Comparing the Impact of Differing Preschool Autism Interventions on Parents in Two Canadian Provinces.

Early Intensive Behavioural Intervention (EIBI) is effective for preschoolers with autism spectrum disorder (ASD). Parental measures are rarely included in EIBI effectiveness studies, yet parental distress and lower self-efficacy are associated with poorer child outcomes. Parents of preschoolers with ASD (N = 485) were surveyed at baseline (T1), one-year post-intervention (T2), and school entry (T3) about family distress/crisis, parental self-efficacy, and satisfaction with services in two Canadian provinces. Family distress/crisis decreased and parental self-efficacy increased from T1 to T2. Increases in self-efficacy were largely maintained at T3. Parents were highly satisfied with services. Greater satisfaction for those residing in the province utilizing a parent-coaching model suggests that parent involvement is associated with positive parent outcomes.
