					NEW FACTORS IDENTIFIED FOR PREDICTING VIOLENCE IN SCHIZOPHRENIA A study of adults with schizophrenia showed that symptoms of losing contact with reality, such as delusions and hallucinations, increased the odds of serious violence nearly threefold. The odds were only about one-fourth as high in patients with symptoms of reduced emotions and behaviors, such as flat facial expression, social withdrawal, and infrequent speaking. Results of the study, which was conducted in patients in real-world community settings as part of the NIMH-funded Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE), were published in the May 2006 issue of the "Archives of General Psychiatry." Jeffrey A. Lieberman, M.D., of Columbia University, was the principal investigator. Overall, the amount of violence committed by people with schizophrenia is small, and only 1 percent of the U.S. population has schizophrenia. Of the 1,140 participants in this analysis, 80.9 percent reported no violence, while 3.6 percent reported engaging in serious violence in the past six months. Serious violence was defined as assault resulting in injury, use of a lethal weapon, or sexual assault. During the same period, 15.5 percent of participants reported engaging in minor violence, such as simple assault without injury or weapon. By comparison, about 2 percent of the general population without psychiatric disorder engages in any violent behavior in a oneyear period, according to the NIMH-funded Epidemiologic Catchment Area Study.
