The BOSCC (Brief Observation of Social Communication Change) is a treatment response measure of social communication behaviors and other behaviors associated with an autism spectrum disorder (ASD). Development of the BOSCC evolved through the expansion of codes from the ADOS-2 in order to capture more nuanced variation in behaviors. BOSCC coding can be applied to standard play contexts between a child/individual and an adult (e.g., parent, clinician) in a home or clinic setting.
