NCT00178685

Brief Summary

These two studies will examine the role of autonomous motivation in maintained adherence. The first study will determine whether smokers are still abstinent from tobacco 32 months after starting in a previous project (Smoker's Health Study). The purpose of the second study is to determine which of three treatments for tobacco dependence provides the greatest amount of protection from relapsing to smoking after quitting. Specifically, the investigators will determine if extending the length of treatment time focusing on relapse prevention and arranging for support from important others prevents relapse compared to community care. Also, the investigators will determine if providing extended treatment time and support from important others plus providing medications to those that don't want to quit prevents long term relapse compared to just extending the length of treatment time and support from others. Additionally, a sub set of the population will be randomized to using hand held palm devices to recover real-time data assessment during the last 10 months of the project.

Outcome Measures

Primary Outcomes (1)

  • 12 Month Prolonged Abstinence From Tobacco Measured at 12 Months From Completion of Intervention.

    The primary outcome measure was 12-month prolonged abstinence (12M-PA) assessed by patient self-report 12-months after the intervention ended. If participant responded that they had not smoked a cigarette, even a puff, in the last 7 days at 12 months post-intervention, and reported date of last cigarette was 365 days or more prior to assessment date, then they were considered to have 12 month prolonged abstinence. A baseline-observation-carried-forward (BOCF)strategy was used for missing data such that those not reporting smoking status 12 months post-intervention were considered smoking.

    12 months after subject completes intervention.

Secondary Outcomes (1)

  • 7 Day Point Prevelence (7DPP)

    12 months after the intervention

Interventions

autonomy supported behavioral intervention for tobacco dependent individuals

Limitations and Caveats

A limitation of this study is the low completion rate of smokers enrolling in the study. This increases the chance of accepting the null hypothesis when there may be differences between groups if all smokers had provided their outcomes.
