Outcome Measures

Primary Outcomes (1)

  • expired-air carbon monoxide confirmed 7-day point prevalence smoking abstinence

    expired-air carbon monoxide \< 10 ppm and self report of no smoking for 7 consecutive days prior to assessment

    52 weeks

Secondary Outcomes (1)

  • depression symptoms

    52 weeks

Study Arms (2)

Open Label CBT and Pharmacotherapy

NO INTERVENTION

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.

Behavioral: cognitive behavior therapy

EXPERIMENTAL

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

Behavioral: cognitive behavior therapy

Interventions

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.
