title: Standardized rater training for the Hamilton Depression Rating Scale (HAMD-17) in psychiatric novices.
abstract: BACKGROUND
  Despite the long and widespread use of the Hamilton Depression Rating Scale (HAMD), standardized reliability studies in inexperienced raters are not available.
  
  
  METHODS
  Rater training was carried using three videotaped interviews with depressed patients in 21 psychiatric novices who had negligible previous experience with the HAMD. Chance-corrected coefficients of rating agreement with expert standards (weighted kappa, ICC) were computed for single items and the total score of the HAMD.
  
  
  RESULTS
  The results demonstrate sufficiently high interrater reliability (kappa>0.60) for most of the HAMD items and the total score (ICC=0.57-0.73). Three standardized HAMD training sessions seem adequate to establish satisfactory agreement among psychiatric novices.
  
  
  CONCLUSIONS
  The sample of video-taped interviews and, hence, the generalizability of the results, was restricted.
  
  
  CONCLUSIONS
  High inter-rater reliability of the HAMD justifies the use by clinically inexperienced researchers after standardized training.
