Preparing for the Drug-Free Years (PDFY) is a curriculum designed to help parents learn skills to consistently communicate clear norms against adolescent substance use, effectively and proactively manage their families, reduce family conflict, and help their children learn skills to resist antisocial peer influences. This study examined the effects of PDFY on the trajectories of these factors, as well as on the trajectory of alcohol use from early to mid adolescence. The sample consisted of 424 rural families of sixth graders from schools randomly assigned to an intervention or a control condition. Data were collected from both parents and students at pretest, posttest, and 1-, 2- and 3 1/2-year follow-ups. Latent growth models were examined. PDFY significantly reduced the growth of alcohol use and improved parent norms regarding adolescent alcohol use over time. Implications for prevention and evaluation are discussed.
“无毒品岁月准备计划”（PDFY）是一门课程，旨在帮助家长学习相关技能，以便持续传达明确的反对青少年使用毒品的规范，有效且积极主动地管理家庭，减少家庭冲突，并帮助孩子学习抵制反社会同伴影响的技能。本研究考察了PDFY对这些因素轨迹的影响，以及对从青春期早期到中期饮酒轨迹的影响。样本包括来自随机分配到干预组或对照组学校的424个六年级农村家庭。在预测试、后测试以及1年、2年和3.5年随访时收集了家长和学生的数据。研究了潜在增长模型。随着时间的推移，PDFY显著降低了饮酒量的增长，并改善了家长对青少年饮酒的规范。文中讨论了该研究对预防和评估的意义。
