Background:
Nurses' knowledge, attitudes, and practices (KAP) regarding external ventricular drainage (EVD) significantly impact patient care quality.
Purpose:
The study aimed to develop and validate a suitable questionnaire for assessing neurosurgical nurses' KAP regarding EVD care.
Methods:
This study developed a questionnaire from a literature review, semi-structured interviews, team discussions, and 2 Delphi rounds, then administered it to 841 neurosurgical nurses to assess its psychometric properties, including content validity, structural validity, and reliability.
Results:
The final 40-item questionnaire had a Cronbach's α of 0.871, split-half reliability of 0.820, test-retest reliability of 0.853, with the content validity index ranging from 0.861 to 1.000. Exploratory factor analysis revealed 11 factors, collectively accounting for 64.17% of the total variance.
Conclusions:
The developed questionnaire can serve as a useful tool for assessing neurosurgical nurses' knowledge, attitudes, and practices regarding EVD care.
