IntroductionLong-term smoking cessation is related to decreased mortality and morbidity, 1-3 yet most smokers who achieve short-term abstinence eventually relapse to smoking. Among self-quitting smokers, the relapse rate may be as high as 95%. 4 Among smokers receiving cessation treatment, 70% relapse. 5 Even among smokers who successfully abstain for one full year, 10% eventually return to regular smoking. 6 Consequently, effective interventions aimed at relapse prevention (RP) are essential for long-term cessation and decrease in smoking-related illness.Cognitive behavioral counseling combined with pharmacotherapy is the most effective evidence-based approach to smoking
AbstractIntroduction: Relapse prevention (RP) remains a major challenge to smoking cessation. Previous research found that a set of self-help RP booklets significantly reduced smoking relapse. This study tested the effectiveness of RP booklets when added to the existing services of a telephone quitline. Methods: Quitline callers (N = 3458) were enrolled after their 2-week quitline follow-up call and randomized to one of three interventions: (1) Usual Care: standard intervention provided by the quitline, including brief counseling and nicotine replacement therapy; (2) Repeated Mailings (RM): eight Forever Free RP booklets sent to participants over 12 months; and (3) Massed Mailings: all eight Forever Free RP booklets sent upon enrollment. Follow-ups were conducted at 6-month intervals, through 24 months. The primary outcome measure was 7-day-point-prevalence-abstinence. Results: Overall abstinence rates were 61.0% at baseline, and 41.9%, 42.7%, 44.0%, and 45.9% at the 6-, 12-, 18-and 24-month follow-ups, respectively. Although RM produced higher abstinence rates, the differences did not reach significance for the full sample. Post-hoc analyses of at-risk subgroups revealed that among participants with high nicotine dependence (n = 1593), the addition of RM materials increased the abstinence rate at 12 months (42.2% vs. 35.2%; OR = 1.38; 95% CI = 1.03% to 1.85%; P = .031) and 24 months (45% vs. 38.8%; OR = 1.31; 95% CI = 1.01% to 1.73%; P = .046). Conclusions: Sending self-help RP materials to all quitline callers appears to provide little benefit to deterring relapse. However, selectively sending RP booklets to callers explicitly seeking assistance for RP and those identified as highly dependent on nicotine might still prove to be worthwhile.
