Does the Current Concept of Stress Explain PTSD? [PDF]

open access: yes, 2015
Understanding the etiology of stress-related diseases such as PTSD requires a more fundamental understanding of stress. Since individuals may differ strongly in their response to a stressor, it is argued that stress includes not only the stimulus and the response but also the individual appraisal of the situation.
