In the spring of 2020, autism intervention programs in Geneva, Switzerland, were forced to close during a state-mandated home confinement period, in the response to the beginning of the COVID-19 pandemic. Therapists from three programs were asked to move early, intensive intervention sessions to an online video-conferencing format, providing primarily remote parent-implemented intervention sessions over a two-month period. In this study, we assessed the participation and satisfaction of 45 families from diverse cultural and socio-economic backgrounds, with 43 young children on the autism spectrum, and 5 toddlers who were suspected of having autism, as they experienced intervention services via telehealth for the first time. We provided questionnaires, to both the parents and the therapists working with them. Parents, regardless of socioeconomic status or cultural background, were highly motivated and engaged to learn the intervention strategies, with most families reporting high levels of satisfaction with the intensive, remote parent coaching model. The majority of parents reported that they progressed more in their interaction skills with their child with the daily remote coaching sessions, compared to services they received prior to the pandemic. Additionally, parents reported a positive experience with a much higher frequency of coaching sessions than has previously been studied. In our monitoring of child developmental progress, we observed a pattern of continued significant improvement across domains, without any stagnation of progress during the telehealth period. Our findings support previous studies that have demonstrated the benefits of telehealth services for young families with children on the autism spectrum, and go further to demonstrate high levels of satisfaction and motivation with caregivers from diverse cultural and socio-economic backgrounds, when provided with a high frequency of remote parent-implemented intervention.
