Post-traumatic stress disorder (PTSD) is a mental and behavioral disorder that develops from experiencing a traumatic event, such as sexual assault, warfare, traffic collisions, child abuse, domestic violence, or other threats on a person's life or well-being. Symptoms may include disturbing thoughts, feelings, or dreams related to the events, mental or physical distress to trauma-related cues, attempts to avoid trauma-related cues, alterations in the way a person thinks and feels, and an increase in the fight-or-flight response. These symptoms last for more than a month after the event. Young children are less likely to show distress, but instead may express their memories through play. A person with PTSD is at a higher risk of suicide and intentional self-harm.
Dissociation is a concept that has been developed over time and which concerns a wide array of experiences, ranging from a mild emotional detachment from the immediate surroundings, to a more severe disconnection from physical and emotional experiences. The major characteristic of all dissociative phenomena involves a detachment from reality, rather than a false perception of reality as in psychosis.
Frank A. Gerbode wrote of a method known as traumatic incident reduction (TIR). He is an Honors graduate of Stanford University and later pursued graduate studies in philosophy at Cambridge University. He received his medical degree from Yale University, and completed a psychiatric residency at Stanford University Medical Center in the early 1970s.
Psychological trauma is an emotional response caused by severe distressing events that are outside the normal range of human experiences. It must be understood by the affected person as directly threatening the affected person or their loved ones with death, severe bodily injury, or sexual violence; indirect exposure, such as from watching television news, may be extremely distressing and can produce an involuntary and possibly overwhelming physiological stress response, but does not produce trauma per se. Examples include violence, rape, or a terrorist attack.
Complex post-traumatic stress disorder is a stress-related mental disorder generally occurring in response to complex traumas, i.e., commonly prolonged or repetitive exposures to a series of traumatic events, within which individuals perceive little or no chance to escape.
Childhood trauma is often described as serious adverse childhood experiences (ACEs). Children may go through a range of experiences that classify as psychological trauma; these might include neglect, abandonment, sexual abuse, emotional abuse, and physical abuse, witnessing abuse of a sibling or parent, or having a mentally ill parent. These events have profound psychological, physiological, and sociological impacts and can have negative, lasting effects on health and well-being such as unsocial behaviors, attention deficit hyperactivity disorder (ADHD), and sleep disturbances. Similarly, children whose mothers have experienced traumatic or stressful events during pregnancy have an increased risk of mental health disorders and other neurodevelopmental disorders.
As defined by the United States Department of Veterans Affairs, military sexual trauma (MST) are experiences of sexual assault, or repeated threatening sexual harassment that occurred while a person was in the United States Armed Forces.
Memory and trauma is the deleterious effects that physical or psychological trauma has on memory.
Jennifer Joy Freyd is an American psychologist, researcher, author, educator, and speaker. Freyd is an extensively published scholar who is best known for her theories of betrayal trauma, DARVO, institutional betrayal, and institutional courage.
Vicarious trauma (VT) is a term invented by Irene Lisa McCann and Laurie Anne Pearlman that is used to describe how work with traumatized clients affects trauma therapists. The phenomenon had been known as secondary traumatic stress, a term coined by Charles Figley. In vicarious trauma, the therapist experiences a profound worldview change and is permanently altered by empathetic bonding with a client. This change is thought to have three requirements: empathic engagement and exposure to graphic, traumatizing material; exposure to human cruelty; and the reenactment of trauma in therapy. This can produce changes in a therapist's spirituality, worldview, and self-identity.
Jon Elhai is Distinguished Professor of clinical psychology at the University of Toledo. Elhai is known for being an expert in the assessment and diagnosis of Posttraumatic stress disorder (PTSD), forensic psychological assessment of PTSD, and detection of fabricated/malingered PTSD; as well as in internet addictions.
The Trauma Symptom Inventory (TSI) is a psychological evaluation/assessment instrument that taps symptoms of Posttraumatic stress disorder and other posttraumatic emotional problems. It was originally published in 1995 by its developer, John Briere. It is one of the most widely used measures of posttraumatic symptomatology.
PTSD or post-traumatic stress disorder, is a psychiatric disorder characterised by intrusive thoughts and memories, dreams or flashbacks of the event; avoidance of people, places and activities that remind the individual of the event; ongoing negative beliefs about oneself or the world, mood changes and persistent feelings of anger, guilt or fear; alterations in arousal such as increased irritability, angry outbursts, being hypervigilant, or having difficulty with concentration and sleep.
Perpetrator trauma, also known as perpetration- or participation-induced traumatic stress , occurs when the symptoms of posttraumatic stress disorder (PTSD) are caused by an act or acts of killing or similar horrific violence.
Institutional betrayal is a concept described by psychologist Jennifer Freyd, referring to "wrongdoings perpetrated by an institution upon individuals dependent on that institution, including failure to prevent or respond supportively to wrongdoings by individuals committed within the context of the institution". It is an extension of betrayal trauma theory. When institutions such as universities cover up violations such as rape, sexual assault and child sexual abuse, this institutional betrayal undermines survivors' recovery. In a landmark study in 2013, Carly P. Smith and Freyd documented psychological harm caused by institutional betrayal. A legal analysis concludes that this study is reliable under the Frye standard and the Daubert standard.
A moral injury is an injury to an individual's moral conscience and values resulting from an act of perceived moral transgression on the part of themselves or others. It produces profound feelings of guilt or shame, moral disorientation, and societal alienation. In some cases it may cause a sense of betrayal and anger toward colleagues, commanders, the organization, politics, or society at large.
Betrayal trauma is defined as a trauma perpetrated by someone with whom the victim is close to and reliant upon for support and survival. The concept originally introduced by Jennifer Freyd in 1994, betrayal trauma theory (BTT), addresses situations when people or institutions on which a person relies for protection, resources, and survival violate the trust or well-being of that person. BTT emphasizes the importance of betrayal as a core antecedent of dissociation implicitly aimed at preserving the relationship with the caregiver. BTT suggests that an individual, being dependent on another for support, will have a higher need to dissociate traumatic experiences from conscious awareness in order to preserve the relationship.
Andreas Maercker is a German clinical psychologist and international expert in traumatic stress-related mental disorders who works in Switzerland. He also contributed to lifespan and sociocultural aspects of trauma sequelae, e.g. the Janus-Face model of posttraumatic growth. Recently, he has been increasingly engaged in cultural clinical psychology.
DARVO is a reaction that perpetrators of wrongdoing, such as sexual offenders, may display in response to being held accountable for their behavior. Some researchers indicate that it is a common manipulation strategy of psychological abusers.
In psychology, Trauma-informed feminist therapy is a model of trauma for both men and women that incorporates the client's sociopolitical context.
