Currently, there are no existing measures to screen for or diagnose Social (Pragmatic) Communication Disorder (SPCD). We conducted an exploratory factor analysis (EFA) of the Social Communication Disorder Screener (SCDS), a 14-item, parent-report measure based on the DSM-5 diagnostic criteria for SPCD. This EFA examined the internal consistency and factor structure of the SCDS for a sample of 500 parents of children, ages 5-18 years, representative of the U.S. census. Results yielded a correlated three-factor solution with good internal consistency reliability. Findings supported the presence of three subscale as well as the derivation of a total composite score reflecting overall verbal and non-verbal communication and limitations across contexts. Clinical and research implications are discussed.
