Behaviour change methods, targeted theoretical constructs and implementation strategies

Part	Behaviour change method/s	Implementation strategy	Target construct
1: Education	Information provision	Provide information about the risks of driving into floodwater	Attitudes, risk perception, perceived severity, perceived susceptibility
2: Formation of a goal intention	Personalise risk Scenario-based risk information Provide opportunities for social comparison Goal setting	Providing information about the personal risk; providing reasons people commonly drive into floodwater from prior studies; providing a strategy for overcoming barriers to avoiding driving into floodwater	Intention, attitudes, subjective norm, perceived behavioural control, risk perception, perceived severity, perceived susceptibility, anticipated regret, barrier self-efficacy
3: Practice imagery exercise	Guided practice (imagery skill)	Tangy lemon guided imagery task	Not applicable
4: Process mental simulation	Implementation intentions Goal setting Planning coping responses Guided practice Using imagery	Provide examples of things to do when floodwater is encountered; imagining the steps to use when encountering floodwater while driving; process mental simulation exercise	Intention, perceived behavioural control, barrier self-efficacy, action planning
5: Outcome mental simulation	Personalise risk Information about others’ approval Provide contingent rewards Using imagery	Encouragement to think about the things that can happen when driving into floodwater and when avoiding driving into floodwater, including the risk and the benefits; information about what important others will think; outcome mental simulation exercise	Intention, attitudes, subjective norm, perceived behavioural control, risk perception, perceived severity, perceived susceptibility, anticipated regret
6: Conclusion	Cue altering	Instructing that if ever in the situation to remember goal	Barrier self-efficacy

Part 3 refers to the practice task which is designed to build imagery ability and does not relate to a target construct being assessed.
