Investigating mothers’ decisions about their child’s sun-protective behaviour using the Theory of Planned Behaviour

Abstract

This study tested the utility of the theory of planned behaviour (TPB) to predict mothers' decisions to ensure their child engages in sun-protective behaviours. Mothers (N = 162) of children aged 4 or 5 years completed standard TPB items (attitude, subjective norm, perceived behavioural control, intention) and additional variables of role construction, mothers' own sun safe behaviour, planning, and past behaviour. One week later, participants (N = 116) reported their behaviour. Results found support for the TPB constructs, role construction, past behaviour, and the mediating role of planning. These findings can inform strategies to prevent skin cancer during people's lifetimes.
