We assessed symptoms of psychological distress among a population-based sample of 9000-plus adults in Burundi during (1998) and after (2007) armed conflict. After exploratory and confirmatory factor analysis to an 8-item, self-report measure, we identified two domains of psychological distress "Depression/Anxiety" and "Functioning" with good fit to data. The questionnaire was invariant in males and females. Depression and Anxiety symptoms during conflict were more frequently reported than Functioning symptoms; all symptoms were more frequently reported by women. Psychological distress was found in 44 % of individuals during conflict and in 29 % 2 years after the conflict. Results call for further research in Burundi that can inform the development of mental health interventions.
