Reliability and Validity of the Thai Version – The Standardized Patient Evaluation of Eye Dryness (T-SPEED)
Main Article Content
Abstract
Objective: To evaluate the reliability and validity of the Thai version of The Standardized Patient Evaluation of Eye Dryness questionnaire (T-SPEED)
Design: Cross-sectional descriptive study
Methods: Consisting of four steps
1) Translation of the SPEED questionnaire from English to Thai by a team consisting of an ophthalmologist and a linguist, subsequently reverse-translated from Thai to English by a separate team.
2) Content and construct validity of the translated questionnaire were evaluated by a group of ten experts.
3) Reliability of the translated questionnaire was evaluated from responses of 290 volunteers aged between 18 and 80 years of age, via Google Forms. The period allowed for response was from the 1st August 2022-31st January 2023.
4) Data analysis and evaluation of reliability and validity using item analysis and Cronbach’s Alpha Coefficient.
Results: The indexes of item-objective congruence (IOC) with a mean of 0.93. Content Validity Index scores (CVI) with a mean of 0.98. Item-level Content Validity Index (I-CVI) scores ranged between 0.9 and 1.0 with a total scale-level Content Validity Index (S-CVI) of 0.99. Data suggests this questionnaire has credible validity in both congruence and content. In addition, the data also suggests that the questionnaire has a statistically significant reliability. The group of four questions regarding frequency and regarding severity of eye dryness had a Cronbach Alpha Coefficient value of 0.775 and 0.837 respectively, which may be interpreted as credible.
Conclusion: The Thai-translated version of the SPEED questionnaire has both credible validity and reliability and can be applied to the Thai population and may be particularly beneficial in screening and follow-up of Thai patients with dry eye disease.
