Rôle des croyances rationnelles et irrationnelles concernant la motivation à l'arrêt du tabac

While smokers may have a relatively rational and lucid impression of their smoking problem, IBs, including those regarding weight gain, may have a negative impact on the ability to stop smoking. The effect of beliefs about weight gain appears to decrease over time, but the beliefs about smoking, both rational and irrational, appear to persist. Thus, IBs about the fear of weight gain appear to be an obstacle to stopping smoking in the immediate period, and therefore special attention should be given to this aspect by professionals during consultations for smoking cessation. Future research is warranted towards a better understanding of the role of both rational and IBs in smoking cessation, perhaps within a longitudinal framework to ascertain how beliefs can be modified over time with therapy.
