The validity and reliability study of the Turkish version of the evidence based practice evaluation competence questionnaire.

INTRODUCTION: Identifying the competence of nursing students in evidence-based practice in nursing is important in planning education to train nurses to know, apply and improve evidence-based practice.

PURPOSE: To perform a validity and reliability study for the Turkish version of the "Evidence-based Practice Competence of Nursing Students" questionnaire.

DESIGN: This methodological study was conducted with 199 undergraduate nursing students in a university located in eastern Turkey, between April 1 2014 and February 4 2016. Written permission of the authors, relevant institutions and the students' verbal consent were obtained before administering the questionnaire. The Evidence-based Practice Evaluation Competence Questionnaire (EBP-COQ), developed by Ruzafa-Martinez in Spain, was used for data collection. The 5-point Likert-type scale includes 25 items and three subscales.

RESULTS: The opinions of eight experts were consulted to test content validity, and the content validity index was found to be 0.93. In the factor analysis of the scale, the KMO index was 0.856, and Barlett's sphericity test yielded the results, X(2)=2174.93, df=300 and p=0.000. Cronbach's alpha coefficient was found to be 0.826. The scale's goodness of fit index (AGFI) is 0.755, and its ratio of chi-square statistic to degrees-of-freedom was (X2/df) 2.416 (X2=657.364 df=272). Its root mean square error of approximation (RMSEA) was 0.076, its Tucker-Lewwas index (TLI) 0.902, and its comparative fit index (CFI) value was 0.926.

CONCLUSION: It was determined that the Turkish version of the scale is a valid and reliable tool for determining the competence of students in evidence-based practice.
