Although a considerable body of evidence supports telephone quit lines for smoking cessation, much less is known about the effectiveness of proactive Telephone Counseling with smokeless tobacco (ST) users. We conducted a randomized controlled trial comparing Telephone Counseling with the distribution of a self-help manual for ST cessation. We recruited 406 adult ST users throughout the state of Minnesota and randomized them to receive either: (a) a self-help manual (Manual only) or (b) a self-help manual plus proactive telephone-based cessation counseling (Telephone Counseling). The telephone-based treatment included up to four calls in support of quitting, and personalized various cognitive and behavioral strategies that are generally considered effective in tobacco cessation (such as setting a quit date, examining patterns of use, developing stress reduction skills, avoiding known triggers to use). Participants were surveyed by phone at 3 and 6 months to assess both point prevalence and continued abstinence. Prolonged abstinence from all tobacco was 6.8% and 30.9% (p < .001) at 3 months and 9.8% and 30.9% (p < .001) at 6 months in Manual only and Telephone Counseling, respectively. We found older age, lower dependency, and increased readiness predicted quitting success. Proactive telephone-based counseling is an effective strategy for improving cessation rates among ST users. Future research should determine the components contributing to the intervention success. Smokeless tobacco (ST) is associated with adverse health consequences yet treatment resources for ST are not widely available. Cost-effective behavioral interventions incorporating self-help materials and counseling calls have been demonstrated to reduce ST use rates and can be easily disseminated, but the feasibility and effectiveness of incorporating pharmacotherapy into this approach have not been evaluated. We conducted a clinical pilot study randomizing 60 patients to 12 weeks of the 4-mg nicotine lozenge or placebo delivered through the mail. All subjects received an assisted self-help intervention (ASH) with telephone support. At the end of the medication phase, lozenges were being used by 63% of subjects in the 4-mg nicotine lozenge group and 43% in placebo. The nicotine lozenge decreased composite withdrawal symptoms and adverse events were minimal. No significant differences were observed in abstinence rates between the two groups at 3 or 6 months. We conclude that the mailing of nicotine lozenges to ST users is a feasible and safe strategy the efficacy of which needs to be evaluated.

The need for effective, low-cost self-help treatment methods for smokeless tobacco (ST) addiction becomes more evident as rates of product use and associated morbidities increase. This study evaluated two self-help methods for ST cessation. One hundred ninety-eight ST users were randomized into two conditions: half received the LifeSign, a credit card-sized computer designed for gradual ST cessation, and half received the Enough Snuff self-help manual and a video. Subjects in both conditions received telephone support for their quit effort. The study was conducted entirely through phone and mail, allowing delivery of the intervention to both rural and urban users. Self-reported rates of sustained abstinence (no tobacco use at two months and six months) were 24.5% for the manual/video condition, and 18.4%, for the LifeSign condition. Smokers (N = 3,030) were randomized to receive 1 of 3 interventions: (a) a self-help quit kit, (b) a quit kit plus 1 telephone counseling session, or (c) a quit kit plus up to 6 telephone counseling sessions, scheduled according to relapse probability. Both counseling groups achieved significantly higher abstinence rates than the self-help group. The rates for having quit for at least 12 months by intention to treat were 5.4% for self-help, 7.5% for single counseling, and 9.9% for multiple counseling. The 12-month continuous abstinence rates for those who made a quit attempt were 14.7% for self-help, 19.8% for single counseling, and 26.7% for multiple counseling. A dose-response relation was observed, as multiple sessions produced significantly higher abstinence rates than a single session. The first week after quitting seems to be the critical period for intervention. Military personnel are twice as likely as civilians to use smokeless tobacco (ST). This study evaluated the efficacy of a minimal-contact ST cessation program in military personnel.
                Participants were recruited from 24 military dental clinics across the United States during annual dental examinations. Participants were 785 active-duty military personnel who were randomly assigned to receive a minimal-contact behavioral treatment (n = 392) or usual care (n = 393). The behavioral treatment included an ST cessation manual, a videotape cessation guide tailored for military personnel, and three 15-min telephone counseling sessions using motivational interviewing methods. Usual care consisted of standard procedures that are part of the annual dental examination, including recommendations to quit using ST and referral to extant local tobacco cessation programs. Participants were assessed at 3 and 6 months after enrollment.
