Abstract Objectives: This cross-sectional study explored personality traits of individuals receiving treatment in a private clinic for an eating disorder (ED) compared to those receiving treatment for a dual diagnosis (DD; defined as an addiction to illegal drugs and/or alcohol along with a mental illness, in this case an ED). The aims of this study were to: (a) assess the personality profiles and differentiating traits between the ED and DD groups, (b) analyze differences in personality traits of restrictive ED versus bingeing ED profiles, and lastly (c) compare the individuals Temperament and Character Inventory-Revised (TCI-R) results to their personality clusters as per the Diagnostic and Statistical Manual of Mental Disorders – 5th edition (DSM-5). Methods: The TCI-R is a self-report questionnaire consisting of seven scales, each with their own subscales, which provide a fuller understanding of each temperament and character trait evaluated. This questionnaire was given to patients (n = 67) receiving treatment at a private institute specialized in eating disorders in Barcelona, Spain and the surrounding areas, along with the State-Trait Anxiety Inventory (STAI), Beck Depression Inventory-II (BDI-II), and the Barratt Impulsiveness Scale-11 (BIS-11). These subsequent questionnaires were given as they are often found to be comorbidities of ED. Results: The ED group (n = 41), regarding the TCI-R scales, showed higher scores in harm avoidance (HA), reward dependence (RD), persistence (P), cooperativeness (C) and self-directedness (SD). Whereas, the DD (n = 26) group, showed higher scores in novelty seeking (NS) and self-transcendence (ST). Also, there was a significant positive correlation between the DD group and the extravagance (NS3) subscale of novelty seeking across models. When comparing the two ED groups, the restrictive profile (RP) to the bingeing profile (BP), there were significant negative correlations in the TCI-R subscales of dependence (RD4) and perfectionism (P4) whereas there were positive correlations in the TCI-R subscale of responsibility (SD1). Conclusions: These results support previous studies and help to appraise differences in personality traits between specific groups in a clinical setting.

比较饮食障碍患者与双重诊断患者的人格特征

摘要目标：这项横断面研究探讨了在私人诊所接受饮食失调 (ED) 治疗的个体与接受双重诊断 (DD；定义为对非法药物和/或酒精成瘾) 治疗的个体的人格特征。患有精神疾病，在这种情况下是 ED）。本研究的目的是：(a) 评估 ED 和 DD 组之间的个性特征和区分特征，(b) 分析限制性 ED 与暴食 ED 特征的个性特征差异，最后 (c) 比较个体的气质根据《精神疾病诊断和统计手册》第 5 版 (DSM-5)，将性格量表 (TCI-R) 结果修订为他们的人格集群。方法：TCI-R 是一个自我报告问卷，由七个量表组成，每个都有自己的子量表，可以更全面地了解所评估的每种气质和性格特征。这份问卷是针对在西班牙巴塞罗那及周边地区的一家专门研究饮食失调的私立机构接受治疗的患者 (n = 67) 以及状态-特质焦虑量表 (STAI)、贝克抑郁量表-II (BDI- II) 和 Barratt Impulsiveness Scale-11 (BIS-11)。这些随后的问卷是因为它们经常被发现是 ED 的合并症。结果：ED 组 (n = 41) 在 TCI-R 量表方面在避免伤害 (HA)、奖励依赖 (RD)、坚持 (P)、合作 (C) 和自我导向 (SD) 方面表现出更高的分数. 而 DD (n = 26) 组在寻求新奇 (NS) 和自我超越 (ST) 方面表现出更高的分数。还，DD 组与跨模型寻求新奇的奢侈 (NS3) 分量表之间存在显着的正相关。当比较两个 ED 组时，限制性特征 (RP) 与暴饮暴食 (BP) 的 TCI-R 依赖性 (RD4) 和完美主义 (P4) 分量表呈显着负相关，而 TCI 呈正相关-R 责任分量表 (SD1)。结论：这些结果支持先前的研究，并有助于评估临床环境中特定群体之间人格特征的差异。TCI-R 依赖分量表 (RD4) 和完美主义 (P4) 呈显着负相关，而 TCI-R 责任分量表 (SD1) 呈正相关。结论：这些结果支持先前的研究，并有助于评估临床环境中特定群体之间人格特征的差异。TCI-R 依赖分量表 (RD4) 和完美主义 (P4) 呈显着负相关，而 TCI-R 责任分量表 (SD1) 呈正相关。结论：这些结果支持先前的研究，并有助于评估临床环境中特定群体之间人格特征的差异。
