptable for most clients. Psychologist ratings suggested that telehealth modalities used in the current study may be less acceptable for evaluating school‐aged children with subtle presentations compared to children in the early developmental period, adolescents, and adults. Parents of females reported higher acceptability than parents of males. Findings contribute to the small but growing literature on feasibility and acceptability of telehealth evaluations for ASD and have implications for improving access to care during and after the COVID‐19 pandemic. Lay Summary This study described telehealth methods for evaluating children, adolescents, and adults for autism spectrum disorder. Telehealth methods were generally acceptable to psychologists conducting the evaluations and parents of diagnostic clients. Psychologists reported the methods to be less acceptable for school‐aged children and parents of males found the methods less acceptable than parents of females. The telehealth methods described may help to increase access to diagnostic professionals and reduce wait times for evaluations during and after the COVID‐19 pandemic.
