Both Smoking Reduction With Nicotine Replacement Therapy and Motivational Advice Increase Future Cessation Among Smokers Unmotivated to Quit.

Smokers not currently interested in quitting (N=616) were randomized to receive telephone-based (a) reduction counseling plus nicotine replacement therapy (NRT) plus brief advice to quit, (b) motivational advice plus brief advice, or (c) no treatment. More smokers in the reduction (43%) and motivational (51%) conditions made a 24-hr quit attempt over 6 months than smokers in the no-treatment condition (16%; p ≤ .01), but the 2 active conditions did not differ (p ≥ .05). Similarly, 18%, 23%, and 4% of each condition were abstinent (7-day point prevalence) at 6 months (p ≤ .01). Results indicate smoking reduction using NRT does not undermine cessation but rather increases the likelihood of quitting to a degree similar to motivational advice.

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)     

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)     

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)     

Twelve-Week Outcomes From an Investigation of High-Dose Nicotine Patch Therapy for Heavy Smokers With a Past History of Alcohol Dependence.

This study reports findings from an investigation of the efficacy of high-dose nicotine patch (NP) therapy for heavy smokers with a past history of alcohol dependence. One hundred thirty participants were randomly assigned to 42 mg or 21 mg of transdermal nicotine for 4 weeks, followed by an 8-week dose titration. Follow-up assessments were conducted at 4 and 12 weeks. Differences between dose conditions were nonsignificant, although unexpectedly, outcomes favored participants in the 21-mg NP condition. Nicotine abstinence at follow-up was related to longer length of alcohol abstinence at time of enrollment. Future research should investigate ways to improve smoking quit rates in this population, including more frequent counseling sessions and/or other pharmacotherapies. These investigations should focus primarily on smokers in early alcohol recovery. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

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.

Randomized Clinical Trial of the Efficacy of Bupropion Combined With Nicotine Patch in the Treatment of Adolescent Smokers.

Adolescent smokers (N = 211) were randomized to 1 of 2 groups: (a) nicotine patch plus bupropion SR (sustained release; 150 mg per day) or (b) nicotine patch plus placebo. Group skills training sessions were conducted each week by research staff. Abstinence rates at Weeks 10 and 26 were as follows: (a) patch plus bupropion, 23% and 8%, (b) patch plus placebo, 28% and 7%. Despite the lack of a treatment effect, a large majority of adolescents in both treatment groups reduced their consumption to a few cigarettes per day or less and maintained this reduction over time. Similarly, an examination of survival curves revealed that by the end of treatment many had managed to avoid a return to daily smoking. These findings are encouraging and suggest new avenues for research. For example, treatments of the kind examined in this report, augmented by extended maintenance therapies, may yield higher long-term success rates.

The Influence of Instructions and Nicotine Dose on the Subjective and Reinforcing Effects of Smoking.

Subjective and reinforcing effects of smoking a cigarette were examined within a 2 x 2 modified balanced-placebo design, which manipulated instructions about nicotine content (i.e., told regular nicotine vs. told low nicotine) and actual nicotine dose (given a regular nicotine brand vs. a denicotinized brand). Most ratings of the nicotine content and reward value of cigarettes were higher for those told regular nicotine versus told low nicotine, and for those given regular nicotine versus given low nicotine. Nicotine and instructions did not affect craving, withdrawal, or smoke-reinforced responding, but instructions affected the number of puffs earned for those given low nicotine (i.e., placebo effect). Thus, verbal information (instructions) can influence some responses to smoking consistent with the presence of placebo and antiplacebo effects.

Daily Processes in Stress and Smoking: Effects of Negative Events, Nicotine Dependence, and Gender.

The author used a multilevel daily process design to examine relations among daily negative events, perceived stress, smoking, and smoking urges. The moderating effects of gender and nicotine dependence were also explored. Fifty-one adult community-residing smokers recorded negative events, perceived stress, cigarette smoking, and urges to smoke 4 times daily for 14 days. Analyses of within-person relations showed that participants smoked more cigarettes and experienced more urges to smoke on occasions with higher numbers of negative events and higher levels of perceived stress. These relations were stronger for men than for women. Nicotine dependence did not interact with events or stress in predicting smoking or urges. These findings build on laboratory studies and cross-sectional surveys by showing that in naturalistic settings, occasions with negative events and perceived stress are associated with smoking and urges to smoke.

Use of a Brief Smoking Consequences Questionnaire for Adults (SCQ-A) in African American Smokers.

Purposes of the present study were to (a) examine psychometric properties of a brief Smoking Consequences Questionnaire-Adult (SCQ-A) among an African American sample and (b) explore differences in smoking expectancies across levels of smoking-nicotine dependence. Four hundred eighty-four smokers attending an urban health clinic completed the brief SCQ-A. Maximum likelihood factor extraction with a varimax rotation specifying 9 factors replicated 9 factors of the original SCQ-A. Evidence for the brief SCQ-A's reliability and validity was found. Heavier and/or more dependent smokers had significantly higher scores than lighter and/or less dependent smokers on positive expectancies SCQ-A subscales. Results suggest the brief SCQ-A may be a useful alternative to the full scale SCQ-A. Results also provide evidence for the SCQ-A's validity with African American smokers.

