A collaborative study between Yale and the National Center for PTSD identified that veterans with posttraumatic stress disorder were more averse to ambiguity, but not risk, compared to veterans without PTSD when making choices between possible losses, but not gains.
Fifty-seven combat veterans participated in the grant-funded study, which sought to better understand the trauma-related symptom of individual uncertainty attitudes in combat veterans with and without PTSD.
The study was conducted by the Yale Department of Psychiatry in partnership with the Departments of Comparative Medicine and Neuroscience, and the National Center for PTSD. The paper was published in the journal Depression and Anxiety, in an issue that focused on PTSD.
