Domestic violence more likely for mentally ill

Compared to those without mental illness, women with depressive disorders were about 2.5 times more likely to have experienced domestic violence, while women with anxiety disorders were more than 3.5 times more likely, and those with post-traumatic stress disorder were about seven times more likely. 

Mental health disorders were associated with increased likelihood of being a victim of domestic violence in men too, but the prevalence rates were lower.
