Probing smoking craving with a multidimensional approach: validation of the 12-item French-language version of the Questionnaire on Smoking Urges

BACKGROUND The current study examined the psychometric properties of the 12-item French-language version of the Questionnaire on Smoking Urges (QSU-12), a widely used multidimensional measure of cigarette craving. METHODS Daily smokers (n=230) completed the QSU-12, the Fägerstrom Test for Nicotine Dependence, and items about addiction-related symptoms. Additional participants (n=40) completed the QSU-12 and the Fägerstrom Test for Nicotine Dependence and were assessed for expired carbon monoxide. RESULTS Consistent with studies validating the English version of the scale, confirmatory factor analyses supported a two-factor solution in the French version of the scale. Good scale and subscales reliabilities were observed, and convergent validity was evidenced through relationships with dependence and addiction-related symptoms. CONCLUSION The French-language version of the QSU-12 is an adequate instrument to assess the multidimensional construct of craving in both research and clinical practice.