Effectiveness of Payment for Reduced Carbon Monoxide Levels and Noncontingent Payments on Smoking Behaviors in Cocaine-Abusing Outpatients Wearing Nicotine or Placebo Patches.

In a 2-week intervention to reduce cigarette smoking among outpatients in treatment for cocaine addiction, 20 subjects were randomly assigned to a contingent group, receiving monetary vouchers for breath samples with carbon monoxide (CO) levels of 8 ppm or less, or to a noncontingent group, receiving vouchers regardless of CO level. Subjects wore either nicotine or placebo patches in a randomized crossover design. Contingent subjects had significantly lower CO levels and met the 8 ppm target significantly more often than did noncontingent subjects; however, number of cigarettes reported smoked did not differ between groups. Use of nicotine patches resulted in CO levels significantly lower than did use of placebo patches, but levels still exceeded 8 ppm regardless of type of patch. Because contingent reward helped cocaine-dependent smokers achieve nonsmoking CO targets, behavioral antismoking interventions merit continued study in similar populations.

Contingent monetary reinforcement of smoking reductions, with and without transdermal nicotine, in outpatients with schizophrenia.

This study was conducted to examine the effects of contingent monetary reinforcement (CM) for smoking reduction, with and without transdermal nicotine, on cigarette smoking in individuals with schizophrenia. Fourteen outpatients participated in each of 3 conditions: (a) CM combined with 21 mg transdermal nicotine, (b) CM combined with placebo patch, and (c) noncontingent reinforcement combined with placebo patch. Each condition lasted 5 days. Carbon monoxide levels were measured 3 times daily, and nicotine withdrawal symptoms were measured once daily in each condition. Results indicated that CM reduced smoking but that 21 mg transdermal nicotine did not enhance that effect. These results offer further evidence supporting the efficacy of CM for reducing smoking among people with schizophrenia, but higher doses of nicotine replacement therapy, or another pharmacotherapy, may be needed to enhance that effect.

Cognitive Therapy Versus Fluoxetine in Generalized Social Phobia: A Randomized Placebo-Controlled Trial.

Sixty patients meeting Diagnostic and Statistical Manual of Mental Disorders (4th ed.: American Psychiatric Association, 1994) criteria for generalized social phobia were assigned to cognitive therapy (CT), fluoxetine plus self-exposure (FLU + SE), or placebo plus self-exposure (PLA + SE). At posttreatment (16 weeks), the medication blind was broken. CT and FLU + SE patients then entered a 3-month booster phase. Assessments were at pretreatment, midtreatment, posttreatment, end of booster phase, and 12-month follow-up. Significant improvements were observed on most measures in all 3 treatments. On measures of social phobia, CT was superior to FLU + SE and PLA + SE at midtreatment and at posttreatment. FLU + SE and PLA + SE did not differ. CT remained superior to FLU + SE at the end of the booster period and at 12-month follow-up. On general mood measures, there were few differences between the treatments.

Characteristics of Air Force personnel who choose pharmacological aids for smoking cessation following an involuntary tobacco ban and tobacco control program.

Objective: The objective of this study was to compare characteristics of smokers who did and did not report use of cessation aids as part of a tobacco control program in a military setting (n = 8994). Design: The study is a longitudinal epidemiological study where the relationship between smoking status at follow-up and use of pharmacologic aids to quit smoking were assessed. Main Outcome Measures: Smoking cessation, post baseline use of cessation aids to quit smoking. Results and Conclusions: Individuals remaining abstinent were 70% less likely to have used NRT/pharmacological aids compared to those that relapsed. NRT/pharmacological aid users were more likely to report plans to smoke after military training, to have friends who smoke, and to accept a cigarette from a friend. NRT/pharmacological aid users were more likely to believe that using NRT was safer than smoking and to have engaged in harm reduction strategies. Our findings suggest that selection bias related to such characteristics may explain some of the discrepancies between effect sizes reported in efficacy compared to effectiveness studies of NRT and smoking outcomes currently reported in the literature.

Alcohol-Focused Spouse Involvement and Behavioral Couples Therapy: Evaluation of Enhancements to Drinking Reduction Treatment for Male Problem Drinkers.

This study evaluated the effects of alcohol-focused spouse involvement and behavioral couples therapy (BCT) in group drinking reduction treatment for male problem drinkers. Sixty-four male clients and their female partners were randomly assigned to 1 of 3 conditions: treatment for problem drinkers only (PDO), couples alcohol-focused treatment, or the latter combined with BCT. Clients whose partners were included in treatment evidenced fewer heavy drinking days and more abstinent/light drinking days in the year following treatment, relative to PDO clients. The combination of alcohol-focused spouse involvement and BCT yielded no better outcomes than alcohol-focused spouse involvement alone. Drinking consequences, spouse behavioral support for drinking reduction, and relationship satisfaction showed no effects of treatment condition.

