Abstract
OBJECTIVES To evaluate the efficacy of intensive smoking cessation interventions (ISCIs) directly compared with shorter interventions (SIs), measured as successful quitting. METHOD Medline, Embase, the Cochrane Library and CINAHL were searched on 15 October 2021. Peer-reviewed randomised controlled trials (RCTs) of adult, daily smokers undergoing an ISCI were included. No setting, time or language restrictions were imposed. Risk of bias and quality of evidence was assessed using the Cochrane tool and Grading of Recommendations, Assessment, Development and Evaluation, respectively. Meta-analyses were conducted using a random-effects model. RESULTS 17 550 unique articles were identified and 17 RCTs evaluating 9812 smokers were included. 14 studies were conducted in Europe or the USA. The quality of the evidence was assessed as low or moderate. Continuous abstinence was significantly higher in ISCIs in the long term (risk ratio 2.60, 95% CI 1.71-3.97). Direction and magnitude were similar in the short term; however, they were not statistically significant (risk ratio 2.49, 95% CI: 0.94-6.56). When measured as point prevalence, successful quitting was still statistically significant in favour of ISCIs, but lower (long term: 1.64, 1.08-2.47; short term: 1.68, 1.10-2.56). Sensitivity analysis confirmed the robustness of the results. CONCLUSION ISCIs are highly effective compared to SIs. This important knowledge should be used to avoid additional morbidity and mortality caused by smoking.

Abstract
BACKGROUND Group therapy offers individuals the opportunity to learn behavioural techniques for smoking cessation, and to provide each other with mutual support. OBJECTIVES To determine the effect of group-delivered behavioural interventions in achieving long-term smoking cessation. SEARCH METHODS We searched the Cochrane Tobacco Addiction Group Specialized Register, using the terms 'behavior therapy', 'cognitive therapy', 'psychotherapy' or 'group therapy', in May 2016. SELECTION CRITERIA Randomized trials that compared group therapy with self-help, individual counselling, another intervention or no intervention (including usual care or a waiting-list control). We also considered trials that compared more than one group programme. We included those trials with a minimum of two group meetings, and follow-up of smoking status at least six months after the start of the programme. We excluded trials in which group therapy was provided to both active therapy and placebo arms of trials of pharmacotherapies, unless they had a factorial design. DATA COLLECTION AND ANALYSIS Two review authors extracted data in duplicate on the participants, the interventions provided to the groups and the controls, including programme length, intensity and main components, the outcome measures, method of randomization, and completeness of follow-up. The main outcome measure was abstinence from smoking after at least six months follow-up in participants smoking at baseline. We used the most rigorous definition of abstinence in each trial, and biochemically-validated rates where available. We analysed participants lost to follow-up as continuing smokers. We expressed effects as a risk ratio for cessation. Where possible, we performed meta-analysis using a fixed-effect (Mantel-Haenszel) model. We assessed the quality of evidence within each study and comparison, using the Cochrane 'Risk of bias' tool and GRADE criteria. MAIN RESULTS Sixty-six trials met our inclusion criteria for one or more of the comparisons in the review. Thirteen trials compared a group programme with a self-help programme; there was an increase in cessation with the use of a group programme (N = 4395, risk ratio (RR) 1.88, 95% confidence interval (CI) 1.52 to 2.33, I2 = 0%). We judged the GRADE quality of evidence to be moderate, downgraded due to there being few studies at low risk of bias. Fourteen trials compared a group programme with brief support from a health care provider. There was a small increase in cessation (N = 7286, RR 1.22, 95% CI 1.03 to 1.43, I2 = 59%). We judged the GRADE quality of evidence to be low, downgraded due to inconsistency in addition to risk of bias. There was also low quality evidence of benefit of a group programme compared to no-intervention controls, (9 trials, N = 1098, RR 2.60, 95% CI 1.80 to 3.76 I2 = 55%). We did not detect evidence that group therapy was more effective than a similar intensity of individual counselling (6 trials, N = 980, RR 0.99, 95% CI 0.76 to 1.28, I2 = 9%). Programmes which included components for increasing cognitive and behavioural skills were not shown to be more effective than same-length or shorter programmes without these components. AUTHORS' CONCLUSIONS Group therapy is better for helping people stop smoking than self-help, and other less intensive interventions. There is not enough evidence to evaluate whether groups are more effective, or cost-effective, than intensive individual counselling. There is not enough evidence to support the use of particular psychological components in a programme beyond the support and skills training normally included.

