Psychological intimate partner violence (IPV) perpetration is not limited to heterosexual relationships and can affect all genders and sexual orientations, including lesbians and bisexual women (LB) both in Denmark and Turkey. Internalized heterosexism might be one of the factors increasing the risk of LB's use of psychological IPV perpetration. However, it is still unclear how being LB in Turkey and Denmark interact in the internalized heterosexism and psychological IPV perpetration relationship. The current study, therefore, presents an investigation of (a) the prevalence of sexual orientation (LB) and country (Denmark and Turkey) differences in perpetrating psychological IPV and (b) the moderating roles of sexual orientation and country on the association between internalized heterosexism and psychological IPV perpetration. A sample of 449 LB from Denmark and Turkey completed the Lesbian Internalized Homophobia Scale and the Multidimensional Measure of Emotional Abuse Scale. The results of chi-square analyses indicated that LB from Turkey and bisexual women from both countries reported significantly higher psychological IPV perpetration. The results of moderation analyses revealed that country had direct effects on the use of psychological IPV perpetration. No moderation effects were found for both sexual orientation and country in three of the four types of psychological IPV perpetration. These findings suggest that LB are not an exception to the perpetration of IPV. Furthermore, the findings were discussed from the perspectives of intersectionality and minority stress.
