A critical review of Quality-of-Life Scales for Psoriasis.

Psoriasis can have a major impact on the lives of patients who have psoriasis and many different methods are described to measure this effect. This article describes four general health measures, six dermatology-specific measures, four psoriasis-specific measures, and four utility measure concepts that are used in psoriasis. For each of these, the extent of validation, including reliability of each measure and correlation with other measures, is described. The experience of use of each measure is summarized and key references listed. Advice is given concerning strategy for choosing which measures to use.

Two decades experience of the Psoriasis Disability Index.

The Psoriasis Disability Index (PDI) was formed 20 years ago. Since its introduction it has been used widely as a tool for assessment of quality of life in psoriasis. This paper reviews its use in 23 peer-reviewed articles and over 35 published abstracts, and describes its use in conjunction with other general and psoriasis-specific quality of life assessments, and with a range of physical and psychological measures. The PDI is effective in demonstrating the effects of interventions, both of treatments and in health service research. The PDI has been translated into at least 16 languages and has been used in published research in 20 countries.
