Introduction. Psoriasis is a systemic skin disease characterized not only by external manifestations and unpleasant subjective sensations, but also by a significant deterioration in the quality of life. To date, many tools have been developed to assess the quality of life of patients with psoriasis, which creates the problem of choosing the necessary questionnaire, taking into account the age, area and severity of the lesion. The purpose of this systematic review is to analyze international experience in including the assessment of the quality of life in patients with psoriasis in the system of monitoring the health status of the population. Materials and methods. We searched four databases: PubMed, Cochrain, Google Scholar, MedLine. Literary sources from the last 20 years were observed. Results. A total of 68 sources that met the criteria were selected and included in the review. We identified 32 questionnaires assessing the quality of life for adult patients and 9 questionnaires aimed at children and adolescents. The questionnaires for psoriatic arthritis and psoriasis of the scalp can be singled out separately. Most of the studies included in this review were conducted in the United States and Western Europe. Conclusion. It turned out that most often when assessing the quality of life in adults diagnosed with psoriasis, the dermatological index of quality-of-life DLQI is used, in children and adolescents the children's dermatological index of quality-of-life CDLQI.
