BACKGROUND AND AIMS
The aim of the present study was to measure the test-retest validity of Parkinson's Disease Sleep Scale 2nd version (PDSS-2) on PD patients with stable medication and motor symptoms over the period of 4 weeks.
METHODS
The subject population consisted of 92 PD patients. Besides PDSS-2, Unified PD rating scale, Montgomery-Asberg Depression Rating Scale and EQ-5D were assessed at baseline and 4 weeks later.
RESULTS
The total score of PDSS-2 decreased from 19.06 ± 10.78 points to 18.00 ± 9.34 points (p > 0.05). For the total score of PDSS-2 the Intra-class and Lin's Concordance Correlation Coefficients were 0.782 and 0.799. The average difference between the baseline and follow-up total PDSS-2 scores was -1.06 points with the 95% confidence interval of -7.96 and +5.84 points.
CONCLUSIONS
Our data supports that the items and the total score of PDSS-2 have acceptable test-retest reliability over a four week period on patients with stable PD symptoms and pharmacological therapy.
背景与目的
本研究旨在测量帕金森病睡眠量表 2 版（PDSS-2）在药物稳定且运动症状稳定的帕金森病患者中，4 周内的重测信度。
方法
研究对象为 92 名帕金森病患者。在基线和 4 周后，评估 PDSS-2、统一帕金森病评定量表、蒙哥马利-阿斯伯格抑郁评定量表和 EQ-5D。
结果
PDSS-2 的总分从 19.06 ± 10.78 分降至 18.00 ± 9.34 分（p > 0.05）。PDSS-2 总分的组内相关系数和林氏一致性相关系数分别为 0.782 和 0.799。PDSS-2 总分的基线和随访之间的平均差值为-1.06 分，95%置信区间为-7.96 至+5.84 分。
结论
我们的数据支持在药物稳定且运动症状稳定的帕金森病患者中，PDSS-2 的条目和总分在 4 周内具有可接受的重测信度。
