title: Reliability of the Japanese version of the scales for outcomes in Parkinson's disease-autonomic questionnaire.
abstract: OBJECTIVE
  The Scales for Outcomes in Parkinson's Disease-Autonomic (SCOPA-AUT) questionnaire was used to assess autonomic dysfunction in patients with neurological disorders. The aim of this study was to evaluate the reliability of the Japanese version of the SCOPA-AUT.
  
  
  METHODS
  We translated the SCOPA-AUT from English to Japanese. Thirty-one patients with diseases involving autonomic symptoms completed the form twice. The reliability was assessed by Cronbach's coefficient alphas and intraclass correlation coefficients (ICCs).
  
  
  RESULTS
  The average (standard deviation, SD) total scores of the first and second assessments of the SCOPA-AUT were 15.7 (SD, 7.1) and 13.6 (SD, 6.5), respectively. The Cronbach's coefficient alphas were globally high, but the ICCs were moderately high. The valid response rates for the questions about sexual dysfunction were 36.7% in men and 26.6% in women.
  
  
  CONCLUSIONS
  The Japanese version of the SCOPA-AUT had high internal consistency. However, the questions about sexual dysfunction showed less valid response rates.
