What we can say about the definition of “family violence” is that it is gender-neutral. It would apply to intimate partner violence, which can happen between different genders or the same gender, but it also includes violence that can happen to children. It's a broad definition and it would include violence committed against whatever gender, as long as it falls within the broad definition of conduct that's covered by that definition.
