Descrizione
Inclusion Criteria:
- Participants must be able to provide informed consent and function at an intellectual level sufficient to allow accurate completion of all assessment instruments.
- Participants must meet DSM-IV criteria for current nicotine dependence and be a daily cigarette smoker of 10+ cigarettes/day for a minimum duration of three years.
- Participants must live within a 50-mile radius of the research facility and have reliable transportation.
- Participants must be willing to make a quit attempt beginning the night before the three consecutive daily laboratory sessions (i.e., two retrieval-extinction training sessions and the test session performed 24-hours after the second retrieval-extinction training session).
- Participants must be willing to (a) be overnight smoking abstinent (CO verified) prior to the baseline smoking cue reactivity assessment, and (b) make a cessation attempt and be smoking abstinent (CO verified) over the three day period that corresponds to the two retrieval-extinction training sessions and the test session performed 24-hours after the second retrieval-extinction training session.
- Participants must be willing to submit to a breathalyzer (alcohol) assessment and urine drug screen (for benzodiazepines, methamphetamine, cocaine, marijuana and opiates) and produce a negative test result on (a) the day of the baseline smoking cue reactivity assessment, and (b) each of the three consecutive days that correspond to the two retrieval-extinction training sessions and the test session performed 24-hours after the second retrieval-extinction training session.
- Participants must consent to random assignment to the R-E vs. NR-E conditions.
- Participants must not use smokeless tobacco.
- Participants must be willing to forego any other medication or behavioral treatment for smoking cessation during their enrollment in this study (with the exception of a referral, upon request, to the SC Quitline). Treatment referral will be provided at the end of the study.
Exclusion Criteria:
- Participants with current/active (untreated) psychotic disorder, current major depressive disorder (severe), bipolar affective disorder or a severe anxiety disorder as these conditions would likely interfere with their ability to fulfill the requirements for successful participation (e.g., provide accurate interview data, complete study assessments, attend scheduled laboratory visits, etc.).
- Participants meeting DSM-IV criteria for substance dependence (other than nicotine) within the past 60 days.
- Participants who are unwilling or unable to maintain abstinence from alcohol and other drugs of abuse (benzodiazepines, methamphetamine, cocaine, marijuana and opiates) in order to comply with Inclusion Criterion f above.
- Participants currently taking ß-blockers, anti-arrhythmic agents, psychostimulants or any other agents known to interfere with heart rate, skin conductance or blood pressure responses.
- Current use of any pharmacotherapy or psychotherapy for smoking cessation.
- Pregnant women (because pregnancy can influence responding during study procedures).

Altro: Retrieval-Extinction: Smoking Cues
A relatively brief exposure to cues prior to conducting more protracted cue exposure.
This is referred to as retrieval-extinction training.

Mean of the Difference in Nicotine Craving between Visits 1 and 2
Lasso di tempo: Multiple times points during Visits 1, 2 and 3 (the two retreival sessions and the first test session) as well as the 2-week and 4-week follow-up laboratory test sessions.
|
A craving questionnaire and mood form is given to participants to complete at several time points throughout the visit to access nicotine craving.

Change in Nicotine Use at 2-Week Follow-Up
Lasso di tempo: A diary is given to participants to record their smoking behaviors everyday for two weeks.
|
At the end of the first (24-hr.)
and second (2-wk) test session, participants will receive a smoking diary in which to record the occurrence of (a) daily smoking behavior, and (b) daily craving rating over the ensuing 2-week follow-up period.
