The Freezing of Gait Questionnaire has been translated into several languages. However, it has not been translated into Japanese and its measurement error remains unclear. This study aimed to translate the Freezing of Gait Questionnaire into Japanese, investigate its validity and reliability, and calculate its measurement errors.
Thirty-five patients with Parkinson's disease participated in the study. The Freezing of Gait Questionnaire was translated into Japanese using a forward - backward translation method. Convergent validity was assessed using the Freezing of Gait Questionnaire and Unified Parkinson's Disease Rating Scale Part II(item 14-freezing). The content validity index was calculated using the Freezing of Gait Questionnaire score using correlation coefficients. Internal consistency was measured using Cronbach's alpha. The test - retest reliability was evaluated using the intraclass correlation coefficient(1,1). The Bland - Altman analysis was performed to detect the limits of agreement.
The mean Freezing of Gait Questionnaire score was 9.1 (5.0) points. Convergent validity was 0.655 and content validity index was 0.958. Cronbach's alpha was 0.958, intraclass correlation coefficient(1,1) was 0.951, and the limits of agreement ranged from - 4.9 to3.2 points.
The Japanese version of the Freezing of Gait Questionnaire is a valid and useful tool to evaluate patients with Parkinson's disease.
步态冻结问卷已被翻译成多种语言。然而，它尚未被翻译成日语，其测量误差仍不清楚。本研究旨在将步态冻结问卷翻译成日语，调查其有效性和可靠性，并计算其测量误差。
35名帕金森病患者参与了本研究。采用正向-反向翻译法将步态冻结问卷翻译成日语。使用步态冻结问卷和统一帕金森病评定量表第二部分（项目14-冻结）评估收敛效度。使用相关系数计算内容效度指数。使用Cronbach's alpha测量内部一致性。使用组内相关系数（1,1）评估重测信度。进行Bland-Altman分析以检测一致性界限。
步态冻结问卷平均得分为9.1（5.0）分。收敛效度为0.655，内容效度指数为0.958。Cronbach's alpha为0.958，组内相关系数（1,1）为0.951，一致性界限范围为-4.9至3.2分。
日语版步态冻结问卷是评估帕金森病患者的有效且有用的工具。
