Abstract
People often behave in ways that harm their health because the short-term rewards are more powerful than the perceived longer-term benefits. Interventions to change such behaviours have had modest effects (NICE, 2007). Interventions will be strengthened by:
• better application of behaviour change theory,
• more precise specification of content in terms of behaviour change techniques
• developing methods for responsively intervening “in the moment†and
• using “optimisation†study designs.
Digital interventions present enormous opportunities advancing the field by allowing tailored “real time†interventions and optimisation designs. If the potential of such opportunities is to be maximised, these opportunities must be underpinned by behavioural science.
This talk will present BCT Taxonomy v1, a method for specifying intervention content, identifying ‘active ingredients’ and making links between techniques and mechanisms of action (theory). This will be illustrated in relation to two smoking cessation interventions:
1. Txt2stop, a mobile phone messaging intervention found to double smoking cessation
2. StopAdvisor, an interactive, theoretically based internet intervention
Preliminary findings will be presented from UBhave, a cross-disciplinary project investigating the power and challenges of using mobile phones and social networking for digitally supported behaviour change. Its aim is to contribute to a scientific foundation for this work (http://ubhave.org/).
