ALCOHOL, PSYCHOSOCIAL FACTORS AND ADOLESCENT DEVELOPMENT

拟议项目的主要目标是测试一个发展模型 青少年药物使用的影响， 使用模式。 它包含了青少年发展的一个关键方面， 青少年个性化的作用。 该模型假设 影响个体化的变量之间的因果关系， 其次是直接和间接的使用。 该车型将 分别适用于三个族裔群体，黑人、墨西哥裔美国人和 盎格鲁人，期望种族差异的个性化和 家庭动力学将对个体化的作用产生独特的影响， 物质使用。 研究1通过问卷调查解决测量问题 对三个民族进行管理。 研究的第一年将 致力于评估1050名青少年和成人， 三个民族的测量可比性。 研究2将使用交叉- 序贯纵向设计和结构方程模型来评估 青少年物质使用的发展沿着青少年 个性化过程 为了最大限度地增加交叉的年份- 第6、7和8天将提供截面和纵向数据 三个种族的年级学生（n=6300）将每年进行三次调查， 连续几年，产生足够大的数据样本LISREL分析。 这项研究的另一个目的是确定心理社会如何 个体化对青少年的影响过程中的变量 物质使用。 在这种情况下，社会人口状况、家庭气氛 和父母关系将被调查

The main objective of the proposed project is to test a developmental model of adolescent substance use that extends current psychosocial interaction models of usage. It incorporates a key aspect of adolescent development , the role of adolescent individuation. The proposed model hypothesizes causal sequences between variables that affect individuation and subsequently usage, both directly and indirectly. The model will be applied separately to three ethnic groups, Black, Mexican-American and Anglo, with the expectation that ethnic differences in individuation and family dynamics will have unique bearing on the role of individuation in substance use. Study 1 addresses measurement issues with questionnaires administered to the three ethnic groups. The first year of the study will be devoted to the assessment of 1050 adolescents and adults to develop triethnic comparability of measurement. Study 2 will use a cross- sequential longitudinal design and structural equation modeling to assess progression of adolescent substance use along with the adolescent individuation process. To maximize the number of years that cross- sectional and longitudinal data will be available, 6th, 7th, and 8th graders in three ethnic groups (n=6300) will be surveyed annually for three successive years, yielding data samples large enough for LISREL analyses. An additional purpose of the study is to determine how psychosocial variables impact the process of individuation in its effects on adolescent substance use. In this context, sociodemographic status, family atmosphere and parental relations will be investigated.
