To establish the long-term efficacy of a universal internet-based alcohol and cannabis prevention programme in schools.
A cluster-randomized controlled trial was conducted to assess the effectiveness of the Climate Schools: Alcohol and Cannabis Course. The evidence-based course, aimed at reducing alcohol and cannabis use, is facilitated by the internet and consists of 12 novel and curriculum consistent lessons delivered over 6 months.
A total of 764 year 8 students (13 years) from 10 Australian secondary schools were allocated randomly to the internet-based prevention programme (n = 397, five schools), or to their usual health classes (n = 367, five schools).
Participants were assessed at baseline, immediately post, and 6 and 12 months following completion of the intervention, on measures of alcohol and cannabis knowledge, attitudes, use and related harms.
This paper reports the final results of the intervention trial, 12 months following the completion of the Climate Schools: Alcohol and Cannabis Course. The effectiveness of the course 6 months following the intervention has been reported previously. At the 12-month follow-up, compared to the control group, students in the intervention group showed significant improvements in alcohol and cannabis knowledge, a reduction in average weekly alcohol consumption and a reduction in frequency of drinking to excess. No differences between groups were found on alcohol expectancies, cannabis attitudes or alcohol- and cannabis-related harms. The course was found to be acceptable by teachers and students as a means of delivering drug education in schools.
Internet-based prevention programs for school-age children can improve student's knowledge about alcohol and cannabis, and may also reduce alcohol use twelve months after completion.
评估一种普遍适用于学校的基于互联网的酒精和大麻预防项目的长期效果。
采用整群随机对照试验评估气候学校：酒精和大麻课程的有效性。该循证课程旨在减少酒精和大麻的使用，通过互联网进行，并由 12 个新颖且与课程一致的课程组成，在 6 个月内完成。
共有 10 所澳大利亚中学的 764 名 8 年级学生（13 岁）被随机分配到基于互联网的预防计划（n = 397，5 所学校）或他们的常规健康课程（n = 367，5 所学校）。
在干预结束后的基线、即时、6 个月和 12 个月，参与者接受了酒精和大麻知识、态度、使用和相关危害的评估。
本文报告了气候学校：酒精和大麻课程干预试验的最终结果，即干预结束后 12 个月。干预后 6 个月的课程效果已在之前的报告中提及。在 12 个月的随访中，与对照组相比，干预组的学生在酒精和大麻知识方面表现出显著改善，平均每周饮酒量减少，饮酒过量的频率降低。两组在酒精期望、大麻态度或酒精和大麻相关危害方面没有差异。该课程被教师和学生认为是在学校提供毒品教育的一种可接受的方式。
针对学龄儿童的基于互联网的预防计划可以提高学生对酒精和大麻的认识，并且在完成后 12 个月可能会减少酒精的使用。
