Evaluation of the Effect of Educational Interventions on Knowledge, Attitude, and Practice Against COVID-19 in a Residential Complex in Tehran: A Prospective Cross-sectional Study.

BACKGROUND

The coronavirus disease 2019 (COVID-19) pandemic at the end of 2019 posed a global health concern. It has been found that health education is one of the best methods for health promotion, changing inappropriate personal behaviors, and increasing people's awareness and attitude through major health concerns, including the COVID-19 pandemic. This study aimed to investigate the effect of educational interventions with environmental health approach on the knowledge, attitude, and practice of people in the COVID-19 epidemic era in one residential complex in Tehran.

METHODS

This cross-sectional study was conducted in Tehran in 2021. The study population was households of a residential complex in Tehran, which was selected by a random sampling method. A researcher-made checklist was used to gather data for this study, and its validity and reliability in the domains of environmental health and knowledge, attitude, and practice in the COVID-19 setting were evaluated before it was used. An intervention was made through social media and the checklist was reevaluated after the intervention.

RESULTS

A total number of 306 participants were enrolled in this study. In the assessment of the knowledge, attitude, and practice after the intervention, the mean score of the mentioned values increased significantly ( < 0.001). However, the influence of intervention was more prominent in the improvement of knowledge and attitude than practice.

CONCLUSION

Public health intervention with an environmental health approach can increase people's knowledge, attitude, and practice against chronic diseases and epidemics such as COVID-19.
