Marijuana use patterns: Temporal change in predictors, perceptions, and ad impact

描述(由申请人提供)： 尽管对ONDCP赞助的毒品预防运动的评价发现了运动对毒品使用产生影响的有限证据，但有理由提出，不同的分析可能会发现运动确实产生了影响--但这些信息并不以同样的方式影响所有人。大多数研究人员将非使用者视为同质群体。通过纵向研究非使用者和不使用意向者之间的变化，将获得对变化过程的更多洞察。考察不使用意向者和使用者之间的相似模式也将有助于理解。以预防为重点，拟议的项目利用了表明吸毒是一种有目的的行为的研究。青春期是一个生理、心理和环境都发生变化的时期。作为这一过程的一部分，青少年逐渐将吸毒视为一种行为，它将阻碍或促进他们适应不断变化的环境。为了影响青少年不吸毒，我们必须了解环境和人际关系的变化，这些变化导致青少年将吸毒与潜在的积极结果联系在一起。特别令人感兴趣的是描述药物使用和意图的预测模型，其中纳入了可通过预防性干预而改变的变量。一个同样重要的目标是了解非使用者、非使用者意向者和使用者如何不同地注意到和回应禁毒信息。有一项由来已久的研究表明，根据信息被感知的相关性，个人会以不同的方式处理和处理信息。因此，青少年将根据他们认为相关的信息，以不同的方式处理和处理关于大麻的益处和危害的信息。这一拟议项目的总体情况将为今后的干预工作提供新的路线图。相关性：拟议的项目将通过对不使用大麻的人、不使用大麻的人和使用大麻的人的不同行为和反应模式的横断面和纵向分析，对ONDCP赞助的毒品预防运动的影响提供新的见解--这一分类在目前的文献中几乎不存在。还将通过考虑毒品使用的潜在目的性质以及探索不使用大麻的人、不使用大麻的人和吸食大麻的人如何不同地回忆和回应禁毒信息来获得知识。

DESCRIPTION (provided by applicant): Although evaluations of the ONDCP-sponsored drug prevention campaign have found limited evidence of campaign impact on drug use, it is reasonable to propose that different analyses may find that the campaign did have an impact-but that the messages did not impact all individuals in the same way. Most researchers treat non-users as a homogeneous group. By longitudinally studying change between non-users and non-using intenders, greater insight into the change process will be attained. Inspecting similar patterns between non-using intenders and users also will facilitate understanding. Taking a preventive focus, the proposed project draws on research indicating that drug use is a purposeful behavior. Adolescence is a time of physical, psychosocial, and environmental change. As part of this process adolescents come to see drug use as an act that will hinder or facilitate adjustment to their changing environment. To influence adolescents not to use drugs, we must understand the environmental and interpersonal changes that lead adolescents to associate drug use with potentially positive outcomes. Of particular interest is the delineation of predictive models of drug use and intent that incorporate variables amenable to change via preventive interventions. An equally important goal is to understand how non-users, non-using intenders, and users differentially notice, and respond to, anti-drug messages. There is a long-standing body of research demonstrating that individuals will differentially attend to and process information depending on how relevant that information is perceived to be. It follows that adolescents will attend to and process information about the benefits and harms of marijuana differently depending what information they see as relevant. The totality of this proposed project will provide a new roadmap for future intervention efforts. Relevance: The proposed project will provide new insight into the impact of the ONDCP-sponsored drug prevention campaign, via cross-sectional and longitudinal analyses on the differential behavior and response patterns of non-users, non-using intenders, and users of marijuana-a division virtually non-existent in the current literature. Knowledge will also be gained by considering the potentially purposive nature of drug use and exploring how non-users, non-using intenders, and users of marijuana differentially recall and respond to anti-drug information.
