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

描述（由申请人提供）： 虽然对ONDCP发起的药物预防运动的评估发现，运动对药物使用的影响的证据有限，但有理由提出，不同的分析可能会发现，运动确实有影响，但信息并没有以同样的方式影响所有人。大多数研究人员将非用户视为一个同质群体。通过纵向研究非使用者和非使用意图者之间的变化，将获得对变化过程的更深入的了解。检查非使用意图者和用户之间的类似模式也将有助于理解。以预防为重点，拟议的项目利用研究表明，吸毒是一种有目的的行为。青春期是身体、心理和环境变化的时期。作为这一过程的一部分，青少年开始将吸毒视为一种会阻碍或促进其适应不断变化的环境的行为。为了影响青少年不使用毒品，我们必须了解导致青少年将毒品使用与潜在的积极结果联系起来的环境和人际关系变化。特别令人感兴趣的是，毒品使用和意图的预测模型的划定，其中包括易于通过预防干预措施改变的变量。一个同样重要的目标是了解如何非用户，非使用意向者和用户不同的注意，并回应，禁毒信息。有一个长期的研究表明，个人将不同的关注和处理信息取决于信息被认为是多么相关。因此，青少年将根据他们认为相关的信息，以不同的方式关注和处理有关大麻的好处和危害的信息。整个拟议项目将为今后的干预工作提供新的路线图。相关性：拟议中的项目将提供新的见解的影响ONDCP赞助的药物预防运动，通过横截面和纵向分析的差异行为和反应模式的非用户，非使用意向者，和用户的大麻-一个部门几乎不存在，在目前的文献。知识也将通过考虑药物使用的潜在目的性和探索如何非用户，非使用意向者和大麻用户差异回忆和响应禁毒信息。

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.