                Participants in the ST cessation program were significantly more likely to be abstinent from all tobacco, as assessed by repeated point prevalence at both 3 and 6 months (25.0%), and were significantly more likely to be abstinent from ST use for 6 months, as assessed by prolonged abstinence (16.8%), compared with participants in usual care (7.6% and 6.4%, respectively).
                These results indicate that a minimal-contact behavioral treatment can significantly reduce ST use in military personnel and has the potential for widespread dissemination. If ST users were identified in dental visits and routinely referred to telephone counseling, this could have a substantial benefit for the health and well-being of military personnel. GPs often lack time to provide intensive cessation advice for patients who smoke. This study aimed to determine the effectiveness of opportunistic referral of smokers by their GP for telephone cessation counselling by a trained nurse.
                Adult smokers (n = 318) attending 30 GPs in South Western Sydney, Australia were randomly allocated to usual care or referral to a telephone-based program comprising assessment and stage-based behavioural advice, written information and follow-up delivered by a nurse. Self-reported point prevalence abstinence at six and 12 months was compared between groups. Characteristics of patients who accepted and completed the intervention were investigated.
                Of 169 smokers randomised to the intervention, 76 (45%) consented to referral. Compared with smokers in 'pre-contemplation', those further along the stage-of-change continuum were significantly more likely to consent (p = 0.003). Those further along the continuum also were significantly more likely to complete all four calls of the intervention (OR 2.6, 95% CI: 0.8-8.1 and OR 8.6, 95% CI: 1.7-44.4 for 'contemplation' and 'preparation' respectively). At six months, there was no significant difference between groups in point prevalence abstinence (intention to treat) (9% versus 8%, p = 0.7). There was no evidence of differential intervention effectiveness by baseline stage-of-change (p = 0.6) or patient sex (p = 0.5). At 12 months, point prevalence abstinence in the intervention and control groups was 8% and 6% respectively (p = 0.6).
                Acceptance of opportunistic referral for nurse delivered telephone cessation advice was low. This trial did not demonstrate improved quit rates following the intervention. Future research efforts might better focus support for those patients who are motivated to quit. AUSTRALIAN CLINICAL TRIALS REGISTRY NUMBER: ACTRN012607000091404. Self-help materials computer-tailored to the specific needs of smokers have shown promise as a high-reach, low-cost intervention for smoking cessation. Adding tailored cessation materials to telephone-based cessation counseling may be a way of generating greater efficacy in promoting and maintaining cessation. The objective of this study is to assess the efficacy of adding different types of behavioral smoking cessation materials to brief telephone-based cessation counseling.A total of 1,978 smokers calling the National Cancer Institute's (NCI's) Cancer Information Service (CIS) for help in quitting smoking initially received brief cognitive-behavioral cessation counseling from a CIS information specialist. Following a baseline interview administered by the information specialist, subjects were randomly assigned to one of four conditions, each delivered by U.S. mail: a single, untailored smoking cessation guide (SU); a single, tailored smoking cessation guide (ST); a series of four (multiple) printed materials tailored only to baseline data (MT); and a series of four (multiple) printed materials tailored to baseline as well as retailored using 5-month interim progress data (MRT). The primary outcome measure was 7-day point prevalence abstinence rates assessed using a computer-assisted telephone interview (CATI) at 12-month follow-up.At 12-month follow-up, using intent-to-treat, imputed, and per-protocol analyses, no differences were found among the four experimental conditions (linear trend), or when the ST, MT, and MRT groups were compared with the control (SU) group. Participants in the two multiple message group conditions combined (MT + MRT), however, had significantly higher abstinence rates than participants in the two single message group conditions combined (SU + ST). Moreover, among subjects who reported quitting at the 5-month follow-up, participants receiving the MRT materials reported higher abstinence rates at 12 months than the other three groups combined (SU + ST + MT). The results of this study support the effectiveness, over and above a single telecounseling interaction, of multiple tailored print material contacts on cessation. These effects, however may be due to tailoring, or the longitudinal nature of the two multiple tailored conditions, or both. The strongest evidence for tailoring occurred in the MRT condition for relapse prevention, suggesting that print materials tailored to interim progress may be especially effective in this context. The qualities of specific psychosocial and communication elements in tailored materials should receive attention in future research. To examine whether telephone counselling based on the stages of change component of Transtheoretical model of behaviour change together with educational materials could help non-motivated smoking parents of young children to cease.
