Abstract
Introduction: Smoking cessation studies are often conducted in clinical settings. This study first aims to identify predictive factors involved in smoking relapse and sustained cessation. Secondly, the author examined the psychological components involved in the quitting process that can lead to sustained cessation, which include motivation, perception and changes in behaviour. Lastly, taking the Transtheoretical model (TTM) as the behavioural model under study, the investigator also tested whether this model is applicable in assessing and predicting smoking relapse. Methods: This was a prospective cohort study involving employees from two major public universities in Malaysia. Smoking employees from these workplaces received an invitation to participate in this study. At the start of the treatment, participants completed a questionnaire on their sociodemographic variables and smoking habits as well as the Job Content Questionnaire (JCQ) and the Transtheoretical Model (TTM) Questionnaire. Participants were given behavioural therapy with free nicotine replacement therapy (NRT) as treatment for two months. Subsequently, they were followed up at one week, three months and six months. They were all asked to complete similar sets of questionnaires, and their smoking status was determined. This study used recurrent logistic regressions and survival analysis to study the progression from an initial attempt to quit to smoking cessation or eventual relapse. Results: One hundred and eighty five smoking staff from both universities responded and voluntarily showed interest in quitting. At one week, 55.7% of smokers quit, whereas at three months and six months, the percentage of quitters declined to 14.6% and 13%, respectively. A total of 120 smokers achieved at least 24 hours of abstinence at the end of six months; of these, 80% relapsed. Smoking relapse was shown to decline with time. The majority of relapses occurred within the first two weeks, and most relapses occurred within two months. This study has produced six main findings: 1) most relapses occurred within the first two months of quitting; 2) reduced exposure to other smokers in the workplace can potentially prevent smoking relapse; 3) a good relationship between co-workers and their resultant support are important factors in smoking cessation in the workplace; 4) healthcare professionals can help smokers with low motivation to quit; 5) positive changes in perception following counselling sessions are associated with quitting, and finally; 6) the results of the TTM suggest that this model can be used to predict smoking relapse. This is the only work thus far that extends the applicability of the TTM as a model for smoking relapse among smokers attending face-to-face counselling sessions. Conclusions: Workplace social support, workplace environmental tobacco exposure, motivation change and perception change are important contributing factors in achieving and maintaining six-month abstinence. Furthermore, conducting a small-scale intensive workplace programme for smokers may return a potentially good outcome on cessation rates, but it may lead to poor long-term success rate due to smoking relapse. Hence, a strict workplace smoking ban is recommended to ensure greater and longer quit maintenance among former smokers.
