This study examined whether social contagion of anxiety symptoms is present between siblings during early adolescence and whether this process is moderated by sex, relationship quality, and zygosity. Based on 634 monozygotic and dizygotic twins (336 females) assessed in Grades 6 and 7, anxiety symptoms and sibling relationship quality were measured with self-report questionnaires. The predictive association of the co-twin's level of anxiety with adolescents' own increased anxiety 1 year later was only observed in same-sex twin dyads (monozygotic and dizygotic) and was higher for those who perceived a higher level of relationship quality with their co-twin. Raising awareness of a possible sibling contagion of anxiety may be useful for preventing the development of anxiety symptoms in youth.
本研究考察了青少年早期兄弟姐妹之间是否存在焦虑症状的社交传染，以及这种过程是否受到性别、关系质量和同卵双生子的影响。基于 634 对同卵和异卵双胞胎（336 名女性）在六年级和七年级的评估，焦虑症状和兄弟姐妹关系质量通过自我报告问卷进行测量。只有在同性别双胞胎（同卵和异卵）中，双胞胎中一方的焦虑水平与青少年自身一年后焦虑水平升高之间才存在预测关联，而且对于那些与同胞关系质量感知更高的人来说，这种关联更为明显。提高对可能的兄弟姐妹焦虑传染的认识，可能有助于预防青少年焦虑症状的发展。
