Measuring intimate partner violence (IPV): you may only get what you ask for

With the goal of understanding the true extent of intimate partner violence (IPV), researchers have put tremendous effort over the past 20 years developing, revising, and assessing IPV screening instruments. The enhancements made in IPV instrumentation reflect our improved understanding of the nature of IPV. Unfortunately, as is often the case with progress, we are presently at the stage where IPV researchers have an arsenal of multiple IPV screens that are, in some cases, slightly different, whereas in others, the differences are sizeable. This article explores the evolution and variation of a sample of IPV screens. To further progress in IPV research, we must make conscious decisions concerning the best tool for our individual research. Simultaneously, we must enhance our understanding of how these IPV screening instruments overlap so that comparisons of IPV prevalence or incidence across time and population are possible.
