The relationship between growth in adolescent substance use and delinquency was examined in a longitudinal, randomized controlled study of the Preparing for the Drug Free Years Program (PDFY), a universal family-focused prevention intervention. Latent growth curve modeling was used to analyze 5 waves of data collected from 429 rural adolescents. Results showed that adolescents assigned to the PDFY intervention condition had a slower rate of linear increase over time in both substance use and delinquency compared with adolescents assigned to the control condition. Moreover, pretest level of delinquency was a reliable, positive predictor of growth in substance use, whereas pretest level of substance use did not predict growth in delinquency.
在一项针对“无毒品岁月准备计划”（PDFY）的纵向随机对照研究中，探讨了青少年物质使用增长与犯罪行为之间的关系。该计划是一项以家庭为重点的普遍性预防干预措施。采用潜在增长曲线模型分析了从429名农村青少年收集的5波数据。结果显示，与被分配到控制组的青少年相比，被分配到PDFY干预组的青少年在物质使用和犯罪行为方面随时间的线性增长速度较慢。此外，犯罪行为的预测试水平是物质使用增长的可靠正向预测指标，而物质使用的预测试水平并不能预测犯罪行为的增长。
