    ContextThe psychometric properties of the Critical-Care Pain Observation Tool (CPOT) need to be tested in general intensive care unit patient populations in China.ObjectivesTo further evaluate the psychometric properties of the CPOT and provide a pain assessment method for Chinese critically ill ventilated adults by validating a translation of the CPOT.MethodsA total of 63 conscious ventilated Chinese adults were repeatedly assessed by two independent raters using the CPOT at rest as well as before and during the two procedures: 1) nociceptive procedure (turning) and 2) non-nociceptive procedure (taking noninvasive blood pressure). A total of 12 assessments were included.ResultsThe principal component factor analysis revealed that the domain structure of the CPOT was acceptable. Cronbach's α coefficient as a measure for the internal consistency ranged from 0.57 to 0.86; intraclass correlation coefficients as a measure for inter-rater reliability ranged from 0.80 to 0.91; Spearman nonparametric coefficients as a measure for test-retest reliability ranged from 0.81 to 0.93. The CPOT total score was significantly higher during the nociceptive procedure, indicating that its discriminant validity was good. Self-reported pain was obtained as the gold standard; the receiver operating characteristic curve analysis determined the best cutoff value of the CPOT (>2) with the specificity (73.3-81.8%) and sensitivity (80.8-89.4%) as well as the area under the curve (range 0.849-0.902).ConclusionThe CPOT has good psychometric properties and can be used as a reliable and valid instrument for pain assessment in Chinese critically ill ventilated adults.Copyright © 2014 American Academy of Hospice and Palliative Medicine.
