A non-probability snowball sample (N = 594) of general public took part in the study via social media. Data were collected at two occasions for one week for each occasion between 30 August 2020 and 26 September 2020. Self-report measures of demographic information and the PMT constructs were obtained at the initial occasion. Two weeks later, self-report measures of COVID-19 preventive behaviours were collected. Structural equation modelling was used for data analysis. The results provided support of the relevance and predictive ability of the PMT. The pattern of effects among the constructs was consistent with the PMT. All of the PMT constructs, with the exception of perceived vulnerability, were found to explain preventive behaviours against COVID-19. Self-efficacy was the strongest variable in predicting the preventive behaviours from COVID-19. Based on these results, public health campaigns that are tailored toward the severity of COVID-19 may be more effective in increasing individualsĄ¯ motivation for adopting COVID-19 preventive behaviours than those that focus on increasing perceptions of individualsĄ¯ vulnerability to COVID-19. Health education interventions should consider strategies to increase an individualĄ¯s perceived self-efficacy of protective behaviours against COVID-19 such as providing opportunities to direct experience with behaviour through demonstration, modelling, and positive feedback. http://pubs.sciepub.com/rpbs/9/1/3/rpbs-9-1-3.pdf COVID-19 protection motivation theory preventive behaviors structural equation modeling Saudi Arabia
