Exploratory structural equation modeling was conducted using individual item\u2010level data from the Diagnostic Interview for Social and Communication Disorders (DISCO). DISCO is a comprehensive semi\u2010structured interview used by clinicians to elicit information from caregivers about the individual's profile of development and behavior. Data from a sample of 226 individuals with a clinical diagnosis of autism spectrum disorder (ASD) (189 males;\n                      <jats:italic>M<\/jats:italic>\n                      <jats:sub>age<\/jats:sub>\n                      \u00a0= 11.82\u2009years, SD\n                      <jats:sub>age<\/jats:sub>\n                      \u00a0=\u00a07.87) were analyzed. The six\u2010factor structure provided the most optimal and interpretable fit (comparative fit index\u00a0=\u00a00.944, Tucker\u2013Lewis index\u00a0=\u00a00.923, root mean square error of approximation\u00a0=\u00a00.018). Derived factors were interpreted as repetitive motor behaviors (RMB), unusual sensory and object focused interests (USOI), sensory sensitivity (SS), insistence on sameness (IS), circumscribed interests (CI) and stereotyped language (SL). Age was significantly negatively associated with RMB, USOI and SL but not with SS, IS or CI factor scores. None of the factors were associated with sex. ASD individuals with intellectual disability (ID) had the highest RMB, USOI, SS and SL scores while those without ID had the highest IS and CI scores. Our findings provide preliminary evidence for the utility of the DISCO as a comprehensive measure of several distinct RRB domains in both research and clinical contexts. Importantly, the current investigation highlights crucial areas for measurement development.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Lay Summary<\/jats:title>\n                    <jats:p>The diagnostic Interview for Social and Communication Disorders (DISCO) is a detailed caregiver report clinical interview designed to capture a wide range of key features associated with autism spectrum disorder, including restricted and repetitive behaviors (RRB).
