A model of suicidal behavior in posttraumatic stress disorder (PTSD): The mediating role of defeat and entrapment.

The aim of this study was to examine whether depression, hopelessness and perceptions of defeat and entrapment mediated the effects of posttraumatic stress disorder (PTSD) symptoms on suicidal behavior. The results support a recent theoretical model of suicide (The Schematic Appraisal Model of Suicide) which argues that perceptions of defeat and entrapment have a key role in the development of suicidal behaviors. We discuss the clinical implications of the findings.
