This proof-of-concept study assessed the feasibility of implementing Prevent-Teach-Reinforce-for-Young-Children (PTR-YC) program to address challenging behaviors in children with autism within the context of public, specialized early intensive behavioral intervention (EIBI) services offered in community settings. Following a 2-day training and with brief weekly supervision meetings, children's EIBI educators acted as facilitators in 35 families' home environments. Small and moderate effect sizes were observed for children's behavioral outcomes and parenting stress. Recruitment and retention rates, implementation fidelity, as well as treatment acceptability from the perspective of participating parents and the organization attested to the feasibility and relevance of implementing and evaluating this program on a larger scale as part of a multi-center randomized controlled trial.
