SUSAN B. S ORENSON AND K RISTIE A. THOMAS University of Pennsylvania Views of Intimate Partner Violence in Same- Opposite-Sex Relationships Attitudes toward same-sex intimate relationships and intimate partner violence (IPV) are changing. Little research, however, has examined norms about IPV in same-sex relationships. Using a frac- tional factorial (experimental vignette) design, we conducted random-digit-dialed interviews in four languages with 3,679 community-residing adults. Multivariate analyses of responses to 14,734 vi- gnettes suggest thatIPV against gay male, les- bian, and heterosexual women is more likely than thatagainst heterosexual men to be considered illegal and that it should be illegal, police called, and a stay-away order issued. Regardless of gen- der and sexual orientation, the type of abuse and whether a weapon was displayed are the stron- gestpredictors of respondents’ judgments about whether a behavior is illegal and merits a range of societal interventions. Since its inception asa topic of scholarly inquiry,the definition of what constitutes vio- lence against an intimate has evolved from phys- ical assaultaloneto includesexualassault, psychologicalmaltreatment, and stalking. Moreover, the term ‘‘domestic violence,’’ which is widely used and largely associated with mar- ried heterosexual couples, has been supplanted in some quarters by the term ‘‘intimate partner violence’’ (IPV) so as to explicitly include peo- ple who are in nonmarital relationships, for example, dating adolescents, divorced women and lesbians and gay men. As views of violence in intimate relationship are changing, so are perceptions of same-sex relationships. Concomitant with more positive attitudes toward gay men and lesbians and th sexualbehaviorduringthe pastgeneration (Hicks & Lee, 2006; Treas, 2002), national pol document dramatically increased support of civil unions, inheritance rights, and Social Sec rity benefits for gay male and lesbian partners (Brewer& Wilcox, 2005).There are limits, however. A majority of Americans believe tha same-sex marriage undermines traditional fam ily values and do not support same-sex marria (Brewer& Wilcox; Schmitt,Lehmiller,& Walsh,2007).And Americans remain divided on the issue of whether children should be ad ted by same-sex couples (Pew Research Cente 2006). Those who hold more negative views about gay men and lesbians are those with less form education (Ohlander, Batalova, & Treas, 2005 higher religiosity (Hicks & Lee, 2006), stronge adherence to traditional male and female roles (Hicks & Lee), and little personal contact with gay men and lesbians (Herek & Glunt, 1993). Antigay sentiment is believed to be strong in minority communities (Diaz, Ayala, Bein, Henne,& Marin, 2001;Mays & Cochran, 2001; Wilson & Yoshikawa, 2004); nonetheles some ofthese same groups favorprotections against discrimination on the basis of sexual o entation (Lewis, 2003). Many of the participan in the present investigation are immigrants, so it may be useful to note that acceptance of 3815 Walnut Street, Philadelphia, PA 19104 (sorenson@ sp2.upenn.edu).
