The Chinese version of the Global Sleep Assessment Questionnaire demonstrated acceptable reliability and validity for evaluating sleep disorders in adult patients, with four factors explaining 68.89% of total variance and ROC analysis yielding AUC > 0.8.
Each item of the 11-item Chinese version of GSAQ was significantly correlated with the total score.
Exploratory factor analysis extracted four factors from the Chinese version of GSAQ that explained 68.89% of the total variance.
The Chinese version of GSAQ demonstrated acceptable internal consistency reliability.
ROC analysis demonstrated good predictive ability of the Chinese GSAQ with AUC greater than 0.8 for sleep disorder categories.
The Chinese GSAQ showed significant positive correlations with established criterion measures for obstructive sleep apnea, insomnia, and REM sleep behavior disorder.
There was no statistically significant correlation between the total GSAQ score and the International Restless Legs Syndrome (iRLS) rating scale.
The GSAQ was translated into Chinese following standardized scale translation procedures and validated in a sample of 201 adult patients with sleep disorders.
This research suggests that the Global Sleep Assessment Questionnaire (GSAQ), a tool designed to screen for multiple types of sleep disorders in a single questionnaire, can be reliably used in Chinese-speaking adult patients after being translated into Chinese. The study recruited 201 adult patients with sleep disorders and put the translated questionnaire through a series of statistical tests to confirm it measures what it is supposed to measure and produces consistent results. The questionnaire was found to organize into four groups of questions covering sleep apnea, insomnia, restless legs syndrome, and parasomnias (abnormal behaviors during sleep), and these four groupings together explained about 69% of the variation in patient responses. The Chinese GSAQ showed good agreement with other established sleep measurement tools — for example, it correlated meaningfully with polysomnography-derived apnea scores, an insomnia severity index, and a REM sleep behavior disorder screening questionnaire. The researchers also identified specific score cutoffs that could help clinicians decide when a patient's responses suggest a clinically significant sleep problem. One notable exception was that the total GSAQ score did not significantly correlate with the restless legs syndrome severity scale, which may warrant further investigation. This research suggests that Chinese-speaking clinicians and researchers now have a validated, multi-disorder sleep screening tool available to them. Because the GSAQ covers several types of sleep disorders in a single short questionnaire, it could be practically useful in busy clinical settings where time for lengthy assessments is limited, potentially helping identify patients who need further specialized evaluation for conditions like sleep apnea, insomnia, or parasomnias.
