Classes and Stages of Adolescent Alcohol Involvement

描述（由申请人提供）：这是一个修订后的应用程序，用于支持对为测试问题行为理论（PBT）而收集的5个数据集以及第六个数据集（国家青少年健康纵向研究（Add Health））进行的二次分析。建议的分析的目标是建立经验的青少年参与酒精的阶段，并调查由此产生的阶段之间的过渡的先行心理社会风险因素。青春期酒精参与的阶段，如实验性饮酒或大量饮酒，被任意定义，而不是经验确定。每个阶段的各种操作定义导致了该领域的混乱。这6个数据集采用了一组一致的酒精行为问题，评估了饮酒史、饮酒频率、日常摄入量、大量饮酒、醉酒和饮酒的负面后果。拟议的分析涉及以下8个目标。目标1：潜在类分析（LCA）将被用来确定经验的潜在类的青少年参与酒精在最近的数据集。目标2：将使用先前收集的其他PBT数据集交叉验证酒精参与的潜在类别。目标3：性别，年龄和种族的青少年酒精参与的潜在类的结构差异将使用的数据从五个PBT数据集进行检查。目的4：两个4波PBT数据集收集相隔20年将被检查，以描述青少年参与这些阶段的自然历史。目标5：将使用潜在转换分析（LTA）进一步分析两个4波PBT数据集，以研究从一个阶段转换到另一个阶段的先行风险因素。目标6：将在两个纵向PBT数据集中检查这些阶段的前期风险因素的性别差异。目标7：来自国家添加健康研究的数据将用于进一步测试青少年参与酒精的班级和变化阶段的可复制性。目标8：添加健康数据将用于研究这些类别中的种族/民族差异以及各阶段之间过渡的风险因素。建立青少年酒精参与的阶段和这些阶段之间的过渡的风险因素，应有助于设计更有效的预防和干预工作，在这一人群。

DESCRIPTION (provided by applicant): This is a revised application to support secondary analyses of 5 data sets collected to test Problem Behavior Theory (PBT) as well as a sixth data set, the National Longitudinal Study of Adolescent Health (Add Health). The goal of the proposed analyses is to establish empirically the stages of adolescent involvement with alcohol and to investigate antecedent psychosocial risk factors for transitions between the resultant stages. Stages of alcohol involvement in adolescence, such as experimental drinking or heavy drinking, have been arbitrarily defined rather than empirically determined. The variety of operational definitions of each stage has led to confusion in the field. These 6 data sets employed a consistent set of alcohol behavior questions assessing ever use, frequency of drinking, usual intake, high-volume drinking, drunkenness, and negative consequences of drinking. Proposed analyses address the following 8 aims. Aim 1: Latent Class Analysis (LCA) will be employed to determine the empirical latent classes of adolescent involvement with alcohol in the most recent data set. Aim 2: Resultant latent classes of alcohol involvement will be cross-validated using the other PBT data sets collected earlier. Aim 3: Gender, age, and ethnic-racial differences in the structure of the latent classes of adolescent alcohol involvement will be examined using data from the five PBT data sets. Aim 4: Two 4-wave PBT data sets collected 20 years apart will be examined to describe the natural history of adolescent involvement in these stages. Aim 5: The two 4-wave PBT data sets will be further analyzed using Latent Transition Analysis (LTA) to investigate the antecedent risk factors for transitions from one stage to another. Aim 6: Gender differences in the antecedent risk factors for these stages will be examined in the two longitudinal PBT data sets. Aim 7: Data from the national Add Health study will be used to further test the replicability of the classes and stages of change in adolescent involvement with alcohol. Aim 8: Add Health data will be used to investigate racial/ethnic differences in these classes and in the risk factors for transitions among the stages. Establishing the stages of adolescent alcohol involvement and the risk factors for transitions among these stages should facilitate the design of more effective prevention and intervention efforts in this population.
