Elevated prevalence of Type D (distressed) personality in moderate to severe psoriasis is associated with mood status and quality of life impairment: a comparative pilot study.

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.
