Smoking cessation in homeless populations: a pilot clinical trial.

This study, which tested two motivational interviewing treatment approaches, assessed the feasibility of conducting a community-based smoking cessation intervention among homeless smokers. Participants (N = 46) were recruited from multiple facilities in the Kansas City area and were randomized to two counseling conditions in which they received five individual motivational interviewing sessions, six group meetings, and their choice of 8 weeks of 21-mg nicotine patch or 4-mg nicotine lozenge. The two counseling conditions consisted of motivational interviewing targeted either to smoking behaviors exclusively (smoking only) or to smoking and other addictions or life events that could affect ability to quit (smoking plus). Group meetings were designed to provide educational information and social support. Measures of feasibility assessed included the proportion of participants who returned for randomization among those eligible, adherence to prescribed nicotine replacement therapies, retention rates at the week 26 final study visit, and biochemically verified 7-day abstinence at week 26. Most participants (69.6%) chose nicotine patches, and 32% of those participants reported using at least four patches per week. Carbon monoxide verified 7-day abstinence rates in the smoking-only and smoking-plus groups were 13.04% and 17.39% (ns), respectively, at week 8 and 8.70% and 17.39% (ns), respectively, at week 26. Participants who used at least four patches per week were more likely to have quit at 8 weeks than were those who used fewer patches (33.3% vs. 10.5%, p = .30). Results support the feasibility of conducting a smoking cessation intervention among homeless smokers. Findings also show promising effects for nicotine replacement therapy and counseling in this population. Developing programs to improve smoking cessation outcomes in underserved populations is an essential step toward achieving national health objectives and for ultimately reducing tobacco-related health disparities.     

Are Latinos really less likely to be smokers? Lessons from Oregon.

Our objective was to identify factors associated with current cigarette smoking among Latino adults in Oregon. We used data from 1,356 Latino participants and, for comparison, 18,593 non-Latino White participants in the 2000-2002 Oregon Behavioral Risk Factor Surveillance System (BRFSS). The BRFSS is a random-digit-dialed, cross-sectional survey of noninstitutionalized, English- or Spanish-speaking adults who live in Oregon households with a telephone. We examined relationships between current smoking and gender, age, education, and survey language (a measure of acculturation) among Latinos and used the .05 level of significance. The prevalence of current smoking was significantly lower among Latinos (18.1%) than non-Latino Whites (20.8%). Latino men were significantly more likely than Latina women to be smokers (23.1% vs. 11.4%), and some evidence indicated that less education was associated with smoking among Latino men. Taking the survey in English was strongly and significantly associated with smoking among Latina women: Smoking prevalence was 20.5% among those taking the survey in English and 3.3% for those taking it in Spanish. Our results suggest that the lower smoking prevalence among Latinos was driven by Latina women taking the survey in Spanish. Hence, it is essential for tobacco control programs to examine their local Latino smoking prevalence by gender and acculturation to avoid incorrectly concluding that Latinos are at decreased risk. Although programs for Latinos should reinforce protective aspects of Latino culture, decreasing the smoking prevalence in the U.S. mainstream culture might mitigate the negative impact of acculturation on smoking behaviors.     

Do u smoke after txt? Results of a randomised trial of smoking cessation using mobile phone text messaging

Objectives: To determine the effectiveness of a mobile phone text messaging smoking cessation programme. Design: Randomised controlled trial Setting: New Zealand Participants: 1705 smokers from throughout New Zealand who wanted to quit, were aged over 15 years, and owned a mobile phone were randomised to an intervention group that received regular, personalised text messages providing smoking cessation advice, support, and distraction, or to a control group. All participants received a free month of text messaging; starting for the intervention group on their quit day to assist with quitting, and starting for the control group at six months to encourage follow up. Follow up data were available for 1624 (95%) at six weeks and 1265 (74%) at six months. Main outcome measures: The main trial outcome was current non-smoking (that is, not smoking in the past week) six weeks after randomisation. Secondary outcomes included current non-smoking at 12 and 26 weeks. Results: More participants had quit at six weeks in the intervention compared to the control group: 239 (28%) v 109 (13%), relative risk 2.20 (95% confidence interval 1.79 to 2.70), p < 0.0001. This treatment effect was consistent across subgroups defined by age, sex, income level, or geographic location (p homogeneity > 0.2). The relative risk estimates were similar in sensitivity analyses adjusting for missing data and salivary cotinine verification tests. Reported quit rates remained high at six months, but there was some uncertainty about between group differences because of incomplete follow up. Conclusions: This programme offers potential for a new way to help young smokers to quit, being affordable, personalised, age appropriate, and not location dependent. Future research should test these findings in different settings, and provide further assessment of long term quit rates.     

