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），24至26岁， 年龄，将从3,000多名黑人受试者中随机选择， 国家围产期合作项目的费城样本。 广泛的前瞻性数据，收集这些受试者从出生到7岁 岁，并对他们的母亲，将可用于作为 自变量来预测以后的学业失败（从 高中毕业后，职业生涯失败）。 计划从受试者中收集额外的回顾性数据 （1）他们的物质使用/滥用，直到他们辍学，或 到16岁生日，如果他们没有辍学， （2）其他类型的早期生活变量， 可以预测学校和职业失败（即，学校，家庭，同伴 关系、犯罪行为、人格特征和态度）。 未来的学校记录将可从费城学校 区也是。 统计分析将确定是否增加了 学业失败和职业失败的差异， 药物使用/滥用，（除 其他相关预测因子（控制变量），统计学上 显著）。

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).
