title: The premature ejaculation diagnostic tool (PEDT): linguistic validity of the Chinese version.
abstract: BACKGROUND
  The premature ejaculation diagnostic tool (PEDT) was developed to standardize the diagnosis of PE and has been applied in many countries. However, a linguistic validation of the Chinese version of PEDT does not exist.
  
  
  OBJECTIVE
  This study aims to undertake the Chinese validation of the PEDT and to evaluate its association with self-estimated intravaginal ejaculatory latency time (IELT) and clinical expert diagnosis of PE.
  
  
  METHODS
  A Chinese version of PEDT was confirmed by andrologist and bilingual linguist. Participants were recruited among seven different communities of Shanghai from 2011 to 2012, and their information regarding self-reported PE, self-estimated IELT, expert diagnosis of PE, and PEDT scores were collected.
  
  
  METHODS
  Validity of the PEDT and its association with clinical expert diagnosis of PE and self-estimated IELT were analyzed.
  
  
  RESULTS
  A total of 143 patients without PE (mean age 55.11 ± 7.65 years) and 100 men with PE (mean age 53.07 ± 8.08 years) were enrolled for validation. Of the patients in PE group, the number of men reporting self-estimated IELTs of ≤1, 1-2, and >2 minutes were 34 (34.0%), 22 (22.0%), and 44 (44.0%), respectively. The Cronbach's alpha score (α = 0.77) showed adequate internal consistency, and the test-retest correlation coefficients of each item (r ≥ 0.70, P < 0.001) indicated excellent stability over time. The frequency of agreement showed that there was excellent concordance between PEDT diagnosis and clinician diagnosis when the PEDT scores ≥11. An adequate correlation was found between total PEDT score and self-estimated IELT (ρ = -0.396, P < 0.001), and sensitivity and specificity analyses suggested a score of ≤8 indicated no time-defined PE (self-estimated IELT ≤1 minute).
  
  
  CONCLUSIONS
  The Chinese version of PEDT is valid in screening the presence of PE among Chinese men. The PEDT showed an adequate negative correlation with self-estimated IELT and an excellent concordance with clinician diagnosis of PE.
