This research investigated the interplay between self-control, trust, and intrusive behaviors in heterosexual relationships. While past work mainly focused on actor self-control, we additionally considered the role of partner self-control in both men’s and women’s tendency to show intrusive behaviors. Specifically, we hypothesized that a lack of self-control in the partner elicits intrusive behaviors through low levels of trust in the partner. We collected data from 104 couples and 52 individuals (N = 260, M_age = 35.11, SD_age = 10.77) via a crowd-working platform. Analysis using an Actor Partner Interdependence Mediation Model with a bootstrapping method showed that trust mediated the association between partner self-control and intrusive behaviors. Additionally, actor self-control had a marginal indirect effect on intrusive behaviors through trust. The results were consistent across both genders. This research revealed that low levels of either actor or partner self-control are risk factors for privacy invasion in romantic relationships.

这项研究调查了异性恋关系中自我控制、信任和侵入行为之间的相互作用。虽然过去的工作主要集中在演员的自我控制上，但我们还考虑了伴侣自我控制在男性和女性表现出侵入性行为倾向中的作用。具体来说，我们假设合作伙伴缺乏自我控制会通过对合作伙伴的低信任度引发侵入性行为。我们收集了 104 对夫妇和 52 个人的数据（N  = 260，M_年龄 = 35.11，SD_年龄 = 10.77）通过众包平台。使用带有引导方法的参与者合作伙伴相互依赖中介模型的分析表明，信任调节了合作伙伴自我控制和侵入行为之间的关联。此外，行为者的自我控制通过信任对侵入性行为具有边际间接影响。两种性别的结果都是一致的。这项研究表明，演员或伴侣的自我控制水平低是恋爱关系中侵犯隐私的危险因素。