                Randomised controlled trial.
                Hong Kong Special Administrative Region, PR China.
                952 smoker fathers and mothers of Chinese children aged 5 years.
                Participants were randomly allocated into two groups: the intervention group received printed self-help materials and three-session telephone-based smoking cessation counselling delivered by trained counsellors; the control group received printed self-help materials only. A structured questionnaire was used for data collection at baseline and at 1, 3 and 6 month follow up.
                The main outcome is 7 day point prevalence quit rate at 6 months (defined as not smoking during the 7 days preceding the 6 month follow up) determined by self reports. Other secondary outcomes were self reported 24 h point prevalence quit rate and self-reported continuous quit rate and bio-chemically validated quit rate at 6 months.
                A total of 952 smoker fathers and mothers were randomized to the intervention (n = 467) and control (n = 485) groups. Most were daily smokers (92.4%) and the mean number of cigarettes smoked per day was 14.5 (SD = 8.9). By using intention-to-treat analysis, the 7 day point prevalence quit rate at 6 month follow up was significantly greater in the intervention group (15.3%; 68/444) than the control group (7.4%; 34/459) (P < 0.001). The absolute risk reduction was 7.9% (95% confidence interval: 3.78% to 12.01%). The number needed to treat to get one additional smoker to quit was 13 (95% CI: 8-26). The crude odds ratio of quitting was 2.3(95% CI: 1.5-3.5). The adjusted odds ratio was 2.1 (95% CI: 1.4-3.4) (adjusted for age, number of years smoked, and alcohol dependency).
                Proactive telephone counselling is an effective aid to promote smoking cessation among parents of young children. Cancer survivors smoke at rates that are only slightly lower than the general population. This article reports on the final outcomes of Partnership for Health, a smoking cessation intervention for smokers in the Childhood Cancer Survivors Study (CCSS).
                This study is a randomized control trial with follow-up at 8 and 12 months that involved smokers (n = 796) enrolled onto the CCSS cohort. Participants were randomly assigned to either a self-help or a peer-counseling program that included up to six telephone calls from a trained childhood cancer survivor, tailored and targeted materials, and free nicotine replacement therapy. The intervention was delivered by telephone and postal service mail.
                The quit rate was significantly higher in the counseling group compared with the self-help group at both the 8-month (16.8% v 8.5%; P < .01) and 12-month follow-ups (15% v 9%; P < or = .01). Controlling for baseline self-efficacy and readiness to change, the intervention group was twice as likely to quit smoking, compared with the self-help group. Smoking cessation rate increased with an increase in the number of counseling calls. The cost of delivering the intervention was approximately 300 dollars per participant. The incremental cost-effectiveness of the intervention compared with controls was 5,371 dollars per additional quit.
                Interventions to prevent future illnesses are of critical importance to childhood cancer survivors. The Partnership for Health intervention resulted in a doubling of smoking cessation quit rates. Because of the seriousness of smoking among childhood cancer survivors, this intervention model may be appropriate as a multicomponent treatment program for survivors who smoke. The present study used telephone support both to sustain abstinence and to encourage renewed quit attempts in smokers who had completed an intensive smoking cessation clinic.
                Subjects were hard-core smokers (n = 1083) who had attended a multisession cessation clinic. They were then assigned randomly to receive telephone support (intervention calls 3, 9, and 21 months after the targeted cessation clinic quit date) or no further intervention.
                In the intervention condition, subjects who relapsed were significantly more likely to resume abstinence (that is, to recycle) than those in the comparison condition at follow-up (6 months: 17.8% vs 11.3%; 24 months: 25.7% vs 18.2%). Telephone support was not effective in preventing relapse, and overall differences in abstinence outcome were not significant.
