Objective: This study aimed to perform cultural adaptation and evaluate the psychometric properties of the Turkish version of the Evidence-Based Practice Implementation Scale developed by Melnyk et al. Method: This methodological study included 242 nurses from public, university, and private hospitals in a central metropolitan area of Türkiye. Scale adaptation was conducted according to Beaton et al.'s and International Test Commission's six-stage cross-cultural process. Sampling adequacy and the suitability of the data for factor analysis were evaluated using the Kaiser-Meyer-Olkin and Bartlett's tests of sphericity. Construct validity was examined through Exploratory and Confirmatory Factor Analysis. Reliability was determined using Cronbach's Alpha, McDonald's Omega, and item-total correlations. Results: Content validity index values ranged from 0.857 to 1.000 at the item level, and averaged 0.897 at the scale level. The Kaiser-Meyer-Olkin value was 0.950, and Bartlett's test of sphericity was significant (p<0.001). Exploratory factor analysis revealed two factors explaining 71.068% of total variance: "Evidence Integration and Clinical Implementation" (13 items, 45.064% variance) and "Evidence Search and Critical Appraisal" (5 items, 26.004% variance). Factor loadings ranged from 0.715 to 0.944. Confirmatory factor analysis demonstrated acceptable model fit (CMIN/df=3.158; GFI=0.805; CFI=0.870; RMSEA=0.095). Reliability analysis achieved excellent internal consistency; Cronbach's Alpha was 0.967, and McDonald's Omega was 0.983. Reliability coefficients for sub-dimensions were also adequate (alpha=0.883 -0.964; omega =0.922 -0.979). Conclusion: The Turkish version demonstrated strong psychometric properties, providing a valid and reliable tool for assessing evidence-based practice competencies among nurses. The two-factor structure identified in this study revealed that Turkish nurses perceive evidence-based practice skills differently from the original scale. This scale will contribute to evaluating competency development interventions for healthcare organizations and researchers.
