Brianna Byllesby

My research primarily investigates posttraumatic stress disorder (PTSD), its construct validity, and psychological outcomes following trauma exposure. I am particularly interested in the comorbidity between PTSD and related diagnoses and how these relationships may be influenced by transdiagnostic development and maintenance factors. I also examine these transdiagnostic factors in the context of treatment as potential moderators or mechanisms of change in trauma-focused treatment.
