    Journal: Nicotine Tob Res; 2012 Oct; 14(10):1197-204. PubMed ID: 22387995.
    Abstract:
    INTRODUCTION: Rates of quitting smoking remain stagnant, and thus it is becoming increasingly important to identify determinants of successful quitting behavior. The primary purpose of the current study was to examine predictors of quit attempts and 7-day point prevalence abstinence in a large nationally based sample. The study population consisted exclusively of smokers with minimal interest in quitting in the immediate future, for whom the need to identify facilitating factors of cessation is highly significant. METHODS: Participants consisted of 849 smokers participating in a nationwide population-based randomized controlled trial (RCT) to promote quit attempts and cessation; all participants were not currently interested in cessation. RESULTS: After adjusting for treatment group, and using a multivariate logistic approach, a combination of motivational and self-efficacy variables consistently predicted quit attempts, regardless of how quit attempts were defined (i.e., any self-defined vs. 24 hr). Additionally, a greater number of previous quit attempts significantly predicted making future quit attempts. In terms of achieving short-term abstinence, regardless of whether analyses were restricted to individuals who made prior quit attempts or not, self-efficacy emerged as the only significant consistent predictor. CONCLUSIONS: Unlike previous studies, we did not find strong evidence suggesting unique predictors for making a quit attempt compared with achieving abstinence. Our findings demonstrate that even among smokers not currently interested in quitting, self-efficacy and motivation are key factors in the cessation process. Overall, the findings have important implications, as they highlight factors to target for future treatment.
