People who lack quality relationships are more likely to engage in infidelity but how relationship quality is associated with infidelity is less clear. One psychological mechanism that might help to explain these associations is sociosexuality. Here, we tested two models in which we assessed whether overall sociosexuality and sociosexuality subscales (i.e., attitude, behavior, desire) explain how relationship quality is related to infidelity intentions by sampling individuals in exclusive relationships (N = 219). We found that individuals with lower relationship quality had more unrestricted sexual orientation, which in turn predicted a greater intention toward infidelity. In addition, lower quality relationships were associated with greater intentions toward infidelity through behavior and desire, but not attitude dimensions of sociosexuality.

缺乏优质关系的人更有可能从事不忠行为，但关系质量如何与不忠相关联尚不清楚。可能有助于解释这些关联的一种心理机制是社会性。在这里，我们测试了两个模型，其中我们评估了总体社会性别和社会性别分量表（即态度，行为，欲望）是否通过对排他性关系中的个体进行抽样来说明关系质量与不忠意图之间的关系（N= 219）。我们发现，关系质量较低的人的性取向更为不受限制，这反过来又预示了对不忠的更大意图。此外，较低质量的关系与通过行为和欲望导致更大的不忠行为相关，而与社会性的态度维度无关。
