DESCRIPTION (provided by applicant): Our studies of American Indian youth, along with those of others, have demonstrated the substantially increased risk among native youth for substance use and other related problem behaviors. Our 25-year tracking of adolescent substance use among American Indians shows that native youth have reported consistently higher rates of substance use than other U.S. ethnic minority groups and White non-Hispanic youth. Because of their increased risk, it is essential to further understand the nature and course of substance use among this population of youth. The overall goal of this center project will be to examine the growth and the trajectories of Indian adolescent substance use over an extended period of time, determining antecedents and outcomes associated with substance use change over time. Considerable research has investigated latent growth and latent class trajectories of alcohol use among youth in general. But such investigation has not been conducted among native youth. Essentially no past research has investigated latent class trajectories for substance use other than alcohol among adolescent youth. We plan to investigate these questions investigating American Indian adolescents using a unique longitudinal sample of American Indian youth and their families. The American Indian Research Center at the University of Washington has conducted a prospective study of American Indian adolescent substance use. The study enrolled both adolescents and their families and conducted annual assessments each year over a nine-year period. A 96% retention rate was achieved over the course of the study resulting in usable data on approximately 500 families. An extensive range of variables were measured including demographic, psychological, behavioral, social, and family domains. Adolescent subjects were followed from a mean age of 11 through a mean age of 19, the age of highest risk for development of alcohol and drug-related adverse consequences. While some use has been made of this data, it has not been analyzed using newer statistical procedures that will allow us to assess growth models of substance use and latent classes of trajectories using growth-mixture models. A number of hypotheses will be testable including identification of substance use trajectories, detection of predictors and consequences of different trajectories, and timing and interactions of specific etiologic factors.

描述（由申请人提供）：我们对美国印第安青年的研究，以及对其他国家的研究，表明土著青年吸毒和其他相关问题行为的风险大大增加。我们对美国印第安人青少年药物使用情况的25年追踪显示，土著青年的药物使用率一直高于美国其他少数民族和非西班牙裔白人青年。由于他们的风险增加，有必要进一步了解这些青年人口中物质使用的性质和过程。该中心项目的总体目标将是在一段较长时间内检查印度青少年物质使用的增长和轨迹，确定与物质使用随时间变化相关的前因和结果。相当多的研究调查了一般青少年酒精使用的潜在增长和潜在阶级轨迹。但这种调查尚未在土著青年中进行。基本上，过去没有研究调查过青少年中酒精以外物质使用的潜在阶级轨迹。我们计划调查这些问题调查美国印第安青少年使用一个独特的纵向样本美国印第安青年和他们的家庭。华盛顿大学的美国印第安人研究中心对美国印第安青少年的药物使用进行了一项前瞻性研究。这项研究招募了青少年和他们的家人，并在九年的时间里每年进行一次评估。在整个研究过程中，96%的保留率达到了96%，产生了大约500个家庭的可用数据。测量了广泛的变量，包括人口统计、心理、行为、社会和家庭领域。青少年研究对象的平均年龄为11岁，平均年龄为19岁，这是产生酒精和毒品相关不良后果的最高风险年龄。虽然已经对这些数据进行了一些使用，但尚未使用更新的统计程序对其进行分析，这将使我们能够评估物质使用的增长模型和使用增长混合模型的潜在轨迹类别。许多假设将是可测试的，包括确定物质使用轨迹，检测预测因素和不同轨迹的后果，以及特定病因因素的时间和相互作用。