Computer-tailored smoking cessation intervention in a general population setting in Germany: outcome of a randomized controlled trial.

This study reports the outcome of a randomized controlled trial testing a computer-tailored smoking cessation intervention based on the transtheoretical model in a general population setting in Germany. Participants of the smoking intervention study were recruited from an existing general population health examination survey in a university hospital. The sample consisted of 611 current and former smokers at baseline, and of 485 participants in the core group of baseline daily cigarette smokers. Follow-ups were conducted 6, 12, 18, and 24 months after baseline. The intervention was designed for both current and former smokers, involved up to three individualized feedback letters, and was created using expert-system technology. Based on 7-day point-prevalence abstinence and 6-month prolonged abstinence as the outcome measures, the study identified no significant differences between the intervention and control groups. Modeling the full longitudinal data in generalized estimation equation analyses, using different nonresponse procedures, and adjusting for covariates did not alter the results. We conclude that the computer-tailored transtheoretical model-based smoking cessation intervention, as delivered in this study and in this special setting, was ineffective.     

A cluster randomised controlled trial of smoking cessation in pregnant women comparing interventions based on the transtheoretical (stages of change) model to standard care

Objectives: To evaluate the effectiveness in helping pregnant women stop smoking of two interventions (Pro-Change for a healthy pregnancy) based on the transtheoretical model of behaviour change (TTM) compared to current standard care.

Design: Cluster randomised trial.

Setting: Antenatal clinics in West Midlands, UK general practices.

Participants: 918 pregnant smokers

Interventions: 100 general practices were randomised into the three trial arms. Midwives in these practices delivered three interventions: A (standard care), B (TTM based self help manuals), and C (TTM based self help manuals plus sessions with an interactive computer program giving individualised smoking cessation advice).

Main outcome measures: Biochemically confirmed smoking cessation for 10 weeks previously, and point prevalence abstinence, both measured at 30 weeks of pregnancy and 10 days after delivery.

Results: There were small differences between the TTM arms. Combining the two arms, the odds ratios at 30 weeks were 2.09 (95% confidence interval (CI) 0.90 to 4.85) for 10 week sustained abstinence and 2.92 (95% CI 1.42 to 6.03) for point prevalence abstinence relative to controls. At 10 days after delivery, the odds ratios were 2.81 (95% CI 1.11 to 7.13) and 1.85 (95% CI 1.00 to 3.41) for 10 week and point prevalence abstinence respectively.

Conclusions: While there is a small borderline significant increase in quitting in the combined intervention arms compared with the controls, the effect of the intervention is small. At 30 weeks gestation and at 10 days postnatal, only about 3% of the intervention groups achieved sustained cessation, with numbers needed to treat of 67 (30 weeks of gestation) and 53 (10 weeks postnatal) for one additional woman to achieve sustained confirmed cessation. Given also that the intervention was resource intensive, it is of doubtful benefit.

