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. |
