People are more likely to seek out romantic partners who are politically similar to themselves. Nonetheless, romantic partners who disagree politically do exist. This study examines the influence of political (dis)similarity in romantic relationships on both political participation and relationship satisfaction. We found that (1) people in politically similar romantic relationships are more satisfied in their relationships and more politically participative than those who are in dissimilar relationships, (2) discussion expressiveness mediates the relationships between political similarity and satisfaction, (3) discussion frequency and expressiveness mediate the relationship between political similarity and participation, and (4) whereas political conflict intensity mediates the relationship between political similarity and satisfaction, it does not affect participation. Findings indicate that the quality of discussion and conflict, not merely their occurrence, help explain the political and relational results of political (dis)similarity within romantic relationships.

爱情与政治：政治上（不）相似的浪漫关系对政治参与和关系满意度的影响

人们更有可能寻找在政治上与自己相似的浪漫伴侣。尽管如此，在政治上存在分歧的浪漫伴侣确实存在。本研究考察了浪漫关系中政治（不）相似性对政治参与和关系满意度的影响。我们发现（1）政治相似的浪漫关系中的人比处于不同关系中的人对他们的关系更满意，政治参与度更高，（2）讨论表达能力在政治相似性和满意度之间的关系中起中介作用，（3）讨论频率和表达性在政治相似性和参与之间的关系中起中介作用，并且（4）而政治冲突强度在政治相似性和满意度之间的关系中起中介作用，它不影响参与。研究结果表明，讨论和冲突的质量，而不仅仅是它们的发生，有助于解释浪漫关系中政治（不）相似性的政治和关系结果。