     

Do social support interventions ("buddy systems") aid smoking cessation? A review

OBJECTIVE: To provide an overview of the role of social support in smoking cessation and to critically review evidence regarding the use of "buddy systems" (where smokers are specifically provided with someone to support them) to aid smoking cessation. DATA SOURCES: Studies were located by searching Medline and Psyclit using the key words "smoking", "smoking cessation", "social support", and "buddy". Additional studies were identified through reference lists. Only studies reported in English and published since 1980 were included. STUDY SELECTION: Studies were selected on four criteria: publication in a peer reviewed journal; randomised controlled trial using smokers who wanted to stop; the use of a social support intervention, including a "buddy"; dependent variable of smoking abstinence. Most research in this area does not use a randomised design so only a small proportion of the originally identified studies were included. DATA SYNTHESIS: In view of the diverse nature of the studies, a meta-analysis was not attempted. Ten studies were identified: nine were clinic based smoking trials, eight used a group format, and nine used buddies from among smokers' existing relationships. Support training varied from role play and rehearsal to a simple instruction to call each other regularly. Intervention and follow up periods varied between studies. Two studies showed a significant benefit of the intervention in the short term. CONCLUSIONS: Research methodology in many cases was poor. The evidence would suggest that in the context of a smokers clinic the use of buddies may be of some benefit. There is a lack of evidence regarding the efficacy of the use of buddies in community interventions. This is an important area for future research.     

Expressive writing as a smoking cessation treatment adjunct for young adult smokers.

This investigation evaluated the efficacy of expressive writing as a treatment adjunct to a brief office smoking cessation intervention plus nicotine patch therapy in young adults. Participants aged 18-24 years were randomized to a brief office intervention (n=99) or to an expressive writing plus brief office intervention (n=97). Both conditions received four individual visits plus 6 weeks of nicotine patch therapy, which began on the quit date following the week 2 visit. Participants in the expressive writing plus brief intervention condition wrote for 2 consecutive days before and 3 consecutive days after the quit date. The brief office intervention group completed a control writing assignment. At end of treatment (week 8), biochemically confirmed 7-day point-prevalence abstinence for the expressive writing plus brief office intervention condition was significantly greater than for the brief office condition (33% vs. 20%, p=.043, OR=2.0, 95% CI=1.0-3.7, from a logistic regression adjusting for gender). At 24 and 52 weeks, abstinence rates were similar for the brief office intervention versus expressive writing plus brief office intervention (12% vs. 11% at 24 weeks; 11% vs. 11% at 52 weeks). The results suggest that expressive writing has promise as a smoking cessation treatment adjunct for young adults. Lengthier interventions or the use of boosters should be tested to extend treatment effects. However, participants reported a low level of enthusiasm for the expressive writing, which may be a barrier to implementing it over a longer time frame. Therefore, other modes of delivering expressive writing to young adult cigarette smokers should be explored.     

Spirometry as a motivational tool to improve smoking cessation rates: a systematic review of the literature.

Obtaining spirometric testing and providing those results to individuals who smoke has been advocated as a motivational tool to improve smoking cessation. However, its effectiveness is not known. We conducted a systematic review to determine if this approach improves rates of smoking cessation. Data sources included MEDLINE (1966 to October 2005), the Cochrane Library, and experts in the field. Eligible randomized controlled trials (RCTs) enrolled at least 25 smokers per arm, evaluated spirometry with associated counseling or in combination with other treatments, followed subjects at least 6 months, and provided smoking abstinence rates. Results from nonrandomized studies also were summarized. The primary outcome was patient-reported long-term (at least 6 months) sustained abstinence with biological validation. Additional outcomes included self-reported abstinence and point-prevalence abstinence. Seven RCTs (N = 6,052 subjects) met eligibility criteria. Follow-up duration ranged from 9 to 36 months. In six trials, the intervention group received concomitant treatments previously demonstrated to increase cessation independently. The range of abstinence was 3%-14% for control subjects and 7%-39% among intervention groups, statistically significantly in favor of intervention in four studies. The only RCT that assessed the independent contribution of spirometry in combination with counseling demonstrated a nonsignificant 1% improvement in patient-reported point-prevalence abstinence at 12 months in the group that received spirometry plus counseling versus counseling alone (6.5% versus 5.5%). Findings from observational studies were mixed, and the lack of controls makes interpretation problematic. Available evidence is insufficient to determine whether obtaining spirometric values and providing that information to patients improves smoking cessation compared with other smoking cessation methods. Spirometric values are of limited benefit as a predictor of smoking cessation or as a tool to "customize" smoking cessation strategies.     