                The major hypothesis of the current study--that telephone support would enhance the resumption of abstinence--received partial support. However, there was no evidence either of an overall treatment effect or of an effect in preventing relapse. Telephone outreach may be more effective in the context of self-help or other less intensive interventions. The authors evaluated the incremental efficacy of telephone counselling by a nurse in addition to physician advice and nicotine replacement therapy in helping patients to stop smoking.
                The trial was conducted at the University of Ottawa Heart Institute. A total of 396 volunteers who smoked 15 or more cigarettes daily were randomly assigned to either of 2 groups: usual care (control group) and usual care plus telephone counselling (intervention group); the groups were stratified by sex and degree of nicotine dependence. Usual care involved the receipt of physician advice on 3 occasions, self-help materials and 12 weeks of nicotine replacement therapy. Telephone counselling was provided by a nurse at 2, 6 and 13 weeks after the target quit date. Point-prevalent quit rates were determined at 52 weeks after the target quit date.
                The point-prevalent quit rates at 52 weeks did not differ significantly between the control and intervention groups (24.1% v. 23.4% respectively). The quit rates did not differ significantly at the secondary measurement points of 4, 12 and 26 weeks.
                Brief physician assistance, along with nicotine replacement therapy, can help well-motivated smokers to quit. Three additional sessions of telephone counselling by a nurse were ineffective in increasing quit rates. This form of assistance may be useful in the absence of physician advice or when self-selected by patients. Nonsmokers have a potentially supportive role in tobacco cessation efforts. The present study examined the feasibility, acceptability, and potential efficacy of a telephone-based intervention for nonsmoking support persons.
                A total of 59 support persons (mean age = 36 years, 92% female, 95% White) were randomly assigned to a control condition (N = 30; written materials only) or to a social cognitive theory-based intervention (N = 29; written materials and 5 weekly, 20- to 30-min telephone counseling sessions). Both support persons and smokers completed assessments separately by mail at baseline and at weeks 6 (end of treatment) and 26.
                Two thirds of the smokers reported low-moderate levels of motivation to quit at baseline as assessed by the contemplation ladder. Study retention rates were excellent, with 95% of both support persons and smokers completing the week 26 assessment. Moreover, 86% of support persons in the intervention group completed all five telephone sessions. Treatment acceptability was high for both support persons and smokers. Compared with the control condition, the intervention was associated with a significant increase in support person self-efficacy to help their smoker (p = .034) and outcome expectancies (p = .025) from baseline to week 6. However, the intervention was not associated with higher smoking abstinence rates or quit attempts.
                The program was successful in reaching smokers with lower levels of readiness to quit. The intervention was feasible and acceptable to both support persons and smokers. Although support persons and smokers can be engaged in this type of outreach program, refinements in the intervention approach are needed to improve the smoking outcomes. To evaluate the effectiveness of the Five-Day Plan (FDP) in helping smokers to stop smoking.
                Randomized controlled trial comparing intervention and control groups. The primary outcome measure was 12 months continuous abstinence verified by expired air carbon monoxide concentration. Secondary outcome measures were self-reported abstinence at end of treatment, at 3 and 6 months.
                Six towns in France.
                228 smokers, recruited by newspaper and radio advertisement, aged 18 years or over and willing to make an attempt to quit smoking.
                The Intervention group (119 participants) received the FDP, which is a behavioural group-based treatment programme that has been in operation in France since 1965. It involves five consecutive evening behavioural therapy sessions. The Control group (109 participants) received a single session discussing the health effects of smoking.
                In the Intervention group, 67 participants (56%) quit smoking at the end of the FDP. After three months this number had been reduced to 30 (25%) and to 19 (16%) by the end of one year. In the Control group these numbers were 14 (13%) and 12 (11%), respectively, after three and 12 months. When considering the rate of cessation without lapse after one year a significant difference was observed with a 13% rate in the Intervention group and 3% in the Control group (P = 0.004).
