Validation Study of the Thai ID Pain Scale
Kitisomprayoonkul W 
Objective: To translate the ID Pain scale into Thai and validate this scale.
Material and Method: The 6-item ID Pain scale was translated into Thai. The final version was tested in 100 patients. Sensitivity, specificity, and predictive validity were calculated.
Results: Twenty-four patients were neuropathic, 49 were nociceptive and 27 were mixed pain. Forty-six patients have chronic pain. Seventy-five were female. Sensitivity and specificity for diagnosis of neuropathic pain were 83% and 80%. The predictive validity using area under the ROC curve of the neuropathic, mixed and nociceptive pain groups were 0.890 (95% CI 0.824-0.955), 0.587 (95% CI 0.464-0.709) and 0.147 (95% CI 0.071-0.224), respectively.
Conclusion: The Thai ID Pain scale is brief, convenient to complete and had good predictive validity for screening of neuropathic pain. Prediction validity of mixed pain is moderate and of nociceptive pain is low.
Keywords: Neuropathic pain, Diagnostic tools, Psychometric assessment
