We investigated the relationship between Brazilian women’s reported reasons for pretending orgasm, their performance of mate retention behaviors, and their relationship satisfaction. Additionally, we secured evidence of the validity and reliability of a Brazilian-Portuguese adaptation of the Reasons to Pretend Orgasm Inventory (RPOI). Participants were 295 Brazilian women in a heterosexual relationship (M_age = 24.9 years, SD_age = 5.4 years). Participants completed a Brazilian-Portuguese adaptation of the Mate Retention Inventory-Short Form, and the translated RPOI (the Escala de Razões para Fingir Orgasmo; ERFO). The resulting 47-item ERFO represents well the original 63-item RPOI. The frequency with which Brazilian women pretend orgasm was negatively associated with their relationship satisfaction. Our sample size may not be sufficient to detect small effects. In addition, due to the exploratory nature of the study, the results should be interpreted with caution and future research may attempt to replicate these findings with larger samples and in other countries.

我们调查了巴西女性所报告的假装性高潮的原因、她们的伴侣保留行为表现以及她们的关系满意度之间的关系。此外，我们还获得了巴西-葡萄牙语改编的假装性高潮原因量表（RPOI）的有效性和可靠性的证据。参与者是 295 名处于异性关系中的巴西女性（M_年龄= 24.9 岁，SD_年龄= 5.4 岁）。参与者完成了巴西-葡萄牙语版本的伴侣保留量表简表以及翻译后的 RPOI（Escala de Razões para Fingir Orgasmo；ERFO）。生成的 47 项 ERFO 很好地代表了原始 63 项 RPOI。巴西女性假装高潮的频率与她们的关系满意度呈负相关。我们的样本量可能不足以检测微小的影响。此外，由于该研究的探索性，应谨慎解释结果，未来的研究可能会尝试用更大的样本和在其他国家复制这些发现。
