Researchers from England, in a study of 458 first episodes of psychosis, find that delusional beliefs coupled with elation, fear, anxiety are not associated with violence. Delusional beliefs in the context of depression are associated with less violence. “Anger due to delusions appeared to constitute the main drive to serious violence,” said the authors of the study, published in JAMA Psychiatry.
