对543名中学生进行的一项新研究发现,最好的朋友主要影响情感福祉、学术表现和个人行为,而受欢迎的同龄人则影响公共行动,如社交媒体的使用和身体形象问题。 A new study of 543 middle school students finds best friends primarily influence emotional well-being, academic performance, and personal behaviors, while popular peers shape public actions like social media use and body image concerns. 该研究由佛罗里达大西洋大学和Mykolas Romeris大学牵头,是第一个直接比较这两种同龄人影响的研究,显示青少年利用亲密朋友来提供情感支持和受欢迎同学来提供社交提示。 The research, led by Florida Atlantic University and Mykolas Romeris University, is the first to directly compare both types of peer influence, showing teens use close friends for emotional support and popular classmates for social cues. 调查结果表明,干预措施应该针对具体的同龄人动态——加强心理健康的友谊,并促使受欢迎的学生改变围绕外貌和在线行为的不健康规范。 Findings suggest interventions should target specific peer dynamics—strengthening friendships for mental health and engaging popular students to shift unhealthy norms around appearance and online behavior.
