Feasibility and Efficacy of a Brief Mindfulness-Based Smoking Intervention Delivered via the Internet: A Randomized Controlled Trial.

Background: A growing body of literature suggests that mindfulness-based interventions are effective in reducing smoking. However, existing mindfulness interventions are often lengthy and require extensive interaction with a therapist, making them inaccessible to a large percentage of the population. The current study addressed this issue by testing the feasibility and efficacy of a single session, web-based, mindfulness intervention for smoking cessation. Methods: Participants (N = 80) took part in a fully online cue exposure exercise interspersed with brief instructions on how to cope with cravings for cigarettes. All participants were randomly assigned to receive either mindfulness-based or coping as usual instructions. Outcomes included participant satisfaction with the intervention, self-reported craving following the cue exposure exercise, and cigarette use 30 days post-intervention. Results: Participants in both groups found the instructions moderately helpful and easy to understand. Participants in the mindfulness group reported a significantly smaller increase in craving than those in the control group following the cue exposure exercise. Averaging across conditions, participants reported smoking fewer cigarettes in the 30 days following the intervention than in the 30 days prior, however there were no between group differences in cigarette use. Conclusion: Mindfulness-based interventions for smoking reduction can be effectively implemented in a brief, single-session online format. These interventions are easy to disseminate and can reach a large number of smokers with minimal participant burden. Results from the current study suggest that mindfulness-based interventions can help participants control craving in the face of smoking-related cues, although perhaps not change smoking quantity. Future research is needed to explore factors which may increase the efficacy of online, mindfulness-based interventions for smoking cessation, while still maintaining their accessibility and reach.
