Cue-Provoked Craving and Nicotine Replacement Therapy in Smoking Cessation.

Cue exposure paradigms have been used to examine reactivity to smoking cues. However, it is not known whether cue-provoked craving is associated with smoking cessation outcomes or whether cue reactivity can be attenuated by nicotine replacement therapy (NRT) in clinical samples. Cue-provoked craving ratings and reaction time responses were measured on the 1st day of abstinence among 158 smokers who had been randomized to high-dose nicotine (35 mg) or placebo patch. The nicotine patch reduced overall levels of craving but did not attenuate cue-provoked craving increases or reaction time responses. Cue-provoked craving predicted relapse among participants on the nicotine patch but not among those on placebo. In summary, NRT users could benefit from treatment that attenuates cue-provoked craving. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Meta-Analysis of the Efficacy of Nicotine Replacement Therapy for Smoking Cessation: Differences Between Men and Women.

Gender differences in the efficacy of nicotine replacement therapies (NRTs) were examined in a meta-analytical review of 90 effect sizes obtained from a sample of 21 double-blind, placebo-controlled randomized studies. Although NRT was more effective for men than placebo at 3-month, 6-month, and 12-month follow-ups, the benefits of NRT for women were clearly evident only at the 3- and 6-month follow-ups. Giving NRT in conjunction with high-intensity nonpharmacological support was more important for women than men. That is, NRT and low support were efficacious for women at only short-term follow-up, and men benefited from NRT at all the follow-ups regardless of the intensity of the adjunct support. The results suggest that long-term maintenance of NRT treatment gains decrease more rapidly for women than men. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Assigned Versus Perceived Placebo Effects in Nicotine Replacement Therapy for Smoking Reduction in Swiss Smokers.

In this report, the authors explore the relationships of perceived treatment to outcome in a large, placebo-controlled trial of nicotine replacement treatment for smoking reduction. In the original study (J. F. Etter, E. Laszlo, J. P. Zellweger, C. Perrot, & T. V. Perneger, 2002), which was conducted in French-speaking Switzerland, smokers were randomly assigned to receive nicotine, matching placebo products, or no intervention. At the end of the 6-month study, participants were asked to guess whether they had received nicotine or placebo. In the present analysis, the authors examined the difference in smoking reduction between those who believed they had received nicotine and those who believed they had received placebo. Regardless of actual treatment, smokers who believed they had received nicotine had significantly better outcome than those who believed they had received placebo.

Motivational Enhancement Therapy for Nicotine Dependence in Methadone-Maintained Pregnant Women.

Pregnant women who are dependent on nicotine and illicit substances are at especially high risk for health complications and psychosocial problems. Motivational enhancement therapy (MET) for reducing smoking during pregnancy was compared with standard-care practitioner advice in a 2-group randomized design. Participants were 63 pregnant opioid-dependent smokers seeking substance abuse treatment, methadone maintenance, and prenatal care. At a 10-week follow-up, self-report and biological measures (i.e., CO, cotinine) indicated no differences in smoking between the MET and standard-care groups. However, MET participants were more likely to have moved forward on the stage of change continuum than those in standard care. Intensive treatment for nicotine dependence, environmental interventions, and innovative harm reduction strategies are recommended to address the barriers to quitting observed in this population of pregnant women.

Motivational Interviewing With Personalized Feedback: A Brief Intervention for Motivating Smokers With Schizophrenia to Seek Treatment for Tobacco Dependence.

Individuals with schizophrenia have a much higher prevalence of tobacco smoking, a lower cessation rate, and a higher incidence of tobacco-related diseases than the general population. The initial challenge has been to motivate these individuals to quit smoking. This study tested whether motivational interviewing is effective in motivating smokers with schizophrenia or schizoaffective disorder to seek tobacco dependence treatment. Participants (N = 78) were randomly assigned to receive a 1-session motivational interviewing (MI) intervention, standard psychoeducational counseling, or advice only. As hypothesized, a greater proportion of participants receiving the MI intervention contacted a tobacco dependence treatment provider (32%, 11%, and 0%, respectively) and attended the 1st session of counseling (28%, 9%. and 0%) by the 1-month follow-up as compared with those receiving comparison interventions.

Effects of Transdermal Nicotine During Imaginal Exposure to Anxiety and Smoking Cues in College Smokers.

In a 2 (patch) × 2 (smoking) × 2 (anxiety) mixed design, 52 undergraduate smokers randomly received a nicotine (21 mg) or placebo patch. After a 4-hr nicotine absorption/deprivation period, participants imagined several scenarios varying in cue content: (a) anxiety plus smoking, (b) anxiety, (c) smoking, and (d) neutral. Although smoking urge increased in both the nicotine and placebo conditions after the absorption/deprivation period, those who received the placebo reported significantly greater urge. During the cue reactivity trials, a significant Patch × Smoking × Anxiety interaction effect was observed for urge. However, participants who received nicotine still experienced moderate urges, indicating that nicotine did not attenuate cue-elicited urge. Transdermal nicotine did not diminish anxiety during the absorption/deprivation period or in response to the cues. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
