Application of the Extended Planned Behavior Theory to Predict COVID-۱۹ Preventive Behaviors

Aims: Preventive behaviors play an important role in reducing mortality caused by this disease. This study aimed to determine the application of the extended theory of planned behavior to predicting preventive behaviors against COVID-۱۹. Instrument & Methods: In this descriptive-analytical cross-sectional study, ۴۱۶ university students were selected and examined through virtual networks through convenience and snowball sampling methods. The data collection tool was developed by the researcher-made questionnaire based on the extended theory of planned behavior. Data were analyzed using descriptive statistics and correlation test and linear regression by SPSS ۱۸ software. Findings: A positive and significant correlation was observed between the mean of all the studied theoretical constructs with preventive behaviors against COVID-۱۹ (p<۰.۰۱). Attitudes, subjective norms, perceived behavioral control, and perception of others' behavior predicted ۴۳% of behavioral intention variance. Moreover, behavioral intention perceived behavioral control and perception of others’ behavior predicted ۵۶% of preventive behaviors variance against COVID-۱۹. Behavioral intention, attitude, perception of others' behavior, subjective norms, and perceived behavioral control had the greatest impact on COVID-۱۹ preventive behaviors. Conclusion: The extended theory of planned behavior can be used as an appropriate framework in designing educational interventions to promote preventive behaviors against COVID-۱۹.
