Validation of short version of evidence-based practice instruments among nurses in clinical practice: Evidence-based practice beliefs, implementation, and organizational culture

Abstract

Objective: The objective of the study is to validate the short version of evidence-based practice (EBP) instruments among nurses in clinical practice. Methods: An institutional-based cross-sectional research design was used and a stratified sampling technique to select 285 nurse clinicians. The study utilized a structured questionnaire comprising of demographic data from the participants and three validated scales: the shortened versions of the EBP Beliefs Scale, the EBP Implementation Scale, and the Organizational Culture and Readiness for System-Wide Integration of Evidence-Based Practice (OCRSIEP) survey. With the use of descriptive statistics, the data were analyzed and presented in frequencies and percentages, while inter-item correlation coefficient (ICC) and the Kaiser-Meyer–Olkin measure of sampling adequacy were used to confirm the validity of using factor analysis. Results: Findings revealed the mean scores of the EBP Beliefs Scale ranged from 1.50 to 1.61, EBP Implementation Scale ranged from 1.84 to 1.94, and the OCRSIEP Scale ranged from 1.93 to 2.19. All the three shortened scales accordingly had good internal reliability, 29.30 ± 9.93 out of 80 for the EBP Beliefs Scale, 19.56 ± 7.37 out of 72 for the EBP Implementation Scale, and 66.32 ± 20.35 out of 125 for the OCRSIEP Scale. Conclusion: This study has generated a valid Short Version of EBP reliable instrument that is psychometrically robust that can be used by nurses and clinicians to evaluate EBP in clinical settings since the results presented as a whole confirmed the high reliability and factorial validity.
