Abstract
Aims & objectives: This study aims to evaluate the psychometric performance of a new instrument to assess catheter associated urinary tract infection (CAUTI) prevention knowledge.
Background: Catheterisation of the urinary tract is one of the most frequent clinical procedures, often resulting in CAUTI and causing unnecessary burdens to individuals and healthcare services. Interventions to decrease the risk of CAUTI emphasise healthcare workers' knowledge of CAUTI prevention. An instrument is required to assess the level of healthcare workers' CAUTI prevention knowledge as a systematic review established that existing CAUTI prevention knowledge measurement instruments are of inadequate psychometric quality and cannot be recommended for such purposes.
Design: A registered cross-sectional validity study of a psychometric instrument.
Methods: The newly developed instrument was administered online to N=xxx healthcare workers and students. We conducted an item analysis; confirmatory and exploratory factor analyses evaluating the structural validity; and known-groups hypotheses testing to evaluate construct validity to evaluate the psychometric performance.
Results: Results are reported for each of the psychometric analyses (all analyses in R). The results suggested that [summary of dimensionality assessment]. The known-groups tests showed [summary of known-groups test]. After summarising the evidence, xx items were removed from the pool and xx items were suggested to be used in the future as an instrument.
Conclusion: The study contributes to the literature by bridging the existing gap in valid and reliable CAUTI prevention knowledge measurement with a psychometric evaluation of an extensive pool of knowledge items derived from a systematic literature review, guidelines, and a Delphi study involving international experts.
Relevance to clinical practice: The instrument will help researchers, professional groups, and organisations design and effectively evaluate CAUTI prevention knowledge interventions.
