Background: Psoriasis is a systemic inflammatory disease capable of creating stigmatization in the form of social exclusion and decrement of psychological conditions. Aim: The aim of the study was to determine the level of stigmatization in patients with plaque psoriasis. Methods: The study included 166 patients with plaque psoriasis (55.6% women and 44.3% men) with Psoriasis Area and Severity Index scores ≤10. The age of the study patients ranged between 18 and 72 years (arithmetic mean = 37.4; median = 38; standard deviation [SD] = 11.0). The mean age at the diagnosis of psoriasis was 21.5 years (median = 20; SD = 9.1) and disease duration varied from 2 to 59 years (arithmetic mean = 15.8; median = 15; SD = 11.3). The study patients completed the Polish version of the 6-item Stigmatization Scale and the 33-item Feelings of Stigmatization Questionnaire and a survey developed by the authors of this study, containing questions about the participants’ sociodemographic characteristics (sex, age, place of residence, marital status, education, employment status) and information about their disease (location of psoriatic lesions, time elapsed since the diagnosis of psoriasis). Results: The mean score for the 6-item Stigmatization Scale for the whole study group was 7.6 out of 18 points (median = 7; SD = 3.8; minimum = 0; maximum = 17). The average score for the 33-item Stigma Feelings Questionnaire in our series was 84.5 out of 165 points (median = 88; SD = 20.9; minimum = 30; maximum = 136). A statistically significant sex-related difference was observed in the 6-item Stigmatization Scale scores, with higher stigmatization levels found in men than in women (p = 0.0082). Moreover, significantly higher levels of stigmatization were observed in countryside dwellers (p = 0.0311) and unmarried persons (p = 0.0321). Patients with a longer history of the disease (≥15 years) scored significantly higher on the 6-item Stigmatization Scale (p = 0.0217) than those in whom psoriasis lasted less long, and presented with higher, at the threshold of statistical significance, scores for the 33-item Feelings of Stigmatization Questionnaire. Conclusions: Stigmatization awareness should be promoted among physicians and psoriatic patients to improve psoriasis management.
