This study was to evaluate the effectiveness of the first proactive Quitline service for smoking cessation in Korea and determine the predictors of successful smoking cessation. Smoking participants were voluntarily recruited from 18 community health centers. The participants were proactively counseled for smoking cessation via 7 sessions conducted for 30 days from November 1, 2005 to January 31, 2006. Of the 649 smoking participants, 522 completed 30 days at the end of the study and were included in the final analysis. The continuous abstinence rate at 30 days of follow-up was found to be 38.3% (200/522), in the intention-to-treat analysis. Compared with non-quitters, quitters were mostly male, smoked <20 cigarettes/day, had started smoking at the age of >or=20 yr, and were less dependent on nicotine. Based on the stepwise multiple logistic regression analysis, the significant predictors of successful smoking cessation were determined to be male sex, low cigarette consumption, and older age at smoking initiation. We investigated the short-term effectiveness of the Quitline service and determined the predictors of successful smoking cessation.

    ABSTRACT: Much is known about the predictors of success in quitting smoking. In particular, nicotine dependence, but not strength of motivation to stop, appears to predict abstinence. However, to date, studies have come almost exclusively from Western countries. More data are needed on the cross-cultural generalizability of these findings. One hundred and ninety-eight smokers attending 5 stop-smoking clinics in Malaysia completed a questionnaire prior to their target quit date and were followed up 3 months after this date. Predictors included sociodemographic variables, smoking patterns, past history of quitting, characteristics of current quit attempt, and smoking motives as well as nicotine dependence (Fagerström Test for Nicotine Dependence [FTND]) and self-rated strength of motivation of stop. At 3-month follow-up, 35.4% (95% CI: 28.7-42.0) of participants reported being abstinent. A backward elimination multiple logistic regression identified a number of significant predictors of success, including strength of motivation to stop (adjusted odds ratio [OR]: 3.05, 95% CI: 1.28-7.25). FTND did not predict success. Motivation and nicotine dependence may play different roles in explaining variation in ability to stop smoking in different cultures.

    ABSTRACT: There is a lack of studies on Quitline user satisfaction and its potential value to aid in understanding user demand and improve Quitline services. This study evaluated Quitline user satisfaction and its impact on smoking cessation, in order to assess the service's quality and performance in the Republic of Korea. Between 2007 and 2009, 3,054 Quitline users were invited to participate in an investigation of user satisfaction and its impact on successful smoking cessation. Information on gender, age, education level, body mass index, nicotine dependency, the presence of a quit supporter and alcohol consumption were collected upon Quitline registration. Multiple logistic regression analysis was applied to identify the impact of user satisfaction on cessation maintenance, and an importance-performance (IP) analysis was used to identify the aspects of Quitline that need improvement. Satisfaction was highest among Quitline users who maintained smoking cessation for 1 year. Quitline users who were satisfied with the contents of counseling and the coaching protocol had an increased probability of successful smoking cessation. According to the IP analysis, coaching skill was the key driver of user satisfaction, while service accessibility, the contents of counseling, and the coaching protocol were factors that need to be improved with some urgency. The present study revealed low user satisfaction for the contents of counseling and the coaching protocol, which would need to be improved with some urgency to increase Quitline performance in Korea. Continued evaluation of Quitline user satisfaction could be a useful tool to understand user demand and implement improvements accordingly.
