Two hundred and one adult patients (aged over 18 years old) with sleep disorders were recruited. All \ufb01lled out the 11-item Chinese version of GSAQ. The translated version was tested by exploratory factor analysis (EFA), confirmatory factor analysis (CFA), criterion validity, Cronbach\u2019s \u03b1 and spilt-half reliability.
