Predicting smoking and nicotine dependence from the DSM-5 alternative model for personality pathology.

Individuals with personality disorders (PDs) have higher morbidity and mortality than the general population, which may be due to maladaptive health behaviors such as smoking. Previous studies have examined the links between categorical PD diagnoses/personality traits and smoking/nicotine dependence, but little is known about how the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition alternative model for personality disorders relates to smoking and nicotine dependence. The current study examined this question in a sample of 500 participants using the Levels of Personality Functioning Scale to assess general personality pathology, the Personality Inventory for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition to measure specific traits, the Fagerström test for Nicotine Dependence to assess nicotine dependence, and questions about current and past smoking to assess smoking status (i.e., current, former, never). Multinomial logistic regression results demonstrated that general personality pathology (Criterion A) was not related to smoking status, and there were no reliable associations between traits (Criterion B) and smoking status. However, correlations showed that higher negative affectivity and disinhibition were related to higher levels of nicotine dependence within smokers. Findings are discussed in regard to previous findings linking personality pathology to smoking/nicotine dependence as well as the general validity of this new personality disorder diagnostic system.
