Psychological trauma is a type of damage to the psyche that occurs as a result of a severely distressing event.

Trauma, which means "injured" in Greek,^[1] is often the result of an overwhelming amount of stress that exceeds one's ability to cope or integrate the emotions involved with that experience.^[2] A traumatic event involves one experience, or repeating events with the sense of being overwhelmed that can be delayed by weeks, years, or even decades as the person struggles to cope with the immediate circumstances, eventually leading to serious, long-term negative consequences, often overlooked even by mental health professionals: "If clinicians fail to look through a trauma lens and to conceptualize client problems as related possibly to current or past trauma, they may fail to see that trauma victims, young and old, organize much of their lives around repetitive patterns of reliving and warding off traumatic memories, reminders, and affects." ^[3]

Trauma can be caused by a wide variety of events, but there are a few common aspects. There is frequently a violation of the person's familiar ideas about the world and of their human rights, putting the person in a state of extreme confusion and insecurity. This is also seen when institutions that are depended upon for survival, violate or betray or disillusion the person in some unforeseen way.^[4]

Psychologically traumatic experiences often involve physical trauma that threatens one's survival and sense of security.^[5] Typical causes and dangers of psychological trauma include harassment, embarrassment, sexual abuse, employment discrimination, police brutality, bullying, domestic violence, indoctrination, being the victim of an alcoholic parent, the threat of either, or the witnessing of either, particularly in childhood, life-threatening medical conditions, medication-induced trauma.^[6] Catastrophic natural disasters such as earthquakes and volcanic eruptions, war or other mass violence can also cause psychological trauma. Long-term exposure to situations such as extreme poverty or milder forms of abuse, such as verbal abuse, exist independently of physical trauma but still generate psychological trauma.

However, the definition of trauma differs among individuals by their subjective experiences, not the objective facts. People will react to similar events differently. In other words, not all people who experience a potentially traumatic event will actually become psychologically traumatized.^[7] This discrepancy in risk rate can be attributed to protective factors some individuals may have that enable them to cope with trauma. Some examples are mild exposure to stress early in life,^[8] resilience characteristics, and active seeking of help.^[9]

Some theories suggest childhood trauma can increase one's risk for psychological disorders including posttraumatic stress disorder (PTSD), depression, and substance abuse. Childhood adversity is associated with heightened neuroticism scores during adulthood.^[10] Parts of the brain in a growing child are developing in a sequential and hierarchical order, from least complex to most complex. The brains neurons are designed to change in response to the constant external signals and stimulation, receiving and storing new information. This allows the brain to continually respond to its surroundings and promote survival. Our five main sensory signals contribute to the developing brain structure and its function.^[11] Infants and children begin to create internal representations of their external environment shortly after birth. The more frequent a specific pattern of brain neurons is activated, the more permanent the internal representation associated with the pattern becomes.^[12] This causes sensitization in the brain towards the specific neural network. Because of this sensitization, the neural pattern can be activated by decreasingly less external stimuli. Childhood abuse tends to have the most complications with long-term effects out of all forms of trauma because it occurs during the most sensitive and critical stages of psychological development.^[9] It could also lead to violent behavior, possibly as extreme as serial murder. For example, Hickey's Trauma-Control Model suggests that "childhood trauma for serial murderers may serve as a triggering mechanism resulting in an individual's inability to cope with the stress of certain events." ^[13]

Symptoms

People who go through these types of extremely traumatic experiences often have certain symptoms and problems afterward. How severe these symptoms are depends on the person, the type of trauma involved, and the emotional support they receive from others. Reactions to and symptoms of trauma can be wide and varied, and differ in severity from person to person. A traumatized individual may experience one or several of them. Carlson, Eve B.; Josef Ruzek.

After a traumatic experience, a person may re-experience the trauma mentally and physically, hence avoiding trauma reminders, also called triggers, as this can be uncomfortable and even painful. They may turn to psychoactive substances including alcohol to try to escape the feelings. Re-experiencing symptoms are a sign that the body and mind are actively struggling to cope with the traumatic experience.

