The efficacies of 2 group counseling step-up treatments for smoking cessation, cognitive-behavioral/skill training therapy (CBT) and motivational interviewing/supportive (MIS) therapy, were compared with brief intervention (BI) treatment in a sample of 677 smokers. Differential efficacy of the 2 step-up treatments was also tested in smokers at low and high risk for relapse (no smoking vs. any smoking during the first postquit week. respectively). All participants received 8 weeks of nicotine patch therapy. BI consisted of 3 brief individual cessation counseling sessions; CBT and MIS participants received BI treatment and 6 group counseling sessions. Neither CBT nor MIS treatment improved long-term abstinence rates relative to BI. Limited support was found for the hypothesis that high-risk smokers would benefit more from MIS than CBT. Other hypotheses were not supported.

Gender differences in smoking quit rates are frequently reported and are the subject of much speculation. This study examined the generalizability of gender differences in abstinence across study sites, treatments, and time of relapse, as well as potential mediators and moderators of gender effects. Participants were smokers who participated in 3 randomized clinical trials of the nicotine patch (N = 632). Men had higher cessation rates than women at all follow-ups. The impact of gender on abstinence was unaffected by controlling for study site, treatment, or time of relapse. There was little evidence for mediation or moderation of this relation by any of a host of predictor variables. The magnitude and consistency of the gender differential, coupled with an inability to account for it, highlights a compelling need for additional research specifically aimed at elucidating the relation between gender and abstinence.

Smokers (N = 126) were randomly assigned to 6-session smoking cessation treatments consisting of 1 of 2 counseling strategies (skills training or support) and 1 of 2 nicotine exposure strategies (nicotine gum or rapid smoking). Counseling and nicotine strategies were completely crossed; all four combinations resulted in equivalent 1-year abstinence rates. Skills training produced higher initial cessation and more coping responses posttreatment than did support. Rapid smoking, but not nicotine gum, produced tachycardia to the taste of cigarettes posttreatment, consistent with cigarette aversion. The treatments were differentially effective among subpopulations of smokers: Subjects high in pretreatment negative affect responded best to support counseling; those low in pretreatment negative affect responded best to skills training. Self-reports of pretreatment craving predicted response to the nicotine exposure treatments.
