Objective To translate and cross‐culturally adapt the Craniofacial Pain and Disability Inventory (CF‐PDI) into Chinese and, to evaluate measurement properties of the web‐based version of the CF‐PDI. Methods The Chinese version (CF‐PDI/C) was first produced according the guidelines. Then, the web‐based version of CF‐PDI/C (eCF‐PDI/C) was developed by our team and a third‐party survey provider. The eCF‐PDI/C was distributed to patients with painful temporomandibular disorders (TMD) with or without headache to evaluate its psychometric properties. The reliability of the eCF‐PDI/C was detected by internal consistency and test‐retest reliability. The validity of the measure was performed through construct validity and convergent validity. Results A total of 206 patients were recruited. The Cronbach's α value and the intraclass correlation coefficients (ICC) value of the eCF‐PDI/C was .912 and .82, respectively. Following exploratory factor analysis (EFA), three factors were extracted, accounting for 77.153% of the total variation. With regard to the convergent validity, the measure evidenced a good relationship with the global health question. Conclusions The eCF‐PDI/C displays good reliability and validity through rigorous performance tests. This can be recommended for use among patients with painful TMD with or without headache.
