Objective: The primary aim was translation to thai and cognitive debriefing of the thai version of the hfs score in patients with hfs. The secondary aim was testing the psychometric properties of the translated score.

Background: Hemifacial spasm (hfs) affects patients’ function and health-related quality of life (hrqol). The hfs score questionnaire is used to assess the therapeutic effect of botulinum neurotoxin a (bont-a) therapy in both of the clinical (hfs-clinical) and hrqol aspects (hfs-subjective).

Method: A single-centered prospective, observational study was conducted from september 2022 to december 2022. One hundred sixty-one hfs patients treated with BoNT-A were recruited. Before start the BoNT-A treatment, all eligible participants were interviewed using thai version of the hfs score. Then, the translated score was used to assess all participants again on the third week (+1 week) after the BoNT-A treatment.

Results: One hundred fifty-seven patients [mean age=63.6 y (range 31.0, 89.0); female=72.6%] completed the study. Regarding the translated score, cronbach’s alpha showed acceptable internal consistency (α=0.90). All hfs-clinical and hfs-subjective items showed responsiveness to change between baseline and follow-up (all p<0.05).

Conclusion: The Thai version of the HFS score showed acceptable psychometric properties for use as a patient-reported HFS HRQoL instrument.
