Sleep disorders in Chinese patients with Parkinson's disease: validation study of a Chinese version of Parkinson's disease sleep scale.
To evaluate the Chinese version of the Parkinson's disease sleep scale (PDSS) as an instrument for measuring sleep disorders in Chinese patients with Parkinson's disease (PD). The objective of the present study was to carry out a metric analysis of a Chinese version of PDSS using a cross-sectional study of 126 patients with PD who participated in the study. Usual measures for PD patients including the Pittsburgh sleep quality index (PSQI), the Epworth sleepiness scale (ESS), the Geriatric Depression Scale (GDS), and the Hamilton Anxiety Scale (HAMA) were applied by neurologists. The intra-class correlation coefficient was 0.880, and test-retest reliability for total PDSS score was 0.914. The Mean total PDSS score was 118.38+/-26.07. There was a significant correlation between the PDSS and PSQI, between the PDSS and ESS, between the PDSS and GDS, between the PDSS and HAMA, between the PDSS and the disease durations, and between the PDSS and the LDE, respectively. The Chinese version of PDSS met some basic standards required for sleep disorders measures. It could lead to better understanding the sleep disorders of PD of China in future studies.
