Youth with Intellectual and Developmental Disabilities (IDD) represent about 17% of the population and these youth are at heightened risk of exposure to potentially traumatic events (PTEs). Given the association between developmental level and resilient coping in the face of adversity, youth with IDD may experience heightened trauma responses compared to neurotypical youth. Despite this vulnerability, youth with IDD are underrepresented in the trauma intervention literature. This case study presents the treatment of a 20-year-old transitional age youth with IDD and post-traumatic stress symptoms (PTSS) using Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) combined with visual supports to augment communication. Findings from this case report documented (a) caregiver reported improvement in PTSS, anxiety, and depressive symptoms, (b) caregiver satisfaction with intervention, (c) and maintenance of gains at 1-month follow-up.
