A Meta-Analysis of Smoking Cessation Interventions With Individuals in Substance Abuse Treatment or Recovery.

This meta-analysis examined outcomes of smoking cessation interventions evaluated in 19 randomized controlled trials with individuals in current addictions treatment or recovery. Smoking and substance use outcomes at posttreatment and long-term follow-up (≥ 6 months) were summarized with random effects models. Intervention effects for smoking cessation were significant at posttreatment and comparable for participants in addictions treatment and recovery; however, intervention effects for smoking cessation were nonsignificant at long-term follow-up. Smoking cessation interventions provided during addictions treatment were associated with a 25% increased likelihood of long-term abstinence from alcohol and illicit drugs. Short-term smoking cessation effects look promising, but innovative strategies are needed for long-term cessation. Contrary to previous concerns, smoking cessation interventions during addictions treatment appeared to enhance rather than compromise long-term sobriety.

Initial abstinence and success in achieving longer term cocaine abstinence.

This study's goals were to characterize the relationship between early and longer term cocaine abstinence and assess whether increasing early abstinence increases longer term abstinence. Results from 190 cocaine-dependent outpatients were analyzed. Participants were divided into 2 conditions: (a) those treated with community reinforcement approach (CRA) plus contingent vouchers (n?=?125) and (b) those treated with control treatments (n?=?65). A period of sustained abstinence during treatment was associated with significantly greater odds of posttreatment abstinence, with no evidence of differences between the 2 treatment conditions in that regard. Treatment conditions differed in that CRA plus contingent vouchers increased the proportion of participants who sustained a period of during-treatment abstinence and increased abstinence during 6-month posttreatment follow-up. Devising interventions that increase the proportion of individuals who achieve an early period of sustained abstinence may be key to increasing longer term cocaine abstinence.

Relations between in-treatment and follow-up abstinence among cocaine-dependent homeless persons in three clinical trials.

Clinical trials with cocaine-dependent outpatients have found a strong relation between in-treatment and follow-up abstinence, and the strength of this relation is constant across treatment conditions with variable efficacy in generating abstinence. The authors conducted secondary analyses of data from 3 clinical trials to determine whether this relation generalizes to cocaine-dependent homeless persons. The 3 trials (total N = 543) were conducted in a community health care facility for homeless people. The 7 treatment arms across the 3 trials were combinations of day treatment, abstinence-contingent housing, and vocational training. Drug use was measured with urine toxicology testing. Consecutive weeks of abstinence during treatment were strongly related to abstinence at the 12-month follow-up, whether or not missing 12-month data were included in the analysis. The treatment arms differed in their efficacy in generating abstinence, but the relation between in-treatment and follow-up abstinence did not differ across treatment arms. These results replicate earlier reports of these relations and extend them to a population of homeless people. The lack of differences between treatment arms in the in-treatment–follow-up abstinence relation implies that that relation is independent of the treatment-specific intervention components that generate group differences in abstinence.

How much weight gain occurs following smoking cessation: A comparison of weight gain using both continuous and point prevalence abstinence.

Estimates of postcessation weight vary widely. This study determined the magnitude of weight gain in a cohort using point prevalence and continuous abstinence criteria for cessation. Participants were 196 volunteers who participated in a smoking cessation program and who either continuously smoked (n?=?118), were continuously abstinent (n?=?51), or who were point prevalence abstinent (n?=?27) (i.e., quit at the 1-year follow-up visit but not at others). Continuously abstinent participants gained over 13 lbs. (5.90 kg) at 1 year, significantly more than continuously smoking (M?=?2.4 lb.) and point prevalence abstinent participants (M?=?6.7 lbs., or 3.04 kg). Individual growth curve analysis confirmed that weight gain and the rate of weight gain (pounds per month) were greater among continuously smoking participants and that these effects were independent of gender, baseline weight, smoking and dieting history, age, and education. Results suggest that studies using point prevalence abstinence to estimate postcessation weight gain may be understanding postcessation weight gain.

An investigation of predictors of nicotine abstinence in a smoking cessation treatment study of smokers with a past history of alcohol dependence.

This study investigated predictors for smoking abstinence at 12-week follow-up among 85 smokers with a past history of alcohol dependence enrolled in a smoking cessation trial. Length of alcohol abstinence at time of enrollment and longest previous period of smoking abstinence were significantly associated with smoking status at follow-up. Multiple logistic regression with these variables entered as predictors suggested that longest previous period of smoking abstinence partially mediated the relationship between length of alcohol abstinence at enrollment and smoking status at follow-up. Additional research is warranted to identify predictors of nicotine abstinence and smoking relapse in this population and to understand the factors that mediate the relationship between length of alcohol abstinence at enrollment and smoking outcome.

