In this training, clinicians learn about assessing autism spectrum disorder and personality disorders in adults, focusing on overlap, context, and diagnostic clarity.

Key insights:

  • Overlapping traits can mask key differences in social motivation, rigidity, and interpersonal patterns
  • Cultural and contextual factors can shift how symptoms present and are interpreted
  • Structured assessment tools help clarify diagnosis, especially in complex or comorbid cases

About This Training

Autism Spectrum Disorder (ASD) and Personality Disorders (PD’s) are both complex diagnostic presentations that have some symptom overlap, making differentiating the two in undiagnosed adults challenging. This training will present the latest research on the intersection of these two disorders, similarities and differences in symptom presentations, and how to best approach psychological evaluations for them. There are no known risks to attendees or patients. As with all clinical interventions, attendees should be careful about utilizing assessment measures without appropriate training and supervision.

Learning Objectives: 

  1. Describe similarities and differences in symptom presentations between ASD and at least two different personality disorders.

  2. Identify two ways different cultural and contextual variables can impact the presentation of ASD and personality disorders.

  3. List at least 3 testing measures that are useful for adding diagnostic clarity in the case of suspected comorbid ASD and personality disorder.