Psychiatric disorders in smokers seeking treatment for tobacco dependence: Relations with tobacco dependence and cessation.

Objective: The present research examined the relation of psychiatric disorders to tobacco dependence and cessation outcomes. Method: Data were collected from 1,504 smokers (58.2% women; 83.9% White; mean age = 44.67 years, SD = 11.08) making an aided smoking cessation attempt as part of a clinical trial. Psychiatric diagnoses were determined with the Composite International Diagnostic Interview structured clinical interview. Tobacco dependence was assessed with the Fagerstr?m Test of Nicotine Dependence (FTND) and the Wisconsin Inventory of Smoking Dependence Motives (WISDM). Results: Diagnostic groups included those who were never diagnosed, those who had ever been diagnosed (at any time, including in the past year), and those with past-year diagnoses (with or without prior diagnosis). Some diagnostic groups had lower follow-up abstinence rates than did the never diagnosed group (ps OR = .72, p = .02) and those ever diagnosed with more than one psychiatric diagnosis (OR = .74, p = .03) had lower abstinence rates. The diagnostic categories did not differ in smoking heaviness or the FTND, but they did differ in dependence motives assessed with the WISDM. Conclusion: Information on recent or lifetime psychiatric disorders may help clinicians gauge relapse risk and may suggest dependence motives that are particularly relevant to affected patients. These findings also illustrate the importance of using multidimensional tobacco dependence assessments. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A Lesson in Assigning Homework: Therapist, Client, and Task Characteristics in Cognitive Therapy for Depression.

The majority of professional psychologists use homework in clinical practice, at least on occasion. Are there ways of assigning and reviewing homework that contribute to better treatment outcomes? If so, are these strategies being incorporated into clinical practice? To help answer these questions, the authors used data from S. D. Hollon et al.'s (1992) Cognitive-Pharmacotherapy Treatment Project. Trained coders rated aspects of discussions between therapists (delivering cognitive therapy) and clients (N = 24) during the assignment and review of homework. The authors found that better treatment outcome was associated with specific therapist behaviors (i.e., setting concrete goals and discussing barriers to completing the homework), characteristics of the homework task (i.e., using written reminders of the homework), and client involvement in the discussion.

Effects of transdermal nicotine on symptoms, moods, and cardiovascular activity in the everyday lives of smokers and nonsmokers with attention-deficit/hyperactivity disorder.

The aim of the study was to test the self-medication hypothesis by examining the effects of nicotine in the everyday lives of smokers and nonsmokers with attention-deficit/hyperactivity disorder (ADHD). Fifty-two adults with ADHD (25 abstinent smokers and 27 nonsmokers) participated in a double-blind placebo controlled study with one nicotine patch condition and one placebo patch condition in counterbalanced order. Each condition continued for two consecutive days in which patches were administered each morning. The effects of nicotine on ADHD symptoms, moods, and side effects were assessed with electronic diaries. Cardiovascular activity was recorded with ambulatory blood pressure monitors and physical activity was monitored with actigraphs. Nicotine reduced reports of ADHD symptoms by 8% and negative moods by 9%, independent of smoking status. In addition, nicotine increased cardiovascular activity during the first 3 to 6 hours after nicotine patch administration. The results support the self-medication hypothesis for nicotine in adults with ADHD and suggest that smoking cessation and prevention efforts for individuals with ADHD will need to address both the symptom reducing and mood enhancing effects of nicotine.

Behavior Therapy for Depressed Cancer Patients in Primary Care.

Major depression is a common psychiatric disorder among cancer patients and is associated with psychosocial impairment and decreased quality of life. Although some research has explored psychological interventions with cancer patients, outcome studies investigating the benefits of behavior therapy among cancer patients with well diagnosed depression are nonexistent. The present study was a preliminary clinical trial (n=6) used to assess the effectiveness of a Brief Behavioral Activation Treatment for Depression (BATD) among depressed cancer patients in primary care. Results revealed strong treatment integrity, good patient compliance, excellent patient satisfaction with the BATD protocol, and significant pre-post treatment gains across measures assessing depression, quality of life, and medical outcomes. These gains were associated with strong effect sizes and were maintained at 3-month follow up. BATD may represent a practical primary care treatment that may remedy problems associated with traditional psychosocial interventions. Study limitations and future research directions are discussed.

Project Genesis: Assessing the Efficacy of Problem-Solving Therapy for Distressed Adult Cancer Patients.

The efficacy of problem-solving therapy (PST) to reduce psychological distress was assessed among a sample of 132 adult cancer patients. A second condition provided PST for both the patient and a significant other. At posttreatment, all participants receiving PST fared significantly better than waiting list control patients. Further, improvements in problem solving were found to correlate significantly with improvements in psychological distress and overall quality of life. No differences in symptom reduction were identified between the 2 treatment protocols. At a 6-month follow-up, however, patients who received PST along with their significant other reported lower levels of psychological distress as compared with members of the PST-alone condition on approximately half of the outcome measures. These effects were further maintained 1-year posttreatment. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
