这项研究评估了以学校为基础的预防干预措施（Botvin，G. J. 1996，2000）对物质开始（酒精、烟草和大麻）、期望和拒绝意图的增长轨迹的影响。中西部农村样本（N = 847）提供了三波来自中学生的数据。生长曲线分析表明，干预措施显着减缓了物质起始的增加速度，并显着减缓了拒绝意图的减少速度。干预措施还减缓了负面结果预期的下降速度，尽管显着性水平很小。多组比较表明，初始物质起始水平对拒绝意图增长轨迹的影响在不同条件下有所不同，这表明干预措施降低了早期物质起始水平对拒绝意图随时间变化率的影响。还发现了性别差异，尽管干预措施有效地减缓了两种性别的起始增长率。
This study evaluated the effects of a school-based preventive intervention (Botvin, G. J. 1996, 2000) on growth trajectories of substance initiation (alcohol, tobacco, and marijuana), expectancies, and refusal intentions. A rural midwestern sample (N= 847) provided three waves of data from middle school students. Growth curve analyses demonstrated that the intervention significantly slowed the rate of increase in substance initiation and significantly slowed the rate of decrease in refusal intentions. The intervention also slowed the rate of decrease in negative outcome expectancies, although the significance level was only marginal. A multiple group comparison showed that the impact of initial levels of substance initiation on growth trajectories of refusal intentions differed between conditions, suggesting that the intervention decreased the effect of early substance initiation on the rate of change over time for refusal intentions. Gender differences also were found, although the intervention was effective in slowing the rate of increase in initiation for both genders.