Abstract
BACKGROUND Tobacco smoking is known to be an important contributor to a wide variety of chronic diseases, especially in older adults. Information on health policy and practice, as well as evaluation of smoking cessation programs targeting older people, is almost nonexistent. PURPOSE To compare the real-world implementation of behavioral group therapy in relation to education alone for elderly smokers. MATERIALS AND METHODS Elderly smokers ready to quit smoking were identified from a cohort who completed a questionnaire at a smoking exhibition. They were allocated into two groups, behavioral therapy (3 days 9 hours) and education (2 hours), depending on their preferences. Demographic data, the Fagerstrom test for nicotine dependence (FTND) score, and exhaled carbon monoxide level were recorded at baseline. Smoking status of all subjects was followed at months 3, 6, and 12. Statistical differences in continuous abstinence rate (CAR) between the two groups were analyzed using chi-square tests. RESULTS Two hundred and twenty-four out of 372 smoking exhibition attendants met the enrollment criteria; 120 and 104 elected to be in behavioral group therapy and education-alone therapy, respectively. Demographic characteristics and smoking history were similar between both groups, including age, age of onset of smoking, years of smoking, smoking pack-years, education level, and nicotine dependence as measured by the FTND scale. The CAR of the behavioral therapy group at the end of the study (month 12) was significantly higher than the education group (40.1% vs 33.3%, P=0.034). Similar results were also found throughout all follow-up visits at month 3 (57.3% vs 27.0%, P<0.001) and month 6 (51.7% vs 25%, P<0.001). CONCLUSION Behavioral group therapy targeting elderly smokers could achieve higher short-and long-term CARs than education alone in real-world practice.

Abstract
Background The prevalence of cigarette smoking among adult gay males is higher than that of heterosexuals. There is a need for interventions adapted to gay culture. We conducted a pilot study using a modified version of a British smoking intervention programme tailored to gay men in Switzerland. As the main outcome, we assessed point prevalence smoking abstinence six months following programme attendance. Methods Seventy gay smokers attended seven weekly sessions in groups (median size = 5) taught by gay facilitators. A quit day was set in session 3. Integral components of the intervention were: discussing nicotine replacement therapy, performing carbon monoxide tests and forming ‘quit teams’. Seven-day point prevalence smoking abstinence, mental and physical health and the frequency of alcohol and drug use were assessed at baseline, in session 7 and at a six-month follow-up. Results Point prevalence abstinence significantly increased throughout the study (p = .00). At six months, 20 participants (28.6%) reported smoking abstinence over the previous 7 days. We observed increases in participants’ mental health between baseline and the six-month follow-up (p = .00). Participants who dropped out during the programme or were lost to follow-up smoked more cigarettes and were more nicotine dependent than the participants who were retained throughout the study duration (p ≤ .05). Conclusions This smoking cessation programme for gay men produced rates of point prevalence abstinence that were similar to interventions for non-gay groups. The programme presented an opportunity for gay men to quit smoking and interact with other gay non-smokers. Our results confirm the need to test this programme more systematically with a view toward implementing it on a larger scale in Switzerland. Trial registration Current Controlled Trials ISRCTN36851118 (02 October 2013).

Predictors of success in smoking cessation among Italian adults motivated to quit. J Subst Abuse Treat 2013; 44:534-40. [PMID: 23312770 DOI: 10.1016/j.jsat.2012.12.004] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2012] [Revised: 11/22/2012] [Accepted: 12/03/2012] [Indexed: 11/23/2022]
Abstract
We examined the role of sexual gender, age, working status, education, cigarettes per day, Fagerström test, age of onset, pharmacologic intervention (bupropion or varenicline), 10 sessions of cognitive-behavioral group counseling therapy (GCT) conducted over 6 weeks, and level of attendance of the counseling program as predictors of smoking cessation on 1282 Italian adult smokers. Results of a multi-variate forward stepwise conditional logistic analysis, at the first step, indicate that subjects who attended the program from 4 to 6 sessions and from 1 to 3 sessions, respectively, resulted about 3 times and 24 times more likely to smoke than those attending from 7 to 10 sessions; at the second step, subjects with high Fagerström score were 2 times more likely to smoke than subjects with low/middle Fagerström; at the third step, subjects treated only with GCT were 2 times more likely to smoke than subjects with combined pharmacologic interventions and GCT; at the fourth step, subjects with age of onset less than 17 years were 1.5 times more likely to smoke than subjects with a higher age of onset; eventually, at the fifth step women resulted 1.5 times more likely to smoke than men. In conclusion, we found that a steady attendance of the cognitive behavioral program, as well as the addition of pharmacologic interventions to counseling, remarkably increased the probability of the smoking cessation behavior to be determined. Nevertheless, FTQ was a valid measure in predicting the smoking cessation, and women revealed to be more likely to keep the smoking behavior, as well as subjects who declared an age of onset less than 17 years.

Abstract
BACKGROUND No systematic basis has yet been published for specifying competences needed to underpin behavioural support for smoking cessation. PURPOSE The purpose of this study was to develop and apply a system for identifying competences required for the delivery of individual and group-based behavioural support for smoking cessation. METHODS Sets of recommended competences for behavioural support were identified from a range of guidance documents. Where possible, these were compared with ones based on behaviour change techniques identified within behavioural support programmes found to be effective in randomised controlled trials (RCTs) and, for individual behavioural support, ones associated with higher success rates in the English Stop Smoking Services. RESULTS Ninety-four competences were identified (71 individual and 23 additional group competences), of which 59 were cited in at least two guidance documents (51 and 8, respectively). Fourteen of the individual competences and three of the group competences were supported by RCT evidence and, for individual competences, nine were supported by evidence from the services. CONCLUSIONS It is possible to identify competences recommended for behavioural support for smoking cessation and subsets supported by different types of evidence. This approach can form the basis for the development of assessment and training of stop smoking practitioners and is currently doing so in a national programme in England. With further research, the list of evidence-based competences is likely to be extended.

