Impact of a Brief Motivational Smoking Cessation Intervention

BACKGROUND-Few studies have rigorously evaluated whether providing biologically-based health risk feedback increases smokers' motivation to quit and long-term abstinence above standard interventions.

Predictors of past quit attempts and duration of abstinence among cigarette smokers

Journal of Epidemiology and Global Health, 2017

Objective: Despite the widespread awareness of the harms of smoking, millions continue to smoke around the world partly due to the difficulty it takes to quit smoking. Identifying the factors associated with making quit attempts is an essential pillar to reach successful quitting. The purpose of this study is to assess the factors associated with the past quit attempts and their past length of abstinence in a Lebanese sample of cigarette smokers. Methods: This study was conducted between March 2014 and March 2015, involving 382 patients randomly chosen from 5 outpatient clinics in 5 hospitals in Lebanon. A standardized questionnaire was completed including socio-demographic characteristics, smoking behavior, chronic respiratory symptoms, Fagerstrom scale, Mondor scale, packaging perception, quitting behavior and readiness to quit ladder. Results: Smokers who have chronic allergies (ORa = 2.45, p = 0.03), those who have ever stopped smoking for at least one month due to the warnings implemented on the packages (ORa = 4.6, p < 0.0001) and smokers with an intention to quit in 2 months (ORa = 2.49, p < 0.0001) had significantly more past quit attempts. Results: Furthermore, longer quit attempts duration (more than 1 month) were significantly associated with low-nicotine dependent smokers (ORa = 0.56, p = 0.02), higher-motivated smokers (ORa = 1.85, p = 0.01), people with chronic allergies (ORa = 2.07, p = 0.02), smokers who have ever stopped smoking for at least one month due to the warnings (ORa = 3.72, p < 0.0001) and those with an intention to quit in 2 months (ORa = 1.98, p = 0.05). Conclusion: The promoters of smoking cessation services should consider these factors when designing comprehensive tobacco control initiatives and in service planning.

Smoking Cessation : Treatment Intensity and Outcome in Randomized Clinical Trials

2013

The primary aim was to compare the effectiveness of smoking cessation interventions of different intensities in a clinical dental and a telephone setting in Sweden. Methods: A total of 300 smokers were randomized to High or Low Intensity Treatment (HIT or LIT) at the Public Dental Service, County Council of Västmanland. Effectiveness (abstinence rate) was measured after 1yr (paper I) and 5-8yrs (paper III). A cost-effectiveness analysis was conducted, based on intervention costs, number of abstinent participants after 1yr, and a Markov modelling of future costs and health (in QALYs) consequences (paper II). In paper IV, 586 callers to the Swedish National Tobacco Quitline (SNTQ) were randomized to highintensity proactive or low-intensity reactive service, and effectiveness was measured after 1 yr. Effectiveness measures were self-reported point prevalence, 6-month continuous abstinence, and sustained abstinence. Results: Absolute quit rates were 7% higher with HIT than with LIT on all measures and increased by 8% from 1yr to 5-8yrs. Point prevalence was 23% vs. 16% (p=.11) after 1yr and 31% vs. 24% (p=.16) after 5-8yrs. Six-month continuous abstinence was 18% vs. 9% (p =.02) after 1yr and 26% vs.19% (p=.18) after 5-8yrs. Sustained abstinence was 12% vs. 5% (p =.03) after 5-8yrs. Nicotine dependence was a strong predictor for abstinence at 1yr and achieved abstinence at 1yr was a strong predictor for abstinence at long-term follow-up. The cost-effectiveness analysis showed that both HIT and LIT were cost-effective, and LIT was even cost-saving compared with doing nothing. HIT was more costly and more effective than LIT, and the cost of each extra QALY gained by HIT was 100,000SEK, which is considered very cost-effective in Sweden. Proactice and reactive services were equally effective at the SNTQ. Point prevalence was 27% and 6-month continuous abstinence was 21% after 1yr. Being smokefree at baseline was the strongest predictor for abstinence at 1yr. Conclusion: Support at high as well as low intensity in a clinical dental setting in Sweden and at the SNTQ was effective in achieving smoking cessation. Both high-and low-intensity interventions were very cost-effective in a clinical dental setting.

Shaping Reduced Smoking in Smokers Without Cessation Plans

Experimental and Clinical Psychopharmacology, 2005

Most smokers do not plan to quit in the next 6 months. The authors previously demonstrated that percentile schedules shape lower breath carbon monoxide (BCO) levels in smokers trying to quit (R. J. Lamb, A. R. Morral, K. C. Kirby, M. Y. Iguchi, & G. . In that study, the authors set reinforcement criteria based on the 9 most recent samples. In this study, the authors examined whether a more responsive procedure using the 4 most recent samples is more effective in smokers not trying to quit. Following institution of the contingencies in both groups, BCO levels were substantially reduced, and readiness to quit and cessation self-efficacy increased. However, more individuals in the 4-sample window group achieved a BCO level below 4 ppm, indicating recent abstinence. These individuals did so more rapidly and for a greater number of visits.
