Are Psoriasis Patients More Likely to Have Type D Personality?

Type D (distressed) personality is characterized by a combination of high levels of negative affect and social inhibition, has been named as a risk factor for some chronic diseases, and is associated with low levels of Health-related Quality of Life (HRQOL). Personality is a mediator between the stress produced by the environment and the development and course of some somatic diseases. This led researchers to postulate that Type D personality could be more prevalent among patients with moderate-to severe psoriasis and could additionally contribute to lower HRQOL.

A group of 80 patients with moderate-to-severe psoriasis and 80 healthy controls were assessed using the DS14 personality test. Then HRQOL was evaluated according to The Short Form Health Survey (SF-36) which consists of 36 items that query patients on physical function, bodily pain, general health, vitality, social function, emotional role and mental health.

DS14 results showed that patients with psoriasis had a higher prevalence of type D personality compared to their healthy counterparts. The authors found a significant increase in anxiety and depression in patients with psoriasis and personality Type D. Anxiety, stress and cortisol are well-known aggravating factors for psoriasis. Type D personality was also associated with lower levels of HRQOL in this small sample. The authors suggest that the presence of Type D personality significantly impairs general HRQOL, and psoriasis HRQOL. While more research is needed to confirm these preliminary findings, Type D personality is quickly and easily assessed and may help identify psoriasis patients who are psychologically more vulnerable and show a poorer HRQOL. These individuals could derive noteworthy benefits from psychotherapeutic interventions.
