Oliver JA, et al. – The focus of this study is to estimate the prevalence of smartphone ownership and patterns of use among smokers, as well as the perceived utility of various smartphone application features for smoking cessation that is currently in development or already available. The results seemed to suggest that mobile health interventions have the potential to reach a large number of smokers but are currently under–utilized. However, the additional effort is required to ensure parity in treatment access. The authors suggested that gain–framed messages might be particularly helpful for engaging smokers, even if other features ultimately drive treatment effects.