Use of nicotine replacement therapy in socioeconomically deprived young smokers: a community-based pilot randomised controlled trial

Background

Smoking is common in young people, particularly in disadvantaged groups, and continued smoking has a major impact on quality and quantity of life. Although many young smokers want to stop smoking, little is known about the design and effectiveness of cessation services for them.

Objective

To determine whether nicotine replacement therapy (NRT) when combined with counselling is effective in young smokers in a deprived area of Nottingham, UK

Methods and subjects

We surveyed smoking prevalence and attitudes to smoking and quitting in young people accessing an open access youth project in a deprived area of Nottingham, and used the information gained to design a community based smoking cessation service incorporating a randomised controlled trial of nicotine patches against placebo given in association with individual behavioural support. We resurveyed smoking prevalence among project attendees after completing the pilot study.

Results

Of 264 young people surveyed (median age 14 years, range 11–21), 49% were regular smokers. A total of 98 young people were recruited and randomised to receive either active nicotine patches on a six week reducing dose regimen (49 participants), or placebo (49 participants). Adherence to therapy was low, the median duration being one week, and 63 participants did not attend any follow up. At four weeks, five subjects receiving active NRT and two receiving placebo were abstinent, and at 13 weeks none were. Adverse effects were more common in the active group but none were serious. Smoking prevalence among 246 youth project attendees surveyed after the trial was 44%.

Conclusions

This study suggests that NRT in this context is unlikely to be effective in young smokers, not least because of low adherence to therapy. It also suggests that young smokers want help with smoking cessation, but that establishing the efficacy of smoking cessation services for young people who need them most will be very difficult.     

Menthol cigarettes and smoking cessation during an aided quit attempt.

Menthol may make cigarettes more addictive and rates of menthol cigarette smoking are disproportionately higher among Black. However, few studies have examined the association between menthol cigarette smoking and cessation, and the studies to date have produced conflicting findings. The present study examines the effect of menthol cigarette smoking on cessation among a multi-ethnic sample of smokers making a pharmacotherapy-aided quit attempt. We hypothesized that menthol cigarette smoking would be associated with lower smoking abstinence rates and conducted a secondary analysis of data from a multi-site randomized controlled trial of an intervention designed to facilitate repeat tobacco cessation treatment (N = 1,343). The intervention consisted of a patient phone call and a computerized provider prompt. The primary outcome for this analysis was 7-day point prevalence smoking abstinence. The average age of the sample was 56 years old. Overall, 25% of the sample smoked menthol cigarettes: 19% of Whites, 62% of Blacks, and 25% of other ethnicity (p<.001). We observed no significant effects for menthol cigarette smoking or ethnicity on smoking abstinence rates. In conclusion, combined with findings from previous research, this study suggests that smoking menthol cigarettes does not decrease smoking cessation among older smokers during a quit attempt aided with pharmacotherapy.     

Transdermal nicotine use in postmenopausal women: does the treatment efficacy differ in women using and not using hormone replacement therapy?

This study of postmenopausal female smokers (N = 94) asked: During short-term smoking abstinence, do the beneficial effects of transdermal nicotine replacement therapy (NRT) on acute symptomatology (i.e., withdrawal, cigarette craving, smoking urges, mood, depressive symptoms, motor speed, and reaction time) differ in women who use and do not use hormone replacement therapy (HRT)? Participants were recruited according to HRT and non-HRT use (self-selecting), then randomized within strata to active nicotine or placebo nicotine patch. After 1 baseline week of smoking, participants quit smoking for 2 weeks. Women received cessation counseling and were monitored for abstinence. Dependent measures were collected during five clinic visits. Two-way analysis of covariance (ANCOVA) were run on change scores for dependent variables, with nicotine patch group (active/placebo) and HRT group (HRT/non-HRT) as independent variables and age as a covariate. No interactions were found between HRT and patch condition, but both showed specific effects. During the first abstinent week, women on active nicotine patch (compared with placebo) experienced less severe withdrawal, greater reductions in cigarette cravings, and lower (more favorable) Factor 1 scores on the Questionnaire of Smoking Urges. During the second abstinent week, women using HRT (compared with the non-HRT group) exhibited better mood (Profile of Mood States scores) and less depression (Beck Depression Inventory scores). These results suggest the following: First, the efficacy of transdermal nicotine replacement is not adversely modified by women's HRT use; second, ovarian hormones might influence women's responses to smoking cessation, and thus should be considered in developing effective strategies for women to quit smoking.     

