Assessing the predictors of adaptive and maladaptive Covid-19 preventive behaviours: an application of protection motivation theory

ABSTRACT

Despite the high death toll of the COVID-19 pandemic, reported rates of adherence to adaptive preventive health behaviours during the early wave of the pandemic were suboptimal for reducing the risk of disease spread. Additionally, some have adopted practices with the intention of preventing infection that have harmful consequences. Protection Motivation Theory (PMT), consisting of perceived vulnerability, severity, response efficacy, and self-efficacy, has been used to predict intentions to engage in behaviours in past pandemics, and can be extended to the COVID-19 outbreak. Three hundred and thirty-three American adults completed a survey in May 2020 through Amazon’s Mechanical Turk. Ten behaviours recommended by the CDC and WHO and two ‘maladaptive’ behaviours presented in the media were selected for investigation. Binary logistic regressions were conducted to assess the impacts of demographic variables and PMT constructs on behaviour frequency. Perceived severity and vulnerability were not significant predictors of behaviour frequency. Behaviour specific response efficacy and self-efficacy were significant predictors of 11/12 (odds ratios: 2.70–6.22) and 10/12 (odds ratios: 2.59–4.64) behaviours, respectively. Age, gender, education, political ideology, perceived severity, and perceived vulnerability were generally unimportant predictors. Beliefs about the effectiveness of the behaviour and one’s ability to carry out that behaviour consistently seem to be more important in predicting how often someone engages in that behaviour than the perceived dangerousness of COVID-19 and one’s believed susceptibility to infection. These results suggest that interventions trying to modulate the likelihood of engaging in preventive behaviours should focus on the effectiveness of these behaviours in reducing risk of spread and the individual’s ability to engage in these behaviours frequently rather than the dangerousness of the COVID-19 pandemic and the individual’s risk of becoming infected.
