Table 2. Illustration of attribute-centred theorizing for the development of behavioural change interventions to reduce prevalence of Guinea-worm disease and cardiovascular diseases.

Attribute-centred theorizing stage	Guinea-worm disease	Cardiovascular diseases
Attribute generation	Required risk reduction behaviours: treating water sources, appropriately disposing of aquatic animal waste, tethering or containment of animals, and identifying and treating infections in humans and animals28	Required risk reduction behaviours: regular fruit and vegetable consumption, regular physical activity, smoking cessation and reduction of salt intake32
	Associated attributes: requirement of technical knowledge, collective benefit, requirement of resources and complexity	Associated attributes: visibility, individual benefit, addictiveness
Attribute testing and verification	Surveys of community members	Social media search
Behavioural matrix construction	e.g. Treatment of water sources may be high for requirement of technical knowledge, high for collective benefit and high for requirement of resources	e.g. Daily consumption of fruits and vegetables may be low for visibility to others, high for individual benefit and low for addictiveness
