abstract="PURPOSE: This study assessed the distribution of posttraumatic stress disorder (PTSD) symptoms and psychosis indicators among a large sample of individuals with a lifetime diagnosis of PTSD. The identification of a psychotic PTSD subtype was also predicted. METHOD: Using data from the National Comorbidity Survey a latent class analysis was conducted on the PTSD symptoms of intrusion, avoidance, and hyperarousal and the psychosis hallucination and delusion indicators. RESULTS: Results indicated four latent classes, two of which had relatively high probabilities of endorsing the hallucination and delusion indicators. These classes were associated with a broad range of traumatic experiences. One particular class had high probabilities of endorsing both the psychosis indicators and the PTSD symptoms and was associated with a broad range of comorbid psychiatric disorders. CONCLUSION: There was a candidate class that met the characteristics expected to be evident in a psychotic PTSD subtype.<p /> <p>Language: en</p>",
