Peyronie's Disease Questionnaire (PDQ): Spanish translation and validation.

The Peyronie's Disease Questionnaire (PDQ) is a 15-question self-reported questionnaire that evaluates the severity and physical and psychosexual issues of Peyronie's disease (PD) symptoms in three scales: "psychological and physical symptoms," "penile pain," and "symptom bother. " Previous studies validated the PDQ US version and confirmed its test-retest reliability and responsiveness. The aim is to translate and validate the Spanish version of the PDQ to be used in the clinical practice and in PD research studies in Spain. A non-interventional, observational study with 160 PD patients was conducted. Patients included from four healthcare centers in Spain and completed the PDQ in two study visits separated for a period of 4-7 days from March 2018 to June 2019. Patients received no type of treatment or intervention. Different statistical tests were applied to the data in order to validate the structural and construct of the PDQ, as well as its internal reliability, temporal stability reliability, reliability between observers, and test-retest reliability. Cronbach's alpha over 0.9 showed good internal consistency. We found an ICC agreement of 0.82 (test-retest) for the three scales of the Spanish version of the PDQ, which demonstrates good reliability. When comparing Visit 1 and Visit 2 questionnaires mean scores, the PDQ showed non-significant differences, as expected because no intervention or treatment was administered to the patients between visits. Translation and validation of the PDQ for the Spanish population makes available a valid, useful, and reliable tool to properly evaluate quality of life of men suffering PD.
