12-Month Prevalence,Trends, Gender Differences,and the Impact of Mental Health Services on Intimate Partner Violence Perpetration Among Discharged Psychiatric Inpatients

Minimal research has examined partner violence committed by individuals with severe mental illness. This study examined rates of IPV in the first year post-discharge from psychiatric hospitalization, trends over time, gender differences, and the impact of follow-up mental health services. One in five (20.3 %) patients committed at least one act of IPV in the first year. Whereas women were more than twice as likely to perpetrate IPV, men were nearly twice as likely to be violent toward non-family members. Risk of IPV was highest immediately post-discharge and decreased over time, with the sharpest decline after 20 weeks in the community. Mental health treatment was associated with a 40 % decrease and medication non-adherence a 50 % increase in risk for IPV. Partner violence is a prevalent concern among discharged psychiatric patients, and these findings suggest that coordinated risk management efforts should focus on the time immediately following hospital discharge.
