Behavioral Therapy for Reduction in Smoking Craving

The objective of this pilot research is to investigate the effects of two behavioral smoking cessation programs on aspects of cue-induced cigarette craving, and to further investigate the neural bases of such effects.

The objective of this pilot research is to investigate the effects of two behavioral smoking cessation programs on aspects of cue-induced cigarette craving, and to further investigate the neural bases of such effects. The specific objectives of the study include 1) to investigate the effects of behavioral therapy on cue induced craving using a cognitive task and a fMRI paradigm 2) to pilot test questionnaires and study procedures, and 3) to gather preliminary estimates of the effect size of the novel behavioral therapy for smoking cessation in order to inform the design of a larger trial. A secondary goal of this research is 1) to determine the impact of two cognitive coping techniques on attentional bias to smoking related cues as measured by behavioral responses and patterns of neural activation and 2) to determine the impact of two cognitive coping techniques on cue-induced cigarette craving as measured by self-report and patterns of neural activation. Daily smokers desiring to quit smoking were randomized to one of two behavioral smoking cessation programs: (1) standard cognitive behavioral therapy or (2) mindfulness-based cognitive therapy. Participants completed questionnaires and a brief computer-based cognitive testing paradigm. Participants also underwent a fMRI scan at quit day (week 5). A randomly assigned subset of the participants (n= 18), underwent two additional scans at baseline (week 1) and end-of-therapy (week 8). The study has thus used self-report measures, cognitive testing (Stroop task), and fMRI (functional magnetic resonance imaging) assessments.
