Personality affects dyadic relations and teamwork, yet its role among groups of friends has been little explored. We examine for the first time whether similarity in personality enhances the effectiveness of real-life friendship groups. Using data from a longitudinal study of a European fraternity (10 male and 15 female groups), we investigate how individual Big Five personality traits were associated with group formation and whether personality homophily related to how successful the groups were over 1 year ( = 147-196). Group success was measured as group performance/identification (adoption of group markers) and as group bonding (using the inclusion-of-other-in-self scale). Results show that individuals' similarity in neuroticism and conscientiousness predicted group formation. Furthermore, personality similarity was associated with group success, even after controlling for individual's own personality. Especially higher group-level similarity in conscientiousness was associated with group performance, and with bonding in male groups.
人格会影响二元关系和团队合作，但其在朋友圈子中的作用却鲜有研究。我们首次考察人格相似性是否能提高现实生活中朋友圈子的效能。利用一项针对欧洲兄弟会的纵向研究数据（10个男性团体和15个女性团体），我们调查了个体的大五人格特质如何与团体形成相关联，以及人格同质性是否与团体在1年时间里的成功程度有关（= 147 - 196）。团体成功的衡量指标包括团体表现/认同（采用团体标志）以及团体凝聚力（使用自我包含他人量表）。结果表明，个体在神经质和尽责性方面的相似性预测了团体的形成。此外，即使在控制了个体自身的人格之后，人格相似性仍与团体成功相关。尤其是团体层面更高的尽责性相似性与团体表现以及男性团体的凝聚力相关。
