DESCRIPTION (provided by applicant): This proposal seeks to take advantage of a unique sample of siblings (participants in the Nonshared Environment in Adolescent Development project or NEAD) ideally suited to address critical issues on how sibling interaction provides an interpersonal context for the expression of deviant behavior in adolescence and adulthood. Although behavioral genetic studies have consistently shown that the shared environment has profound effects on the development of deviancy, there have been few attempts to isolate specific social processes underlying this association. Conversely, social process research has typically not evaluated family interaction from the perspective of genetic relatedness. By applying a comprehensive coding system to already collected videotaped sibling interactions in a genetically informative sample of adolescents, we propose to better characterize specific social reinforcement patterns in adolescence that serve to encourage deviant behavior, and also to determine how social influences may moderate the expression of genetic tendencies. Our specific focus is on sibling interaction, which appears to be a key shared environmental factor in adolescence. We will pursue these overall objectives through the execution of tour specific aims: (1) To utilize the genetically-informative design of the NEAD to determine the effect size of environmental and genetic contributions to social processes between siblings that are specific to reinforcement for deviancy in adolescence; (2) To employ multivariate biometrical models to determine if these specific social processes between siblings explain in part the latent social and genetic influences on deviancy typically inferred in behavioral genetic research; (3) To explore alternative models (both conceptual and computational) for associations between social influences on deviancy and genetic relatedness, including moderation models as well as tests for violations of the Equal Environments Assumption of the twin design; and (4) To test the specificity of the sibling effect model by extending prediction to other outcomes, particularly smoking, and depressive symptoms. The execution of these four specific aims will fill important gaps in our knowledge concerning social effects on deviancy, sibling influence on social development, and, perhaps most importantly, the interplay between genetic factors and interpersonal context in adolescent and adult social development. Such knowledge may be used to modify prevention and intervention programs that typically ignore the potent effects that siblings may have on the development and maintenance of deviant behavior in adolescence and into adulthood.

描述（由申请人提供）：该提案旨在利用独特的兄弟姐妹样本（青少年发展非共享环境项目或NEAD的参与者），非常适合解决有关兄弟姐妹互动如何为表达提供人际环境的关键问题。青少年和成年期的异常行为。尽管行为遗传学研究一直表明，共同的环境对越轨行为的发展有着深远的影响，但很少有人试图分离出这种关联背后的特定社会过程。相反，社会过程研究通常没有从遗传相关性的角度评估家庭互动。通过应用一个全面的编码系统，已经收集的录像兄弟姐妹的互动在一个遗传信息样本的青少年，我们建议更好地描述特定的社会强化模式，在青春期，有助于鼓励越轨行为，并确定如何社会影响可能会缓和遗传倾向的表达。 我们的具体重点是兄弟姐妹的互动，这似乎是一个关键的共享环境因素在青春期。我们将通过执行巡回赛的具体目标来实现这些总体目标：（1）利用NEAD的遗传信息设计来确定环境和遗传对兄弟姐妹之间社会过程的影响大小，这些影响是特定于青少年越轨行为的强化;（二）采用多变量生物统计学模型来确定兄弟姐妹之间的这些特定社会过程是否部分解释了对偏差的潜在社会和遗传影响行为遗传学研究中的典型推断;（3）探索替代模型（包括概念和计算）社会对偏差和遗传相关性的影响之间的关联，包括适度模型以及违反双胞胎设计的平等环境假设的测试;（4）通过扩展对其他结果的预测，特别是吸烟和抑郁症状，来检验同胞效应模型的特异性。这四个具体目标的执行将填补重要的空白，在我们的知识有关的社会影响偏差，兄弟姐妹的社会发展的影响，也许最重要的是，遗传因素和人际关系的背景下，在青少年和成人的社会发展之间的相互作用。这些知识可以用来修改预防和干预计划，通常忽略了兄弟姐妹可能对青少年和成年期偏差行为的发展和维持产生的潜在影响。
