A Turkish Version of the Critical-Care Pain Observation Tool: Reliability and Validity Assessment
The study aim was to evaluate the validity and reliability of the Critical-Care Pain Observation Tool in critically ill patients.Design:
A repeated measures design was used for the study.Methods:
A convenience sample of 66 patients who had undergone open-heart surgery in the cardiovascular surgery intensive care unit in Ordu, Turkey, was recruited for the study. The patients were evaluated by using the Critical-Care Pain Observation Tool at rest, during a nociceptive procedure (suctioning), and 20 minutes after the procedure while they were conscious and intubated after surgery.Finding:
The Turkish version of the Critical-Care Pain Observation Tool has shown statistically acceptable levels of validity and reliability. Inter-rater reliability was supported by moderate-to-high–weighted κ coefficients (weighted κ coefficient = 0.55 to 1.00). For concurrent validity, significant associations were found between the scores on the Critical-Care Pain Observation Tool and the Behavioral Pain Scale scores. Discriminant validity was also supported by higher scores during suctioning (a nociceptive procedure) versus non-nociceptive procedures. The internal consistency of the Critical-Care Pain Observation Tool was 0.72 during a nociceptive procedure and 0.71 during a non-nociceptive procedure.Conclusions:
The validity and reliability of the Turkish version of the Critical-Care Pain Observation Tool was determined to be acceptable for pain assessment in critical care, especially for patients who cannot communicate verbally.
