Mate retention behaviors are designed to reduce the likelihood of partner infidelity and relationship withdrawal. We investigated the psychometric properties of the Persian translation of The Coalitional Mate Retention Inventory (CMRI) in Iran and explored the sex differences in the performance frequencies of these behaviors. Participants in a committed heterosexual romantic relationship (n = 508, 270 female and 238 male) were drawn from a community sample. Participants reported demographic information (including age, duration of relationship), the Persian translation of CMRI, and the Persian translation of the Mate Retention Inventory–Short Form. The results of the confirmatory factor analyses demonstrated a good fit of the CMRI seven-factor model and achieved good reliability for CMRI and its subscales. We further documented sex differences in the frequency with which coalitional mate retention behaviors were performed. The results revealed that CMRI is a valuable instrument for assessing mate retention across diverse cultures.

伴侣保留行为旨在减少伴侣不忠和关系退出的可能性。我们研究了伊朗联合伴侣保留量表（CMRI）的波斯语翻译的心理测量特性，并探讨了这些行为的表现频率的性别差异。具有忠诚异性恋关系的参与者（n = 508，其中 270 名女性和 238 名男性）是从社区样本中抽取的。参与者报告了人口统计信息（包括年龄、关系持续时间）、CMRI 的波斯语翻译以及配偶保留量表（简表）的波斯语翻译。验证性因素分析结果表明CMRI七因素模型拟合良好，CMRI及其子量表具有良好的信度。我们进一步记录了进行联盟配偶保留行为的频率的性别差异。结果表明，CMRI 是评估不同文化中的择偶保留的宝贵工具。
