Purpose: The purpose of this methodological study was to examine the reliability and validity of a translated Korean version of the Critical Care Pain Observation Tool (CPOT) developed for assessment of pain in critically ill nonverbal patients. Methods: A cross-sectional study design was used. Data were collected from a convenience sample of 202 critically ill patients admitted to a university hospital. Upon establishment of content and translation equivalence between the English and Korean version of CPOT, psychometric properties were evaluated. Results: The interrater reliability was found to be acceptable with the weighted kappa coefficients of .81-.88. Significant high correlations between the CPOT and the Checklist of Nonverbal Pain Indicators were found indicating good concurrent validity (r=.72-.83, p<.001). Data showed the area under the ROC curve of 0.86 with a cut-off point of 1, which resulted in 76.9% sensitivity and 88.6% specificity. The mean score of CPOT during suctioning was significantly different from that of before (t= -14.16, p<.001) or 20 minutes after suctioning (t=16.31, p<.001). Conclusion: Results of this study suggest that the CPOT can be used as a reliable and valid measure to assess pain in critically ill nonverbal patients.

Patients unable to speak are at higher risk for untreated pain. Use of valid behavioral and physiologic measures for pain is highly recommended for uncommunicative patients. This study was performed to compare the reliability and validity of NVPS-K and CPOT-K for pain assessment of nonverbal patients. This study was conducted from July to November 2011. A total of 29 nonverbal adult patients admitted to a university hospital intensive care unit participated in this study. Interrater reliability of the NVPS-K and CPOT-K had intermediate to high intraclass correlation coefficients (NVPS-K 0.680 ~ 0.921, CPOT-K 0.710 ~ 0.896). Discriminant validity was supported with higher instrument scores during turning and endotracheal suctioning than that of NIBP. For criterion validity, the NVPS-K scores were correlated to the self-reported pain of the patients but not the CPOT-K scores. The areas under the ROC curve for the NVPS-K and CPOT-K were 0.748 and 0.696 with cutoff points of 1 and 2, respectively. Thus, the NVPS-K and CPOT-K had a sensitivity and specificity of 94.7% and 45.0%, and 60.5% and 75.0%, respectively. The NVPS-K and CPOT-K are reliable and valid tools to assess pain in nonverbal patient and thus, are recommended for the assessment of the pain in nonverbal patients.

Purpose: The purpose of this study was to examine the reliability and validity of a Korean version of the Critical Care Pain Observation Tool (CPOT) developed for assessment of pain in critically ill nonverbal patients. Methods: Data were collected from a convenience sample of 30 critically ill patients admitted to a medical ICU in a hospital. The CPOT was tested at before, during and 20 minutes after changing a position and suction. Upon establishment of content and translation equivalence between the English and Korean version of CPOT. Results: The interrater reliability was found to be acceptable with the kappa coefficients of .76-1. The construct validity of the pain scores were increased from 0.43 to 2.5 in changing a position (t=-8.60, p<.001)and 0.1 to 3.23 (t=-9.36, p<.001) in suctioning. The pain scores were decreased from 6.06 to 4.01 in changing a position (t=-10.19, p<.001) and 6.45 to 4.13 (t=-10.39, p<.001) in suctioning. The concurrent validity the correlations between pain scores and physiological indicators, and a increased in Heart rate before and after changing a position (r=.65, p<.001). Conclusion: The CPOT can be used as a reliable and valid measure to assess pain in critically ill nonverbal a medical ICU patients.
