Quit With Sense: Using Mindful Smoking and Wearable Device for Smoking Cessation

Overview

This pilot randomized controlled trial will test the feasibility of a smoking cessation intervention using mindful smoking practice and a smartphone-based sensor-band among adults who regularly smoke cigarettes. Participants will be randomized to either an intervention group or a control group. Participants in the intervention group will receive a one-on-one mindful smoking guidance session, instructions for using a smartphone-based sensor-band, a mindfulness practice video, and smoking cessation information. Participants in the control group will receive smoking cessation information. The intervention period will last 8 weeks, with assessments at baseline, 8 weeks, and 4 months after completion of the intervention. The study will evaluate feasibility, preliminary smoking cessation outcomes, and physiologic parameters including heart rate variation, skin temperature, resting heart rate, respiratory rate, and real-time heart rate during craving and mindful smoking practice.

Cigarette smoking is a leading preventable cause of morbidity and mortality and contributes to cancer, lung disease, health care costs, and reduced quality of life. Although many adults who smoke cigarettes attempt to quit, long-term cessation rates remain low. Mindfulness-based strategies may help people who smoke manage cravings by increasing awareness of present-moment thoughts, emotions, and physical sensations without automatically reacting by smoking. This pilot randomized controlled trial will evaluate a smoking cessation intervention that combines mindful smoking practice with use of a smartphone-based sensor-band. The study will enroll 30 adults who regularly smoke cigarettes and are motivated to quit smoking or make a quit attempt. Participants will be randomly assigned to an intervention group or a control group, with approximately 15 participants in each group. Participants in the intervention group will receive a one-hour, one-on-one, in-person mindful smoking guidance session from a certified mindfulness instructor. The session will teach participants to manage cravings mindfully using the RAIN method: Recognize, Accept, Investigate, and Note. Participants will also receive a mindfulness practice video for home practice and in-person instruction from a research assistant on use of the smartphone-based sensor-band. During the 8-week self-management and intervention period, participants in the intervention group will be instructed to practice mindful smoking when they feel a craving to smoke. They will be asked to record their craving level, duration of mindful smoking practice, feelings after mindful smoking, heart rate at the time of craving, heart rate at the end of mindful smoking practice, and daily cigarette smoking activities. Participants in the control group will receive smoking cessation information published by the American Lung Association, including printed smoking cessation materials. Control group participants will be asked to record their daily cigarette smoking activities. Data will be collected at baseline, 8 weeks after the intervention begins, and 4 months after the intervention is completed. Feasibility will be assessed by recruitment rate, time to recruit the target sample, intervention uptake rate, attrition rate, and participant satisfaction. Preliminary effectiveness will be assessed by 8-week and 4-month smoking abstinence rates and smoking reduction. Smoking abstinence will be confirmed using exhaled carbon monoxide measurement. The study will also assess stress level, self-control and management level, mindfulness level, heart rate variation, skin temperature, resting heart rate, respiratory rate, and real-time heart rate during craving and mindful smoking practice.
