This correlational study is conducted on women living in Tehran. Additionally, 150 people were selected by convenience sampling from different parts of Tehran, who completed questionnaires on marital instability, sex roles and orientation in a sexual relationship. The results showed that orientation in a sexual relationship, except for communal orientation in the role of femininity in women, has a moderating role between sex roles and marital instability. In all cases, greater communal orientation in a sexual relationship reduces the instability of marriage in women. Also, a higher exchange orientation in a sexual relationship increases the instability of marriage in women. Additionally, greater demand in a sexual relationship, except when masculinity is high in women, heightens marital instability in women. In women with higher levels of communal exchange and demand orientation in a sexual relationship, increased sex roles (masculinity or femininity) reduce instability, and in women with lower levels of demand and exchange in sex, increased sex roles (masculinity or femininity) do not change the degree of marital instability. Based on this, the findings of this study can be used to monitor and increase the stability of marriage in Iranian society.</span></span></span></div> Marital instability, Sex roles, Communal orientation in a sexual relationship, Demand orientation in a sexual relationship, Exchange orientation in a sexual relationship, women 277 289 http://ieepj.hormozgan.ac.ir/browse.php?a_code=A-10-505-1&slc_lang=en&sid=1 Parisa Zamanian پریسا زمانیان Parisa.zamanian90@gmail.com 10031947532846006033 10031947532846006033 Yes Master of Family Clinical Psychology, Family Research Institute, Shahid Beheshti University, Tehran, Iran کارشناس ارشد روانشناسی بالینی خانواده، پژوهشکده خانواده، دانشگاه شهید بهشتی، تهران، ایران Ali Zadehmohammadi علی زاده ‌‌محمدی dr_zadeh@sbu.ac.ir 10031947532846006034 10031947532846006034 No Associate Professor, Clinical Psychology, Family Research Institute, Shahid Beheshti University, Iran دانشیار، روانشناسی بالینی پژوهشکده خانواده دانشگاه شهید بهشتی Leili Panaghi لیلی پناغی l_panaghi@sbu.ac.ir 10031947532846006035 10031947532846006035 No Ph.D. in Social Medicine, Associate Professor, Family Research Institute, Shahid Beheshti University, Tehran, Iran دکترای تخصصی پزشکی اجتماعی، دانشیار گروه روانشناسی، پژوهشکده خانواده، دانشگاه شهید بهشتی، تهران، ایران
