The pre-final version of the instrument was evaluated by 36 participants in renal replacement therapy and seven specialists in nephrology Results: For each item, the Item Content Validity Index -I-CVI >= 0.85 was achieved; and 0.99 for the mean Scale Content Validity Index -S-CVI/Ave in conceptual and content equivalence. The binomial test showed a p-value >= 0.05 for all items; and the Kappa Coefficient of Agreement was 0.9. Conclusion: The adapted instrument was found to be clear by the participants, and the content was validated by the experts.
