The Internet may be an effective medium for delivering smoking prevention to children. Consider This, an Internet-based program, was hypothesized to reduce expectations concerning smoking and smoking prevalence. Group-randomized pretest-posttest controlled trials were conducted in Australia (n = 2,077) and the United States (n = 1,234) in schools containing Grades 6 through 9. Australian children using Consider This reported reduced 30-day smoking prevalence. This reduction was mediated by decreased subjective norms. The amount of program exposure was low in many classes, but program use displayed a dose-response relationship with reduced smoking prevalence. American children only reported lower expectations for smoking in the future. Intervening to prevent smoking is a challenge, and this data suggest small benefits from an Internet-based program that are unlikely to be of practical significance unless increased by improved implementation. Implementation remains the major challenge to delivering interventions via the Internet, both for health educators and researchers.
互联网可能是向儿童提供吸烟预防信息的有效媒介。“考虑一下这个”是一个基于互联网的项目，其假设是降低对吸烟的预期和吸烟率。在澳大利亚（n = 2077）和美国（n = 1234）对6至9年级的学校进行了分组随机前测-后测对照试验。使用“考虑一下这个”项目的澳大利亚儿童报告称30天吸烟率有所降低。这种降低是由主观规范的减少介导的。许多班级的项目接触量较低，但项目使用与吸烟率降低呈现剂量反应关系。美国儿童仅报告对未来吸烟的预期较低。干预预防吸烟是一项挑战，这些数据表明基于互联网的项目带来的益处很小，除非通过改进实施来增加效果，否则不太可能具有实际意义。对于健康教育工作者和研究人员来说，实施仍然是通过互联网提供干预措施的主要挑战。
