The aim of this article is to test two hypotheses on the relationship between religiosity and war-related distress in Bosnia and Herzegovina. The article is based on a representative survey (n = 3,313) in Bosnia and Herzegovina during 2003–2004. The questionnaire included 15 items on war-related distress and 13 items on war experiences. From these items we developed a war-related distress scale, a war experiences scale, and several measures of religiosity. Regression analysis was used to examine the relationship between the war-related distress symptoms on the one hand, and religiosity and war experience on the other hand, controlling for a range of other variables. Religious beliefs and religious stability seem to protect against war-related distress, but religious activity works in the opposite direction to increase war-related distress. In conclusion, we found weak support for the first hypothesis, although the effects of religiosity on war-related distress seem more complex than expected. Our second hypotheses, that religiosity may work as a buffer to dampen the effects of war experiences on war-related distress, found no support.
