Parental mental illness Relatively little has been written about the effect of serious and persistent parental mental illness on child abuse, although many studies show that substantial proportions of mentally ill mothers are living away from their children.14 Much of the discussion about the effect of maternal mental illness on child abuse focuses on the poverty and homeless - ness of mothers who are mentally ill, as well as on the behavior problems of their children — all issues that are correlated with involvement with child welfare services.15 Jennifer Culhane and her colleagues followed a five - year birth cohort among women who had ever been homeless and found an elevated rate of involvement with child welfare services and a nearly seven - times - higher rate of having children placed into foster care.16 More direct evidence on the relationship between maternal mental illness and child abuse in the general population, however, is strikingly scarce, especially given the 23 percent rate of self - reported major depression in the previous twelve months among mothers involved with child welfare services, as shown in NSCAW.17
