SIBLING MUTUAL INTERACTION, DRUG USE, AND DEVIANCE

犯罪行为和药物滥用是常见和持续存在的问题 在美国青年中。 越轨行为是“家族性的”：当一个家庭成员 表现出异常，对其他家庭成员的风险要比 对一般人的风险。 以前大多数关于越轨行为的研究 确定了父母的榜样和养育子女的做法， 可能是家族相似的原因 在这一分析中被忽略的是 家庭内主要环境影响是兄弟姐妹的可能性 相互作用。 拟议中的项目是一项关于药物使用和异常行为的兄弟研究 （轻微至严重的违法行为）。 样本人群包括 第一轮11-14岁的兄弟姐妹，他们将接受匿名调查， 调查问卷，每隔一年进行三次。 问卷包含衡量四个拟议过程的尺度， 兄弟姐妹之间的相互影响：强迫、认同、模仿和直接 影响力的社会 每个过程对行为相似性的影响 将确定兄弟姐妹;如果影响过程影响行为 相似性，我们可以推断它是有效的（这是不同的 （接受兄弟姐妹的口头证词）。 两种互补形式 将使用统计分析：多元回归模型， 纵向数据的横截面数据结构方程模型。 在 总之，拟议的项目将1）证明兄弟姐妹的存在 相互作用效应，2）评估这些效应的理论模型，以及 (3)对异常行为和药物滥用的遗传性进行限制。

Delinquent behavior and drug abuse are common and persistent problems among American youth. Deviance is "familial": when one family member exhibits deviance, the risk to other family members is much greater than the risk to people in general. Most previous research on deviance has identified parental role models and child rearing practices as the probable cause of familial resemblance. Neglected in this analysis is the possibility that the major environmental effect within families is sibling mutual interaction. The proposed project is a sibling study of drug use and deviant behavior (minor to serious delinquent acts). The sample population consists of siblings aged 11-14 years at Round 1, who will be surveyed by anonymous questionnaire on three occasions at one year intervals. The questionnaire contains scales to measure four proposed processes of sibling mutual influence: coercion, identification, modeling, and direct influence. The effect of each process on the behavioral similarity of siblings will be determined; if the influence process affects behavioral similarity, we can infer that it is operative (which is different from accepting the verbal testimony of the siblings). Two complementary forms of statistical analysis will be used: a multiple regression model of cross-sectional data structural equation model of longitudinal data. In sum, the proposed project will 1) demonstrate the existence of sibling interaction effects, 2) evaluate theoretical models of those effects, and (3) place boundaries on the heritabilities of deviance and drug abuse.
