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.

Limitations

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.
