ABSTRACT The purpose of this study was to investigate the effect of digital education by using the Theory of Planned Behavior on the improvement of occupational health and ergonomic conditions of dentists. This Quasi-experimental study, which consisted of two descriptive and quasi-experimental parts, was conducted on 63 dentists in Bojnourd city (Iran) in 2017. The dentists were included in the study through the census method. After identifying the determinants of ergonomic conditions in the descriptive study, the Quasi-Experimental study was undertaken to determine the effect of digital intervention. Data collecting methods were demographics information questionnaire, Nordic questionnaire, a self-administered questionnaire designed in compliance with theoretical constructs and the RULA tool, which were completed before and after the intervention by dentists. More than 97% of the dentists were at high risk of developing skeletal problems. The constructs of subjective norm, perceived control, attitude and behavioral intentions were significant predictors of their ergonomic behaviors (p < 0.001). Results show that there was no significant difference in the mean attitude and knowledge scores between the experimental and control groups before the educational intervention (p = 0.164). But after the intervention, the mean attitude and knowledge scores in the experimental group were significantly different from before the intervention (p < .05). Training based on the (TBP) using digital media was effective in the knowledge and attitude of ergonomic conditions of the dentists. However, it was not effective for behavioral intention.

改善牙医职业健康和人体工程学条件的数字化教育：计划行为理论的应用

摘要 本研究的目的是通过使用计划行为理论研究数字教育对改善牙医职业健康和人体工程学条件的影响。这项准实验性研究由两个描述性和准实验性部分组成，于 2017 年对 Bojnourd 市（伊朗）的 63 名牙医进行。牙医通过人口普查方法纳入研究。在描述性研究中确定人体工程学条件的决定因素后，进行了准实验研究以确定数字干预的效果。数据收集方法是人口统计信息问卷、北欧问卷、按照理论结构和 RULA 工具设计的自我管理问卷，这是在牙医介入之前和之后完成的。超过 97% 的牙医出现骨骼问题的风险很高。主观规范、感知控制、态度和行为意图的构建是其人体工程学行为的重要预测因素（p < 0.001）。结果表明，教育干预前实验组和对照组的平均态度和知识得分没有显着差异（p = 0.164）。但干预后，实验组的平均态度和知识得分与干预前有显着差异（p < .05）。基于（TBP）使用数字媒体的培训在牙医的人体工程学条件的知识和态度方面是有效的。然而，它对行为意图无效。
