Yksityiskohtainen kuvaus
This study will test a series of hypotheses comparing the efficacy of the relapse prevention treatment to other extended treatments. All participants will be assessed at baseline on demographics, smoking behaviors, nicotine dependence, depression, alcohol and other drug history and problems, mood disturbance, treatment support, stress, health status, and motivation for change. Participants will be randomly assigned to one of four treatment conditions. All participants will receive 12 weeks of combined pharmacological treatment (varenicline) and behavioral treatment (five individual counseling sessions). Following this brief treatment, participants will be randomly assigned to one of four treatment protocols
- Monthly Brief Contact or
- Extended Non-Specific Behavioral Treatment or
- Extended Relapse Prevention Treatment or
- Extended Relapse Prevention Treatment + availability of varenicline treatment.
Each extended treatment protocol is 40 weeks in duration following the initial 12 weeks of treatment.
All participants will be assessed at weeks 12, 24, 52, 64, and 104, on smoking as well as other psychometric measures.

Comparison of Combined Extended vs Brief Treatment at Week 24
Aikaikkuna: 24 weeks following treatment initiation
|
The three extended treatment programs were combined and compared to the Brief treatment, with extended treatments expected to produce significant higher CO corrected abstinence rates overall.
Comparisons will be tested using Chi-Square analysis.
