Effectiveness of an online-delivered parent-mediated intervention for the improvement of social skills of children with autism

Abstract

Individuals with Autism Spectrum Disorder (ASD) show social communication difficulties, a common symptom alongside behavioural issues. These difficulties may affect both their social and academic inclusion when they do not receive proper support. The current study attempts to examine the effects of a parent-mediated intervention that was delivered online to improve the social communication skills of a sample of 12 young children with ASD (intervention group = 6; control group = 6). The intervention programme consisted of 10 sessions based on multiple strategies, including social stories, 3D-video modelling and video self-modelling, with the use of prompting, fading and social reinforcement, targeting different social communication skills. A quasi-experimental method was used based on pre- and post-intervention assessment and follow-up to evaluate the effects of the intervention. The results showed that participants in the intervention group showed significant improvements over the control group in sociability and speech/language/communications domains, and there was an improvement in the total Autism Treatment Evaluation Checklist (ATEC). Also, parents demonstrated high fidelity in the implementation and high satisfaction with the intervention programme. The limitations and future implications of the study are discussed.
