This study secured evidence of the validity and reliability of the Mate Retention Inventory-Short Form (MRI-SF) in the Brazilian context. Participants were 212 individuals in a long-term, heterosexual, romantic relationship residing in Fortaleza, aged between 18 and 59 years (M = 26.3, SD = 7.5), mainly female (58.5%) and attending college (60.8%). The average duration of the romantic relationship was 59.3 months (SD = 63.8 months). Participants answered demographic questions and completed a Brazilian Portuguese translation of the MRI-SF, which presents 38 items that assess how often participants performed each mate retention act described. The results indicated a two-factor structure that explained 33.3% of the total variance. The results also indicated that men and women differentially use several mate retention tactics. These results are discussed in light of evolutionary hypotheses of mate selection, and we highlight limitations of the current research and identify important directions for future research.
