Trial of two models of a mental health intervention for internally displaced persons and veterans in Ukraine

To evaluate the impact of two different models of an evidence-based psychotherapy (Common Elements Treatment Approach - CETA) model for treating common mental health problems among internally displaced persons (IDPs) and veterans in Ukraine.  One model is a standard 8-12 session treatment regimen and the other model is a shortened 5 session version.  We will evaluate the effectiveness of each approach compared to a wait-control approach and also compare the short and long approaches  to demonstrate that that the short version is not worse than than the longer one.
