Abstract

INTRODUCTION Smoking prevalence remains high in China with a low cessation motivation level, despite the government’s tobacco control efforts. There is a lack of research specifically examining perceptions, attitudes, and behaviors related to smoking cessation in this region, particularly from a theory-based deductive perspective. Utilizing the COM-B (Capability, Opportunity, Motivation-Behavior) model as a theoretical framework, this study aimed to identify facilitators and barriers to smoking cessation among Chinese smokers. METHODS The study employed semi-structured individual interviews with 40 participants. Each interview spanned approximately 30 minutes. The participants, constituting both current and former smokers, were all aged ≥18 years (n=40). Interview data were then examined using a directed content analysis approach. RESULTS Analysis revealed three interrelated themes. Capability: Smokers face challenges when resisting peer pressure and dealing with life after quitting. They also lack knowledge about smoking, quitting techniques, and withdrawal symptoms. Opportunity: Changing societal attitudes towards smoking create opportunities for quitting, but these are hindered by inadequate cessation services and a lack of family support. Motivation: Smokers' motivation to quit is mainly driven by health concerns. Resistance to quitting often stems from the belief that smoking is a personal choice or just a habit. Excessive emphasis on willpower may hinder motivation to quit. CONCLUSIONS To enhance smoking cessation efforts in China, three key aspects should be considered: capability, opportunity, and motivation. Publicity and educational campaigns should target common misconceptions about smoking as a personal freedom, correct the overemphasis on willpower, and widely promote available cessation services. A crucial aspect is shifting societal norms to foster anti-smoking sentiments. Effective strategies may involve using real-life stories to illustrate smoking's health consequences, disseminating information about cessation services in maternity centers, enhancing services through mobile health initiatives, and empowering families to support smokers in their quit attempts.
