The purpose of this study was to examine the impact of an older brother's drug use on his younger brother's drug use viewed in the context of parent and peer influences. The sample consisted of 278 White, middle-class male college students and their oldest brothers, who were given questionnaires assessing drug behavior. Results indicated that older brother, parental, and peer drug use each had an independent impact on younger brother's use. The degree of influence varied, with drug modeling by peers and older brothers having a stronger association with younger brother drug use than did parental drug modeling. Further, the older brother's advocacy of drugs was associated with his younger brother's use even if the older brother did not serve as a drug model. Similarly, older brother drug modeling was of importance even if he did not advocate use. Finally, interactive results suggested that older brothers who did not use drugs could offset the negative effects of parental drug risks on younger brother use. Also, younger brothers were least likely to use drugs if both older brothers and peers served as models for nonuse.
本研究的目的是考察哥哥的吸毒行为在父母及同伴影响的背景下对弟弟吸毒行为的影响。样本包括278名白人、中产阶级男性大学生及其哥哥，他们被给予评估吸毒行为的问卷。结果表明，哥哥、父母及同伴的吸毒行为各自对弟弟的吸毒行为都有独立影响。影响程度各不相同，同伴和哥哥的吸毒示范与弟弟吸毒行为的关联比父母的吸毒示范更强。此外，即使哥哥没有充当吸毒榜样，其对毒品的宣扬也与弟弟的吸毒行为有关。同样，即使哥哥不宣扬吸毒，其吸毒示范也很重要。最后，交互作用结果表明，不吸毒的哥哥可以抵消父母吸毒风险对弟弟吸毒行为的负面影响。此外，如果哥哥和同伴都充当不吸毒的榜样，弟弟吸毒的可能性最小。
