A case-control study enrolling 70 Substance use disorder patients and 70 controls was conducted at Mashhad University of medical sciences. Using a case-control design, a group of 70 Substance use disorder patients and 70 controls was conducted at Mashhad university of medical sciences. All participation completed the 240 questions of Temperament and Character Inventory-Revised (TCI-R). Multivariate analysis of covariance (MANCOVA) was employed to compare the relationship between temperament and character traits and patterns of substance use. The scores of reward dependence, persistence, self-directedness, cooperativeness, and self-transcendence were significantly lower in the case group compared to healthy individuals (P < 0.05). In contrast, the score of novel seeking was significantly higher in the case group (P < 0.05). On the other hand, harm avoidance was not significantly different between the two studied groups (P = 0.637). Higher NS in patients with substance use disorder is common and different traits, and temperaments would choose different substance combinations.
