Abstract

The authors of the included articles provide cogent summaries of their findings, recommendations, and needed future directions. A few key themes in this introduction: 1. Underlying trauma may trigger and perpetuate psychosis. 2. Transdiagnostic risk factors associated with psychosis and PTSD. 3. Psychosis, PTSD, and dissociation are overlapping but distinct constructs. 4. Both Criterion A traumas and non-Criterion A events contribute to both PTSD and psychosis. The included articles have paved the way for further research in this area. While key transdiagnostic risk factors were identified, it is important to elucidate individual differences and develop a nuanced understanding of how specific transdiagnostic risk factors influence the etiology of PTSD and psychosis.
