9 in 10 men want their doctors to ask about domestic violence
University of Wisconsin-Madison

A nationally representative survey of young men finds that 90 percent believe their doctors should ask whether they have perpetrated or experienced domestic violence — but only 13 percent have ever been asked. The large gap suggests that physicians have an opportunity to begin more conversations about domestic violence and potentially intervene, says Tova Walsh, a professor of social work at the University of Wisconsin–Madison, who led the study.
