我们评估了一项旨在防止小学生使用药物、暴力行为和性行为的综合校本计划的5年试验的有效性。我们采用配对、整群随机、对照设计，包括10所干预学校和10所对照学校。五年级学生(N=1714)自我报告了终生药物使用、暴力和自愿性行为。参与的学生的教师报告了学生(N=1225)使用药物和暴力的情况。两水平随机效应计数模型(学生嵌套在学校内)显示，干预学校学生报告的药物使用(RR=0.41；90%可信区间[CI]=0.25，0.66)和暴力(RR=0.42；90%CI=0.24，0.73)显著低于干预学校学生。两水平随机效应二元模型显示，干预学生的性行为较少(优势比=0.24；90%CI=0.08，0.66)。教师报告证实了学生报告数据的影响。剂量反应分析表明，接触该计划至少3年的学生所有负面行为的发生率明显较低。参与该计划的学生的风险相关行为大大减少，这证明了全面的校本计划可以对学生行为产生强大的有益影响。
We assessed the effectiveness of a 5-year trial of a comprehensive school-based program designed to prevent substance use, violent behaviors, and sexual activity among elementary-school students. We used a matched-pair, cluster-randomized, controlled design, with 10 intervention schools and 10 control schools. Fifth-graders (N=1714) self-reported on lifetime substance use, violence, and voluntary sexual activity. Teachers of participant students reported on student (N=1225) substance use and violence. Two-level random-effects count models (with students nested within schools) indicated that student-reported substance use (rate ratio [RR]=0.41; 90% confidence interval [CI]=0.25, 0.66) and violence (RR=0.42; 90% CI=0.24, 0.73) were significantly lower for students attending intervention schools. A 2-level random-effects binary model indicated that sexual activity was lower (odds ratio=0.24; 90% CI=0.08, 0.66) for intervention students. Teacher reports substantiated the effects seen for student-reported data. Dose-response analyses indicated that students exposed to the program for at least 3 years had significantly lower rates of all negative behaviors. Risk-related behaviors were substantially reduced for students who participated in the program, providing evidence that a comprehensive school-based program can have a strong beneficial effect on student behavior.
