This preliminary single-arm pre-post interventional study was designed to evaluate the acceptability and preliminary clinical outcomes of an 8-week online group-based parent-mediated intervention (OYNA) for parents of young autistic children. Mothers and fathers independently completed assessments of their child's social communication skills and their own psychological distress at baseline and immediately after the intervention. The study was designed to examine pre-post changes in children's social communication and parental psychological distress and to compare maternal and paternal assessments at both time points. Parent satisfaction with the program was assessed following the intervention, and demographic and clinical factors associated with parent satisfaction were also examined.
