In response to a dearth of empirical literature concerning the mechanisms underlying female same-sex intimate partner violence (FSSIPV) perpetration, the purpose of this research is to inform intimate partner violence intervention and prevention strategies specific to sexual minority women. The research responds in particular, this research aims to inform a working intersectional model predicting FSSIPV perpetration, and to evaluate the face validity and construct coverage of existing survey measures related to gender, minority stress, and violence. Fourteen lesbian, gay, bisexual, transgender, and queer women recruited from the greater Portland, Oregon area participated in a series of in-depth, semi-structured, open-ended one-on-one and focus group interviews. Participant recruitment involved a combination of purposive and convenience sampling methods aided by the involvement of multiple community partners working in violence and education related fields. Interview and focus group questions addressed participants' experiences with gender role stress and minority stress. Grounded theory analysis of participants' narrative responses informed the coverage and relevance of constructs in a working intersectional model predicting women's use of violence in their same-gender intimate relationships. In particular, findings indicate that sexual minority women's experiences of gender role stress and minority stress, particularly in combination, were especially influential on their identities. Sexual minority women's experiences with minority stressors were not confined to minority stressors specific to their gender identities and sexual orientations, but intersected with minority stressors related to race and class as well. These findings support an intersectional and contextually-minded approach to IPV intervention and prevention strategies.
