Personality traits and substance use disorders: Comparative study with drug user and non-drug user population

Personality traits play a vital role in addictive behaviors, drug addiction in particular. To compare normal and pathological personality traits in drug users and non-drug users. In this comparative study, we employed convenience sampling to recruit drug users (n = 110; 58 men and 52 women), from addiction treatment centers in a selected city in Azarbaijan province, and matched group of non-drug users (n = 110; 58 men and 52 women). The data were collected using demographic information questionnaire, Jakson-5 scale, Temperament and Character Cloninger (TCI), and Personality Inventory for DSM-5-Brief Form (PID-5-BF). The data were analyzed by chi square and multivariate analysis of variance (MANOVA). Two groups were significantly different in normal (r-RST, TCI) and pathological (PID-5) personality models. In TCI model, drug users gained high scores in the dimensions of novelty seeking and harm avoidance; and obtained low scores in the dimensions of reward dependence, persistence, and self-directedness. In r-RST model, they gained high scores in r-BAS and r-fight System; and obtained low scores in r-BIS. Also, in pathological personality model (PID-5), the scores of drug users were high in all of the dimensions except for detachment dimension. Our findings suggest that personality traits are coincidence in drug users. Professional evaluation of drug using patients in order to differentiate normal and pathological personality models of them is recommended. [Display omitted]
