【摘要】恋爱伴侣同居是浪漫关系发展中的一个常规阶段，人们选择同居的原因各不相同。鲜有研究探讨同居原因是否会对长期的关系运作产生影响。本研究考察了三种常见的同居原因（即：为了共度时光、为了考验关系、出于便利）与随时间推移的关系结果（关系运作状况及关系破裂）之间的关联。在一项为期5年（2007年至2012年）的纵向研究中，研究人员对处于异性恋关系并与伴侣同居的成年人（N=485）进行了调查，收集了他们同居的原因（数据采集时间最接近同居发生之时）以及关系状态和运作状况（涵盖多达11个调查波次）的相关信息。结果显示，越是出于“共度时光”这一原因而同居，同居后的整体关系运作状况越好；越是出于“考验关系”这一原因而同居，同居后的整体关系运作状况越差，且关系破裂的可能性越高；出于“便利”原因同居则无法预测同居后的关系结果。这三种原因均未能预测关系运作状况随时间变化的轨迹（即变化斜率）；相反，无论同居原因如何，人们在同居后的关系运作轨迹呈现出相似的模式，尽管其起点水平（即同居时的初始水平）存在差异。同居原因似乎反映了同居前的关系质量，而非影响同居后的关系发展轨迹。研究结果强调了伴侣在决定同居时探讨各自同居动机的重要性。

[Abstract] Romantic couples moving in together (i.e., cohabitation) is a normative stage of romantic relationships, and people report different reasons for moving in together. Few studies have examined whether reasons for cohabitation have implications for relationship functioning over time. This study investigated how three commonly endorsed reasons for cohabitation (i.e., to spend time together, to test the relationship, and out of convenience) were associated with relationship outcomes (relationship functioning and dissolution) over time. In a 5-year longitudinal study (from 2007 to 2012), adults (N = 485) who were in opposite-sex relationships and moved in with their partner were surveyed on their reasons for cohabitation (closest in time to moving in together) and their relationship status and functioning (in up to 11 waves of surveys). Results showed that greater endorsement of cohabiting to spend time together predicted better overall relationship functioning after cohabiting. Greater endorsement of testing the relationship predicted worse overall relationship functioning and a higher likelihood of relationship dissolution after cohabiting. Moving in together out of convenience did not predict postcohabitation relationship outcomes. The three reasons did not predict overtime trajectories (i.e., slopes) of relationship functioning. Instead, people showed similar trajectories of relationship functioning after moving in together regardless of their reasons for cohabitation, albeit at different levels that were differentiated at the time of moving in together. Reasons for cohabitation appear to reflect preexisting relationship quality, instead of impacting its postcohabitation trajectories. Findings highlight the importance of couples discussing their reasons for cohabitation when making decisions about moving in together.
