AB  - OBJECTIVE: To validate the Japanese versions of the Ullanlinna Narcolepsy Scale 
      (J-UNS) and Swiss Narcolepsy Scale (J-SNS) for screening narcolepsy in the 
      Japanese population and to discuss strategies for their use in hypersomniac 
      individuals. METHODS: We selected 451 outpatients with excessive daytime 
      sleepiness (EDS) already diagnosed according to the International Classification 
      of Sleep Disorders third edition. They responded to both scales twice at 1-month 
      intervals. After eliminating individuals who met the exclusion criteria, validity 
      and reliability analyses were performed on 408 and 381 participants, 
      respectively. RESULTS: Patients with narcolepsy type 1 (NT1) displayed higher 
      J-UNS and lower J-SNS scores than those with NT2 and other sleep disorders. The 
      intraclass correlation coefficients and weighted kappa coefficient for scale scores 
      in the total participants and patients with NT1 were >/=0.70 and >/= 0.40, 
      respectively, indicating high reliability. Furthermore, both the sensitivity and 
      specificity of these scales upon using the original cut-off scores (14 for UNS 
      and 0 for SNS) for detecting NT1 were 0.70 or >/=0.70, suggesting high validity. 
      Additionally, the receiver operating characteristic curve analysis revealed that 
      the best cut-off score did not change for the J-SNS but that for the J-UNS, it 
      increased to 18. In our study, the scale's sensitivity and specificity changed 
      from 96% to 82% and 58%-78%, respectively. CONCLUSIONS: Both scales revealed 
      satisfactory screening abilities for NT1 in the Japanese population. However, it 
      may be better to use J-UNS cut-off scores of 18 for a population with EDS.