International Quit and Win 1996: comparative evaluation study in China and Finland

OBJECTIVES: To compare background and process variables, as well as follow up status, of the participants in the International Quit and Win '96 contests of China and Finland, and analyse factors contributing to sustained maintenance. DESIGN: A standardised 12 month follow up was conducted in both countries with random samples of participants. The sample sizes were 3119 in China and 1448 in Finland, with response rates of 91.2% and 65.2%, respectively. INTERVENTIONS: The International Quit and Win '96 contest was the second coordinated, multinational smoking cessation campaign targeted at adult daily smokers. Altogether 25 countries participated, including China with 15 000 and Finland with 6000 smokers registered. MAIN OUTCOME MEASURES: Conservative (considering all non-respondents relapsed) and non-conservative (based on respondents only) estimates were calculated for one month abstinence, 12 month continuous abstinence, and point abstinence at the time point of follow up. RESULTS: Great differences were found in the background and process variables, as well as in the outcome measures. At one year follow up, the conservative continuous abstinence rates show that the Chinese participants maintained their abstinence better (38%) compared to the Finnish ones (12%). In China women reached higher abstinence rate (50%) than men (36%), whereas in Finland men achieved a better result (14%) than women (9%). CONCLUSIONS: The Quit and Win contest is a mass smoking cessation method feasible in countries showing great variance in smoking habits and rates. However, in countries with different stages of anti-smoking development, such as China and Finland, different practical implementation strategies may be needed.     

Increase in common cold symptoms and mouth ulcers following smoking cessation

Design: Smokers were assessed one week before stopping smoking (baseline), then after one, two, and six weeks of smoking abstinence.

Participants: 174 smokers attending a seven week smoking cessation programme combining behavioural support with nicotine patches.

Main outcome measures: Self reports of cold symptoms, mouth ulcers, and smoking abstinence (validated using expired carbon monoxide) were recorded on each measurement occasion.

Results: Following one, two, and six weeks of smoking abstinence 73.0% (127/174), 57.5% (100/174), and 44.8% (78/174) of the participants, respectively, maintained continuous abstinence and provided reports of cold symptoms and mouth ulcers. For those abstinent from smoking for six weeks, relative to baseline, a significant increase in reports of the number of cold symptoms was observed following one and two weeks of smoking abstinence (p = 0.009 and p = 0.038, respectively) and an increase in reports of mouth ulcers after one and two weeks of abstinence (p = 0.004 and p = 0.008, respectively). Following one week of abstinence significant increases in reports of sore throat, coughing, deafness, and sneezing were observed (p = 0.049, p < 0.001, p< 0.039, and p < 0.003, respectively).

Conclusions: This is the first study to systematically document significant increases in cold symptoms and mouth ulcers following smoking cessation. Smokers should be informed that they have an increased chance of experiencing these symptoms on stopping smoking. Being psychologically prepared for these effects may reduce their impact on the attempt to stop smoking.

     

Designing smoking cessation services for school-age smokers: A survey and qualitative study.

