To test whether baseline levels of the factors accountable for the impact of the Prevention of Alcohol use in Students (PAS) intervention (self-control, perceived rules about alcohol and parental attitudes about alcohol), moderate the effect of the intervention. A cluster randomized trial including 3,490 Dutch early adolescents (M age=12.66, SD=.49) and their parents randomized over four conditions: 1) parent intervention, 2) student intervention, 3) combined intervention and 4) control group. Moderators at baseline were used to examine the differential effects of the interventions on onset of (heavy) weekly drinking at 34-month follow-up. The combined intervention was only effective in preventing weekly drinking among those adolescents who reported to have lower self-control and more lenient parents at baseline. No differential effect was found for the onset of heavy weekly drinking. No moderating roles of self-control and lenient parenting were found for the separate student and parent interventions regarding the onset of drinking. The combined intervention is more effective among adolescents with low-self control and lenient parents at baseline, both factors that were a specific target of the intervention. The relevance of targeting self-control in adolescents and restrictive parenting is underlined.
为了检验预防学生饮酒计划（PAS）干预措施中可归因于影响的因素（自我控制、对饮酒的感知规则和父母对饮酒的态度）的基线水平是否会影响干预效果，我们进行了一项包含 3490 名荷兰早期青少年（M 年龄=12.66，SD=.49）及其父母的整群随机试验，将他们随机分为四个组：1）家长干预组，2）学生干预组，3）联合干预组和 4）对照组。在基线时使用调节变量来检验干预措施对 34 个月随访时（重度）每周饮酒起始的差异影响。只有在那些基线时报告自我控制能力较低和父母较为宽容的青少年中，联合干预才对每周饮酒的发生有预防作用。对于重度每周饮酒的起始，没有发现差异。对于单独的学生和家长干预措施，在饮酒起始方面，自我控制和宽容型教养方式的调节作用均不明显。在基线时自我控制能力较低且父母较为宽容的青少年中，联合干预措施更有效，而这两个因素都是干预的特定目标。这突出了针对青少年自我控制和限制型教养的重要性。
