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. Material and Method: The questionnaire was translated into Turkish by using appropriate translation steps. The socio-demographic data and the Psoriasis Area and Severity Index (PASI) scores of the patients were recorded. For reliability analysis, internal consistency and test-retest method were used. The Cronbach's alpha coefficient and item-total statistics were calculated for each question and subscales. For validation, the questionnaire was compared with the Dermatology Life Quality Index (DLQI). Results: A total of 161 psoriasis patients were included in the study. For internal consistency, Cronbach's alpha coefficients of all subscales ranged between 0.61 and 0.79 and were calculated as 0.88 for the overall index. In test-retest reliability, the correlation coefficient ranged between 0.366 and 0.775 for each question and were calculated as r=0.854 for the total PDI score (p<0.001). For validity analysis, the relationship between the mean PDI and DLQI scores was researched and a strong statistical correlation between the coefficients was established (r=0.674, p<0.05). Conclusion: Our study indicates that the Turkish version of the PDI has an acceptable reliability and validity for use in Turkish psoriasis patients. [ABSTRACT FROM AUTHOR] |
