Psoriasis may imply a remarkable psychological impairment, which can influence patient's personality. The Type D personality is defined by the combination of social inhibition and negative affectivity. Furthermore, Type D personality has been associated with impaired health-related quality of life (HRQOL) and increased cardiovascular risk, both facts being associated with moderate to severe psoriasis.
To explore the prevalence of Type D personality in moderate to severe psoriasis patients; To analyse the relationship between Type D personality and the most common physical and psychological comorbidities in moderate to severe psoriasis and To explore the impact of Type D personality on HRQOL.
A prospective comparative study matched to age and sex. Eighty patients with moderate to severe psoriasis and 80 healthy volunteers were included in the study. The participants completed the DS14 test, the Massachusetts General Hospital-Sexual Functioning Questionnaire, the Hospital Anxiety and Depression Scale, the SF-36 and the Psoriasis Disability Index.
The prevalence of Type D personality was higher in patients with moderate to severe psoriasis as compared to healthy volunteers: 38.7% vs. 23.7%, P < 0.001. Psoriasis patients with Type D personality had a 3.2-fold risk of anxiety when compared to patients without Type D personality; odds ratio 3.2 (1.3-8.83 P = 0.01). Type D personality was significantly associated with an impaired general, sexual and psoriasis-related HRQOL (P < 0.01).
Because Type D personality could represent a frequent type of personality among individuals with moderate to severe psoriasis, it could serve as a 'marker' of more psychologically vulnerable patients, probably related to dysfunctional coping strategies. The Type D personality could represent a profile more frequently encountered among patients with psoriasis, and might therefore help identify subjects physiologically more vulnerable to disease, most likely due to inadequate adaptation mechanisms.
银屑病可能意味着明显的心理损伤，这会影响患者的个性。D 型人格是指社交抑制和消极情感的组合。此外，D 型人格与健康相关的生活质量（HRQOL）受损和心血管风险增加有关，这两个因素都与中度至重度银屑病有关。
探讨中度至重度银屑病患者 D 型人格的患病率；分析 D 型人格与中度至重度银屑病常见的躯体和心理合并症之间的关系；探讨 D 型人格对 HRQOL 的影响。
这是一项前瞻性的对照研究，与年龄和性别相匹配。共纳入 80 例中度至重度银屑病患者和 80 名健康志愿者。参与者完成了 DS14 测试、马萨诸塞州总医院性功能问卷、医院焦虑和抑郁量表、SF-36 和银屑病残疾指数。
与健康志愿者相比，中度至重度银屑病患者中 D 型人格的患病率更高：38.7%比 23.7%，P<0.001。与非 D 型人格患者相比，患有 D 型人格的银屑病患者发生焦虑的风险增加 3.2 倍；优势比 3.2（1.3-8.83，P=0.01）。D 型人格与一般、性和银屑病相关的 HRQOL 受损显著相关（P<0.01）。
由于 D 型人格可能是中度至重度银屑病患者中常见的人格类型之一，因此它可能是更具心理脆弱性的患者的“标志物”，可能与功能失调的应对策略有关。D 型人格可能是银屑病患者中更常见的一种人格类型，因此可以帮助识别生理上更容易患病的患者，这可能是由于适应机制不足。
