Perpetrator trauma

Perpetrator trauma is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Perpetrator trauma rather than just read about it. In short: Perpetrator trauma, also known as perpetration- or participation-induced traumatic stress, both abbreviated to PITS, occurs when the symptoms of posttraumatic stress disorder (PTSD) are caused by an act or acts of killing or similar violence. Perpetrator trauma is similar but distinct from moral injury, which focuses on the psychological, cultural, and spiritual aspects of a perceived moral transgression which produ…

Key takeaways

  • Perpetrator trauma belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Perpetrator trauma to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Perpetrator trauma from memory before moving on to harder problems.

Reference excerpt

Perpetrator trauma, also known as perpetration- or participation-induced traumatic stress, both abbreviated to PITS, occurs when the symptoms of posttraumatic stress disorder (PTSD) are caused by an act or acts of killing or similar violence. Perpetrator trauma is similar but distinct from moral injury, which focuses on the psychological, cultural, and spiritual aspects of a perceived moral transgression which produces profound shame.

As a psychiatric disorder

Status The DSM-5 addresses the idea of active participation as a cause of trauma under the discussion accompanying its definition of PTSD, and adds to the list of causal factors: "for military personnel, being a perpetrator, witnessing atrocities, or killing the enemy." There has been some study with combat veterans, people who carry out executions or torture, police who shoot in the line of duty, people who commit criminal homicide, and others.

Severity All studies that have considered the question of severity, have indicated that symptoms tend to be more severe for those who have killed, than for other causes of traumatization. One study using the U.S. government database of American veterans of Vietnam has suggested that the pattern of symptoms in combat veterans may be different in those who said they had killed, as opposed to those who said they had not. Symptoms include intrusive imagery, dreams, flashbacks and unwanted thoughts being more prominent; along with explosive outbursts of anger, concentration and memory problems being less prominent. To a lesser extent, hypervigilance, a sense of alienation, and the non-PTSD symptom of a sense of disintegration were found to be greater for those who answered yes on killing. Alcohol and cocaine use disorder appeared to be more severe.

Dream motifs Compared to the victim form of being traumatized, there are different dream motifs reported. While the eidetic dreams – that is, those that are like a video of the event playing in the head – can be experienced as they are with traumatized victims, other motifs also appear more commonly. One is of having the tables turned and being the one killed, or being very vulnerable in the same situation. Another motif is that of the victims accusing the dreaming person, or demanding to know why he or she did it. Also possible, is a motif of the self being split in two, so that the killer part of the person is seen as actually being a different person.

Therapy Therapies that have shown some effectiveness in the treatment of perpetrator trauma include group therapy, eye movement desensitization and reprocessing, Time Perspective Therapy and understanding how common the problem is. Those who suffer, many of whom participated in violence as a matter of social expectation, find it beneficial to know that they are having a normal reaction to an abnormal situation, and are not uniquely cowardly or crazy. Traditional remedies of atonement, forgiveness, and bearing witness have also stood the test of time as being helpful. More vigorous studies are needed for all these suggestions, as well as common PTSD therapies that have not yet been thoroughly explored, with the distinction of perpetration versus victimization in mind. Other proposed treatments have been proven to be ineffective. The "flooding" technique, technically called Prolonged Exposure, which desensitizes the sufferer of trauma by repeated exposure to reminders of it in controlled settings, appears to be a bad idea, counter-indicated when the trauma involved being active in inflicting harm. It may be that expressive writing, which most people find helpful in working through their traumas, instead increases anger in soldiers. Differences in what physiological mechanisms in what pharmaceutical drugs might be useful in therapy are not yet known. In the 11th century, soldiers involved in the Norman conquest of England, took part in the church administered Ermenfrid Penitential, to atone for, and mentally process the violence they participated in.

Cycles of violence Several of the symptoms are capable of causing or allowing for renewed acts of violence. The outbursts of anger can have an impact in domestic violence and street crime. The sense of emotional numbing, detachment and estrangement from other people can contribute to these, along with contributing to participation in further battle activities or to apathetic reactions when violence is done by others. Associated substance use disorders may also have connections to acts of violence.

Examples Perpetrator trauma has been documented among the perpetrators of the Holocaust, the Indonesian Communist Purges, the Cambodian genocide, the South African apartheid, and among slaughterhouse workers. In writing about the experiences of American soldiers during the Iraq War, the psychiatrist R. J. Lifton claims in the aftermath of the Haditha massacre:

The alleged crimes in Iraq, like My Lai, are examples of what I call an atrocity-producing situation—one so structured, psychologically and militarily, that ordinary people, men or women no better or worse than you or I, can commit atrocities. A major factor in all of these events was the emotional state of US soldiers as they struggled with angry grief over buddies killed by invisible adversaries, with a desperate need to identify an 'enemy.' Referring to the definition of "atrocity-producing situation", Morag (2013) was one of the first scholars to theorize perpetrator trauma and delineate the victim-perpetrator distinction in the context of the twenty-first century new war on terror. According to Morag's theorization, perpetrator trauma as an ethical trauma has been documented among Israeli soldiers during the Intifada as well US soldiers in Iraq and Afghanistan. Authors from the PTSD Journal have documented perpetrator trauma among slaughterhouse workers, stating that "these employees are hired to kill animals, such as pigs and cows that are largely gentle creatures. Carrying out this action requires workers to disconnect from what they are doing and from the creature standing before them. This emotional dissonance can lead to consequences such as domestic violence, social withdrawal, anxiety, substance use, and PTSD."

Worked examples

Example 1 — a first encounter with Perpetrator trauma

Start with the simplest possible case. Write down what Perpetrator trauma claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Perpetrator trauma before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Perpetrator trauma ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Perpetrator trauma

In research
Perpetrator trauma appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Perpetrator trauma in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Perpetrator trauma is common in secondary-school and first-year university syllabi. It links to neighbouring topics Post-traumatic stress disorder, Traumatology, so understanding it makes those chapters shorter.
In everyday life
Look for Perpetrator trauma outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
