Testing the Impact of Smartphone-based Messaging to Support Young Adult Smoking Cessation - Pilot

Intervention messages in the proposed trial will address specific high-risk situations for smoking and smoking urges. Messages will focus on two key situational triggers for message matching: 1. Stress (high/low) and 2. Presence of other smokers (yes/no). For each situation, characterized by a combination of these characteristics, several messages were developed. To improve user engagement with the intervention, all messages contain visual content in form of pictures.
