Abstract

Background and Purpose: Evidence-based practice can improve quality of care and patient and system outcomes. Healthcare professionals need certain research competencies to achieve evidence-based practice. We aimed to evaluate the psychometric properties of the self-reported 19-item Research Competencies Assessment Instrument for Nurses (RCAIN) with Greek. Methods: This cross-sectional study included in total, 520 respondents (within 33 health organizations) who completed the 5-point Likert-type RCAIN as well as the 8-item “Research Utilization by Nurses” that was used to assess construct validity. Expert scholars translated both survey questionnaires into the Greek language. A baseline one-factor model was compared against three-factor model (i.e., knowledge, skills, and application of knowledge and skills) that were developed based on the hypothetical design of the instrument. Results: Participants were females (86.4%) 50 years old or younger (91%). The RCAIN had a Cronbach's alpha coefficient of 0.937 and intraclass correlation coefficient of 0.440 (95% CI 0.403 to 0.480, p < .001). Confirmatory factor analysis revealed a 3-factor solution (i.e., knowledge, skills, application of knowledge & skills). Fit indices for the three-factor model were statistically superior when compared with the baseline model. Reliability and validity of each subscale were acceptable. Further assessment of construct validity using hypothesis testing indicated that there is a statistically significant difference in research utilization by knowledgeable or not participants. Specifically, the effect size between knowledge synthesis and instrumental research use was eta squared = 0.020, meaning that approximately 2.0% of the variance in instrumental research use scores can be explained by knowledge in methods of knowledge synthesis. The predictive validity, based on correlations between the two instruments, showed that increasing levels of instrumental research use were associated with an increasingly positive and statistically significant pattern of correlations. Conclusions: The RCAIN survey is a psychometrically sound tool for nurses. Providers, educators, and health administrators may use it for professional development and improvement of individual research competencies.
