Five-factor personality traits as predictor of the onset and the frequency of smoking in primary and secondary school children.

Two studies examined five-factor personality traits as predictors of the onset of smoking and the frequency of smoking among primary and secondary school children. Study 1 was conducted on 508 primary school girls and 512 boys, aged from 10 to 16 years. There were no gender differences regarding the onset of smoking. Cox Proportional-Hazards Regression analyses showed that five-factor personality traits significantly predicted the onset of smoking in both samples. Neuroticism significantly predicted earlier and conscientiousness later onset of smoking in girls, while neuroticism and extraversion predicted earlier and conscientiousness later onset of smoking in boys. Study 2 examined the relationship between five-factor personality traits and smoking frequency on 121 secondary school boys and 209 girls. MANOVA conducted on the sample of boys did not show any significant effects of personality traits on smoking frequency. However, on the sample of girls, extraversion and consciousness exerted significant effects on the frequency of smoking. Extraversion was significantly higher and consciousness lower in girls who smoked more frequently compared to girls who did not smoke. The results are discussed in the context of life- history theory and the role of personality traits in developmental changes related to adaptation in adolescence.
