Learner Objectives

This session will help participants…

  1. explain the role of IQ on ASD symptom expression and timing of identification for males and females.
  2. describe sex differences in ASD presentation as measured by the ADOS and ADI-R.
  3. describe sex differences in timing of ASD assessment and diagnosis.


Identifying individuals with ASD is complex due to the continuum of behavioral topographies and symptom severity differences. This study will describe how sex and IQ impact diagnostic scores on the ADOS and ADI-R and timing of diagnosis. Attendees will better understand sex differences and the role of IQ in ASD diagnosis. Recommendations will be provided on how practitioners can improve early identification of ASD by understanding patterns of ASD characteristics by sex and IQ.