To identify the preferred design characteristics of smoking cessation services for school-age smokers, we conducted focus groups with teenage smokers motivated to stop smoking. We surveyed all pupils in years 9-11 (aged 13-16) in a random sample of 10 schools in Nottinghamshire, United Kingdom, to elicit details of smoking behavior, and conducted 25 focus groups in 6 schools with current smokers who wanted to stop smoking. Of 4,065 pupils surveyed, 888 (22%) were current smokers, and 438 (50% of smokers) wanted to quit smoking. We sampled 226 of these individuals for focus group studies, and 135 (60%) participated. These participants were motivated to quit, and almost all had tried to do so but had found it too difficult. Many were aware of smoking cessation methods but had low perceptions of their effectiveness based on their own or others' poor experiences of these interventions, and few were aware of the possibility of professional cessation support. Given clear, nondirective information about interventions, participants reported a preference for confidential, nonjudgmental services delivered during school time by a trained counselor, allowed the option to attend with friends, and offered nicotine replacement therapy (NRT). School-age smokers in Nottinghamshire, United Kingdom, who are motivated to stop smoking have low knowledge and opinions of smoking cessation interventions. Our findings indicate that young smokers would favor school-based services offering confidential professional counseling and NRT.     

Sociodemographic predictors of success in smoking intervention

AIM: To examine the role of sociodemographic factors as predictors of sustained smoking cessation for the population who volunteer to participate in intervention programmes. METHOD: Data for the 3575 smokers who participated in the CEASE (collaborative European anti-smoking evaluation) trial, a European multicentred study that used transdermal nicotine patches as an adjunct to smoking cessation in the chest clinic, were analysed. The effects of age, sex, smoking habit, socioeconomic status (housing conditions, education, and employment), disease, smoking habits of relatives, and baseline markers of tobacco use on sustained smoking cessation (self-reported abstinence and expired carbon monoxide < 10 parts per million) were assessed using logistic regression modelling (odds ratio (OR), 95% confidence interval (CI)). RESULTS: 477/3575 smokers were sustained abstainers one year after the intervention (overall success rate 13.3%). In the univariable logistic regression models an effect of active treatment on smoking cessation was observed (OR 1.50, 95% CI 1.15 to 1.96), and additional effects on outcome were found for age (OR 1.02, 95% CI 1.01 to 1.03), sex (men v women: OR 1.38, 95% CI 1.14 to 1.68), housing conditions (OR 1.43, 95% CI 1.25 to 1.65), current respiratory (OR 0.79, 95% CI 0.67 to 0.92) or cardiac disease (OR 0.46, 95% CI 0.28 to 0.75), and markers of tobacco use (cigarettes per day: OR 0.79, 95% CI 0.69 to 0.90; expired carbon monoxide: OR 0.98, 95% CI 0.97 to 0.99). Education and employment did not have a significant effect on the outcome. The effect of the variables associated with success in smoking cessation persisted after adjustment for covariates. CONCLUSION: Age, sex, and housing conditions have a major effect on smoking cessation in European smokers participating in smoking cessation programmes.     

Correlates of home smoking restrictions among rural smokers.

The prevalence of smoking is greater and smoking restrictions are less common in rural areas in comparison to urban areas. Consequently, rural smokers and their families are at increased risk for adverse health consequences from smoking. The presence of home smoking restrictions (i.e., limiting or banning cigarette smoking in the home) can be a mediator for smoking cessation and can reduce health risks for those who live with smokers. The purpose of the present study was to identify correlates of home smoking restrictions among rural smokers. We surveyed 472 smokers from 40 rural Kansas primary care practices who were enrolled in a smoking cessation intervention study. We assessed the prevalence of home smoking restrictions and examined the relationship between such restrictions, demographic variables, comorbid diagnoses, and psychosocial measures of smoking abstinence self-efficacy and motivation to quit. Complete home smoking restrictions were found among 25.4% of rural smokers with an additional 28.3% reporting some restrictions. Restrictions were associated with younger age, higher controlled motivation to quit (i.e., motivation from external pressure), the presence of children under age 6 years living in the home, fewer friends who smoke, and a partner who does not smoke. Smokers with a comorbid diagnosis of high cholesterol, chronic lung disease, or heart disease were less likely to have restrictions. Most smokers in rural primary care practices do not have home smoking restrictions, particularly those without children or a nonsmoking partner and those with significant risk factors for smoking-related illnesses. These patients may be critical targets for broaching issues of home smoking restrictions.     

