Some interesting pieces of research about behaviour change and technology: firstly a meta-analysis of online social marketing behaviour change interventions, which concludes that the web works for this kind of thing: "Given the high reach and low cost of online technologies, the stage may be set for increased public health campaigns that blend interpersonal online systems with mass-media outreach." Another study by some of the same researchers looked at the potential for smartphones to deliver alcohol use behaviour change and the availability (or otherwise) of apps for that.
A more recent trial of smoking cessation help delivered by text message also gained positive results. This large UK trial, text2stop, found "significantly improved" smoking cessation levels amongst the recipients of texts.
