The "Medea complex" among men: the instrumental abuse of children to injure wives.

It has been previously documented that wife and child abuse often co-occur. The present study tested competing hypotheses about the reasons for this co-occurrence, specifically trait versus instrumental theories of aggression within families. Three commonly cited catalysts (unemployment, drinking, and life-stress events) for men's abuse of family members were analyzed to determine whether they equally predict partner or child abuse. Interviews were conducted with 363 women and children about spousal and paternal abuse, and women were interviewed about sociodemographics and the stressors described above. Families were oversampled for the presence of spousal violence. Logistic regressions revealed that heavy drinking (log-odds ratio 4.86) and life stress events (log-odds ratio 1.6) predicted men's abuse of their partners. These risk factors were unrelated to child abuse. Wife battering, however, placed children at heightened risk (log-odds ratio = 2.77). Children of battered women stood a 42% chance of receiving escalated abuse from their fathers. It is proposed that men's abuse of children is in many instances instrumental in order to coerce or retaliate against women, echoing the Greek myth of Medea who killed her own children to spite their father.
