Measuring Social Motivation in Autism Spectrum Disorder: Development of the Social Motivation Interview.

Social motivation in individuals with ASD is inferred from the observation of overt behaviors and neurological correlates. Motivation, however, can be distinguishable from overt behavior and neurologic reactivity. Nevertheless, few studies have examined the cognitive processes that may influence goal-directed tasks involved in social interaction. This study addressed this conceptual need by developing a novel interview. The social motivation interview (SMI) assesses for internal cognitions as they relate to social motivation by evaluating social desire, interest, and behaviors in eighteen children with ASD (M years = 12.84). Pilot testing suggested feasibility of administration, user satisfaction, and promising psychometric properties. Future examination of the SMI in large-scale field testing is warranted.
