Survivor guilt (or survivor's guilt; also called survivor syndrome or survivor's syndrome) is a mental condition that occurs when a person perceives themselves to have done wrong by surviving a traumatic event when others did not. It may be found among survivors of murder, terrorism, combat, natural disasters, epidemics, among the friends and family of those who have died by suicide, and in non-mortal situations such as among those whose colleagues are laid off. The experience and manifestation of survivor's guilt will depend on an individual's psychological profile. When the Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV) was published, survivor guilt was removed as a recognized specific diagnosis, and redefined as a significant symptom of post traumatic stress disorder (PTSD).
Survivor guilt was first identified during the 1960s. Several therapists recognized similar if not identical conditions among Holocaust survivors. Similar signs and symptoms have been recognized in survivors of traumatic situations including combat, natural disasters, terrorist attacks, air-crashes and wide-ranging job layoffs. A variant form has been found among rescue and emergency services personnel who blame themselves for doing too little to help those in danger, and among therapists, who may feel a form of guilt in the face of their patients' suffering.
Stephen Joseph, a psychologist at the University of Warwick, has studied the survivors of the capsizing of the MS Herald of Free Enterprise which killed 193 of the 459 passengers. His studies showed that 60 percent of the survivors suffered from survivor guilt. Joseph went on to say: "There were three types: first, there was guilt about staying alive while others died; second, there was guilt about the things they failed to do – these people often suffered post-traumatic 'intrusions' as they relived the event again and again; third, there were feelings of guilt about what they did do, such as scrambling over others to escape. These people usually wanted to avoid thinking about the catastrophe. They didn't want to be reminded of what really happened.
