Classes and Stages of Adolescent Alcohol Involvement

描述（由申请人提供）：这是一份修订后的申请，以支持对5个数据集的二次分析，这些数据集收集用于测试问题行为理论（PBT），以及第6个数据集，国家青少年健康纵向研究（Add Health）。所提出的分析的目的是根据经验确定青少年参与酒精的阶段，并调查由此产生的阶段之间过渡的先决社会心理风险因素。青春期酒精参与的阶段，如实验性饮酒或重度饮酒，都是随意定义的，而不是经验确定的。每个阶段操作定义的多样性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、通常摄入量、大量饮酒、醉酒和饮酒的负面后果。建议的分析涉及以下8个目标。目的1：潜在类别分析（LCA）将被用来确定最近数据集中青少年参与酒精的经验潜在类别。目的2：使用先前收集的其他PBT数据集交叉验证酒精相关的潜在类别。目标3：性别、年龄和种族在青少年酒精参与的潜在类别结构上的差异将使用来自五个PBT数据集的数据进行检查。目的4：将对相隔20年收集的两个4波PBT数据集进行检查，以描述青少年在这些阶段参与的自然历史。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，以调查从一个阶段过渡到另一个阶段的先决风险因素。目标6：这些阶段的先前危险因素的性别差异将在两个纵向PBT数据集中进行检查。目标7：来自国家健康增加研究的数据将用于进一步测试青少年参与酒精的类别和阶段变化的可重复性。目标8：增加健康数据将用于调查这些阶层的种族/民族差异以及各阶段之间过渡的风险因素。确定青少年酗酒的阶段和这些阶段之间过渡的危险因素，应有助于在这一人群中设计更有效的预防和干预工作。

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.
