Rooted in Huston's (2000) model of adjustment in romantic relationships, the present study examined differences in individual and relationship characteristics and the predictive value of those characteristics for relationship satisfaction, regarding four groups of participants, based on gender and sexual orientation. The sample included a total of 100 heterosexual couples and 50 male and female homosexual couples each. Of the individual characteristics, need for affect achieves significant both actor and partner effects on relationship satisfaction in all subsamples, except for heterosexual women. A personal expression of love achieves both actor and partner effects on relationship satisfaction for heterosexual and homosexual men. The partner's expression of love (actor effect) on relationship satisfaction was registered in all groups, except for homosexual men. The present study offers the possibility of integrating knowledge of the differences between heterosexual and homosexual couples in the context of the model of adjustment in romantic relationships.

同性恋和异性恋夫妇的关系满意度：二元模型

根植于休斯顿（2000）的恋爱关系调整模型中，本研究根据性别和性取向，针对四组参与者检查了个体和关系特征的差异以及这些特征对关系满意度的预测价值。样本共包括100对异性恋夫妇，以及50对男女异性恋夫妇。在个体特征中，除了异性恋女性外，在所有子样本中，对情感的需求都对演员和伴侣的关系满意度产生了重要影响。爱的个人表达在异性恋和同性恋男人的关系满意度上同时获得演员和伴侣的影响。在所有组中都记录了伴侣对关系满意度的爱意表达（演员效应），除了同性恋男人。本研究提供了在浪漫关系调整模型的背景下整合关于异性恋和同性恋夫妇之间差异的知识的可能性。
