PROJECT SUMMARY/ABSTRACT A growing body of research indicates that siblings have marked influence on adolescents' alcohol and other substance use. Results from genetically informed designs reveal that concordance between siblings in these domains exceeds the influence of shared genetics and shared environments, including parenting, suggesting that sibling similarities arise via some form of social influence. Despite strong evidence that siblings are unique socializers of substance use, research on the mechanisms driving these associations is underdeveloped. There is a critical need to identify those processes that influence adolescents' decisions regarding substance use. The lack of mechanistic understanding precludes informed development of family-based behavioral intervention strategies. Thus, rooted in ecological and family systems frameworks, we propose an integrative theoretical framework of sibling influence and identify the micro- and global-social influence processes that account for sibling similarities and differences. Additionally, taking a developmental perspective, we will identify the dual trajectories and reciprocal associations between older and younger siblings' substance use behaviors and related cognitions from early through late adolescence. This advance is critical, as previous work has only considered top-down (i.e., older to younger sibling) socialization. Testing ecological principles, we will also investigate the degree to which community characteristics moderate the influence of sibling socialization and youth's substance use more generally. The sample will include 600 sibling pairs and their residential parents (~2220 participants). Using address based sampling strategies, we will recruit families that include a focal older sibling in grades 8-10 (~13-16 years of age) and a sibling up to three grades younger (~12-15 years of age). Using an accelerated longitudinal within-family design with planned missingness, participants will be followed over the course of two years (i.e., three annual assessments). Two data collection methods will be employed at each assessment. First, annual internet-based computer assisted self-interviews (CASI) with parents and youth will assess participants' alcohol and other substance use and related cognitions, psychosocial functioning, and peer, parent and sibling relationship qualities. Second, a series of internet-based diary interviews will be completed by younger and older siblings. Over four consecutive weekends, these interviews will assess the content of siblings' daily interactions as well as the contexts and companions of their activities (including substance use). In general, the aims will be tested using latent variable modeling (LVM). This flexible analytic procedure is advantageous as it can handle both diary and longitudinal data which are nested within individuals as well as data from siblings which are further nested within families. Furthermore, LVM permits the efficient testing of mediating and moderating effects as well as growth trajectories and reciprocal effects. By identifying specific mechanisms of sibling influence, this study will provide important information about new targets for family-based interventions to reduce adolescent substance use.

项目概要/摘要 越来越多的研究表明，兄弟姐妹对青少年的饮酒和其他行为有显着影响。 物质的使用。遗传信息设计的结果表明，这些兄弟姐妹之间的一致性 领域超出了共同遗传和共同环境的影响，包括养育子女，这表明 兄弟姐妹的相似之处是通过某种形式的社会影响而产生的。尽管有强有力的证据表明兄弟姐妹是独一无二的 物质使用的社交者，对驱动这些关联的机制的研究尚不充分。 迫切需要确定影响青少年物质决定的过程 使用。缺乏机制性的理解阻碍了基于家庭的行为的明智发展 干预策略。因此，植根于生态和家庭系统框架，我们提出了一个综合的 兄弟姐妹影响的理论框架，并确定微观和全球社会影响过程 考虑兄弟姐妹的相似点和差异。此外，从发展的角度来看，我们将确定 哥哥姐姐和弟弟妹妹的物质使用行为之间的双重轨迹和相互关联 以及从青春期早期到晚期的相关认知。这一进展至关重要，因为之前的工作只 被认为是自上而下（即从年长到年幼的兄弟姐妹）的社会化。检验生态原则，我们也会 调查社区特征在多大程度上调节兄弟姐妹社会化的影响和 青少年的物质使用更为普遍。样本将包括 600 对兄弟姐妹及其寄宿父母 （约 2220 名参与者）。使用基于地址的抽样策略，我们将招募包括重点老年人在内的家庭 8-10 年级（约 13-16 岁）的兄弟姐妹和比他小三年级的兄弟姐妹（约 12-15 岁）。 使用加速纵向家庭内设计和有计划的缺失，将跟踪参与者 为期两年（即三次年度评估）。将采用两种数据收集方法 每次评估。首先，每年与家长和家长进行基于互联网的计算机辅助自我访谈（CASI） 青少年将评估参与者的酒精和其他药物使用情况以及相关认知、社会心理 功能以及同伴、父母和兄弟姐妹的关系质量。二、网络日记系列 访谈将由年幼的兄弟姐妹和年长的兄弟姐妹完成。连续四个周末，这些采访 将评估兄弟姐妹日常互动的内容以及他们活动的背景和同伴 （包括物质使用）。一般来说，目标将使用潜变量建模（LVM）进行测试。这种灵活的 分析过程是有利的，因为它可以处理嵌套在其中的日记数据和纵向数据 个人以及来自进一步嵌套在家庭中的兄弟姐妹的数据。此外，LVM 允许 有效测试中介和调节效应以及增长轨迹和交互效应。经过 确定兄弟姐妹影响的具体机制，这项研究将提供有关新的重要信息 以家庭为基础的干预措施减少青少年药物使用的目标。
