This study evaluates the impact of video-based approaches on health education. PUBMED, Web of Science, EMBASE, CENTRAL, and LILACS databases were searched from their inception until November 2022. Randomised controlled trials (RCTs) and non-randomized studies on interventions were included in this review. Studies were grouped according to their reported learning outcomes. A random effects meta-analysis was performed. Meta-regression analyses were used to explore the effects of confounding variables on the overall estimates. Forty studies were included in this meta-analysis. The results showed that video-based learning (VBL) has a significant effect on 'knowledge acquisition' in dentistry (Cohen's d = 2.18), moderate effect in medicine (Cohen's d = 0.67); moderate effect on 'skills development' in medicine (Cohen's d = 0.76) and nursing (Cohen's d = 0.59); overall moderate effect on 'attitude' (Cohen's d = 0.74). Egger's test was performed to assess potential publication bias. VBL offers a valuable educational tool for knowledge acquisition, skill development, and attitude changes in health education. The theoretical and practical implications of these findings are also discussed. To strengthen the evidence base, future research should address the limitations found, such as the high risk of bias (RoB), and employ rigorous study designs when investigating the role of multimedia learning in various academic disciplines.
本研究评估了基于视频的方法对健康教育的影响。从成立之初到 2022 年 11 月，我们在 PUBMED、Web of Science、EMBASE、CENTRAL 和 LILACS 数据库中进行了搜索。本综述纳入了随机对照试验（RCT）和干预措施的非随机研究。研究根据其报告的学习结果进行分组。进行了随机效应荟萃分析。Meta 回归分析用于探索混杂变量对总体估计的影响。这项荟萃分析纳入了 40 项研究。结果表明，基于视频的学习（VBL）在牙科领域的“知识获取”方面具有显著效果（Cohen's d=2.18），在医学领域具有中度效果（Cohen's d=0.67）；在医学（Cohen's d=0.76）和护理（Cohen's d=0.59）领域具有中度效果；在“态度”方面总体效果中等（Cohen's d=0.74）。进行了 Egger 检验以评估潜在的发表偏倚。VBL 为健康教育中的知识获取、技能发展和态度转变提供了一种有价值的教育工具。还讨论了这些发现的理论和实践意义。为了加强证据基础，未来的研究应解决发现的局限性，例如高偏倚风险（RoB），并在研究多媒体学习在各个学科中的作用时采用严格的研究设计。
