The study provides data of post-traumatic stress disorder, depression, anxiety and specific symptoms of mental and somatic disorders and determines the relationships between biographical data and experiences of violence to disease symptoms. The analysis of clinical interviews is presented, including a report on escape conditions, quantitative biographical data, and mental health data from a sample of 99 Kosovo-Albanians living in refugee camps in Germany which were documented and statistically analyzed. Serious forms of violence were reported. Independent of gender 40.2 per cent of the refugees suffered from symptoms of post-traumatic stress disorder, 80.3 per cent from symptoms of depression and of anxiety. Persons who had spent less time during forced displacement have lower prevalence of main outcome measures. Anxiety correlates with age, with a peak at the age group of 30-50 year old. War and organised violence are revealed as a serious threat to and a challenge for public health.
