Abstract

Objective: Personality traits play a vital role in addictive behaviors, drug addiction in particular. Aim of study: To compare normal and pathological personality traits in drug users and non-drug users. Methods: 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). Results: 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. Conclusion: 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. © 2019 Elsevier Ltd
