The Turkish Version of the Psoriasis Disability Index: A Validation and Reliability Study

Abstract

Background and Design: Several instruments are available for assessing impairment and disability associated with psoriasis. The first psoriasis-specific quality of life questionnaire, Psoriasis Disability Index (PDI), has been translated to many different languages and used in studies all around the world. The aim of this study was to translate the PDI into Turkish and to validate the Turkish version of the PDI and its use for Turkish psoriasis patients, as well as to examine the specific contribution of demographic and clinical features to the PDI.
