The present study aimed to integrate the social identity approach to health and well‐being with social network analysis. Previous research on the effects of social network centrality on stress has yielded mixed results. Building on the social identity approach, we argued that these mixed results can be explained, in part, by taking into account the degree to which individuals identify with the social network. We hence hypothesized that the effects of social network centrality on stress are moderated by social identification. Using a full roster method, we assessed the social network of first‐year psychology students right after the start of their study programme and three months later. The effects of network centrality (betweenness, closeness, eigenvector centrality) and social identification on stress were examined using structural equation models. As predicted, our results revealed a significant interaction between network centrality and social identification on stress: For weakly or moderately identified students, network centrality was positively related to stress. By contrast, for strongly identified students, network centrality was unrelated to stress. In conclusion, our results point to the perils of being well‐connected yet not feeling like one belongs to a group.

社会网络中心性和社会认同对压力的交互作用

本研究旨在将社会身份识别方法用于健康和福祉与社会网络分析相结合。先前关于社交网络中心性对压力的影响的研究得出了不同的结果。在社会认同方法的基础上，我们认为，可以部分考虑个人对社会网络的认同程度来解释这些混杂的结果。因此，我们假设社交网络中心性对压力的影响可以通过社交认同来缓和。在开始学习计划后以及三个月后，我们使用完整的花名册方法评估了一年级心理学学生的社交网络。网络中心性的影响（中间性，紧密性，使用结构方程模型检查了特征向量中心性和对压力的社会认同。如预期的那样，我们的结果显示了网络中心性和压力下的社会认同之间的显着相互作用：对于弱或中等识别的学生，网络中心性与压力成正相关。相比之下，对于高度认同的学生，网络中心性与压力无关。总而言之，我们的研究结果表明，人际关系良好但感觉不到自己属于一个群体的危险。
