Guided by the Social Identity Model of Collective Action, the current research utilizes a three-wave longitudinal study collected pre and post the 2020 U.S. Presidential election to examine the motivations underlying Latino Americans’ group-based social media engagement (N = 1,050). Results revealed that Time 1 group (Latino) identity increased Time 2 perceptions of social media as efficacious in improving group outcomes, which in turn increased Time 3 group-based social media engagement. Although T1 Latino identification was not significantly associated with T2 perceptions of personal or group-based injustice, the former (but not the latter) increased T3 group-based social media engagement. Our findings reflect that marginalized group members engage with social media in part because they believe it is efficacious in improving their disadvantageous group status. This may be an especially attractive strategy for those who face individual experiences of unjust treatment.

拉美裔美国人基于群体的社交媒体参与的动机

在集体行动的社会认同模型的指导下，当前的研究利用在 2020 年美国总统大选前后收集的三波纵向研究来检验拉美裔美国人基于群体的社交媒体参与的动机 (N = 1,050)。结果显示，时间 1 群体（拉丁裔）身份增加了时间 2 对社交媒体的看法，认为社交媒体可有效改善群体结果，这反过来又增加了时间 3 基于群体的社交媒体参与度。尽管 T1 拉丁裔认同与 T2 对个人或群体不公正的看法没有显着关联，但前者（但不是后者）增加了 T3 群体社交媒体参与度。我们的研究结果反映出边缘化群体成员使用社交媒体的部分原因是他们认为社交媒体可以有效改善他们的弱势群体地位。对于那些面临不公正待遇的个人经历的人来说，这可能是一个特别有吸引力的策略。
