Treated Mental Illness and the Risk of Child Abuse Perpetration

Despite a limited empirical literature, parental mental illness is often cited as a major risk factor for violence against children. However, mental illness that is adequately treated would not be expected to lead to increased violence risk. This study compared incidents of violence toward children perpetrated by parents who were newly discharged from inpatient psychiatric treatment with violence perpetrated by other parents in the same communities to determine whether parents with treated mental illness had an elevated risk of child abuse perpetration.

A secondary analysis of data from the MacArthur Violence Risk Assessment Study was conducted. Violence toward children reported by parents and by collateral informants at the initial ten-week follow-up interview was analyzed for two groups: study participants discharged from inpatient psychiatric facilities and parents in the community matched by neighborhood.

Of the 416 parents in the participant group, 20 (5%) committed violence toward a child in the ten weeks after discharge, compared with 41 (14%) of the 299 parents in the comparison group. In the participant group, diagnostic categories of parents who committed violence toward a child were as follows: serious mental illness only (8% of whom were violent), substance use disorder only (3%), both serious mental illness and substance use disorder (4%), and another issue (7%).

This study found that parents with treated serious mental illness were not at higher risk than other parents in their community of perpetrating violence toward children. Parents who were admitted to an acute psychiatric facility and treated appeared to be at lower risk of being violent toward children than other parents in their community.
