Background: Common pain assessment tools might not be the suitable tools to measure ventilated, critically ill patients' pain. The Behavioral Pain Scale measures observable behavior indicative of pain experienced by mechanically ventilated patients. Objective: This study was conducted to generate a Chinese-language version of the Behavioral Pain Scale and to test its psychometric properties. Design: This study was a prospective psychometric study. Settings/participants: Seventy patients were recruited from two intensive care units in a medical center. Methods: After instrument translation, psychometric testing which included inter-rater reliability, test-retest reliability, and construct validity was conducted. The construct validity was tested using criterion and discriminant validation strategies. A receiver-operating characteristic curve analysis was conducted to evaluate the ability of the translated tool to correctly detect pain. Measurement of body temperature and endotracheal suctioning were, respectively, selected as the non-painful and painful procedures. Two research nurses observed patients' pain-related behaviors when they were at rest and before/during the non-painful/painful procedures. Results: The Chinese translation captured the content of the original tool with appropriate adaptation to the cultural context. The inter-rater and test-retest reliabilities were confirmed by good Pearson correlations (r=50-1.00, p
