Psoriasis is a common skin disease that affects the physical, psychological and social wellbeing of patients. Several studies have assessed the health-related quality of life (HRQoL) of patients with psoriasis in different population with big variations. We aimed to investigate, for the first time, the impact of psoriasis on the quality of life of patients in Afghanistan. This was a prospective observational study conducted at the dermatology department of a teaching hospital from April 2018 to May 2019. Patients aged ≥ 16 years with plaque psoriasis were included in the study. The Psoriasis Disability Index (PDI) was used for the assessment of HRQoL. The Psoriasis Area and Severity Index (PASI) was used to define the severity of disease. Appropriate tests were performed using SPSS. A total of 174 patients with psoriasis were included in the study; 89 were male (51.1%) and 85 were female (48.9%). The mean (SD) age of the patients was 27.7 (13.2) years, and the mean (SD) duration of the disease was 3.2 (4.7) years. Mean (SD) PASI score was 13.3 (7.8), while the mean (SD) total PDI was 9.6 (3.7); there was a strong correlation between total PDI and PASI score (r = 0.751, P < 0.001). The mean total PDI was higher in moderate-to-severe psoriasis, female patients, at a younger age and those who were single. Our study highlights that PDI was highly correlated with PASI. Furthermore, quality of life was more often affected in females, those aged < 40 years and those who were single.
