Background: The association between experience with “National Smoking Cessation Services (NSCS)” and intention to quit was investigated among adult smokers to evaluate its effects and provide better services.
Methods: From the Tillion Internet research panel, 2,000 tobacco users aged 19-65 years old were sampled with country representativeness and invited to participate in an online survey on November 2018. Information on general characteristics, smoking behaviors, experience with cessation services, and intention to quit were gathered. A Chi-square test and multiple logistic regression analysis were used to estimate the association.
Results: In total, 19% and 71% of 2,000 current adult smokers intended to quit within 1 and 6 months. Additionally, 21.8% had ever used cessation services. Smoking fewer than 10 cigarettes per day and ever using cessation services increased the intention to quit within one month, and this increase was furthered when they experienced the effect of cessation services (OR 2.78, 95% CI 2.07-3.73). There was a similar effect on intention to quit within six months. In the subgroup analysis of those ever using NSCS, intention to quit within six months was greatly increased when the subjects experienced reinforcement of willingness or self-confidence to quit from previous use of cessation services (OR 9.34, 95% CI 2.71-32.16).
Conclusion: Ever using NSCS and experiencing the reinforcement of self-confidence to quit from NSCS use increased the intention to quit among current adult smokers. An organized effort appears necessary to encourage more smokers to access cessation services and to intensify the program for self-confidence to quit for service improvement.
