Patients with Substance use disorder have distinct personality traits, they were high score in novelty seeking (NS) and sensation seeking and lower in Self-directedness and higher in Self-transcendence, so we aim to investigate the relationships of temperament and characteristics with related some variables such as substance of choice.
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.
物质使用障碍患者具有独特的人格特质，他们在寻求新奇（NS）和感觉寻求方面得分较高，而在自我导向和自我超越方面得分较低，因此我们旨在研究气质和特征与相关变量之间的关系，如选择的物质。
在马什哈德医科大学进行了一项病例对照研究，共纳入 70 名物质使用障碍患者和 70 名对照。
采用病例对照设计，在马什哈德医科大学对一组 70 名物质使用障碍患者和 70 名对照进行了研究。所有参与者均完成了 240 个问题的气质与性格量表修订版（TCI-R）。采用多元协方差分析（MANCOVA）比较气质和性格特征与物质使用模式之间的关系。
与健康个体相比，病例组的奖赏依赖、坚持、自我导向、合作和自我超越得分明显较低（P<0.05）。相反，病例组的寻求新奇得分明显较高（P<0.05）。另一方面，两组研究对象的回避伤害得分无显著差异（P=0.637）。
物质使用障碍患者中较高的 NS 是常见的，不同的特征和气质会选择不同的物质组合。
