Which statement about family dynamics and child maltreatment is supported by research?

Research has consistently shown that a high percentage of parents who maltreat their children have histories of abuse themselves. This does not mean that all parents who were abused as children will go on to abuse their own children. Similarly, the statement that parents who do not work are more likely to abuse their children is not supported by research. In fact, many working parents have strong support systems and are able to provide a safe and nurturing environment for their children. Additionally, while day care can be a risk factor for child maltreatment, it is not the only factor and does not mean that all children who do not attend day care will be maltreated. Therefore, the most supported statement by research is that a high percentage of parents who maltreat their children have histories of abuse.
