Strengthening Instrumental Extinction to Prevent Smoking Relapse
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The central objective of the project is to evaluate the effect of incorporating smoking related contexts into very low nicotine content (VLNC) cigarette extinction trials on clinically relevant, smoking-related outcomes. Adult smokers interested in quitting smoking (N=80) will be interviewed and trained to take pictures where they smoke cigarettes. Following taking these pictures, participants will then be switched to smoke VLNCs while wearing a 21 mg/d nicotine patch (EXT) for three weeks. During this 3-week treatment period, half of the sample (n=40) will be randomly assigned to undergo six, 60-minute sessions of multiple context extinction (MCE+) during which they will view smoking-related environments and smoke their assigned cigarettes. The remaining 40 participants will undergo control MCE (exposure to nature environments; MCE-) and smoke their assigned cigarettes. At the end of the three weeks, participants will quit smoking and continue to wear the nicotine patch while being followed during a 10-week abstinence period. Participants will also complete a follow-up phone call 6 months after their quit day.
