ABSTRACT The overarching objective of the proposed research is to evaluate cannabis identity, or the extent to which one views cannabis use as part of their self-concept, as a cognitive and developmental risk factor for adolescent cannabis misuse. Adolescent cannabis misuse is associated with numerous negative consequences and is a growing public health concern given rapidly changing policies surrounding cannabis use in the US. Adolescent cannabis use and misuse may increase in states that legalize recreational cannabis use with initial evidence of this occurring in states (Washington) that have already legalized use. Despite these trends, the cognitive and developmental mechanisms thought to underlie cannabis misuse are poorly understood relative to other substances. Recent theoretical models assert that substance identity, or the extent to which one views substance use as part of their self-concept, is a unique and important cognitive risk factor for substance misuse. Substance-related identities can be measured with explicit (e.g., self-report) and implicit (e.g., reaction time) measures; and both uniquely predict misuse, dependence, and treatment outcomes among alcohol and tobacco users. To date, there are no well-validated measures of cannabis identity, which could represent novel tools for adolescent cannabis misuse screening and potential targets for prevention and intervention strategies. The proposed research aims to address this gap and implements a mixed-methods approach across two phases: Phase 1) 48 adolescents (15-18 years old) in Washington will attend focus groups to discuss the phenomenological experience of having and/or developing a cannabis user or non-user identity. Themes from focus groups will inform stimuli development for two novel Cannabis Identity Implicit Associations Tests (CI-IATs), a type of measure used to assess implicit identification with substance use. 10 additional adolescents will then complete structured interviews to pilot-test the CI-IATs and to rate and discuss CI-IAT stimuli comprehension. Phase 2) 150 adolescents will complete three online assessment batteries, each separated by three months, that include the two CI-IATs, an explicit measure of cannabis identity, and measures of cannabis use, misuse, and cannabis use social norms. To test a dual process model of cannabis identity, the incremental predictive validity of implicit and explicit measures of cannabis identity will be examined in models predicting current and prospective cannabis use and misuse. The incremental predictive validity of cannabis identity measures will also be examined relative to a well-established cognitive risk factor for cannabis misuse (social norms). The research findings will advance theory, potentially improve the prediction of adolescent cannabis misuse, and potentially identify a unique cognitive and developmental risk factor for cannabis misuse that may be targeted among future prevention and intervention efforts.

抽象的 拟议研究的总体目标是评估大麻的身份，或者一种大麻的程度 将大麻的使用视为自我概念的一部分，视为青少年的认知和发育风险因素 大麻滥用。青少年滥用大麻会带来许多负面后果，是一个严重的问题 鉴于美国有关大麻使用的政策迅速变化，公共卫生问题日益受到关注。青少年 在娱乐性大麻使用合法化的国家，大麻的使用和滥用可能会增加，并有初步证据表明 这种情况发生在已经合法化使用的州（华盛顿）。尽管有这些趋势，认知和 相对于其他机制，人们对大麻滥用背后的发育机制知之甚少。 物质。最近的理论模型断言，物质同一性，或者人们认为的程度 物质使用作为自我概念的一部分，是物质使用的一个独特且重要的认知风险因素 滥用。与物质相关的身份可以通过显式（例如，自我报告）和隐式（例如， 反应时间）措施；两者都独特地预测了滥用、依赖和治疗结果 酗酒和吸烟者。迄今为止，还没有经过充分验证的大麻身份测量方法，这可能 代表青少年大麻滥用筛查的新工具以及预防和预防的潜在目标 干预策略。拟议的研究旨在解决这一差距并实施混合方法 方法分两个阶段进行： 第一阶段）华盛顿州的 48 名青少年（15-18 岁）将参加焦点课程 小组讨论拥有和/或发展大麻使用者或非使用者的现象学经验 身份。焦点小组的主题将为两部小说《大麻隐含身份》的刺激发展提供信息 关联测试 (CI-IAT)，一种用于评估对物质使用的内隐认同的测量方法。 10 然后，其他青少年将完成结构化访谈，以试点测试 CI-IAT 并进行评分和讨论 CI-IAT 刺激理解。第 2 阶段）150 名青少年将完成三套在线评估， 每个间隔三个月，其中包括两个 CI-IAT（大麻身份的明确衡量标准），以及 大麻使用、滥用和大麻使用社会规范的措施。测试大麻的双过程模型 身份，大麻身份的隐式和显式测量的增量预测有效性将是 在预测当前和未来大麻使用和滥用的模型中进行了检查。增量预测 大麻身份测量的有效性也将根据既定的认知风险进行审查 大麻滥用的因素（社会规范）。研究结果将推进理论发展，有可能改善 预测青少年大麻滥用，并可能确定独特的认知和发育风险 未来预防和干预工作可能针对的大麻滥用因素。