Sex dfferences in the relation of mood to weight gain after quitting smoking.

Weight gain with smoking cessation is well documented. In this study the authors explored the impact of mood state on weight gain after quitting. Data of 350 participants enrolled in 2 smoking cessation trials were analyzed; primary analyses assessed the relation of affective factors to weight gain in abstinent participants only. Weight gain was predicted by abstinence status. Depression history, gender, and mood change from pre- to postcessation assessments were included in a model predicting weight gain in abstinent participants at the end of smoking cessation treatment (N?=?201) and at 1-year follow-up (N?=?87). At posttreatment, depression history positive women gained more than depression negative women, whereas depression history positive men gained less than depression history negative men. At 1-year follow-up, weight gain was predicted by improved mood in "normal" men and by worsened mood in both depression history positive and negative women.

A controlled smoking cessation trial for substance-dependent inpatients.

Smoking treatment for newly recovering drug and alcohol-dependent smokers in a residential rehabilitation program was examined. The randomly assigned conditions (n?=?50 each) were multicomponent smoking treatment (MST), MST plus generalization training of smoking cessation to drug and alcohol cessation (MST+G), or usual care (UC). Fifty participants who declined smoking treatment (treatment refusers) also were studied. Both treatment conditions achieved continuous smoking abstinence rates (MST: 12%. MST+G: 10%, at 12-month follow-up) that were significantly higher than in the UC condition (0%). The MST condition had a continuous drug and alcohol abstinence rate that was significantly higher than that of the MST+G condition (40% vs. 20% at 12-month follow-up) although neither differed significantly from that of the UC condition (33%). These results support the feasibility of smoking treatment for this population and provide information regarding appropriate treatment components.

Predictors of initial smoking cessation and relapse through the first 2 years of the Lung Health Study.

Analyses were made separately for men and women of the predictors of end-of-treatment (4 months) smoking cessation and subsequent relapse at 12 and 24 months among 3,923 participants enrolled in the Lung Health Study's 12-week cognitive–behavioral group smoking cessation program. Nicotine gum (2 mg) was available to all participants. Men were more likely than women to quit smoking initially, but relapse rates were similar for both genders. Baseline variables associated with initial quitting for both genders included greater education, lower nicotine dependence, and fewer respiratory symptoms. The best predictor of relapse between 4 and 12 months was smoking at least 1 cigarette between quit day and 4 months. Nicotine gum use at 12 months predicted relapse by 24 months for both genders. Greater social and environmental support for quitting smoking were the only factors that predicted both initial quitting and relapse for both genders. Clinical implications are discussed.

Contingency management improves abstinence and quality of life in cocaine abusers.

Contingency management (CM) treatments enhance drug abstinence. This study evaluated whether CM also improves quality of life and if these effects are mediated by abstinence. Across 3 independent trials, cocaine abusers in intensive outpatient treatment (n = 387) were randomly assigned to 12 weeks of standard treatment as usual or standard treatment with CM. The Quality Of Life Inventory (QOLI) was administered at baseline and at Months 1, 3, 6, and 9. Changes in QOLI scores over time differed significantly by treatment, with QOLI scores rising over time in CM participants and remaining stable in standard treatment participants. CM participants also achieved greater durations of abstinence, and duration of abstinence was correlated with posttreatment QOLI scores. During-treatment abstinence mediated the relationship between treatment condition and QOLI scores over time. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The influence of transdermal nicotine on tobacco/nicotine abstinence and the effects of a concurrently administered cigarette in women and men.

Transdermal nicotine (TN) is an efficacious smoking cessation pharmacotherapy thought to work, in part, by attenuating the effects of tobacco/nicotine abstinence and the effects of concurrently smoked cigarettes. Clinical trials suggest that TN may be less efficacious for women. This study explored the possibility of TN-related gender differences in ≥8 hour abstinent smokers (54 women, 70 men) who completed four within-subject, double-blind, placebo-controlled sessions corresponding to 0, 7, 14, and 21 mg TN. In each approximately 6.5-hr long session participants smoked an own-brand cigarette 4 hours after TN administration and physiological and subjective outcomes were examined throughout each session. Results revealed that TN suppressed some signs and symptoms of tobacco abstinence and attenuated some effects of smoking, and these effects were not dependent on gender. Women were more sensitive to the direct effects of nicotine (e.g., ratings of Nauseous) and, independent of TN dose, self-administered less nicotine when smoking and rated smoking as less rewarding. Thus, although this study does not shed light on clinical observations that TN is less effective for women, results suggest that TN might need to be combined with other interventions to supplement its effects on tobacco/nicotine abstinence and concurrent smoking.

