As a neurological problem, insomnia or any other sleep disorder were always hardly noticed at the very beginning and even harder to evaluate its consequences at the end. It is essential to identify a valid sleep quality measurement that can be administered widely in the community in order to assist effectively the clinicians on the evaluation of sleep complaints. This study aimed to examine the Pittsburgh Sleep Quality Index (PSQI) on Vietnamese patients with sleep disorders as a general measure of sleep quality. After the forward-backward translation, 122 subjects who had sleep complains were recruited to answer the PSQI, 36 of them filled in the PSQI again 2 weeks later and 86 of them slept over night at the Clinic for a polysomnography. The results showed that overall the Cronbach’s alpha coefficient was 0.789, indicating a good internal consistency. Correlation coefficient was 0.77. Test-retest reliability coefficient was 0.79. Limit of agreement analysis showed an oscillation range from -4.51 to 5.45 of PSQI score, the within-subject coefficient of variation showed that 95% measurements had 27.25% difference compared to the mean score. At cut-off, the sensitivity and specificity were 87.76% and 75%, respectively, with the area under the curve was 0.7583. The present findings support that the Vietnamese Pittsburgh Sleep Quality Index is a reliable tool and can be used for sleep disorder patient or community screening
