Research on the implications of varying measurement strategies for estimating levels and correlates of intimate partner violence (IPV) has been limited. This study explored measurement and correlates of IPV using a community sample of 168 couples who were expecting their first child. In line with prior research, couple agreement regarding the presence of violence was low, and maximum reported estimates revealed substantial IPV perpetrated by both expectant mothers and fathers. Different types of IPV scores predicted unique variance in mental health problems and couple relationship distress among both the whole sample and the subsamples who perpetrated any violence. Discussion focuses on the methodological and substantive implications of these findings for the study of IPV during the transition to parenthood
