About

The purpose of the study is to see if a behavioral intervention known as retrieval-extinction training (RET) might affect craving in response to nicotine cues (e.g., pictures, videos and objects) and smoking behavior in men and women who smoke cigarettes.

Full description

In a recently published NIDA-funded study, the investigators found that lasting reductions in craving and smoking could be achieved with a brief behavioral intervention designed to alter memory processes underlying smoking-related nicotine addiction. The proposed project will replicate and extend these findings by 1) increasing the dose of intervention so as to bolster the observed treatment effects, 2) employing brain imaging methods to identify patterns of brain activity uniquely associated with the intervention and potentially predictive of treatment outcome, 3) extending follow-up period to more completely document the long-term effects of the intervention. Positive findings from this study could lead to the development of brief therapy that will not only improve treatment outcomes for smokers, but also be used in the treatment other substance use disorders and frequently co-occurring comorbidities such as PTSD.

Inclusion and exclusion criteria

Inclusion Criteria

1. Healthy men and women, ages 25 to 65, who have smoked at least 10 cigarettes per day for at least 3 years.
2. Participants must live within a 50-mile radius of the research facility and have reliable transportation.
3. Participants must be willing to abstain from smoking starting the night before the baseline visit, and starting the night before visit 1 and remain abstinent for four consecutive days.
4. Participants must agree to forego any other medication or behavioral treatment for smoking cessation while enrolled in the study (with the exception of the SC Quitline).

Exclusion Criteria

1. Participants who are dependent on substances other than nicotine.
2. Women who are pregnant during the clinical assessment session or either of the fMRI sessions. These participants must agree to notify the study staff if they become pregnant during the study.

191 participants in 2 patient groups

R-E (Retrieval Extinction)

Experimental group

Description:

83 anticipated participants will undergo 3 sessions on consecutive days of the Retrieval Extinction Training (RET) intervention consisting of a 5-minute 'retrieval' smoking-content video followed 10 minutes later by 1 hour of 'extinction' training consisting of four sequences of smoking-related cues (e.g., pictures). Participants will also receive a lab-based smoking-related cue-reactivity experience during the baseline assessment and 24-hour follow-up test.

Treatment:

Behavioral: Retrieval Extinction Training (RET)

NR-E (No R-E)

Other group

Description:

83 anticipated participants will undergo 3 sessions on consecutive days of the control Retrieval Extinction Training (RET) intervention consisting of a 5-minute 'retrieval' non-smoking or neutral-content video followed 10 minutes later by 1 hour of 'extinction' training consisting of four sequences of non-smoking or neutral cues (e.g., pictures). Participants will also receive a lab-based non-smoking or neutral cue-reactivity experience during the baseline assessment and 24-hour follow-up test.

Treatment:

Behavioral: Control Retrieval Extinction Training (RET)
