Location, location, location! An application of situational action theory to phone use while driving in different environments

Situational action theory (SAT) is a comprehensive theory that explains offending behaviour from the context of the interaction between interpersonal factors, such as morals, self-control, and habits, with situational factors, such as environmental risk and social conditions. Illegal hand-held mobile phone use while driving (MPUWD), a prevalent and risky road behaviour, has yet to be examined under the SAT framework. Therefore, by utilising SAT, this exploratory study sought to investigate the interpersonal and situational factors preceding hand-held MPUWD in three distinct road environments (highways, built-up areas and stopped-at-traffic lights). To achieve this, Queensland drivers aged over 18 who owned a mobile phone (N = 821, M_age = 41.7 years, SD = 20.9 years) were invited to complete an online survey. Repeated measures ANOVAs demonstrated significant mean differences for participants’ perceived risks associated with MPUWD and subsequent likelihood of offending across the three environments, with traffic lights being more conducive to MPUWD behaviours. Three hierarchical multiple linear regressions also revealed that age, attitude, risk of judgement, and self-control were significant predictors of MPUWD across all environments, while the results for gender, risk of injury and risk of being apprehended varied across the different driving contexts. Together, these factors explained 38.5–39.6 % of the variance in the perceived likelihood of illegally engaging in MPUWD. Overall, the findings indicated that the application of SAT has predictive utility in determining MPUWD engagement and can provide a more comprehensive framework for approaching and intervening in MPUWD behaviour.
