Classes and Stages of Adolescent Alcohol Involvement

描述(由申请人提供)：这是一个修订后的申请，以支持对收集的5个数据集的二次分析，以测试问题行为理论(PBT)以及第六个数据集，即全国青少年健康纵向研究(ADD Health)。拟议分析的目的是经验性地确定青少年酗酒的阶段，并调查导致阶段之间过渡的先前心理社会风险因素。酒精在青春期的各个阶段，如实验性饮酒或重度饮酒，都是随意定义的，而不是根据经验确定的。每个阶段的业务定义多种多样，导致了该领域的混乱。这6个数据集使用了一组一致的酒精行为问题，评估了曾经使用过的酒精行为、饮酒频率、通常的摄入量、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。目的1：潜在类别分析(LCA)将被用来确定最新数据集中青少年酒精参与的经验潜在类别。目的2：将使用早先收集的其他PBT数据集交叉验证由此产生的涉及酒精的潜在类别。目的3：将使用来自五个PBT数据集的数据来检验青少年酒精参与潜在类别结构中的性别、年龄和种族差异。目的4：两个相隔20年的4波PBT数据集将被检验，以描述青少年在这些阶段参与的自然历史。目的5：利用潜伏期分析(LTA)对两组四波PBT数据进行进一步分析，以探讨从一个阶段过渡到另一个阶段的先期危险因素。目的6：将在两个纵向PBT数据集中检查这些阶段先期危险因素的性别差异。目的7：来自全国ADD健康研究的数据将被用来进一步测试青少年饮酒改变的类别和阶段的可重复性。目标8：增加健康数据将用于调查这些类别的种族/民族差异以及不同阶段之间过渡的风险因素。确定青少年酗酒的阶段和在这些阶段之间过渡的风险因素应该有助于在这一人群中设计更有效的预防和干预努力。

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.
