Development and testing of a measure of health-related quality of life for men with urinary incontinence.
OBJECTIVE
To describe the development and psychometric testing of male versions of the Urogenital Distress Inventory (UDI) and Incontinence Impact Questionnaire (IIQ).


METHODS
Instrument development.


METHODS
Urology clinic at a large urban Veterans Affairs Medical Center.


METHODS
Convenience sample of English-speaking community-dwelling male urology clinic patients who acknowledged concerns about urine leakage.


METHODS
Content experts and male clinic patients evaluated items for clarity and fit. Revised instruments were administered to 153 participants. Data were analyzed to examine issues of feasibility of administration, internal consistency reliability, and validity.


RESULTS
Modal completion time for the Male Urogenital Distress Inventory (MUDI) (27 items) and Male Urinary Symptom Impact Questionnaire (MUSIQ) (32 items) was 20 minutes. Cronbach's coefficients were.89 for the MUDI and.95 for the MUSIQ. Total MUDI and MUSIQ scores were moderately correlated (r =.59, P <.001). Mean MUDI and MUSIQ scores varied significantly with self-reported desire for socialization, urine leakage, and depression. Principal components analyses suggested the presence of seven factors accounting for 65.4% of the variance in the MUDI and six factors accounting for 72.9% of the variance in the MUSIQ.


CONCLUSIONS
It is feasible to use the MUDI and MUSIQ to measure health-related quality of life in men with continence problems. The scores appeared to be reliable and valid in this racially and educationally diverse sample. Use of the MUDI and MUSIQ may provide more sensitive measurement of the specific effect of urinary incontinence and related symptoms on health-related quality of life in men. Future research should determine reproducibility and responsivity and reexamine the construct validity of these instruments.
