This study examined the sibling relationship "having an older brother" and its effect on the younger sibling's stage of drug use. Sibling effects were examined in the context of the younger sibling's peer group. Data collected on 339 9th and 10th grade students indicated that domains of older sibling and peer factors each had independent lines of relationship to the younger sibling's drug use. The older brother's impact on his younger sibling's drug use varied, depending on friends' drug use, sex of the younger sibling, and whether or not the younger sibling identified with the older brother.
本研究考察了“有哥哥”这种兄弟姐妹关系及其对弟弟妹妹吸毒阶段的影响。在弟弟妹妹的同龄人群体背景下考察了兄弟姐妹的影响。对339名九年级和十年级学生收集的数据表明，哥哥因素和同伴因素各自与弟弟妹妹的吸毒情况有独立的关系线。哥哥对弟弟妹妹吸毒的影响各不相同，这取决于朋友的吸毒情况、弟弟妹妹的性别，以及弟弟妹妹是否认同哥哥。
