Drawing data from the first year of a longitudinal study of 508 families with focal adolescents aged 11 to 13 years and their older siblings (14 to 18 years), the investigators examined the influence of older siblings' drug-using attitudes and behaviors, in comparison with parental and peer drug-using attitudes and behaviors, on focal adolescents' nonuse and use of substances. Older siblings are frequently a source of drugs and use substances with their young siblings, though peers remain the primary source and the most frequent coursers. For most substances, frequency of use was predicted by older sibling and peer substance use, each after controlling for the other. Parental drug use was found to be minimal in comparison to older siblings and peers. Findings relative to the potentially important role of older siblings in influencing their younger siblings' drug-using behavior are discussed.
研究人员从一项针对508个家庭的纵向研究的第一年收集数据，这些家庭中有11至13岁的重点青少年及其年长的兄弟姐妹（14至18岁），他们比较了年长兄弟姐妹的吸毒态度和行为与父母及同伴的吸毒态度和行为对重点青少年物质未使用和使用情况的影响。年长的兄弟姐妹经常是毒品的来源，并与他们年幼的兄弟姐妹一起使用毒品，尽管同伴仍然是主要来源和最频繁的使用者。对于大多数物质，在相互控制之后，年长兄弟姐妹和同伴的物质使用情况可预测使用频率。与年长兄弟姐妹和同伴相比，父母的吸毒情况被发现极少。讨论了有关年长兄弟姐妹在影响其年幼兄弟姐妹吸毒行为方面潜在重要作用的研究结果。
