Addressing the public health problem of physical inactivity, this study evaluates SNapp, a just-in-time adaptive app intervention to promote walking through dynamically tailored coaching content. It assesses SNapp's impact on daily steps and how users' perceptions regarding ease of use and usefulness moderated its effectiveness. ⋯ SNapp increased steps only in users who deemed the app useful, underscoring the importance of user perceptions in app-based interventions.

Ignition interlock devices installed after conviction for driving under the influence of alcohol (DUI) have been shown to reduce subsequent DUI arrests (specific deterrence). However, there is little evidence on how interlock-device penalties might affect general deterrence, that is, deterring people from driving after consuming alcohol prior to a DUI conviction. ⋯ Wider use of interlock devices as a DUI penalty could have large deterrent effects, independent of their ability to physically prevent the motor vehicle of an intoxicated driver from starting. The deterrent effect documented here adds to evidence on interlock devices' overall effectiveness as well as their potential to shift DUI penalties away from criminalization (jail time) and toward immobilization and rehabilitation.

This study examines the prospective association between financial strain and smoking cessation and smoking relapse among U.S. adults with established smoking. ⋯ The results from this study suggest that financial strain is a barrier to cigarette smoking without relapse, which may be due to stress and coping processes. Smoking cessation interventions would benefit from considering the role that financial strain plays in inhibiting smoking cessation without relapse.
