This study tested the effectiveness of a 10 minute videotape and complementary print program guide on the knowledge and attitudes of junior high school students about blood pressure (BP). A randomized two group pre-test, post-test and delayed post-test design was used. The experimental group received an educational session on BP, designed for this study, which consisted of a 40-minute session, comprised of a 10-minute video presentation and discussion by the teacher on BP (guided by the program guide). The educational session was effective in improving students knowledge of BP at one week post-test; however, this positive effect did not persist at the three month post-test. Student interest in, or knowledge of, their own BP was not obviously affected by the session. The findings were interpreted in light of Social Learning Theory (SLT) and the PRECEDE Model of Health Education (PMHE). In testing the effect of one component of an educational program, i.e., the videotape and teacher lesson the environmental determinants of behaviour change could not be addressed in this study. The educational session was able, however, to achieve the desired knowledge change. The 10-minute videotape and complementary print program guide was shown to be a viable educational tool and can therefore be utilized as a resource in a broader multi-faceted program of cardiovascular (CV) health promotion.
本研究测试了一段10分钟的录像带及配套的印刷版节目指南对初中生血压知识和态度的影响。采用随机两组前后测及延迟后测设计。实验组接受了为本研究设计的关于血压的教育课程，该课程为期40分钟，包括10分钟的视频展示以及教师关于血压的讨论（由节目指南引导）。该教育课程在测试后一周有效地提高了学生的血压知识；然而，这种积极效果在三个月后测时并未持续。该课程对学生对自身血压的兴趣或了解没有明显影响。研究结果依据社会学习理论（SLT）和健康教育前期过程模式（PMHE）进行了解释。在测试教育项目的一个组成部分（即录像带和教师授课）的效果时，本研究无法探讨行为改变的环境决定因素。然而，该教育课程能够实现预期的知识改变。10分钟的录像带及配套的印刷版节目指南被证明是一种可行的教育工具，因此可作为更广泛的多方面心血管（CV）健康促进项目的一种资源加以利用。
