Aims : To culturally adapt and translate the Evidence‐Based Practice Belief Scale (EBP‐B) and the Evidence‐Based Practice Implementation Scale (EBP‐I), explore the psychometric properties of their validated German versions and compare results with those of the original scales. Design : Cross‐sectional descriptive study. Method : The study was conducted on a sample of 131 Registered Nurses in a Swiss German hospital. Internal consistency was rated using Cronbach's alpha. Principal component analysis using varimax rotation was used to determine construct validity. The study was undertaken in accordance with the STROBE‐checklist in Appendix S1. Results : German versions of the EBP‐B and EBP‐I showed good reliability. Their Cronbach alphas showed lower values than those of the original scales. Principal component analysis showed medium‐to‐high factor loading. Principal component analyses using varimax rotations of the EBP‐B's 16 items and the EBP‐I's 17 items resulted in four‐factor and five‐factor solutions, respectively.
