Association between personality traits and tobacco cessation: A retrospective observational study

Background: Personality traits may influence tobacco cessation success. Aim: To compare personality traits (Big Five) between quitters and non-quitters at a Tobacco Cessation Clinic. Methods: Retrospective review of clinic records (n=3,524). Data extraction included Big Five scores and cessation stage at 1 week, 1 month, 3 months. Statistical comparisons performed using SPSS. Results: At follow-up, 122 patients achieved maintenance. Quitters had higher conscientiousness (mean 3.9), agreeableness (3.7) and emotional stability (3.6) vs non-quitters. Neuroticism higher in non-quitters. Conclusion: Personality profiling (especially conscientiousness and emotional stability) may inform personalized cessation interventions.
