The importance of immunization and the necessity of achieving the goals of the immunization expansion plan and the critical role of undergraduate public health students in attaining these goals in the Covid-19 pandemic is evident. The present study aimed at investigating the effectiveness of using online educational videos on practical learning of vaccination in the apprenticeship stage during covid-19 pandemic: a randomized controlled trial.
This experimental study was conducted on 120 students (60 interventions and 60 control groups) at Hamadan University of Medical Sciences during 2019-2020. The intervention included training vaccination skills through educational videos based on self-efficacy theory, which was conducted for two weeks each week in two sessions of two hours for the intervention group using an educational video. A researcher-made questionnaire and a performance checklist were used to collect data. Data were analyzed using SPSS-16 software. Paired t-test, independent t-test, and Chi-square.
The mean age of the subjects was 22.41 years, and most of the participants were female students (80%). There were statistically significant differences between the intervention and control groups regarding knowledge (19.17±0.92 vs. 16.03±3.00; P<0.001), self-efficacy (40.84±3.71 vs 33.45±4.83; P = 0.01), attitude (22.56±2.95vs 20.28±3.25; P = 0.01) and performance (27.92±6.00 vs 22.38±5.40; P = 0.01) after the intervention.
According to the findings of this study, the use of educational videos for undergraduate students of public health during the apprenticeship period has a positive effect on the practical learning of vaccination. However, it seems that in non-critical times, online education along with face-to-face education will be more effective for practical training.
免疫的重要性以及在新冠疫情期间实现免疫扩大计划目标的必要性，以及本科公共卫生专业学生在实现这些目标中的关键作用是显而易见的。本研究旨在调查在新冠疫情期间使用在线教育视频对实习阶段疫苗接种实践学习的效果：一项随机对照试验。
这项实验研究是在 2019-2020 年期间在哈马丹医科大学对 120 名学生（60 名干预组和 60 名对照组）进行的。干预措施包括通过基于自我效能理论的教育视频进行疫苗接种技能培训，干预组每周进行两次、每次两小时的培训，共两周。使用研究者自制的问卷和表现检查表来收集数据。使用 SPSS-16 软件进行数据分析。采用配对 t 检验、独立 t 检验和卡方检验。
研究对象的平均年龄为 22.41 岁，大多数参与者是女学生（80%）。干预组和对照组在知识（19.17±0.92 与 16.03±3.00；P<0.001）、自我效能（40.84±3.71 与 33.45±4.83；P = 0.01）、态度（22.56±2.95 与 20.28±3.25；P = 0.01）和表现（27.92±6.00 与 22.38±5.40；P = 0.01）方面存在统计学差异。
根据本研究的结果，在实习期间为本科公共卫生专业学生使用教育视频对疫苗接种实践学习有积极影响。然而，在非关键时期，在线教育与面授教育相结合可能对实践培训更有效。
