RESUMEN
BACKGROUND AND OBJECTIVES: Persistent smoking behaviours are associated with numerous motives, explaining the absence of a single treatment for quitting. One of these motives may include that of identification. The threat of losing their smoker's identity may represent a significant obstacle to lasting abstinence. The objective of this study is to design a specific identity questionnaire and examine correlations between the degree of smoking identity and persistent smoking. METHODS: Patients attending a smoking cessation seminar completed the Modified Reasons for Smoking Scale, Barriers to smoking cessation checklist and our 6-item Smoker's Identity Scale (SIS) (n = 170 questionnaires). RESULTS: SIS showed good internal consistency, calculated by a Chronbach test (α = .785) with no redundant questions. There was a correlation between strong tobacco dependence (measured by the Fagerström questionnaire) and strong smoking identity (p = .0001). Strong identity was associated with less confidence in quitting at both 1 and 6 months (p = .037 and p = .002, respectively). We showed that identity represents an obstacle to quitting in 32% of our patients and is associated with decreased confidence in quitting. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Our study shows that measuring identity in smokers who wish to make a quit attempt may help to identify specific obstacles to abstinence. This may also help in elaborating improved quitting strategies and patient management. Further research is necessary to confirm these results.
