DESCRIPTION (provided by applicant): Understanding why young adolescents begin to drink and go on to escalate alcohol use is a key element to preventing adolescent alcohol misuse. Although it is known that adolescents initiate drinking in response to social influences, the entertainment industry remains an understudied influence, and we know of no research examining the role of movies as an influence on adolescent drinking. Our preliminary data indicates that viewing movie alcohol use influences initiation of drinking. Movie depictions of sexual behavior and violence concurrent with alcohol use may have additional effects, and continued exposure to movie depictions could influence escalation of alcohol use and possibly other outcomes (e.g., aggressive behavior). However, the nature of these media effects has not been extensively investigated in large representative samples. To learn more about the effect of movies on youth alcohol use and violence, we propose to conduct theoretically-based analyses on two (2) data sets, both with youth aged 10-14 at baseline: Study 1 is a 2-wave data set from a school sample covering 2415 Northern New England students, and Study 2 is a 4-wave data set from a nationally representative sample of 6522 U.S. adolescents 10-14 years. We aim to a) examine content analysis data on alcohol use, alcohol brand depictions, violence, sex, and illicit drug use in over 1000 popular contemporary movies released between 1990 and 2005; b) obtain estimates of adolescents' exposure to these factors in movies and examine the relation between such movie exposures and adolescents' alcohol use and other problem behaviors; c) test for moderation of movie exposure effects by selected variables (e.g., gender, ethnicity, self-control); d) test for indirect effects of movie exposure on adolescents' alcohol use through mediators such as alcohol expectancies and cognitive images of users; e) in longitudinal analyses using latent growth modeling, examine changes in adolescents' attitudes and behavior over time as a function of ongoing exposure to movie alcohol use; and f) using associative latent growth models, investigate relations between alcohol use and violence over time. The analyses will be conducted with controls for a number of covariates that may be correlated with movie exposure (e.g. sensation seeking, parenting style), will examine alcohol exposure effects for participants of different ages, and will test for replicated findings across the two independent studies. The work will be conducted by an interdisciplinary, team with expertise in substance use theory and analytic procedures.

描述（由申请人提供）：了解青少年为何开始饮酒并继续增加饮酒量是防止青少年酗酒的关键因素。尽管众所周知，青少年开始饮酒是为了应对社会影响，但娱乐业的影响仍然没有得到充分研究，而且我们还不知道有研究考察电影对青少年饮酒的影响。我们的初步数据表明，看电影饮酒会影响饮酒的开始。电影中对性行为和暴力的描述与饮酒同时发生可能会产生额外的影响，并且持续接触电影描述可能会影响酒精使用的升级以及可能的其他结果（例如攻击行为）。然而，这些媒体效应的性质尚未在大型代表性样本中得到广泛研究。为了更多地了解电影对青少年酗酒和暴力的影响，我们建议对两 (2) 个数据集进行基于理论的分析，基线均为 10-14 岁青少年：研究 1 是来自涵盖 2415 名新英格兰北部学生的学校样本的 2 波数据集，研究 2 是来自 6522 名 10-14 岁美国青少年的全国代表性样本的 4 波数据集。我们的目标是：a) 检查 1990 年至 2005 年间上映的 1000 多部当代流行电影中关于酒精使用、酒精品牌描述、暴力、性和非法药物使用的内容分析数据； b) 估计青少年在电影中接触这些因素的情况，并检查此类电影接触与青少年饮酒和其他问题行为之间的关系； c) 通过选定的变量（例如性别、种族、自我控制）测试电影曝光效应的调节； d) 通过酒精预期和使用者的认知图像等中介因素，测试电影暴露对青少年饮酒的间接影响； e) 在使用潜在成长模型的纵向分析中，检查青少年态度和行为随时间的变化，作为持续接触电影酒精使用的函数； f) 使用关联潜在增长模型，调查随时间推移饮酒和暴力之间的关系。分析将控制许多可能与电影接触相关的协变量（例如感觉寻求、养育方式），将检查酒精接触对不同年龄参与者的影响，并将测试两项独立研究的重复结果。这项工作将由在物质使用理论和分析程序方面具有专业知识的跨学科团队进行。
