Anxiety disorder is a common non-motor symptom among individuals with Parkinson's disease (PD). At present, there are no specific tools in China for assessing the anxiety level of patients with PD. This study aimed to test the reliability and validity of the Chinese version of the Parkinson Anxiety Scale (C-PAS) in Chinese patients with PD.
A total of 158 patients with PD at one hospital in Nanjing were recruited through convenience sampling. The C-PAS was translated into Chinese using a classic 'forward-backward' translation method. Reliability tests included internal consistency and test-reliability. And in addition to content, structure and criterion-related validity were performed for the validity tests. Criterion-related validity was evaluated with the Hospital Anxiety and Depression Scale-Anxiety Subscale (HADS-A).
Results confirmed the three-factor structure of the original C-PAS with 12 items, including persistent anxiety (5 items), episodic anxiety (4 items) and avoidance behavior (3 items). Significant and positive correlations were obtained between C-PAS and HADS-A (r = 0.82, P<0.01). The Cronbach's α and test-retest reliability of the total scale were 0.89 and 0.84, respectively.
The C-PAS has demonstrated good psychometric properties. Therefore, it can be employed in patients with PD to evaluate the condition of anxiety.
焦虑障碍是帕金森病（PD）患者常见的非运动症状。目前，中国尚无专门用于评估 PD 患者焦虑水平的工具。本研究旨在检验帕金森焦虑量表（C-PAS）中文版在我国 PD 患者中的信度和效度。
采用便利抽样法，选取南京某医院的 158 例 PD 患者。采用经典的“正向-反向”翻译法将 C-PAS 翻译成中文。信度检验包括内部一致性和重测信度。除内容外，还进行了结构和效标关联效度的有效性检验。效标关联效度采用医院焦虑和抑郁量表-焦虑分量表（HADS-A）进行评估。
结果证实了原始 C-PAS 的三因素结构，包括持续性焦虑（5 个项目）、发作性焦虑（4 个项目）和回避行为（3 个项目）。C-PAS 与 HADS-A 之间存在显著的正相关（r=0.82，P<0.01）。总量表的克朗巴赫 α 和重测信度分别为 0.89 和 0.84。
C-PAS 具有良好的心理测量学特性。因此，它可以用于 PD 患者评估焦虑状况。
