Abstract Prior work proposed a shortened version of the Social Responsiveness Scale (SRS), a commonly used quantitative measure of social communication traits. We used data from 3031 participants (including 190 ASD cases) from the Environmental Influences on Child Health Outcomes (ECHO) Program to compare distributional properties and criterion validity of 16-item “short” to 65-item “full” SRS scores. Results demonstrated highly overlapping distributions of short and full scores. Both scores separated case from non-case individuals by approximately two standard deviations. ASD prediction was nearly identical for short and full scores (area under the curve values of 0.87, 0.86 respectively). Findings support comparability of shortened and full scores, suggesting opportunities to increase efficiency. Future work should confirm additional psychometric properties of short scores. Keywords Autism spectrum disorder · Social Responsiveness Scale · Quantitative traits · Social communication Deficits in social communication, and the presence of restricted, repetitive behaviors or interests, are the hallmarks of an autism spectrum disorder (ASD) diagnosis. Although ASD is a categorical diagnosis, the continuum of the ASDrelated phenotype extends into the general population (Constantino and Todd 2005; Robinson et al. 2016). The study of ASD-related traits as a continuous distribution in population samples therefore holds promise for more fully gauging the Electronic supplementary material The online version of this article (https://doi.org/10.1007/s10803-020-04667-1) contains supplementary material, which is available to authorized users.
