Mindfulness Training for Smoking Cessation

Not Applicable

Completed

• Conditions: Smoking Cessation

• Registration Number: NCT05440903
• Lead Sponsor: University of Southern California

Brief Summary

Participants will complete this study remotely, either at home or at their preferred location using an online platform. The investigators propose to test the effects of a mindfulness training \[MT: Headspace\] intervention compared to a time and attention psycho-education control \[control: TedTalks\] among N=200 adult smokers of a nicotine product. Previous studies suggest that mindfulness training may be beneficial in reducing craving during tobacco abstinence. During the study, participants will complete baseline questionnaires, followed by two weeks of daily MT or control training and self-report on questionnaires assessing affect, cognition, and smoking behavior using Ecological Momentary Assessment (EMA) for remote data capture. Following this two weeks of training, participants will complete a smoking quit attempt and complete daily EMA questionnaires for two weeks. The first day of the smoking quit attempt will include a remote Zoom video session following overnight smoking abstinence. During this session the participants will complete a remote stressor task (Trier Social Stress Test, TSST), and the investigators will collect EMA data on affect and smoking behavior before and after the TSST. One month after the start of the quit attempt, participants will complete a phone call as a follow-up to assess smoking behavior over the previous 30 days, and to complete a debriefing. Study objectives are to test the effect of MT on: (1) smoking lapses during the follow-up periods; and (2) stress (affect, smoking urge, withdrawal symptoms) during the TSST.

Primary Outcome Measures

Name	Time	Method
Smoking Cessation Behavior at 30 days	30 days after start of quit attempt	7-day point prevalence abstinence (i.e., no cigarettes smoked in the previous 7 days). 0=did not smoke; 1=smoked at least one cigarette.
Smoking Cessation Behavior at 14 days	14 days after start of quit attempt	7-day point prevalence abstinence (i.e., no cigarettes smoked in the previous 7 days). 0=did not smoke; 1=smoked at least one cigarette.

Secondary Outcome Measures

Name	Time	Method
Stress-related feelings of "anxious"	1 min before the Trier Social Stress Test (TSST), and +5, +30, +60 min after TSST	visual analog scales of "I feel anxious" using the scale (0="not at all" to 100="extremely"). A higher number indicates greater feelings of "anxious"
App training adherence	14 days after starting app training	Adherence to app use will be calculated as the number of times an individual used the app out of a total of 28 sessions (2 session per day for 14 days). A higher number indicates better adherence.
Stress-related feelings of "relaxed"	1 min before the Trier Social Stress Test (TSST), and +5, +30, +60 min after TSST	visual analog scales of "I feel relaxed" using the scale (0="not at all" to 100="extremely"). A higher number indicates greater feelings of "relaxed"
Stress-related feelings of "urge to smoke"	1 min before the Trier Social Stress Test (TSST), and +5, +30, +60 min after TSST	visual analog scales of "I have an urge to smoke" using the scale (0="not at all" to 100="extremely"). A higher number indicates greater feelings of "urge to smoke"
Stress-related feelings of "stressed"	1 min before the Trier Social Stress Test (TSST), and +5, +30, +60 min after TSST	visual analog scales of "I feel stressed" using the scale (0="not at all" to 100="extremely"). A higher number indicates greater feelings of "stressed"
Cessation Motivation	baseline (start of the study) and 30 days after start of quit attempt	change in motivation to quit (or stay quit) as measured by the Contemplation Ladder, a visual graphic used to select current level of quit motivation (0="no thought of quitting"; 10="taking action to quit"). A higher number indicates greater motivation to quit smoking.
