Training by Multimedia Messaging Service Method, a Solution to Improve Knowledge, Attitude, and Performance of Health Workers: A Quasi-Experimental Study

Background: Since health workers are the leading providers of health services, increasing their knowledge and performance can play an essential role in preventing diseases, especially Coronavirus Disease 2019 (COVID-19).Objectives: The current research was conducted to compare the effects of lecture training and Multimedia Messaging Service (MMS) training on health workers’ knowledge, attitude, and performance in preventing COVID-19.Methods: This quasi-experimental study was conducted in two groups with a pretest-posttest design. The study population included 60 health workers in Nikshahr selected by random sampling. The data collection tool was a researcher-made questionnaire, including demographic questions and items on health workers’ knowledge, attitude, and performance in preventing COVID-19, completed in two training groups by lecture and MMS methods online before and after the intervention.Results: The participants’ mean score of knowledge increased significantly after training in both lecture and MMS methods (P 0.050), but no significant difference was observed between the two methods (P 0.050). The mean attitude score in the two groups before and after the intervention showed no significant difference (P 0.050). In the performance dimension, a significant difference was observed between the two groups post-intervention, and this score significantly increased in the MMS group (P 0.050).Conclusion:  Considering the effect of the MMS method on health workers’ knowledge and performance, this method can be considered a suitable solution to meet the growing demand for training.
