Many theories are used to explain and predict human behaviour. Protection Motivation Theory is one of those theories sometimes used by cybersecurity professionals to prepare their programs. Is it a good choice?
Ronald W. Rogers proposed the Protection Motivation Theory (Rogers, 1975) to explain the effect of fear appeal in communications on the audience’s attitude change. Initially, Rogers developed PMT to explain health-related behavioural changes like the impact of fear-appeal on smokers’ behaviour. In 1983, Rogers and Maddux revised the model to include self-efficacy as an influencing factor (Maddux & Rogers, 1983).
PMT suppose an effect of the perceived efficacy of coping response, the perceived self-efficacy to perform the coping response and the probability of the threat on the attitude towards the coping response. We summarised the different variables and their effects in the figure below: Protection Motivation Theory – variables and effects.
PMT is now also used in an information security context by different researchers. As Menard et al. (2017) showed in their literature review on PMT, its application to the information security field gives mixed results.
It was mainly used to explain the impact of threat perception and perceived self-efficacy on changes in security behaviours or attitude in a population (Chou & Sun, 2017; Grimes & Marquardson, 2019; Ismail et al., 2017; Jansen & van Schaik, 2018; Menard et al., 2017; Milne et al., 2009).
If we take the specific case of phishing, these studies did not provide a specific model. Still, they suggest that perceived self-efficacy and threat perception might play a role in the process of detecting phishing emails.
It is an interesting model for health prevention professionals, but probably not for human-centrric cyber security ones.
