Behavioral Activation Therapy and Nicotine Replacement Therapy in Increasing Smoking Cessation

PRIMARY OBJECTIVES:

I. To determine the comparative effectiveness of Behavioral Activation Treatment for Smoking (BATS) plus nicotine replacement therapy (NRT) versus standard cessation treatment plus NRT on high reward sensitivity smokers (IRS+) and low reward sensitivity (IRS-) smokers.

II. To identify mediators of the BATS plus NRT treatment effect in IRS- smokers.

OUTLINE: Patients are randomized to 1 of 2 groups.

GROUP I (STANDARD CESSATION): Patients receive NRT patch daily for 8 weeks. Patients receive individual behavioral treatment sessions consisting of behavioral treatment strategies for smoking cessation and health education information over 45 minutes for 8 sessions.

GROUP II (BATS): Patients receive NRT patch daily for 8 weeks. Patients receive individual treatment sessions consisting of standard cessation (SC) strategies and behavioral activation (BA) strategies over 45 minutes for 8 sessions.

After completion of study intervention, patients are followed up at 3 months.

• Reports diagnosis of seizure disorder or a history of neurological illness or closed head injury that in the opinion of the principal investigator (PI) or designated expert(s) feels that it would affect the results of the electroencephalogram (EEG)
• Current use of certain medications:
