Overview
This study used an intensive longitudinal, two-arm RCT design to study smoking-related cognitions over a three-week period. After a seven-day baseline phase, participants were randomized to use either standard HWL, or modified HWL that were enhanced with efficacy messages. Participants were given a supply of adhesive HWLs specific to the group to which they were allocated and then continued to monitor their smoking and smoking-related cognitions for an additional 2 weeks. In addition to the real-world monitoring, participants attended a total of three in-person laboratory visits. The study received ethical approval from the Human Research Ethics Committee (Tasmania) Network (Ethics Reference Number: H0015696) and written informed consent was obtained from all participants.
