Sleep disturbances and nocturnal disabilities are common in Parkinson's Disease (PD). The PD sleep scale, second version (PDSS-2), has been proposed as a helpful tool for measuring sleep disorders in PD. We aimed to validate the Italian version of the PDSS-2. One hundred and twenty-three consecutive PD outpatients (76 males) were evaluated by means of PDSS-2, Epworth Sleepiness Scale, Hamilton Depression Rating Scale, Parkinson's Disease Quality of Life Questionnaire (self-administered scales), Unified Parkinson's Disease Rating (motor section) and Hoehn and Yahr Scales, and Mini Mental State Examination. PDSS-2 internal consistency was satisfactory (Cronbach's α: 0.77) with significant item to total score correlation and high intra-class correlation coefficient for test-retest reliability (0.943). Total PDSS-2 score was correlated with the scores on all other clinical scales. The factor analysis identified five factors, related to five areas of nocturnal disturbances, similarly as the original PDSS-2. The five factors mainly reflected: (1) nocturnal movement-related problems, (2) quality of sleep, (3) dreaming distress, (4) fragmentation of sleep and (5) insomnia symptoms. The PDSS-2 scale has confirmed its usefulness in evaluating sleep problems in Italian PD patients.
睡眠障碍和夜间功能障碍在帕金森病（PD）中很常见。帕金森病睡眠量表第二版（PDSS - 2）已被提议作为测量帕金森病睡眠障碍的有用工具。我们旨在验证PDSS - 2的意大利语版本。通过PDSS - 2、爱泼沃斯思睡量表、汉密尔顿抑郁量表、帕金森病生活质量问卷（自评量表）、统一帕金森病评定量表（运动部分）、霍恩和亚尔分级量表以及简易精神状态检查表，对123名连续的帕金森病门诊患者（76名男性）进行了评估。PDSS - 2的内部一致性令人满意（克朗巴哈α系数：0.77），各项目与总分的相关性显著，重测信度的组内相关系数较高（0.943）。PDSS - 2总分与所有其他临床量表的得分相关。因子分析确定了五个因子，与夜间干扰的五个领域相关，与原始的PDSS - 2类似。这五个因子主要反映了：（1）夜间运动相关问题，（2）睡眠质量，（3）梦境困扰，（4）睡眠碎片化和（5）失眠症状。PDSS - 2量表已证实其在评估意大利帕金森病患者睡眠问题方面的有用性。
