Reliability and Validity of the Chinese Version of the Ventilator-Associated Pneumonia Prevention Knowledge and Attitudes Scale: A Short Research Report.

Ventilator-associated pneumonia (VAP) remains a prevalent and costly healthcare-associated infection in intensive care units (ICUs). This study aimed to translate the Ventilator-Associated Pneumonia Prevention Knowledge and Attitudes Scale (VAPPKAS), conduct cross-cultural adaptation and test its psychometric properties. A cross-sectional survey was performed, enrolling 322 ICU nurses from one tertiary hospital in Jiangxi Province. The Chinese VAPPKAS consists of two dimensions containing 15 items. The Cronbach's α coefficient was 0.937, split-half reliability was 0.928, and test-retest reliability was 0.907 (95% CI: 0.887-0.924). The item-level content validity index (I-CVI) ranged from 0.867 to 1.000, and the average scale-level content validity index (S-CVI/Ave) reached 0.906. Exploratory factor analysis (EFA) extracted two factors that jointly explained 76.382% of the total variance. Confirmatory factor analysis (CFA) yielded satisfactory model fit indices: χ2/df = 2.326, RMSEA = 0.052, SRMR = 0.026, NFI = 0.927, TLI = 0.918, CFI = 0.922, GFI = 0.903. The Chinese version of the VAPPKAS demonstrates excellent reliability and validity.
