DRUG USE/ABUSE AS PREDICTOR TO SCHOOL AND CAREER FAILURE

600名黑人受试者(300名男性；300名女性)，年龄在24至26岁之间 年龄，将从3000多名黑人受试者中随机选择 国家合作围产期项目的费城样本。 广泛的前瞻性数据，收集了从出生到七岁的这些受试者 年龄，以及他们的母亲，将可用作 预测未来学业失败的独立变量(辍学 高中，到后来的职业失败)。 计划从受试者那里收集更多的回溯性数据 关于：(1)他们的药物使用/滥用，直到他们退出，或以上 到他们16岁生日时，如果他们没有退学，就会预测会下降 高中毕业；以及(2)其他类型的早期生活变量， 可能会预测到学业和职业失败(例如，学校、家庭、同龄人 关系、犯罪行为、人格特征和态度)。 未来的学校记录将从费城学校获得 学区也是如此。 统计分析将确定是否有额外的 学业失败和职业失败的差异由以下因素解释 物质使用/滥用，(除了 其他相关预测因素(控制变量)，是统计上的 意义重大)。

A sample of 600 Black subjects (300 male; 300 female), 24 to 26 years of age, will be selected by randomization from over 3,000 Black subjects of the Philadelphia sample of the National Collaborative Perinatal Project. Extensive prospective data, collected on these subjects from birth to seven years of age, and on their mothers, will be available for use as independent variables to predict to later school failure (dropping out from high school, and to later career failure). Additional retrospective data is planned to be collected from the subject on: (1) their substance use/abuse, up to the time they dropped out, or up to their 16th birthday, if they did not drop out, to predict to dropping out of high school; and (2) on other types of earlier life variables that might predict to school and career failure (i.e., school, family, peer relationship, delinquent behavior, personality traits and attitudes). Prospective school records will be available from the Philadelphia School District as well. Statistical analyses would determine whether the amount of additional variance in school failure, and in career failure, accounted for by substance use/abuse, (in addition to the variance accounted for by the other relevant predictors (control variables), is statistically significant).
