抄録	Objective: This study aimed to develop a Japanese version of the New Freezing of Gait Questionnaire (NFOG-Q) and investigate its validity and reliability. Methods: After translating the NFOG-Q according to a standardised protocol, 56 patients with Parkinson’s disease (PD) were administered it. Additionally, the MDS-UPDRS parts II and III, Hoehn and Yahr (H&Y) stage, and number of falls over 1 month were evaluated. Spearman’s correlation coefficients (rho) were used to determine construct validity, and Cronbach’s alpha (α) was used to examine reliability. Results: The interquartile range of the NFOG-Q scores was 10.0–25.3 (range 0–29). The NFOG-Q scores were strongly correlated with the MDS-UPDRS part II, items 2.12 (walking and balance), 2.13 (freezing), 3.11 (freezing of gait), and 3.12 (postural stability) and the postural instability and gait difficulty score (rho = 0.515–0.669), but only moderately related to the MDS-UPDRS item 3.10 (gait), number of falls, disease duration, H&Y stage, and time of the Timed Up-and-Go test (rho = 0.319–0.434). No significant correlations were observed between age and the time of the 10-m walk test. The internal consistency was excellent (α = 0.96). Conclusions: The Japanese version of the NFOG-Q is a valid and reliable tool for assessing the severity of freezing in patients with PD.