                The FDP may be considered as an aid for smokers who want to quit. There is new evidence that smokers of all ages benefit from cessation of smoking. Although most older smokers, like younger smokers, prefer to quit on their own, at the time this project was started, there were no materials or programs targeted to older smokers. Using the literature, focus groups with older smokers and a national survey of older smokers, we created Clear Horizons, a self-help guide for older smokers, and a telephone counseling protocol tailored to the needs of older smokers (age 50-74). Smokers were recruited from around the United States and assigned randomly to a control guide, Clearing the Air, Clear Horizons alone or Clear Horizons and two counselor calls. Follow-up of nearly 2000 smokers was conducted by telephone 3, 6, 12 and 24 months after delivery of the self-help guides. This report focuses primarily on results at 3 months because that was the measurement for reactions to the interventions. At the 3 month interview, those in the tailored interventions rated their guides more highly than did those in the control group. They also read more of their guides and were more likely to reread them. Quit rates were significantly higher among smokers who received a combination of the tailored guide and telephone counseling. At 3 months, the combination of the guide and telephone counseling was most effective in helping smokers to quit. By 12 months, both the tailored guide alone and the tailored guide and calls groups had higher quit rates than the control guide but were not statistically different from one another. The development of acceptable, widely available and effective smoking cessation methods is central to public health strategy for tobacco control. We examined the effectiveness of a telephone callback counselling intervention, compared to the provision of self-help resources alone.
                Participants were 998 smokers calling a state-wide "Quitline" service randomly allocated to either callback counselling or ordinary care. The callback condition consisted of a series of brief counselling calls at strategic times in addition to ordinary care. The number of calls varied according to caller needs, and most occurred generally just before the person's quit day and in the week or two after it. The service was delivered by trained telephone counsellors.
                At the 3-month follow-up, significantly more participants in the callback group (24%) reported that they were quit, compared to those in the usual care comparison group (13%). The difference in point prevalence of smoking declined to 6% by the 12-month follow-up. Using sustained abstinence there was a significant benefit of callback counselling at 12-month follow-up. Treating dropouts as smokers reduced the overall magnitude of the effects somewhat. The benefit of callbacks was to marginally increase quit attempts and to significantly reduce relapse.
                Our findings are consistent with those of other studies demonstrating benefits of callback telephone counselling to facilitate cessation. Such counselling provides a flexible, relatively inexpensive and widely available form of cessation service. It appears to encourage a greater proportion of quit attempts and to reduce the rate of relapse among those quitting. Further research is required to determine ways to enhance effectiveness, particularly studies of how to reduce relapse. Until 1990, smoking cessation interventions in the Netherlands were limited. The utility and effectiveness of community-based smoking cessation programs have not been examined.
                In a treatment city (Den Bosch) a multicomponent community-based smoking cessation intervention was implemented in which local mass media and general practitioners draw smokers' attention to a local quit line. Telephone counselors advised applicants on their choice between self-help and group treatment and optional telephone counseling. Another Dutch city (Apeldoorn) served as a control. Population samples of smokers (n = 547 and n = 546) were interviewed three times at approximately 7-month intervals. Self-help manual requesters (n = 84) and group participants (n = 83) were interviewed before and 6 months after treatment.
                Treatment modalities were successful; 13% of self-help manual requesters and 22% of group participants were abstinent after 6 months. On a population level the intervention resulted in significantly higher recall of self-help manual and group program in the treatment city. A modest intervention effect on prevalence of abstinence was found at the community level.
                Treatment modalities were effective within their participants, but the intervention effectiveness on a community level was limited. No significant difference was found between quit rates after 14 months (7% in treatment city and 9% in control city). Several system failures could be identified. However, probably the intervention effect was seriously confounded by two national governmental publicity campaigns introducing and reinforcing a mandatory smoking ban and a series of national campaigns initiated by the united Dutch tobacco producers opposing the ban. To evaluate the relative effectiveness of two self-help smoking interventions as adjuncts to a self-help manual and telephone support service (hotline) for older smokers.
                Subjects were stratified on baseline variables and randomised to one of two treatment conditions in a methods development study.
                177 community-dwelling smokers aged 60 years and older.
