Relational mobility is a socio-ecological construct quantifying how much freedom and opportunity a society affords individuals to choose and dispose of interpersonal relationships. Past research has confirmed that relational mobility varies across nations, but no large-scale study has examined the degree to which relational mobility may vary within a single nation. We report two studies (Study 1, N = 647; Study 2, N = 7343) exploring within-country similarity or variability in relational mobility across all 27 states and five geo-socio-political regions in the continent-size country of Brazil. Results confirmed the measurement equivalence of the Relational Mobility Scale across respondents from all Brazilian states. Notably, relational mobility scores were uniform across Brazilian regions and states, indicating a common national culture regarding the amount of opportunities Brazilians have in selecting new relationship partners within their social context. Replicating existing findings, relational mobility was positively associated with pro-active tendencies that help people retain relationships-levels of intimacy and self-disclosure toward a close friend-indicating that friends tend to feel closer intimacy to their close friends, and reveal serious personal information to a larger degree in social contexts where opportunities to find and retain relationships with like-minded others are greater.
关系流动性是一个社会生态结构，用于量化一个社会给予个人多少自由和机会来选择和处理人际关系。过去的研究已经证实，关系流动性在各国之间存在差异，但没有大规模的研究考察关系流动性在一个国家内部可能存在的差异程度。我们报告了两项研究（研究 1，N=647；研究 2，N=7343），探讨了在巴西这个大陆大小的国家的 27 个州和五个地缘政治区域中，关系流动性在所有人群中的相似性或可变性。结果证实了关系流动性量表在所有巴西州的受访者中的测量等效性。值得注意的是，关系流动性得分在巴西各地区和各州之间是一致的，这表明巴西人在其社会背景中选择新的关系伙伴的机会存在共同的民族文化。关系流动性与积极主动的倾向呈正相关，这些倾向有助于人们维持关系，即亲密程度和自我披露水平对亲密朋友的关系——这表明在有更多机会找到并维持志同道合的人的关系的社会背景下，朋友往往会感到更亲密的亲密关系，并更愿意透露更严重的个人信息。
