Feelings of stigmatization, worrying, and psychological distress are common consequences for patients with psoriasis. However, research on the prospective influence of psychosocial factors on psoriasis symptom severity is scarce. Thus, in this study, it is researched if feelings of stigmatization, worrying, and psychological distress are related to the exacerbation of psoriasis symptoms six and twelve months later. Method. This prospective study examined through four multiple regression analyses if the predictors stigmatization, worrying, and psychological distress influenced clinician-assessed and self-administered psoriasis severity after six and twelve months. The type of dermatological treatment and baseline disease severity were included as control variables. Data was collected among 49 psoriasis outpatients using an extensive questionnaire containing multiple self-report questionnaires and through clinician-assessed psoriasis severity. This was conducted at three time points: baseline, at six months, and twelve months. Results. Solely for one predictor a significant effect was found, indicating that higher feelings of stigmatization during baseline measurement predicted lower self-administered psoriasis severity after 6 months (ß = -.38, t = -2.25, p = .03) No other significant effects were found for any predictor, regardless of the clinician-assessed or self-administered severity or the time point (all p ≥ .06). There were predominantly no to small effect sizes found (-.36 ≤ r ≤ .30). Conclusion and discussion. The results of this study cannot substantiate the effect of perceived stigmatization, worrying, and psychological distress on psoriasis severity later. However, a lack of power, the extended interval between measurements, and low mean baseline scores can partly explain the lack of results. Future research should enhance their research design by considering more control variables such as treatment adherence, alcohol consumption, visibility of the lesions, and coping strategies. Besides, a broader range of disease severity should be included. As psoriasis has a serious psychological impact, it is worthwhile to continue the research on the effect of psychosocial factors on psoriasis severity. Previous research suggests the existence of an effect, and establishing this could enhance and increase the use of tailored psychological interventions in the treatment of patients diagnosed with psoriasis. This subsequently can contribute to alleviating their disease burden.Show less

This research has shown that although the differences might be small, they are of crucial importance in how a PWA is perceived in these countries and how these notions have changed over time; from PWA being revered in pre-colonial Yorubaland and the old Kongo Kingdom, to today’s experiences of stigma and discrimination in name-calling, mutilations, and killings. Similarly, a stark contrast also exists amongst some of the countries – from PWA in Benin being revered, to PWA fearing for their lives in Tanzania due to a higher demand for PWA body parts to be used in witchcraft. Tanzania is also the African country that has garnered the most international attention for its treatment of PWA, and although the government and the state attempt to limit the extreme discrimination, it continues to persist. Nevertheless, it is important to keep in mind that the problems of stigma and discrimination as experienced by PWA are not limited to Tanzania, but exist all over the African continent.Show less