Triggers and cues act as reminders of the trauma, and can cause anxiety and other associated emotions. Often the person can be completely unaware of what these triggers are. In many cases this may lead a person suffering from traumatic disorders to engage in disruptive or self-destructive coping mechanisms, often without being fully aware of the nature or causes of their own actions. Panic attacks are an example of a psychosomatic response to such emotional triggers, which can sometimes lead to severe-case psychosis.

Consequently, intense feelings of anger may frequently surface, sometimes in inappropriate or unexpected situations, as danger may always seem to be present, as much as it is actually present and experienced from past events. Upsetting memories such as images, thoughts, or flashbacks may haunt the person, and nightmares may be frequent.^[14] Insomnia may occur as lurking fears and insecurity keep the person vigilant and on the lookout for danger, both day and night. Trauma doesn't only cause changes in one's daily functions but could also lead to morphological changes. Such epigenetic changes can be passed on to the next generations, thus making genetics as one of the components of the causes of psychological trauma. However, some people are born or later develop protective factors such as genetics and sex that help lower their risk of psychological trauma.^[15]

The person may not remember what actually happened, while emotions experienced during the trauma may be re-experienced without the person understanding why (see Repressed memory). This can lead to the traumatic events being constantly experienced as if they were happening in the present, preventing the subject from gaining perspective on the experience. This can produce a pattern of prolonged periods of acute arousal punctuated by periods of physical and mental exhaustion.^[16]

In time, emotional exhaustion may set in, leading to distraction, and clear thinking may be difficult or impossible. Emotional detachment, as well as dissociation or "numbing out", can frequently occur. Dissociating from the painful emotion includes numbing all emotion, and the person may seem emotionally flat, preoccupied, distant, or cold. The person can become confused in ordinary situations and have memory problems.

Some traumatized people may feel permanently damaged when trauma symptoms do not go away and they do not believe their situation will improve. This can lead to feelings of despair, loss of self-esteem, and frequently depression. If important aspects of the person's self and world understanding have been violated, the person may call their own identity into question.^[17] Often despite their best efforts, traumatized parents may have difficulty assisting their child with emotion regulation, attribution of meaning, and containment of post-traumatic fear in the wake of the child's traumatization, leading to adverse consequences for the child.^[18][19] In such instances, it is in the interest of the parent(s) and child for the parent(s) to seek consultation as well as to have their child receive appropriate mental health services.

Situational trauma

Trauma can be caused by man-made and natural disasters, including war, abuse, violence, earthquakes, mechanized accidents (car, train, or plane crashes, etc.) or medical emergencies.

Responses to psychological trauma: There are several behavioral responses common towards stressors including the proactive, reactive, and passive responses. Proactive responses include attempts to address and correct a stressor before it has a noticeable effect on lifestyle. Reactive responses occur after the stress and possible trauma has occurred, and are aimed more at correcting or minimizing the damage of a stressful event. A passive response is often characterized by an emotional numbness or ignorance of a stressor.

Those who are able to be proactive can often overcome stressors and are more likely to be able to cope well with unexpected situations. On the other hand, those who are more reactive will often experience more noticeable effects from an unexpected stressor. In the case of those who are passive, victims of a stressful event are more likely to suffer from long-term traumatic effects and often enact no intentional coping actions. These observations may suggest that the level of trauma associated with a victim is related to such independent coping abilities.

There is also a distinction between trauma induced by recent situations and long-term trauma which may have been buried in the unconscious from past situations such as childhood abuse. Trauma is often overcome through healing; in some cases this can be achieved by recreating or revisiting the origin of the trauma under more psychologically safe circumstances, such as with a therapist.

Assessment

The experience and outcomes of psychological trauma can be assessed in a number of ways.^[20] Within the context of a clinical interview, the risk for imminent danger to the self or others is important to address but is not the focus of assessment. In most cases, it will not be necessary to involve contacting emergency services (e.g., medical, psychiatric, law enforcement) to ensure the individuals safety; members of the individual’s social support network are much more critical.

