Background In order to understand how people perceive, process, and respond to COVID-19 risk information, a valid and reliable instrument is needed. This study aimed to develop an instrument to measure the risk perceptions of people about COVID-19 based on the Extended Parallel Process Model (EPPM). Methods This cross-sectional study was conducted in Tabriz, Iran. First, a comprehensive literature review was conducted to develop the initial draft of Risk-percept COVID-19. Then, in order to obtain a pre-final version of the instrument, face and content validity were conducted. After that, construct validity (exploratory and confirmatory), internal consistency using test-retest reliability and Cronbach’s alpha of the instrument were measured. Results Forty two item were initially generated. During the content validity, it was reduced to 29 items. The exploratory factor analysis (EFA) revealed four factors (perceived response efficacy, perceived threats (severity and susceptibility), perceived self-efficacy, and defensive responses (denial, avoidance and reactance) that accounted for 49.97 of the observed variance. The confirmatory factor analysis (CFA) designated a model with appropriate fitness for the data. Cronbach’s alpha coefficient for the dimensions ranged from .697 to .793, and the Intraclass Correlation Coefficient (ICC) ranged from .71 to .80 within acceptable ranges. Conclusion the current findings show that the Risk-percept COVID-19 is a valid and reliable instrument to assess the cognitions and perceptions of adults. |
