[Validation of an instrument for assessing the ability of blood pressure measurement].

This study aimed to validate an instrument for evaluation the ability of nursing students to measure the blood pressure. It is a methodological study, developed with 27 nurses, teachers of semiology and/or semiotic disciplines, with at least 1 year of experience in disciplines, which acted as judges of the study. It was accomplished in two steps: first, a review of the literature to build the checklist instrument and subsequent submission for content validation by applying the Kappa, accepting the value > 0.61 (good level); and second, it was accomplished a Content Validity Index (CVI) > 0.75. Based on the literature review, 28 items were included in the checklist, with all of them showing Kappa index and CVI accepted for content validity, and nine of those items needed changes. The instrument can be considered valid in its content, with all its items being considered appropriate separately, as well as globally.