Understanding and accepting the psychological state an individual is in is paramount. There are many mis-conceptions of what it means for a traumatized individual to be in crisis or 'psychosis.' These are times when an individual is in inordinate amounts of pain and cannot comfort themselves, if treated humanely and respectfully they will not get to a state in which they are a danger. In these situations it is best to provide a supportive, caring environment and communicate to the individual that no matter the circumstance they will be taken seriously and not just as a sick, delusional individual. It is vital for the assessor to understand that what is going on in the traumatized persons head is valid and real. If deemed appropriate, the assessing clinician may proceed by inquiring about both the traumatic event and the outcomes experienced (e.g., posttraumatic symptoms, dissociation, substance abuse, somatic symptoms, psychotic reactions). Such inquiry occurs within the context of established rapport and is completed in an empathic, sensitive, and supportive manner. The clinician may also inquire about possible relational disturbance, such as alertness to interpersonal danger, abandonment issues, and the need for self-protection via interpersonal control. Through discussion of interpersonal relationships, the clinician is better able to assess the individual’s ability to enter and sustain a clinical relationship.

During assessment, individuals may exhibit activation responses in which reminders of the traumatic event trigger sudden feelings (e.g., distress, anxiety, anger), memories, or thoughts relating to the event. Because individuals may not yet be capable of managing this distress, it is necessary to determine how the event can be discussed in such a way that will not “retraumatize” the individual. It is also important to take note of such responses, as these responses may aid the clinician in determining the intensity and severity of possible posttraumatic stress as well as the ease with which responses are triggered. Further, it is important to note the presence of possible avoidance responses. Avoidance responses may involve the absence of expected activation or emotional reactivity as well as the use of avoidance mechanisms (e.g., substance use, effortful avoidance of cues associated with the event, dissociation).

In addition to monitoring activation and avoidance responses, clinicians carefully observe the individual’s strengths or difficulties with affect regulation (i.e., affect tolerance and affect modulation). Such difficulties may be evidenced by mood swings, brief yet intense depressive episodes, or self-mutilation. The information gathered through observation of affect regulation will guide the clinician’s decisions regarding the individual’s readiness to partake in various therapeutic activities.

Though assessment of psychological trauma may be conducted in an unstructured manner, assessment may also involve the use of a structured interview. Such interviews might include the Clinician-Administered PTSD Scale (CAPS; Blake et al., 1995), Acute Stress Disorder Interview (ASDI; Bryant, Harvey, Dang, & Sackville, 1998), Structured Interview for Disorders of Extreme Stress (SIDES; Pelcovitz et al., 1997), Structured Clinical Interview for DSM-IV Dissociative Disorders- Revised (SCID-D; Steinberg, 1994), and Brief Interview for Posttraumatic Disorders (BIPD; Briere, 1998).

Lastly, assessment of psychological trauma might include the use of self-administered psychological tests. Individuals’ scores on such tests are compared to normative data in order to determine how the individual’s level of functioning compares to others in a sample representative of the general population. Psychological testing might include the use of generic tests (e.g., MMPI-2, MCMI-III, SCL-90-R) to assess non-trauma-specific symptoms as well as difficulties related to personality. In addition, psychological testing might include the use of trauma-specific tests to assess posttraumatic outcomes. Such tests might include the Posttraumatic Stress Diagnostic Scale (PDS; Foa, 1995), Davidson Trauma Scale (DTS: Davidson et al., 1997), Detailed Assessment of Posttraumatic Stress (DAPS; Briere, 2001), Trauma Symptom Inventory (TSI: Briere, 1995), Trauma Symptom Checklist for Children (TSCC; Briere, 1996), Traumatic Life Events Questionnaire (TLEQ: Kubany et al., 2000), and Trauma-related Guilt Inventory (TRGI: Kubany et al., 1996).

Treatment

A number of psychotherapy approaches have been designed with the treatment of trauma in mind—EMDR, Somatic Experiencing, Biofeedback, Internal Family Systems Therapy, and Sensorimotor psychotherapy.