Abstract
In cluster-randomized trials, it is commonly assumed that the magnitude of the correlation among subjects within a cluster is constant across clusters. However, the correlation may in fact be heterogeneous and depend on cluster characteristics. Accurate modeling of the correlation has the potential to improve inference. We use second-order generalized estimating equations to model heterogeneous correlation in cluster-randomized trials. Using simulation studies we show that accurate modeling of heterogeneous correlation can improve inference when the correlation is high or varies by cluster size. We apply the methods to a cluster-randomized trial of an intervention to promote breast cancer screening.

Abstract
BACKGROUND AND OBJECTIVE The aim of this study is to quantify the efficiency of the cognitive-behavioural treatment for smoking cessation in pregnancy and to evaluate the risk factors of success or failure for the abstinence before the childbirth. PATIENTS AND METHOD We studied 74 pregnant smoking women who, between January 2003 and January 2004, came to their obstetric regular control in the Hospital Casa Maternitat-Hospital Clínic i Provincial de Barcelona, and who voluntarily acceded to the cognitive-behavioural treatment without replacement of nicotine for the smoking cessation that they were offered. RESULTS 44% of women who made the program of visits came abstinent to the childbirth, and of them, 93.1% was abstinent during the quarantine. 51.5% reduced the consumption and 4.5% didn't change or increased the consumption. The fact that someone smokes at home (p = 0.006), the degree of dependence to the nicotine (p = 0.015) and a consumption of coffee superior to 3 daily cups (p = 0.039), in an equation of logistic regression, classified both groups (abstinence/not abstinence). CONCLUSIONS The efficiency of a program based on cognitive-behavioural therapy, without replacement of nicotine, for the smoking cessation in the pregnancy is confirmed in our sample. We propose to consider risk factors of treatment failure the fact that someone smokes at home and a daily high consumption of coffee.

Abstract
BACKGROUND Group therapy offers individuals the opportunity to learn behavioural techniques for smoking cessation, and to provide each other with mutual support. OBJECTIVES We aimed to determine the effects of smoking cessation programmes delivered in a group format compared to self-help materials, or to no intervention; to compare the effectiveness of group therapy and individual counselling; and to determine the effect of adding group therapy to advice from a health professional or to nicotine replacement. We also aimed to determine whether specific components increased the effectiveness of group therapy. We aimed to determine the rate at which offers of group therapy are taken up. SEARCH STRATEGY We searched the Cochrane Tobacco Addiction Group Trials Register, with additional searches of MEDLINE and PsycINFO, including the terms behavior therapy, cognitive therapy, psychotherapy or group therapy, in January 2005. SELECTION CRITERIA We considered randomized trials that compared group therapy with self help, individual counselling, another intervention or no intervention (including usual care or a waiting list control). We also considered trials that compared more than one group programme. We included those trials with a minimum of two group meetings, and follow up of smoking status at least six months after the start of the programme. We excluded trials in which group therapy was provided to both active therapy and placebo arms of trials of pharmacotherapies, unless they had a factorial design. DATA COLLECTION AND ANALYSIS We extracted data in duplicate on the participants, the interventions provided to the groups and the controls, including programme length, intensity and main components, the outcome measures, method of randomization, and completeness of follow up. The main outcome measure was abstinence from smoking after at least six months follow up in patients smoking at baseline. We used the most rigorous definition of abstinence in each trial, and biochemically validated rates where available. Subjects lost to follow up were analyzed as continuing smokers. Where possible, we performed meta-analysis using a fixed-effects (Mantel-Haenszel) model. MAIN RESULTS A total of 55 trials met inclusion criteria for one or more of the comparisons in the review. Sixteen studies compared a group programme with a self-help programme. There was an increase in cessation with the use of a group programme (N = 4395, odds ratio (OR) 2.04, 95% confidence interval (CI) 1.60 to 2.60). Group programmes were more effective than no intervention controls (seven trials, N = 815, OR 2.17, 95% CI 1.37 to 3.45). There was no evidence that group therapy was more effective than a similar intensity of individual counselling. There was limited evidence that the addition of group therapy to other forms of treatment, such as advice from a health professional or nicotine replacement, produced extra benefit. There was variation in the extent to which those offered group therapy accepted the treatment. There was limited evidence that programmes which included components for increasing cognitive and behavioural skills and avoiding relapse were more effective than same length or shorter programmes without these components. This analysis was sensitive to the way in which one study with multiple conditions was included. We did not find an effect of manipulating the social interactions between participants in a group programme on outcome. AUTHORS' CONCLUSIONS Group therapy is better for helping people stop smoking than self help, and other less intensive interventions. There is not enough evidence to evaluate whether groups are more effective, or cost-effective, than intensive individual counselling. There is not enough evidence to support the use of particular psychological components in a programme beyond the support and skills training normally included.
