Reliability and Validity of the Italian Translation of the Updated Version of the Pressure Ulcer Knowledge Assessment Tool ( PUKAT 2.0)

The study aimed to translate the PUKAT 2.0 tool from English to Italian. This was an adaptation and validation study; the validity of the Italian version was determined through content validity, item validity and construct validity. The reliability of the instrument was assessed by conducting a test-retest analysis on a sample of 62 nurses. The I-CVI indices were above the threshold of 0.78 for 91% of the questions, and according to the S-CVI index, 96% of the evaluators agreed that the questionnaire was highly relevant. The overall values for item difficulty were good, with two items being too difficult and none being too easy. The item discriminant index was overall good and reasonable, low for four items. The overall ICC was poor to moderate with a value of 0.48 (95% CI 0.26-0.65). The instrument has proven to be a good starting point although not yet completely reliable, as it clearly requires more basic preparation on the part of the staff, further modifications regarding the reliability and clarity of the questions and more training of the nursing staff if it is to be used in the Italian context.
