Sibling substance use is a known correlate of adolescent substance use. Yet, not all siblings are equally influential. Sibling influence has been found to vary by age gap, sex, and birth order. Little research, however, has investigated whether siblings' peer context is also a source of variation. The present study tested whether more popular siblings were more influential for adolescent use of cigarettes, alcohol, and marijuana. Data were obtained from sibling pairs in the National Longitudinal Study of Adolescent Health. Findings indicate that older siblings have more influence on younger sibling marijuana use when they have more friends. These findings contribute to prior work examining which siblings are more influential and highlight the need to consider siblings as part of a greater peer context.
兄弟姐妹的物质使用情况是青少年物质使用的一个已知相关因素。然而，并非所有兄弟姐妹都具有同等影响力。研究发现，兄弟姐妹的影响力会因年龄差距、性别和出生顺序而有所不同。然而，很少有研究调查兄弟姐妹的同伴背景是否也是一个影响因素。本研究测试了更受欢迎的兄弟姐妹对青少年吸烟、饮酒和使用大麻的影响是否更大。数据来自青少年健康全国纵向研究中的兄弟姐妹对。研究结果表明，年龄较大的兄弟姐妹在有更多朋友时，对年龄较小的兄弟姐妹使用大麻的影响更大。这些发现为之前关于哪些兄弟姐妹更具影响力的研究做出了贡献，并强调了将兄弟姐妹视为更大同伴背景一部分的必要性。
