青少年中吸毒和酗酒的情况仍然普遍较高，但学生在学校接受的预防措施却较少。将健康信息融入核心课程可能是一种有价值的预防方法。因此，行为改变理论被用来为四年级和五年级学生开发毒品科学教育课程，然后使用前测/后测准实验设计进行评估。接触课程与知识的变化相关；其他特征（例如年级水平）也发挥了作用。在预测试中对科学更积极的态度预示着更大的知识变化，而一开始了解较少的学生表现出更大的知识变化。该评估的结果可能支持课程的有效性以及行为改变理论与教育方法相结合的效用。
Drug and alcohol use among youth remains at pervasively high levels, but students are receiving less school-based prevention. Infusing health information into core curricula may be a valuable prevention approach. Therefore, behavior change theory was used to develop a science education curriculum on drugs for fourth- and fifth-grade students, which was then evaluated using a pretest/posttest quasi-experimental design. Exposure to the curriculum was associated with a change in knowledge; other characteristics like grade level also played a role. More positive attitudes toward science at pretest predicted greater knowledge change, and students who knew less at the start showed a greater change in knowledge. Results of this evaluation may support the efficacy of the curriculum and the utility of combining behavior change theory with educational approaches.