There is a large body of empirical support for the use of cognitive behavioral therapy ^[21][22] for the treatment of trauma-related symptoms,^[23] including Posttraumatic Stress Disorder. Institute of Medicine guidelines identify cognitive behavioral therapies as the most effective treatments for PTSD.^[24] Two of these cognitive behavioral therapies, Prolonged Exposure ^[25] and Cognitive Processing Therapy,^[26] are being disseminated nationally by the Department of Veterans Affairs for the treatment of PTSD.^[27][28] Recent studies show that a combination of treatments involving the dialectical behavior therapy (DBT), often used for borderline personality disorder, and exposure therapy is highly effective in treating psychological trauma.^[15] If however psychological trauma has caused dissociative disorders or complex PTSD trauma model approach also known as phase-oriented treatment of structural dissociation has been proven to work better than simple cognitive approach and so trauma therapy is indicated.^[29]

Recent studies have also shown that medications such as the new anti-depressants are effective when used in combination with other psychological approaches.

In psychoanalysis

French neurologist Jean-Martin Charcot arguedTemplate:When that psychological trauma was the origin of all instances of the mental illness known as hysteria. Charcot's "traumatic hysteria" often manifested as a paralysis that followed a physical trauma, typically years later after what Charcot described as a period of "incubation". Sigmund Freud, Charcot's student and the father of psychoanalysis, examined the concept of psychological trauma throughout his career. Jean Laplanche has given a general description of Freud's understanding of trauma, which varied significantly over the course of Freud's career: "An event in the subject's life, defined by its intensity, by the subject's incapacity to respond adequately to it and by the upheaval and long-lasting effects that it brings about in the psychical organization".^[30]

The French psychoanalyst Jacques Lacan claimed that what he called "The Real" had a traumatic quality external to symbolization. As an object of anxiety, Lacan maintained that The Real is "the essential object which isn't an object any longer, but this something faced with which all words cease and all categories fail, the object of anxiety par excellence".^[31]

Stress disorders

All psychological traumas originate from stress, a physiological response to an unpleasant stimulus.^[32] Long term stress increases the risk of poor mental health and mental disorders, which can be attributed to secretion of glucocorticoids for a long period of time. Such prolonged exposure causes many physiological dysfunctions such as the suppression of the immune system and increase in blood pressure.^[33] Not only does it affect the body physiologically, but a morphological change in the hippocampus also takes place. Studies showed that extreme stress early in life can disrupt normal development of hippocampus and impact its functions in adulthood. Studies surely show a correlation between the size of hippocampus and one's susceptibility to stress disorders.^[34] In times of war, psychological trauma has been known as shell shock or combat stress reaction. Psychological trauma may cause an acute stress reaction which may lead on to posttraumatic stress disorder (PTSD). PTSD emerged as the label for this condition after the Vietnam War in which many veterans returned to their respective countries demoralized, and sometimes, addicted to psychoactive substances. The symptoms of PTSD must persist for at least a month for diagnosis. The main symptoms of PTSD consist of four main categories: Trauma (i.e. intense fear), reliving (i.e. flashbacks), avoidance behavior (i.e. emotional numbing), and hypervigilance (i.e. irritability).^[35] Research shows that about 60% of the US population reported as having experienced at least one traumatic symptom in their lives but only a small proportion actually develops PTSD. There is a correlation between the risk of PTSD and whether or not the act was inflicted deliberately by the offender.^[15] Psychological trauma is treated with therapy and, if indicated, psychotropic medications.

The term Continuous Post Traumatic Stress Disorder (CTSD) ^[36] was introduced into the trauma literature by Gill Straker (1987). It was originally used by South African clinicians to describe the effects of exposure to frequent, high levels of violence usually associated with civil conflict and political repression. The term is also applicable to the effects of exposure to contexts in which gang violence and crime are endemic as well as to the effects of ongoing exposure to life threats in high-risk occupations such as police, fire and emergency services.

As one of the processes of treatment, confrontation with their sources of trauma plays a crucial role. While debriefing people immediately after an event has not been shown to reduce incidence of post-traumatic stress, coming alongside people experiencing trauma in a supportive way has become standard practice.^[37]
