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R01，竞争连续研究将研究华盛顿州成年大麻（21岁以上）的最新合法化与大麻使用模式与使用相关风险行为的模式，包括其他药物使用，行为问题，艾滋病毒性问题与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提的变化之间的联系，包括青年规范；家长大麻和其他物质使用和规范；育儿实践；感知到同伴，兄弟姐妹以及伴侣的使用和规范；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可以通过使用青年大麻的前提变化来解释（介导）。拟议的项目非常适合解决这些目标。它建立在代际项目（TIP）的基础上，该研究使用加速的纵向设计，旨在了解父母药物使用对儿童发育的影响（n = 383个家庭，80％的家庭居住在华盛顿州）。提示包括从以前的纵向小组研究（西雅图社会发展项目（SSDP））中汲取的父母，最古老的亲生孩子和第二个护理人员。提示收集了最近（2010年）的临时数据，为评估这一重要政策转变奠定了基础。可用的预选青年数据跨越1-22岁，父母数据跨度为27-35（2002-2010，7评估）。拟议的研究将在2015年，2016年和2017年与父母，青年和第二个护理人员一起在2015年，2016年和2017年增加3个年度数据收集。拟议的项目是由社会发展模型和问题行为理论驱动的。对成人大麻合法大麻的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与青少年大麻，相关的风险行为及其先例之间的联系。加速的纵向设计将使我们能够使用重叠的队列来绘制青年成果前后的轨迹，并在联合结合后，解散发展和历史（政策变化），并促进对大麻合法化和发展的交汇处的理解，这些方式以其他研究不能。我们知道，在华盛顿或科罗拉多州，对青年的纵向研究没有其他持续的加速研究，这使得提示以一种发展知情的方式独特地旨在检查大麻合法化对青年的影响。结果将提供至关重要的信息，以告知州和国家大麻政策，并在合法化的背景下预防青年大麻使用。
