Detaljeret beskrivelse

400 adult smokers will be randomized. Our primary goal is to examine the effectiveness of a multi-factor maintenance treatment strategy in promoting longer-term smoking abstinence. All smokers will receive the same "Acute Phase Treatment" that combines nicotine patch, bupropion and intensive self-regulatory skills training. Nicotine patches will be provided for 8 weeks and bupropion and skills training will be provided for of 9 weeks. Participants will then enter a "Maintenance Treatment Phase" during which half (n=200) will receive three individualized relapse prevention training sessions spread over a 12 week period. They will also receive 12 weeks of self-administered RPT administered via written treatment modules. Finally, telephone counseling will be provided in conjunction with an Interactive Voice Response system (IVR) that will allow early detection of smoking "slips" and rapid response by treatment staff. The other half (n=200) will be assigned to a control condition that consists of three counselor-led sessions of "supportive therapy" spread over a 12 week period.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Ingen indgriben: Open Label CBT and Pharmacotherapy
All study participants received 8 weeks of cognitive and behavioral cessation and relapse prevention skills training (CBT) and nicotine patch therapy combined with 9 weeks of bupropion SR therapy. Following open-label, this group received general supportive therapy delivered via four telephone calls made to participants over a 12-week period.
Eksperimentel: Behavioral: cognitive behavior therapy
All study participants received 8 weeks of cognitive and behavioral cessation and relapse prevention skills training (CBT) and nicotine patch therapy combined with 9 weeks of bupropion SR therapy. Following open-label treatment, half the participants received an additional 12 weeks of CBT that combined clinic-based skills training sessions, voicemail monitoring and telephone counseling
Adfærdsmæssigt: cognitive behavior therapy
At each clinic session, staff met with participants individually for 30 minutes to develop cognitive and behavioral skills to resist urges to smoke. Staff used self-efficacy questionnaires to assess participants' confidence in their abilities to resist urges to smoke in specific situations and behavioral worksheets to help participants articulate treatment plans to be used in managing their behavior in these situations without smoking. Those participants randomized to extended CBT continued to work with treatment staff individually on the development and use of cognitive and behavioral cessation and relapse prevention skills. Treatment sessions, lasting approximately 30 minutes, were conducted at the San Jose clinic site at weeks 8, 12, 16 and 20.
