Abstract
The present study examined the relationship between relational quality and three different types of jealousyreactive, anxious and possessive jealousy. The sample consisted of 76 gay men, 79 lesbians, 70 heterosexual women and 70 heterosexual men. Findings show that different types of jealousy affect relationship quality differently and do so differently for homosexuals and heterosexuals. Among heterosexuals and especially gay menbut not among lesbiansanxious jealousy was negatively related to relationship quality. In contrast, among heterosexualsbut not among gay men or lesbiansreactive jealousy was positively related to relationship quality. The present study shows that distinguishing between different types of jealousy is necessary to entangle the diverse effects of jealousy on the quality of homosexual and heterosexual relationships.
