Mutuality, severity, and chronicity of violence by Father-Only, Mother-Only, and mutually violent parents as reported by university students in 15 nations.

This article aims to provide a more complete description of the violence between parents experienced by children than is usual in research and to suggest the practicality and importance of doing so. It presents results on the percent of parents in each of three Dyadic Types: Father-Only (the father assaulted the mother and the mother did not assault), Mother-Only (mother assaulted and the father did not assault), and Both-Assault; and on differences between these three types in the chronicity and severity of assaults. Questionnaires were completed by convenience samples of university students in 15 nations (N=11,408).
