Abstract
Introduction:
Location-sensing within smartphone apps could enhance the accuracy and timeliness of behavioural support delivery. We have developed an app (Q Sense) which prompts real-time smoking behaviour reporting leading up to a smoker’s quit date, including psychological and environmental antecedents and geospatial location. When, post quit-date, smokers enter or remain in locations with ≥ 2 smoking reports (a ‘geofence’), the app delivers tailored support. We assessed the app’s acceptability among smokers accessing and not accessing Stop Smoking Services (SSSs).
Methods:
Smokers (N=43) were recruited through GP practices, SSSs, and online advertisements, and invited to use Q Sense pre and 4-weeks post quit-date. Data from three sources were analysed: the app, before and after surveys, and one-to-one interviews, analysed thematically (n=9).
Findings:
Four participants withdrew. Of those followed up (30/39), 74% said they would use the app again, and 76% indicated slight or no privacy concerns. The app was considered a ‘friend’ or a convenient alternative to in-person support. Improvement suggestions included increased support duration and tailoring. The median response time to viewing a location/‘geofence’-triggered support message was 4.5 minutes, significantly quicker than for routine daily messages (p<0.001).
Conclusion:
A context-aware app was perceived as acceptable and beneficial by most smokers
