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.

项目摘要/摘要 越来越多的研究表明，兄弟姐妹对青少年的酒精和其他 使用物质。遗传知情设计的结果表明，这些兄弟姐妹之间的一致性 领域超出了共享遗传学和共享环境的影响，包括育儿，建议 这种兄弟姐妹的相似性是通过某种形式的社会影响而产生的。尽管有强烈的证据表明兄弟姐妹是独一无二的 毒品使用的社会化，对推动这些关联机制的研究欠发达。 迫切需要确定那些影响青少年关于实质决定的过程 使用。缺乏机械理解的理解无法理解基于家庭行为的发展 干预策略。因此，我们植根于生态和家庭系统框架，我们提出了一个综合性 兄弟姐妹的理论框架影响并确定微观和全球社会影响过程 说明同胞的相似性和差异。此外，从发展角度来看，我们将确定 老年和兄弟姐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。这项进步至关重要，因为以前的工作只有 被认为是自上而下的（即年龄较大的兄弟姐妹）社会化。测试生态原理，我们也将 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 青年的物质使用更普遍。样本将包括600个兄弟姐妹及其住宅父母 （〜2220名参与者）。使用基于地址的抽样策略，我们将招募包括焦点较老的家庭 兄弟姐妹在8 - 10年级（〜13-16岁）和多达三年级（〜12-15岁）的兄弟姐妹。 使用计划丢失的加速纵向纵向设计，将遵循参与者 在两年的过程中（即三个年度评估）。将采用两种数据收集方法 每个评估。首先，与父母的年度基于Internet的计算机协助自学浏览（CASI）和 青年将评估参与者的酒精和其他药物使用以及相关认知，心理社会 功能，同伴，父母和兄弟姐妹的关系素质。第二，一系列基于互联网的日记 访谈将由年轻和年长的兄弟姐妹完成。在连续四个周末，这些访谈 将评估兄弟姐妹的日常互动以及其活动的背景和伴侣的内容 （包括使用物质）。通常，将使用潜在变量建模（LVM）对目标进行测试。这个灵活 分析程序是有利的，因为它可以处理嵌套在内的日记和纵向数据 个人以及来自兄弟姐妹的数据进一步嵌套在家庭中。此外，LVM允许 有效测试介导和调节作用以及生长轨迹和相互影响。经过 确定同胞影响的特定机制，本研究将提供有关新的重要信息 基于家庭的干预措施的目标，以减少青少年物质使用。
