The aim of the present study was to investigate the role of metacognition as a mediator of the relationship between smoking dependence and depression/anxiety/ negative impact of life experiences. A sample of 202 adult smokers completed the following questionnaires: Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Life Experiences Survey (LES), Meta-Cognitions Questionnaire-30 (MCQ-30), and Fagerström Test of Nicotine Dependence (FTND). The path analyses were used to test a mediation model in which depression, anxiety, or negative impact of life experiences was the predictor of metacognition, which in turn was a predictor of smoking dependence. Twelve mediation models were tested using total scores of metacognition, and its factors including positive beliefs about worry, negative beliefs about worry, lack of cognitive confidence, beliefs about need to control thoughts, and cognitive self-consciousness as mediator variables. The models included depression, anxiety, or negative impact of life experiences as independent variables; and smoking dependence as dependent variable. The results suggested that neither total metacognition score nor the individual metacognitive dimensions did mediate the relationship between smoking dependence and depression/anxiety/negative impact of life experiences. The results and limitations, as well as the implications of these findings, were discussed by referring to the relevant literature.