Prediction of smoking relapse: Analyses of temptations and transgressions after initial cessation.

Different types of "relapse crises" and associated coping responses were associated with the resumption of smoking using a prospective design. One hundred and two previously heavy smokers (M?=?23.9 cigarettes a day) who achieved initial abstinence through a smoking cessation program were interviewed by telephone at 1, 2, and 3 months posttreatment. At each assessment, subjects described relapse crises, situations in which they were tempted to smoke or actually smoked but resumed abstinence (lapsed). Prospective analyses indicated that any smoking lapse is strongly related to subsequent relapse. Situational characteristics of relapse crises and the number of cognitive and behavioral coping responses reported during crises were only modestly consistent over time and were unrelated to later relapse. Confidence ratings and situational attributions about the relapse crises were also not prospectively associated with eventual relapse. Subanalyses suggested that lapses associated with urges and emotional (guilt) responses and lapses occurring in frequent situations are more likely to result in relapse.

Abstinence violation effect: Validation of an attributional construct with smoking cessation.

The abstinence violation effect (AVE) proposed in Marlatt and Gordon's (1980, 1985) model of smoking relapse was operationalized as a combination of internal, stable, and global causal attributions for smoking a cigarette following the attainment of abstinence from smoking. Causal attributions both for maintaining abstinence and for smoking in hypothetical high-risk situations were obtained prior to quitting from participants in a smoking cessation program. After treatment, subjects who relapsed also provided retrospective causal attributions for initial smoking episodes. Results showed that participants who relapsed following a slip reported significantly higher AVEs (more internal, stable, and global causal attributions) than those who regained abstinence following a slip. Furthermore, the AVE emerged as the strongest predictor of subsequent smoking when included in a discriminant analysis along with other factors associated with the initial smoking episode. Prospective pretreatment attributions for smoking and not smoking in hypothetical high-risk situations were not significantly related to attributions for actual smoking episodes.

Alcoholics Anonymous and Relapse Prevention as Maintenance Strategies After Conjoint Behavioral Alcohol Treatment for Men: 18-Month Outcomes.

Ninety men with alcohol problems and their female partners were randomly assigned to 1 of 3 outpatient conjoint treatments: alcohol behavioral couples therapy (ABCT), ABCT with relapse prevention techniques (RP/ABCT), or ABCT with interventions encouraging Alcoholics Anonymous (AA) involvement (AA/ABCT). Couples were followed for 18 months after treatment. Across the 3 treatments, drinkers who provided follow-up data maintained abstinence on almost 80% of days during follow-up, with no differences in drinking or marital happiness outcomes between groups. AA/ABCT participants attended AA meetings more often than ABCT or RP/ABCT participants, and their drinking outcomes were more strongly related to concurrent AA attendance. For the entire sample, AA attendance was positively related to abstinence during follow-up in both concurrent and time-lagged analyses. In the RP/ABCT treatment, attendance at posttreatment booster sessions was related to posttreatment abstinence. Across treatment conditions, marital happiness was related positively to abstinence in concurrent but not time-lagged analyses. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Programmed therapeutic messages as a smoking treatment adjunct: Reducing the impact of negative affect.

Maintaining treatment gains remains a challenge to smoking cessation programs. Smokers prone to negative affect are most likely to relapse. In an effort to improve maintenance, a standard cognitive behavioral treatment was supplemented with the provision of computer-controlled audiotape players containing personalized therapeutic messages. Either the standard treatment alone or the standard treatment plus 2 months use of the tape player were provided to 41 smokers. No outcome difference was found between the 2 conditions during the 1-year follow-up. (The combined 1-year abstinence rate was 61%, with 34% continuously abstinent.) The frequency with which participants used the device predicted both posttreatment coping skill use and smoking rate. Most notable was an interaction between treatment condition and negative affect. Provision of the devices negated or reversed the usual association between negative affect and poorer outcome. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Weight loss and behavior change 1 year after behavioral treatment for obesity.

Reports a 1-yr follow-up study of 88 of the 1st 108 clients to complete a behavioral weight reduction program at Stanford University's Eating Disorders Clinic. On the average, Ss maintained their in-treatment weight loss over the follow-up period, but there was marked variability and a low correlation between in-treatment and posttreatment performance. Ss reported significant changes in their eating behavior after treatment, but these changes were only weakly related to weight changes.

A preliminary investigation of rapid smoking as a lapse-responsive treatment for tobacco dependence.

