Psychometric testing of the continence and mobility in older adults knowledge quiz

Abstract

AbstractWhat are the psychometric properties of the Continence and Mobility in Older Adults Knowledge Quiz? Our previous research revealed gaps in practicing and student nurses' knowledge of mobility and continence in older people. To address this gap, we developed a self‐directed e‐learning module on continence and mobility to enhance student nurses knowledge. The module provided education about continence, mobility, and the links between them. Since we were unable to locate a continence and mobility measure that captured both lower urinary track symptoms and elements of mobility, we developed a continence and mobility knowledge quiz. For researchers and educators to be able to use this quiz with confidence, psychometric testing of our continence and mobility knowledge quiz was required. When caring for older people, two geriatric challenges—continence and mobility—are often linked and viewed as indicators of frailty. Functional changes related to continence and/or mobility can indicate an acute illness in older persons and, if left untreated, can result in permanent changes managing continence needs. Continence care is often viewed negatively and is not prioritized by nurses. We employed stages in development of the Continence and Mobility Knowledge Quiz. In stage one, we developed 18 item true/false items from the literature with the guidance of a continence expert. In stage two, we tested the Quiz with nursing students from three universities in Canada. In stage three, (the current stage) we assessed the validity of the scale using a factor analysis and a reliability analysis (via standardized Cronbach's alpha). From our sample of 420, factor analysis indicated a two‐factor model (as suggested by Kaiser's rule), explained 22% of the variation in responses to the assessment items. We recommend removing item 7 as it does not contribute to the internal consistency of the tool. Cronbach's alpha after removing 7 is 0.65, indicating satisfactory reliability. To our knowledge, this is the first validated tool for measuring nurse knowledge about continence and mobility that addresses both a range of lower urinary tract symptoms and elements of mobility in older adults.
