Strategies to influence factors of behavioural change

Factors of behavioural change	Strategy
Awareness factors knowledge, risk perception and cues to action	Educating participants on their current CVD risk factors, with regard to their size and changeability (risk communication). Thereafter, translating this to behavioural change in their personal situation. Raising awareness by providing personal and normative behavioural feedback following motivational interviewing techniques.
Predisposing factors genetic predisposition, current lifestyle, personal characteristics and information factors.	Tailoring the communication of CVD risk factors and lifestyle counseling to the genetically predisposed risk of the participants and their personal characteristics (age, gender, members of the household) and their current lifestyle behaviour. A multi-channel approach is chosen, thereby offering the intervention by internet, face-to-face and by telephone.
Motivational factors attitude, social influence and self-efficacy	Giving personal feedback to participant's self-reported attitude and self-efficacy and by involving the social environment of the participant in making action plans.
Ability factors,	Stimulating participants to make action plans and discussing how to overcome possible barriers in behavioural change, thereby following motivational interviewing techniques.
