Internal consistency is expressed by Cronbach's α and interrater reliability by ICC. ICC values were calculated using a two‐way random model with absolute agreement.
Abbreviations: α, alpha; CI, confidence interval; ICC, intraclass correlation coefficient; NA, not applicable; UHDRS, Unified Huntington's Disease Rating Scale; UHDRS‐FAP, Unified Huntington's Disease Rating Scale‐For Advanced Patients.
