Commentary: Insights into the Development of the Brief Observation of Social Communication Change (BOSCC).

A recent review of early behavioral interventions for autism spectrum disorder6 suggested that many intervention trials are of “low quality”18, in part due to the limited ability of researchers to interpret and evaluate efficacy. Most early interventions focus on teaching social communication skills, core deficits in children with ASD. However, measures currently used to quantify social communication skills, such as the Autism Diagnostic Observation Schedule (ADOS-2)14 were developed to be primarily diagnostic and lack the sensitivity to capture subtle changes over relatively brief periods2,4. The field of ASD intervention research needs measures that can identify subtle changes in core ASD symptoms.
