Six-year longitudinal study of pathways leading to explosive anger involving the traumas of recurrent conflict and the cumulative sense of injustice in Timor-Leste.

Sampling constraints caution against generalizing our findings to other populations. Nevertheless, our data suggest that explosive anger may persist for a prolonged period of time following mass conflict and that the response pattern is initiated and maintained by recurrent trauma exposure associated with a sense of injustice. Averting recurrence of mass violence and addressing persisting feelings of injustice may assist in reducing anger in conflict-affected societies. Whether explosive anger at the individual level increases risk of collective violence under conditions of social and political instability requires further inquiry.
