Four years stability of type D personality in patients with moderate to severe psoriasis and its implications for psychological impairment

Abstract

Background Psoriasis is a systemic auto-inflammatory disease that is related to an increased risk of organic and psychological comorbidities. Type D is a stable personality trait in healthy subjects but there is no data regarding its stability in patients with moderate-severe psoriasis. Objectives To assess the stability of type D personality in patients with moderate to severe psoriasis as well as assessing the influence of type D personality on anxiety and depression. Methods Prospective cohort study. Forty psoriasis patients with type D personality and sixty-six patients with psoriasis without type D personality were included in the study. Participants completed the DS14 test and HADS at baseline and four years later. Results At baseline, the prevalence of type D personality was 37.7% and at week 208 it was 27.3%. The stability of type D personality was higher in patients with an incomplete education level and in those who were separated/divorced or windowed. During follow-up, 15% of patients developed type D personality. Male sex, having topical treatment, the presence of previous depression, anxiety, and high levels of negative affectivity at baseline increase the risk of developing type D personality. Study limitations Sample size, psoriasis severity restricted to moderate and severe and all patients being under treatment for psoriasis. Conclusions The presence of type D personality varies over time in psoriasis patients. Therefore, type D personality is possibly more a state than a trait phenomenon, modified by environmental factors. Type D personality is associated with a higher risk of anxiety.

Type D Personality Is Associated with Poorer Quality of Life in Patients with Chronic Spontaneous Urticaria: A Cross-sectional Study

“…On the other hand, socio-demographic and disease features are homogeneously distributed between the groups of patients with and without TDp, as has been previously described in other diseases, such as psoriasis ( 15 ). This fact is compatible with the concept of personality as a typical and stable characteristic of the subject, which may be unaffected by most life experiences ( 26 ). However, there is controversy about the possibility that personality may change throughout a person’s life ( 29 ).…”

“…The obtained prevalence for TDp seems to be similar to those described for the general population (13–34%) ( 10 , 25 ). Several reports show a higher prevalence of TDp in other diseases: Psoriasis (38.4%) ( 26 , 27 ), myocardial infarction (50.7%) ( 28 ), and brain cancer (34.1%) ( 11 ) are some examples. This might be explained by the fact that, although CSU is a chronic disease, the total duration of the disease, which in most cases is self-limiting ( 1 ), is not sufficient to lead to substantial changes in personality.…”

Type D Personality as a Marker of Poorer Quality of Life and Mood Status Disturbances in Patients with Skin Diseases: A Systematic Review

“…On the other hand, the impact of this type of personality on the quality of life of patients with acne was also studied by Chilicka et al ( 2 ), who found that both components of type D personality (NA and SI) were associated with lower life satisfaction. Krowchuk et al ( 22 ) studied the impact of acne in adolescent patients, showing that up to 53% of patients had self-reported SI due to the acne. No differences were found between males and females.…”

The Influence of Personality Traits on Specific Coping Styles and the Development of Posttraumatic Stress Symptoms following Acute Coronary Syndrome: A Cluster Analytic Approach

“…Associations of PTSD symptoms with the personality traits were only found at 3-month follow-up, except for resilience. This might be because alexithymia and TDP might partially reflect responses to the traumatic event and change over time [31,32]. However, these previous studies were performed in individuals with different types of trauma.…”
