Between 1 and 15 of December 2016, the developed EBP-questionnaire was administered to a cohort of resident/specialist physicians (n=32) to assess the face, content and construct validity as well as its applicability. Results: The final instrument contained 23 multiple choice questions (the responder can chose one or more than one answer), one question with dichotomial answer (yeso) and 15 open questions. An average of the Likert scores equal with 4.5 (out of 5) and a Cronbach's score of 0.993 were obtained for the whole questionnaire. 62.5% (n=20) of the participants considered this questionnaire being useful and necessary to be expand through Romanian physicians.
