The present study determined the content validity of an instrument to assess Colombian health institutions physical access. The questionnaire was designed by the authors of the study, based on the Colombian Technical Standard of Accessibility to the Physical Environment 6047 framework. The content validity was carried out by six experts. To the score the content validity, the researchers designed a qualification template, and calculated a content validity index dividing the relevance and pertinence score of each item/question by the number of experts who evaluated the question. Based on methodological recommendations from the literature, items with content validity index ≤ 0.78 were eliminated from the questionnaire or modified in their wording in accordance with the recommendations of the expert reviewers. The content validity index of the scale was found to be excellent (0.95). In total, 2 questions were eliminated due to their low relevance index (≤ 0.78). The final questionnaire has 69 questions. The importance of determining the validity of the scale in the present study, lies in the fact that a firm scientific basis must be constructed to verify whether such an instrument accurately measures reality.
