Abstract
Background
The 25-item Central Sensitisation Inventory (CSI-25) is a patient-reported instrument used to screen patients at risk of central sensitisation, a pathophysiological mechanism implicated in many chronic pain syndromes.
Aims
To adapt and validate a Chinese version of the CSI-25 in the Chinese population.
Methods
The Chinese CSI-25 was developed by the translation of the original English version, back translation, cultural adaptation and revision using the Delphi method. The Chinese CSI-25 was administered to 237 patients with chronic pain and 55 healthy controls. Structural validity (confirmatory factor analysis), construct validity (correlations with other instruments), test-retest reliability and internal consistency were evaluated.
Results
Confirmatory factor analysis extracted four main factors ('physical symptoms', 'emotional distress', 'headache/jaw symptoms' and 'urological symptoms'). The Chinese CSI-25 score was positively correlated with the Pain Catastrophic Scale (PCS) total score (r=0.709), PCS subscale scores (r=0.630-0.695), Brief Pain Inventory (BPI) mean item score (r=0.773), BPI total score (r=0.773) and the number of painful sites (r=0.636). The Chinese CSI-25 had excellent test-retest reliability (intragroup correlation coefficient=0.975) and good internal consistency (Cronbach's α=0.930 in the overall population and 0.882 in the chronic pain population).
Conclusions
The Chinese CSI-25 had excellent test-retest reliability and satisfactory structural validity and construct validity. This instrument could potentially be used in China as a self-report questionnaire in both clinical practice and research settings.
