Data for Clinical Correlates of Irritability, Anger, Hostility, and Aggression in Adult Posttraumatic Stress Disorder

After adjustment for trauma exposure and PTSD symptoms, irritability was associated with almost all psychopathology and suicidal behaviors, however, anger, hostility, and aggression were sparsely related to some psychopathology or suicidal behaviors. Particularly, anger was only related to ADHD and insomnia. Latent profile analysis based on PTSD, irritability, anger, hostility, and aggression indicated two discrete subgroups: the high severity group (33.8%) and the low severity group (66.2%), with high severity group reporting higher rates of comorbidity and suicidal behaviors.

Conclusions: The findings support irritability, aggression, anger, and hostility as separate constructs; moreover, irritability, anger, and aggression should be independently measured in PTSD. Our findings also suggest the significance of irritability as a separate hallmark of PTSD and the need to incorporate PTSD dimensions.
