OBJECTIVES: To report on the content development, construct validity, and reliability testing of the Geriatric Self‐Efficacy Index for Urinary Incontinence (GSE‐UI). DESIGN: Prospective cohort study. SETTING: Six UI outpatient clinics in Quebec, Canada. PARTICIPANTS: Community‐dwelling incontinent men and women aged 65 and older. MEASUREMENTS: Thirty‐eight items were generated using a literature search and interdisciplinary panel of experts. Item reduction was achieved through field‐testing with 75 older men and women with UI attending an information session. The final 20‐item draft, measuring older adults' level of confidence in preventing urine loss, was administered to a new group of consecutive patients 1 week before and at the time of their first visit to the UI clinic to enable evaluation of test–retest reliability. A 3‐day voiding diary, quantifying the frequency of UI, and the Incontinence Quality of Life questionnaire were used to test construct validity. RESULTS: One hundred sixteen of 300 eligible patients (39%) participated (mean age±standard deviation 74±6, range 65–87). The GSE‐UI items showed normal distributions and no ceiling effects. Self‐efficacy scores ranged from 16 to 193 (mean 104±41, possible range 0–200) and correlated positively with quality of life scores ( r =0.7, P <.001) and negatively with UI severity ( r =−0.4, P <.001). Internal consistency for the GSE‐UI was 0.94 (Cronbach alpha). Initial test–retest reliability of the 20 items using intraclass correlations ranged from 0.50 to 0.86. CONCLUSION: The GSE‐UI will enable measurement of whether a person's confidence in their ability to prevent urine loss is an important mechanism contributing to improvements in UI.
