The Content Validity Index was calculated for each item, considering one with a value equal to or greater than 0.8 as valid. Results: all the actions described in the checklist and in the banner had a Content Validity Index greater than 0.80, with standardization of verbal time and esthetic adjustments in the banner’s layout, as suggested. Conclusions: the checklist and the banner were validated and can be used in clinical practice to facilitate pressure injury preventions in patients in prone position.
