Development and Validation of a Questionnaire to Measure ICU Nurses' Knowledge, Attitudes, and Practices Related to Central Line Bloodstream Infection Practices

Currently, there is no instrument available to assess intensive care unit (ICU) nurses' knowledge, attitudes, and practices (KAP) of central line-associated bloodstream infection (CLABSI) prevention practices.To develop and validate a CLABSI questionnaire to measure ICU nurses' KAP (CLABSI-KAP-Q).Data were collected from 255 nurses at 4 hospitals in Gansu Province, China. Questions on the CLABSI-KAP-Q were generated through a review of the literature, interviews with nurses, and multiple rounds of content validity evaluation by experts. The validity and reliability of the CLABSI-KAP-Q were assessed with exploratory factor analysis, confirmatory factor analysis, internal consistency, and correlation coefficients.The final version of the CLABSI-KAP-Q consisted of 32 items. The reliability was represented by a Cronbach α of 0.946, while the test-retest reliability was 0.945. The overall content validity was 0.95.The CLABSI-KAP-Q is shown to be valid and reliable and recommended for use in clinical practice.