                All subjects received a self-help manual and access to a smokers' telephone hotline. Subjects also received either mailings (Letters condition) or counselling telephone calls (Proactive condition) at four and eight weeks after enrollment.
                Use of the hotline and prevalence of abstinence lasting at least 48 hours (verified by a "significant other") were assessed at three and six months for the full sample. Seven-day abstinence was calculated for comparison with previous research. A subsample of 91 subjects was followed up at 12 months.
                Overall abstinence rates for the two conditions were in the range of typical self-help interventions. Men were more likely to be abstinent than women at follow up at three and six months. A significant gender x treatment interaction was found, with abstinence rates higher for men in the Letters condition, and women in the Proactive condition. Hotline use was high, with nearly half of subjects calling by 12 months.
                Both interventions appear promising for older smokers, but may be differentially effective for men and women. Older smokers will use a hotline; whether Letters and Proactive interventions can improve on manual and hotline effectiveness rates alone is being tested in a subsequent controlled trial. Smoking remains the primary preventable cause of death and illness in the U.S. Effective, convenient treatment programs are needed to reduce smoking prevalence.
                This study compared the effectiveness of three modalities of a behavioral smoking-cessation program in smokers using varenicline.
                Current treatment-seeking smokers (n=1202) were recruited from a large healthcare organization between October 2006 and October 2007. Eligible participants were randomized to one of three smoking-cessation interventions: web-based counseling (n=401); proactive telephone-based counseling (PTC; n=402); or combined PTC and web counseling (n=399). All participants received a standard 12-week FDA-approved course of varenicline. Self-report determined the primary outcomes (7-day point prevalent abstinence at 3- and 6-month follow-ups); the number of days varenicline was taken; and treatment-related symptoms. Behavioral measures determined utilization of both the web- and Phone-based counseling.
                Intent-to-treat analyses revealed relatively high percentages of abstinence at 3 months (38.9%, 48.5%, 43.4%) and at 6 months (30.7%, 34.3%, 33.8%) for the web, PTC, and PTC-web groups, respectively. The PTC group had a significantly higher percentage of abstinence than the web group at 3 months (OR=1.48, 95% CI=1.12, 1.96), but no between-group differences in abstinence outcomes were seen at 6 months.
                Phone counseling had greater treatment advantage for early cessation and appeared to increase medication adherence, but the absence of differences at 6 months suggests that any of the interventions hold promise when used in conjunction with varenicline.

                Randomized controlled trial.
                The UK Quitline.
                A total of 1508 current smokers and recent ex-smokers.
                The control group received usual care (telephone counselling and an information pack sent through the post). The intervention group received in addition a computer-generated individually tailored advice letter.
                All outcomes were assessed at 6-month follow-up. The primary outcome measure was self-reported prolonged abstinence for at least 3 months. Secondary outcomes were self-reported prolonged abstinence for at least 1 month and 7-day and 24-hour point-prevalence abstinence.
                For the sample as a whole, quit rates did not differ significantly between the two conditions. However, among the majority (n = 1164) who were smokers at baseline, quit rates were consistently higher in the intervention group: prolonged abstinence for 3 months, 12.2% versus 9.0% [odds ratio (OR) = 1.40, 95% confidence interval (CI) = 0.96-2.04, P = 0.080); prolonged abstinence for 1 month, 16.4% versus 11.3% (OR = 1.53, 95% CI = 1.09-2.15, P = 0.013); 7-day point-prevalence abstinence, 18.9% versus 12.7% (OR = 1.59, 95% CI = 1.15-2.19, P = 0.004); 24-hour point-prevalence abstinence, 20.9% versus 15.4% (OR = 1.45, 95% CI = 1.07-1.96, P = 0.015).
