Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this behavioral research study is to create and study a Mindfulness-Based Addiction Treatment (MBAT) for nicotine dependence. Mindfulness is a method to help focus attention on being in the "here and now." It can be learned through training in how to control one's attention. It is usually taught through meditation. The overarching goals of the study are to evaluate the efficacy of MBAT for nicotine dependence and the mechanisms and effects posited to mediate MBAT's impact on abstinence.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This 3-group randomized clinical trial will develop and evaluate a Mindfulness-Based Addiction Treatment (MBAT) for nicotine dependence. Mindfulness reflects a purposeful control of attention and can be learned through training in attentional control procedures.

Current cigarette smokers (N=550; 400 in formal study; up to 80-150 pilot) will be randomly assigned to Usual Care (UC), Standard Treatment (ST) or MBAT. UC will be four 5-10 minute counseling sessions following the problem-solving approach in the Treating Tobacco Use and Dependence Clinical Practice Guideline (Guideline). ST is a standard smoking cessation group program using a problem-solving/coping skills approach. MBAT is a group smoking cessation program derived from Mindfulness-Based Stress Reduction (MBSR) and Mindfulness-Based Cognitive Therapy. MBAT will not alter the basic mindfulness approach used in MBCT and MBSR, but will replace depression-related material with smoking cessation strategies from the Guideline. All participants will receive nicotine patches and self-help materials. MBAT mechanisms and effects will be assessed using "implicit" cognitive psychological measures and computer-administered questionnaires. Participants will be tracked from baseline through 4 (UC) or 8 (ST and MBAT) treatment visits and follow-up visits 1 and 23 weeks post-treatment.

The overarching goals are to evaluate MBAT's efficacy for nicotine dependence and the mechanisms and effects posited to mediate MBAT's impact on abstinence.

Primary specific aims are to:

1. Examine the effects of MBAT on abstinence rates
2. Examine the effects of MBAT on mindfulness/metacognitive awareness, attentional control, smoking automaticity, smoking associations in memory, negative affect, depression, stress, affect regulation expectancies, self-efficacy, withdrawal, and coping across the pre- and post-cessation period, and whether these variables mediate MBAT effects on abstinence.
