Substance abuse tied to aggression in mentally ill

Although some may believe that improving symptoms of mental illness is more likely to lessen the risk for future episodes of violence, a new study from the University at Buffalo Research Institute on Addictions suggests that reducing substance abuse has a greater influence in reducing violent acts by patients with severe mental illness “We were surprised to find that the severity of the patient’s psychiatric symptoms was not the primary factor in predicting later aggression,” Clara Bradizza, senior research scientist at the institute, and co-author of the study, said in a news release. “Rather, the patient’s substance abuse was the factor most closely associated with future aggression.” Institute officials stressed that the vast majority of people with mental illness do not engage in violent acts. But they said the risk of violence is greater among the severely mentally ill than the general population, and the connection between severe mental illness, substance abuse and aggression is a significant concern for community safety, treatment programs and public policy. “Our findings suggest that treatment attendance is very important for these individuals and treatment programs should include interventions that are likely to decrease substance abuse, as this may provide the additional benefit of reducing the risk of later aggression among dual-diagnosis patients,” Bradizza said. “This not only improves the lives of affected individuals and their families, but also provides a safer environment for society as a whole.” The study, funded by a grant from the National Institute on Alcohol Abuse and Alcoholism, followed nearly 300 patients over a six-month period following admission to an outpatient dual-diagnosis treatment program that provided both substance abuse and mental illness treatment. The results appear in the current online edition of the Journal of Substance Abuse Treatment. The other study co-authors are researchers Yue Zhuo of St. John’s University and Stephen A.