                The results for the smokers are encouraging in showing a small but useful effect of the tailored letter on quit rate. Versions of the tailoring program could be used on the web and in general practices, pharmacies and primary care trusts. Predictors of smoking behavior change were examined in a randomized controlled trial of individualized smoking cessation counseling delivered by a smoking cessation counselor during periodic health examination. Self-reports of not smoking at 6 and 18 months and attempts to quit were greater, but not significantly so, in the intervention group compared with the usual care group. There was no difference between the intervention group and the usual care group in reported continuous abstinence. Multivariate analysis showed that longer periods of abstinence in the past and having smoking identified as the main problem were important predictors of subsequent quitting. Having fewer other smokers in the household, stronger intentions to stop smoking in the next month, and being in the intervention group were also significant predictors of abstinence at 6 months, but not at 18 months. Those who had tried to quit by 6 months and 18 months were more likely to be in the intervention group, to have greater motivation to stop smoking, and to have more problems of daily living. Supplementing physician's advice with individualized smoking cessation counseling during health maintenance examinations was associated with a greater short-term quit rate and more quit attempts over 18 months than physician advice alone, but did not influence continuous abstinence from cigarettes over this time. The effectiveness of low-cost smoking interventions targeted to pregnant women has been demonstrated, although few gains in absolute cessation rates have been reported in the past decade. Under conditions of typical clinical practice, this study examined whether outcomes achieved with brief counseling from prenatal care providers and a self-help booklet could be improved by adding more resource-intensive cognitive-behavioral programs.
                Randomized Clinical Trial.
                A large-group-model managed care organization.
                390 English-speaking women 18 years of age or older who self-reported to be active smokers at their initial prenatal appointment.
                Participants were randomized to one of three groups: (1) a self-help booklet tailored to smoking patterns, stage of change, and lifestyle of pregnant smokers; (2) the booklet plus access to a computerized telephone cessation program based on interactive voice response technology; or (3) the booklet plus proactive telephone counseling from nurse educators using motivational interviewing techniques and strategies. No attempt was made to change smoking-related usual care advice from prenatal providers.
                Biochemically confirmed abstinence measured by level of cotinine in urine samples obtained during a routine prenatal visit at approximately the 34th week of pregnancy.
                Twenty percent of participants were confirmed as abstinent with no significant differences found between intervention groups. Multivariate baseline predictors of cessation included number of cigarettes smoked per day, confidence in ability to quit, exposure to passive smoke, and educational level. No differential intervention effects were found within strata of these predictors or by baseline stage of readiness to change. Cessation rates among heavier smokers were strikingly low in all intervention groups.
                Neither a computerized telephone cessation program nor systematic provision of motivational counseling improved cessation rates over a tailored self-help booklet delivered within the context of brief advice from prenatal providers. Innovative strategies need to be developed to increase the effectiveness of existing prenatal smoking interventions. Special attention should be paid to the needs of heavier smokers. A partner's provision of support and smoking status has been consistently associated with women's likelihood of smoking cessation during pregnancy and relapse in postpartum.
                A three-group randomized controlled intervention trial was conducted in 1996 to 2001, with 583 women and their partners randomized to usual care (UC), woman-only (WO), or partner-assisted (PA) intervention. Follow-ups occurred at 28 weeks of pregnancy, and 2-, 6-, and 12-months postpartum.
                Womack Army Medical Center (WAMC) at Fort Bragg in Fayetteville, North Carolina.
                Women in the UC condition received provider advice to quit and a self-help guide. The WO condition received UC components plus a late-pregnancy relapse prevention kit (booklet and gift items) and six counseling calls (three in pregnancy and three postpartum) initiated by a health advisor. Women in the PA condition received the WO intervention, and their partners received telephone counseling and a support guide emphasizing skills to help the woman build and maintain her confidence to quit smoking. Partners who smoked also received cessation aids and related counseling.
                Seven-day self-reported abstinence from smoking at each follow-up.
                Intent-to-treat analyses showed no significant differences by condition in women's reports of abstinence at any follow-up. In late pregnancy, more partners were abstinent in the PA condition (15%) than in the UC condition (5%), p =0.02.
                Partner-assisted smoking-cessation interventions need further refinement. Influencing young couples' support patterns may require more intensive and conjoint intervention. Partners who smoke could benefit from support for their cessation efforts.
Varenicline and behavioural interventions may help ST users to quit. Behavioural interventions incorporating telephone counselling or an oral examination are likely to increase abstinence rates.
