Diversity in social relations is important for reducing prejudice. Yet, the question of when this occurs remains open. Using a social network approach, we test whether the link between outgroup attitudes and number of intra- and intergroup contacts is moderated by type of relationship (strong vs. weak ties) and personality (openness to experience) while also considering network structure (connections between contacts). In a culturally diverse sample of 122 immigrants residing in Barcelona, positive outgroup attitudes were predicted by several network characteristics: low proportion of intragroup contacts and high proportion of intergroup contacts among strong ties, high ethnic diversity among strong ties, low connectedness among contacts in the country of origin, and high connectedness between coethnic local and host national contacts. Openness to experience moderated these effects. These results affirm the intergroup benefits of having compositionally and structurally diverse networks, and the gain in examining intergroup dynamics at the meso level of analysis.

社会关系的多样性对于减少偏见很重要。然而，何时发生这种情况的问题仍然悬而未决。使用社交网络方法，我们测试了群体态度与群体内和群体间联系数量之间的联系是否通过关系的类型（强关系或弱联系）和性格（开放的经历）来调节，同时还考虑了网络结构（之间的联系）联系人）。在来自巴塞罗那的122个移民的文化差异样本中，通过以下几个网络特征预测了积极的外联态度：强势联系中的群体内部联系比例低，群体间联系比例高，强联系中种族差异高，联系中联系度低。原籍国，以及种族性的地方和东道国之间的高度联系。开放的经验减轻了这些影响。这些结果证实了拥有组成和结构上不同的网络所带来的群体间的好处，以及在细观分析水平上检查群体间动态的收益。
