Abstract

PURPOSE
The purpose of this study was to evaluate the psychometric properties of the Korean version of the Male Urinary Distress Inventory (MUDI) and Male Urinary Symptom Impact Questionnaire (MUSIQ). PATIENTS AND METHODS: A convenient sample of community-dwelling older men with urinary incontinence participated. A cross-sectional survey design was used for this study. A panel of experts completed the initial translation into Korean and back-translated the MUDI and MUSIQ. Upon establishment of the content and translation equivalence between English and Korean versions of the MUDI and MUSIQ, psychometric properties were evaluated for reliability, concurrent, and construct validity with a sample of 143 older men.
RESULTS
The internal consistencies of both instruments were found to be acceptable, and Cronbach's coefficients were 0.88 for the MUDI-K and 0.92 for the MUSIQ-K. A significant moderate correlation between MUDI-K and MUSIQ-K was found in this study, indicating modest concurrent validity between these 2 instruments (r = 0.56, p < 0.001). For construct validity, the mean scores of the MUDI-K were significantly different for age, marital status, prostate surgery, erectile dysfunction, and depression (p < 0.05). The means scores of MUSIQ-K were significantly different for depression (p < 0.05) only. For both the MUDI-K and MUSIQ-K, 7 factors were extracted, accounting for 68.1% and 72.1% of the variance.
CONCLUSION
Results of this study suggest that the MUDI-K and MUSIQ-K can be used as a reliable and valid measure of health-related quality of life in community- dwelling Korean older men with urinary incontinence.
