Fraternity culture perpetuates traditional masculinity ideologies, but little research has considered the process by which men internalize these ideologies. Men may select into fraternities based on preexisting ideologies, or fraternities may have a socializing effect on ideologies. We used two longitudinal datasets to explore selection and socialization effects of fraternity membership on masculinity ideologies (gendered beliefs, gendered traits, and sexual double standard beliefs) and impersonal sex (sexual motives and multiple sex partners) among ethnically and racially diverse college men. Using dataset one (n = 166, M = 18.0 years old fall of first year), we explored the selection and socialization effects of fraternity membership on male role norms, masculine traits, and endorsement of the sexual double standard. Men who more strongly endorsed male role norms about status and the sexual double standard were more likely to join fraternities than other men, indicating selection effects. Using dataset two (n = 256, M = 18.5 years old fall of first year), we explored selection and socialization effects of fraternity membership on sex motives and multiple sex partners. We did not find much evidence for selection or socialization effects on sex motives and multiple sex partners. Our findings may inform intervention efforts for men before and during college.

博爱会员，传统男性气概和非个人性：选择和社会化影响。

博爱文化使传统的男子气概意识形态永存，但很少有研究考虑男人将这些意识形态内化的过程。男性可以根据既有的意识形态选择志趣相投的人，或者志趣相投的人可能会对意识形态产生社会影响。我们使用了两个纵向数据集来探讨兄弟会成员对男性和不同种族的大学男子气概中的男性气概意识形态（性别信念，性别特征和性双重标准信念）和非人格性行为（性动机和多个性伴侣）的选择和社会化影响。使用数据集一（n = 166，M =第一年秋天18.0岁），我们探讨了兄弟会会员对男性角色规范，男性特征和性双重标准认可的选择和社会化影响。较男性更认同男性关于身份和性双重标准的角色规范的男性比其他男性更有可能加入兄弟情谊，这表明了选择效应。使用第二个数据集（n = 256，M =第一年秋天18.5岁），我们探讨了兄弟会成员对性动机和多个性伴侣的选择和社会化影响。我们没有发现足够的证据证明选择或社交对性动机和多性伴侣的影响。我们的发现可能会为上大学之前和期间的男性干预工作提供信息。我们探讨了兄弟会成员对性动机和多个性伴侣的选择和社会化影响。我们没有发现足够的证据证明选择或社交对性动机和多性伴侣的影响。我们的发现可能会为上大学之前和期间的男性干预工作提供信息。我们探讨了兄弟会成员对性动机和多个性伴侣的选择和社会化影响。我们没有发现足够的证据证明选择或社交对性动机和多性伴侣的影响。我们的发现可能会为上大学之前和期间的男性干预工作提供信息。
