My information was from another study, but the results were essentially the same. Women abused the kids at a 2/1 ratio compared to men (40/17.6, or 2.3 to 1 in your study). Both parents were involved in the child abuse in a significant number of cases (almost 1 out of 5 in both studies). In your study, nearly 40% were excluded due to incomplete information, which is too bad, as it makes the percentages potentally inacurate. As your study shows, only 20% reported abuse in a married home.
