PURPOSE: This study aimed to determine nursing students' knowledge about and attitudes toward patients with urinary incontinence. SUBJECTS AND SETTING: The sample comprised 392 nursing students from 5 educational institutions in Hong Kong; all participants were enrolled in year 4 or 5 of their undergraduate nursing program, and all had completed formal education on urinary incontinence and clinical experience caring for patients with urinary incontinence. METHODS: A cross-sectional survey was conducted in February 2017. Participants completed a 55-item questionnaire that included items querying demographic and pertinent professional background information, along with 2 validated instruments: the Urinary Incontinence Knowledge Scale (UIKS) and the Urinary Incontinence Attitude Scale (UIAS). Analysis of variance was performed to compare the differences in scores among nursing students based on demographic or educational background. Pearson's correlation coefficient or χ2 was used to examine the relationships between variables and multivariate regression analyses were performed to identify the predictors of attitude toward urinary incontinence. RESULTS: Urinary incontinence knowledge was moderate (mean 22.0/30, SD 4.4) and attitudes about urinary incontinence were positive (mean 41.6/60, SD 4.5). There was a significant correlation between attitudes and knowledge (r = 0.175, P = .001), institution at which the students received training (χ2 = 161.790, P = .000), and the experience of having taken a course that included instruction about urinary incontinence (χ2 = 37.707, P = .014). Regression analysis revealed that knowledge and institution were predictors of attitudes. Participants reported high level of interest in learning more about urinary incontinence (71.2%). CONCLUSIONS: Nursing students residing in Hong Kong have a moderate level of knowledge and positive attitude toward urinary incontinence. This study suggests that educational institution and specific instruction about urinary incontinence play key roles in developing positive attitudes toward caring for patients with urinary incontinence.
