摘要
OBJECTIVE: To develop a condition-specific measure for assessing the impact of urge urinary incontinence (UI) on the quality of life (QoL) of older persons. DESIGN: A 32-item Urge Impact Scale (URIS) was drafted using content area data from focus groups composed of urge incontinent older persons. Pilot testing in 21 urge incontinent persons (mean age 67.7 years) resulted in the elimination of eight items by internal consistency, skew, and patient response criteria. The resulting scale (URIS-24) was tested for reliability (internal consistency and test-retest correlation) and construct validity (correlation with UI severity from voiding records) in a separate group of 27 urge incontinent persons (89% women, mean age 72 years). Factor analysis of URIS-24 data from the combined 48 persons was used to explore the conceptual structure underlying urge UI-related QoL. SETTING: University-affiliated community-based practice and tertiary hospital. PARTICIPANTS: Community-dwelling women and men, older than age 60 and with urge incontinence at least twice weekly, recruited from newspaper, newsletter, and radio advertisements. RESULTS: Cronbach's alpha for URIS-32 was 0.84, and for URIS-24 it was 0.94. When administered (mean +/- standard deviation) 9.2 +/- 5.1 days apart, URIS-24 had good test-retest reliability for total scores (interclass coefficient = .88. concordance coefficient = .88), and individual item scores at time 2 were within 1 point (on a 5-category Likert scale) of time 1 answers for 89% of responses. URIS-24 scores had modest but nearly significant correlation with the number of UI episodes (r = -0.39, P = .05). Factor analysis revealed a three component structure corresponding to psychological burden, perception of personal control, and self concept. CONCLUSIONS: The URIS-24 is an internally-consistent, highly reproducible tool for the assessment of the QoL impact of urge UI on older persons. It can be used to evaluate QoL impact by specific items as well as by overall score. Compared with other UI-specific QoL measures, the URIS-24 had similar or superior internal consistency, test-retest reliability, and validity, but it is the first measure designed and tested specifically for older persons with urge UI. These results also highlight the multifactorial structure of urge UI-related QoL and the importance of its psychological dimensions.
