Background And Purpose:
Evidence-based practice (EBP) is essential to optimal health care outcomes. Interventions to improve use of evidence depend on accurate assessments from reliable, valid, and user-friendly tools. This study reports psychometric analyses from a modified version of a widely used EBP questionnaire, the information literacy for nursing practice (ILNP).
Methods:
After content validity assessments by nurse researchers, a convenience sample of 2,439 nurses completed the revised 23-item questionnaire. We examined internal consistency and used factor analyses to assess the factor structure.
Results:
A modified 4-factor model demonstrated adequate fit to the data. Cronbach's alpha was .80-.92 for the subscales.
Conclusions:
The shortened ILNP (renamed Healthcare EBP Assessment Tool or HEAT) demonstrated adequate content validity, construct validity, and reliability.
