Reliability and validity of the Thai version of the Dry Eye Questionnaire 5 (T-DEQ-5)
Main Article Content
Abstract
Purpose: To evaluate reliability and validity of the Thai translation of DEQ-5 questionnaire.
Setting/Venue: Online survey, Ophthalmology Department at Thammasat Hospital, Thailand
Method: Translation of the survey from English to Thai was done by ophthalmologists and linguists using focus group analysis. Content validity of the translated survey was assessed by 10 examiners who are fluent in both English and Thai. The examiners are 2 corneal and refractive surgery specialists, 2 general ophthalmologists, 2 general practitioners, 2 health care personnel in the ophthalmology department and 2 language experts. Validity indexes, Item Objective Congruence (IOC) and Content Validity Index (CVI) were collected. Then, 291 people completed the translated survey through an online database to calculate the reliability coefficient.
Results: T-DEQ-5 generated a Cronbach’s Alpha value, mean IOC, mean CVI, and S-CVI of 0.86, 0.99, 0.90, and 0.88, respectively.
Conclusion: The translated questionnaire has high validity and reliability and may be used in the clinical setting for diagnosis of DED.