Gabapentin for smoking cessation: a preliminary investigation of efficacy.

Gabapentin affects the glutamate and gamma amino butyric acid (GABA) neurotransmitters through which it may facilitate smoking abstinence. To obtain preliminary estimates of efficacy of gabapentin for smoking cessation, we conducted a single-arm, open-label study of gabapentin, 1,800-mg/day administered in three equal divided doses for 8 weeks. A total of 50 adult smokers were enrolled. All participants received a brief behavioral intervention at each medication visit. A total of 37 participants completed all follow-up assessments. At end-of-treatment the biochemically confirmed point-prevalence and prolonged smoking abstinence rates were 28% (95% CI=16%-42%) and 24% (95% CI=13%-38%), respectively. At 6 months, the biochemically confirmed point-prevalence and prolonged smoking abstinence rates were 20% (95% CI=10%-34%) and 16% (95% CI=7%-29%), respectively. Among subjects who continued to smoke and completed the follow-up assessments, the reported number of cigarettes smoked per day (mean+/-standard deviation) was significantly less than at baseline: -10.0+/-8.2 (p<.001). Adverse effects were minor and well tolerated. Our results suggest that gabapentin may increase smoking abstinence. An adequately powered randomized clinical trial assessing different doses of this drug against a placebo would be the reasonable next step.     

Smoking cessation patterns in methadone-maintained smokers.

To determine predictors of smoking cessation duration in a randomized clinical trial, we assigned participants to nicotine patch (8-12 weeks) plus either (a) a baseline tailored brief motivational intervention, a quit date behavioral skills counseling session, and a relapse prevention follow-up session, or (b) brief advice using the National Cancer Institute's 4A's model. A total of 383 smokers from five methadone maintenance treatment centers in Rhode Island were enrolled, of whom 312 (82%) completed 6-month follow-up assessments. The primary outcome was longest period of self-reported abstinence during follow-up. Participants were on average 40.5 years of age; 51.9% were male, and 77.6% were White. In multivariate analysis controlling for demographics, nicotine dependence, depressive symptoms, and smoking-related symptoms, we found longer periods of abstinence in persons reporting at least one 24-hr quit attempt in the year prior to baseline (OR = 1.97, p = .003), in those anticipating success in cessation (OR = 1.33, p = .024), and in those with a greater percentage of nicotine patch use days (OR = 2.78, p<.001). Past quit attempts, self-efficacy, and constant nicotine replacement were associated with duration of abstinence among methadone-maintained smokers. Attention to these domains in future intervention studies may improve treatment success.     

Proactive, motivationally enhanced smoking cessation counseling among women with elevated cervical cancer risk.

Current treatment guidelines recommend that all smokers be given motivational or action-oriented counseling, as is appropriate to their readiness to quit smoking. The present study assessed the acceptability and impact of a proactively delivered, motivationally tailored phone counseling program targeted to women with elevated risk for cervical cancer. Female smokers with a recent abnormal pap exam or a colposcopy were contacted and invited to participate, regardless of their interest in quitting smoking. Participants were randomly assigned to usual care (UC) or UC plus motivationally enhanced phone counseling (MEC). The intervention was well received: 79% of eligible women enrolled (n = 275), and 90% completed at least three of four calls. Participation did not vary by baseline motivation to quit. Compared with control subjects, counseling participants were more likely to seek additional treatment services and had a higher 7-day point-prevalence abstinence rate at 6 months (20% MEC vs. 12% UC, p<.05). MEC impact was sustained at 12 months, but abstinence increased among the UC group (18% MEC vs. 20% UC, p = ns). There was no difference in repeated point-prevalence abstinence at 6 and 12 months (11% MEC vs. 10% UC, p = ns). Outcomes were similar in a subgroup of 229 women who, at baseline, were interested in quitting in the next 6 months.
