Background. Smoking is one of the most important public health problems among young people. Potential risk factors that may cause vulnerability to smoke in youth should be well known and investigated. The aim of the present study was to evaluate the associations of current smoking behavior and future smoking intention with high-risk personality traits for substance abuse in a clinical sample of Turkish adolescents, and also evaluate nicotine dependence and smoking characteristics with the personality traits in a subsample of regular smokers.

Methods. A cross-sectional study was adopted in which 196 participants took part (aged 14-18 years with a mean of 16.7 years). The assessment consisted of a sociodemographic questionnaire that also questions current smoking behavior and future smoking intention; and additionally, two self-administered instruments including the Substance Use Risk Profile Scale (SURPS) for all participants, and Fagerström Test for Nicotine Dependence (FTND) for only regular smokers.

Results. Regular smokers scored higher than never smokers on the lack of self-contentment subscale of SURPS (F(2)=3.30, p=.039). Future smoking intention was found to be associated with nicotine dependence (F(3)=6.67, p=.001). Regular smokers with high levels of nicotine dependence had higher levels of impulsivity and smoked more cigarettes per day than those with low levels of nicotine dependence (t=2.489, p=.017; and t=3.530, p=.001, respectively). The structural equation models (SEM) were created based on these results and the personality theory for substance abuse. The SEM results showed that the first evidence that lack of selfcontentment positively influences regularly smoking behavior and impulsivity positively influences future smoking intention through nicotine dependence.

Conclusions. Lack of self-contentment and impulsivity may mediate the transition from current smoking behavior to future tobacco use disorders in Turkish adolescents. The assessment and intervention of selfdiscontentment and impulsivity can be beneficial in reducing the current smoking behavior in Turkish adolescents.
