Abstract

Infidelity has been widely researched; however, few studies have analyzed its behavioral patterns holistically using a person-centered approach. This study, with a sample of 400 young adults (M_age = 25.28; SD = 7.24), identified patterns of unfaithful behavior by using latent class analysis to classify subgroups with distinct patterns. The 20-item Likert-scale Multidimensional Infidelity Inventory-S (MII-S) was used to assess sexual and emotional infidelity. The results indicated four latent classes: infidelity (15.7%), sexual desire (14.4%), emotional interest (27.2%), and fidelity (42.5%). In addition, age and sex were significantly related to class membership. On the other hand, men were more likely to belong to the sexual desire class and women to the emotional interest and fidelity classes. For sexual orientation or relationship duration, there were no significant differences. Implications for clinical practice and research are discussed

在秘鲁年轻人样本中探索不忠行为模式：一个潜在阶层分析

人们对不忠进行了广泛的研究；然而，很少有研究使用以人为本的方法对其行为模式进行全面分析。本研究以400名年轻人为样本（Mage = 25.28; SD = 7.24），通过潜在类分析对具有不同模式的亚组进行分类，确定了不忠行为的模式。本研究采用李克特多维出轨量表（MII-S）来评估性出轨和情感出轨。结果显示了四个潜在类别：不忠（15.7%）、性欲（14.4%）、情感兴趣（27.2%）和忠诚（42.5%）。此外，年龄和性别与班级成员显著相关。另一方面，男性更有可能属于性欲阶层，而女性更有可能属于情感兴趣和忠诚阶层。在性取向和关系持续时间方面，没有显著差异。对临床实践和研究的意义进行了讨论
