title: Achieving convergence between a community-based measure of explosive anger and a clinical interview for intermittent explosive disorder in Timor-Leste.
abstract: BACKGROUND
  There is growing research interest in understanding and analyzing explosive forms of anger. General epidemiological studies have focused on the DSM-IV category of Intermittent Explosive Disorder (IED), while refugee and post-conflict research have used culturally-based indices of explosive anger. The aim of this study was to test the convergence of a culturally-sensitive community measure of explosive anger with a structured clinical interview diagnosis of IED in Timor-Leste, a country with a history of significant mass violence and displacement.
  
  
  METHODS
  A double-blind clinical concordance study was conducted amongst a stratified community sample in post-conflict Timor-Leste (n=85) to compare a community measure of anger against the Structured Clinical Interview (SCID) module for IED.
  
  
  RESULTS
  Clinical concordance between the two measures was high: the area under the curve (AUC) index was 0.90 (95% CI: 0.83-0.98); sensitivity and specificity were 93.3% and 87.5% respectively.
  
  
  CONCLUSIONS
  Response rates were modest due to the participant's time commitments.
  
  
  CONCLUSIONS
  It is possible to achieve convergence between culturally-sensitive measures of explosive anger and the DSM-IV construct of IED, allowing comparison of findings across settings and populations.
