Cigarette Smoking
Conditions
Brief summary
The purpose of this study is to: Aim I: Test the efficacy of a mindfulness-based text messaging program for smoking cessation ("iQuit Mindfully"), both as a standalone intervention and in combination with in-person counseling; and Aim II: Investigate the mechanisms through which mindfulness training impacts smoking cessation.
Detailed description
This study is a 2 X 2 randomized controlled trial to investigate the effects of the iQuit Mindfully text messaging program, both as a standalone intervention and in combination with in-person counseling (Mindfulness-based Addiction Treatment; MBAT), compared to usual care. Participants will be randomized to one of four groups based on assignment to iQuit Mindfully text messages (yes/no) and in-person MBAT (yes/no): * Usual Care (self-help materials + nicotine patch and nicotine lozenge treatment) * MBAT (8 weekly virtual MBAT sessions + self-help materials + nicotine patch and nicotine lozenge treatment) * iQuit Mindfully (iQuit Mindfully text messages + self-help materials + nicotine patch and nicotine lozenge treatment) * MBAT + iQuit Mindfully (8 weekly virtual MBAT sessions + iQuit Mindfully text messages + self-help materials + nicotine patch and nicotine lozenge treatment) All study participants will receive self-help smoking cessation materials, including the "Clearing the Air" booklet developed by the National Cancer Institute (NCI) and a referral to the Tobacco Cessation Quitline (1-800-QUIT-NOW). All study participants will also receive nicotine patches and lozenges. Assessments will occur at baseline and weeks 1, 3, 5, and 8. Follow-up assessments will occur at weeks 12 and 24.
Interventions
Mindfulness-based Addiction Treatment (MBAT) consists of 8 weekly virtual 2-hour sessions that teach mindfulness and cognitive-behavioral strategies for smoking cessation.
Patch therapy (beginning quit day) for participants who smoke \>10 cigarettes/day will consist of 4 weeks of 21 mg patches, 2 week of 14 mg patches, and 2 week of 7 mg patches. Patch therapy for participants who smoke less than 10 cigarettes/day will consist of 4 weeks of 14 mg patches and 4 weeks of 7 mg patches. Lozenge therapy (beginning quit day) for participants who smoke first cigarette within 30 minutes of waking up will consist of 8 weeks of 4mg lozenges. Lozenge therapy (beginning quit day) for participants who smoke first cigarette 30 minutes of more after they wake up will consist of 8 weeks of 2mg lozenges.
Self-help materials for smoking cessation are based on the Treating Tobacco Use and Dependence Clinical Practice Guideline (Fiore et al., 2008) and include the "Clearing the Air" booklet developed by the National Cancer Institute (NCI) and a referral to the Tobacco Cessation Quitline (1-800-QUIT-NOW).
iQuit Mindfully involves text messages on each day between treatment sessions. The text messages provide mindfulness and cognitive-behavioral strategies and support for smoking cessation.
