This commentary considers Hamby’s (2016) use of a qualifier that specifies “Not including horseplay or joking around” when assessing intimate partner violence (IPV) victimization. We highlight some of the thinking behind the use of this qualifier, review findings of other studies that have used similar qualifiers, describe and discuss Hamby’s methods, and speculate on how the qualifier might affect measurement. We then offer several suggestions for additional research to improve measurement of IPV. These include addressing incremental validity, reducing measurement error, understanding how new or revised measures operate to improve prediction, and evaluating differential item and test functioning.
