Empirical literature about same-gender domestic violence was relatively nonexistent until the past 20 years, and conducting research with this population about a sensitive topic remains a daunting endeavor. Existing studies reveal similarities between opposite- and same-gender domestic violence in prevalence, types of abuse, and various dynamics, as well as dispel myths and establish a theoretical basis on which to conduct future research. Differences are evident in areas such as help-seeking behaviors and correlates, thus demanding unique assessment and intervention strategies. This article presents further explanation of the latest research, recommendations for future studies, and effective as well as problematic methodological practices about same-gender domestic violence.
