Background: Evidence-based practice (EBP) is essential for ensuring healthcare quality, patient safety, and effective clinical decision-making. As nurses and physicians play a key role in implementing EBP, assessing their attitudes toward it is important. Although tools exist to measure nurses’ attitudes in Türkiye, no scale currently evaluates both nurses and physicians.

Aim: This study aimed to evaluate the validity and reliability of the Evidence-Based Practice Attitude Scale-36 (EBPAS-36), originally developed by Rye et al., for adaptation into the Turkish context.

Methods: Data were collected from 205 nurses and physicians working in the surgical clinics of two hospitals in Izmir between October 2019 and December 2021. The EBPAS-36 and an 18-item descriptive questionnaire developed by the researcher were used. Statistical analyses included means, percentages, standard deviations, and significance testing at the 0.05 level. Validity was assessed through linguistic, content, construct, and face validity, while reliability was evaluated using test-retest analysis and Cronbach’s alpha.

Results: Of the participants, 71.2% were female, with a mean age of 32.15±7.88 years (range: 22-58). Nurses comprised 76.1% of the sample, while physicians made up 23.9%. The content validity index of the EBPAS-36 was 0.68, exceeding the minimum acceptable threshold. Construct validity analysis yielded a Kaiser-Meyer-Olkin (KMO) value of 0.80. Confirmatory factor analysis supported a ten-factor structure for the Turkish version, which differed from the original scale. The 10 sub-dimensions explained 58.714% of the total variance. The scale demonstrated strong reliability, with a Cronbach's alpha coefficient of 0.828 and a McDonald's omega coefficient of 0.859.

Conclusion: The analyses indicated that the EBPAS-36 possesses linguistic and content validity, structural integrity, face validity, Cronbach's alpha internal consistency, and test-retest reliability. Based on these findings, the scale is valid and reliable for healthcare professionals, particularly physicians and nurses, within the Turkish cultural context.
