Translation Validity and Reliability of I-PSS Korean Version / 대한비뇨기과학회지

ABSTRACT

Recently developed International Prostate Symptom Score(I-PSS) is highly recommended for the evaluation of urinary symptoms in benign prostatic hyperplasia(BPH) and many linguistic translations have been made. English version of I-PSS was translated into Korean. Three groups of urologists and ordinary people participated for the translation and back-translation of I-PSS. A Korean version was finalized and translation validity was assessed by a survey with 48 English speaking Korean aged men. Test-retest reliability was confirmed by an another questionnaire survey with 76 aged men. Translation of I-PSS into Korean was valid. The I-PSS Korean version was internally consistent and sensitive as well as specific for the discrimination of symptomatic groups. Also test-retest reliability was acceptable.