Lapses within the first 2 weeks of a smoking cessation attempt are strongly associated with a return to regular smoking (S. L. Kenford et al., 1994). Unfortunately, little is known about how to prevent an initial lapse from progressing to a full relapse, and presently there are no validated lapse-responsive therapeutic interventions. The present study tested the efficacy and feasibility of rapid smoking plus counseling as a novel lapse-responsive intervention. Sixty-seven participants enrolled in a smoking treatment program involving brief counseling and a 9-week course of bupropion. Beginning on the quit day, participants' smoking behavior was tracked daily for 14 days. Once an early smoking lapse was identified, participants were randomly assigned to receive either 3 sessions of rapid smoking plus counseling or no intervention (usual care). Consistent with previous research, participants who smoked during the first 2 weeks of the quit attempt had significantly poorer 6-month outcomes (3% abstinent) than did those who did not smoke (64% abstinent). Compared with early abstainers, early lapsers were more nicotine dependent and reported greater cravings and lower confidence in their ability to abstain from smoking during the first 48 hours of abstinence. As expected, rapid smoking produced a variety of aversive effects, including increased nausea, dizziness, and vomiting as well as sharply decreased cravings to smoke. However, rapid smoking did not improve abstinence outcomes relative to usual care. Although rapid smoking has been shown to be an effective treatment for initial smoking cessation, in this preliminary study the authors failed to demonstrate its effectiveness as a lapse-responsive treatment.

Concurrent brief versus intensive smoking intervention during alcohol dependence treatment.

Alcohol dependent smokers (N=118) enrolled in an intensive outpatient substance abuse treatment program were randomized to a concurrent brief or intensive smoking cessation intervention. Brief treatment consisted of a 15-min counseling session with 5 min of follow-up. Intensive intervention consisted of three 1-hr counseling sessions plus 8 weeks of nicotine patch therapy. The cigarette abstinence rate, verified by breath carbon monoxide, was significantly higher for the intensive treatment group (27.5%) versus the rate for the brief treatment group (6.6%) at 1 month after the quit date but not at 6 months, when abstinence rates fell to 9.1% for the intensive treatment group and 2.1% for the brief treatment group. Smoking treatment assignment did not significantly impact alcohol outcomes. Although intensive smoking treatment was associated with higher rates of short-term tobacco abstinence, other, perhaps more intensive, smoking interventions are needed to produce lasting smoking cessation in alcohol dependent smokers.

Factors associated with participation, attrition, and outcome in a smoking cessation program at the workplace.

Of 66 24–58 yr old smokers in 2 worksites, 67% participated in a smoking cessation program. 55% completed the program. Of those, 29% had quit smoking by posttest, and 17% were abstinent at the 6-mo follow-up. Different variables predicted participation, attrition, and outcome. Significant predictors of smokers who participated were length of cessation in previous abstinence attempts, number of years they smoked, and belief regarding personal vulnerability in contracting a smoking-related disease. Levels of pretest carbon monoxide and attitudes regarding adoption of smoking restrictions in the worksite predicted attrition. Posttest cessation was related to nicotine levels of cigarette brand smoked at pretest and pretest beliefs regarding postcessation weight gain. Abstinence at the 6-mo follow-up was predicted by number of co-workers who smoked and pretest concerns related to postcessation weight gain.

Comparing intervention outcomes in smokers treated for single versus multiple behavioral risks.

This study examined treatment outcomes among smokers with single versus multiple behavioral risks. Data were drawn from smokers (N = 2,326) participating in 3 population-based, multibehavioral studies targeting cigarette smoking, high-fat diets, and high-risk sun exposure. Outcomes were compared for participants at risk for smoking only (13%), smoking plus 1 additional risk factor (37%), and smoking plus 2 additional risk factors (50%). The smoking only group tended to be female, older, more educated, lighter smokers, in the preparation stage of change for smoking, with more previous quit attempts and longer periods of abstinence. At 12 and 24 months follow-up, treatment of 1 or 2 coexisting risk factors did not decrease the effectiveness of smoking cessation treatment, and treatment for the coexisting factors was effective.

Effects of abstinence on cigarette smoking among outpatients with schizophrenia.

The authors of this study examined the effects of brief smoking abstinence on smoking among 6 individuals with schizophrenia or schizoaffective disorder. Before 6 of 12 experimental sessions, participants were required to provide breath carbon monoxide (CO) samples indicative of smoking abstinence; before the remaining sessions, participants provided CO samples indicating no abstinence. During sessions, participants obtained smoking opportunities (2 puffs/opportunity) under either fixed ratio-1 or progressive ratio (PR) schedules of reinforcement. Abstinence increased smoking under both schedules and increased breakpoint for smoking under the PR schedule. These data offer further evidence that smoking by individuals with schizophrenia is orderly, operant behavior that is modulated, at least in part, by variables that also affect smoking in people without major mental illness.
