DESCRIPTION (provided by applicant): This 5-year R01, competing continuation study will examine links between the recent legalization of cannabis for adults (age 21+) in Washington State and patterns of cannabis use and related risk behaviors, including other substance use, conduct problems, and HIV sexual risk behavior (SRB) among youth. It also will examine links between cannabis legalization for adults and changes in antecedents of youth cannabis use, including youth norms; parent cannabis and other substance use and norms; parenting practices; perceived peer, sibling, and partner use and norms; and availability. Analyses will test whether any changes in youth cannabis use and associated risk behavior are explained (mediated) by changes in antecedents of youth cannabis use. The proposed project is uniquely suited to address these goals. It builds on The Intergenerational Project (TIP), a study that uses an accelerated longitudinal design, and aims to understand the effects of parent substance use on child development (n = 383 families, 80% living in Washington State). TIP includes parents drawn from a prior longitudinal panel study (the Seattle Social Development Project (SSDP)), their oldest biological child, and a second caregiver when available. TIP collected recent (2010) pre-legalization data, setting the stage for an evaluation of this important policy shift. Availabl pre-legalization youth data span ages 1-22 and parent data span ages 27-35 (2002-2010, 7 assessments). The proposed study would add 3 additional annual data collections post-legalization in 2015, 2016, and 2017 with parents, youth, and second caregivers. The proposed project is driven by the Social Development Model and Problem Behavior Theory. The effects on youth of legalized adult cannabis use are unknown. This study will be the first to test links between cannabis legalization for adults and youth cannabis use, associated risk behavior, and their antecedents. The accelerated longitudinal design will enable us to use overlapping cohorts to map trajectories of youth outcomes pre- and post-legalization, disentangling development and history (policy change) and facilitating understanding about the intersection of cannabis legalization and development in ways that other studies cannot. We are aware of no other ongoing accelerated longitudinal study of youth in either Washington or Colorado, making TIP uniquely poised to examine the impact of cannabis legalization on youth in a developmentally informed way. Results will provide information critical to inform state and national cannabis policy and prevention of youth cannabis use in the context of legalization.

描述（由申请人提供）：这项为期5年的R 01竞争性继续研究将检查最近华盛顿州成年人（21岁以上）大麻合法化与大麻使用模式和相关风险行为之间的联系，包括其他物质使用，行为问题和青年中的艾滋病毒性风险行为（SRB）。它还将研究成人大麻合法化与青少年大麻使用前因变化之间的联系，包括青少年规范;父母大麻和其他物质的使用和规范;育儿实践;感知的同龄人，兄弟姐妹和伴侣使用和规范;和可用性。分析将测试 青少年大麻使用和相关风险行为的任何变化是否由青少年大麻使用前因的变化解释（介导）。拟议的项目特别适合实现这些目标。它建立在代际项目（TIP）的基础上，该研究采用加速纵向设计，旨在了解母体物质使用对儿童发育的影响（n = 383个家庭，80%居住在华盛顿州）。TIP包括从先前的纵向小组研究（西雅图社会发展项目（SSDP））中抽取的父母，他们最大的亲生子女，以及第二个照顾者（如果可用）。TIP收集了最近（2010年）合法化前的数据，为评估这一重要政策转变奠定了基础。合法化前的青年数据涵盖1-22岁，父母数据涵盖27-35岁（2002-2010年，7次评估）。拟议的研究将在2015年、2016年和2017年增加3个额外的合法化后年度数据收集，包括父母、青少年和第二照顾者。本研究以社会发展模式与问题行为理论为基础。成年人合法使用大麻对青年的影响尚不清楚。这项研究将是第一个测试成人大麻合法化和青年大麻使用，相关风险行为及其前因之间的联系。加速纵向设计将使我们能够使用重叠的队列来绘制合法化前后青年成果的轨迹，解开发展和历史（政策变化），并以其他研究无法理解的方式促进对大麻合法化和发展交叉点的理解。我们知道，在华盛顿或科罗拉多，没有其他正在进行的青年加速纵向研究，使TIP独特地准备以发展知情的方式研究大麻合法化对青年的影响。结果将提供重要信息，为州和国家大麻政策提供信息，并在合法化的背景下预防青少年使用大麻。
