- The study focuses on an app-based intervention to reduce smoking urges in young adults using cognitive behavioral therapy (CBT) and mindfulness or acceptance and commitment therapy (ACT) messages.
- A microrandomized trial (MRT) is nested within a conventional between-subject randomized controlled trial (RCT) to test the efficacy of these messages.
- The intervention aims to deliver coping strategies in real-time via smartphones, targeting high-risk situations for smoking.
- The study also explores how substance co-use and specific settings (home, work, bars) may moderate the efficacy of the messages.
- As of June 2025, 58 participants have been enrolled out of a target sample of 160, with 52% in the MRT group and 48% in the EMA-only control group.
- The trial is registered on ClinicalTrials.gov (NCT05836103) and aims to provide evidence on the efficacy of tailored intervention messages for young adult smokers.
