Emotional dysregulation

Some trauma survivors have difficulty regulating emotions such as anger, anxiety, sadness, and shame—this is more so when the trauma occurred at a young age (van der Kolk, Roth, Pelcovitz, & Mandel, 1993). In individuals who are older and functioning well prior to the trauma, such emotional dysregulation is usually short lived and represents an immediate reaction to the trauma, rather than an ongoing pattern. Self-medication—namely, substance abuse—is one of the methods that traumatized people use in an attempt to regain emotional control, although ultimately it causes even further emotional dysregulation (e.g., substance-induced changes in affect during and after use). Other efforts toward emotional regulation can include engagement in high-risk or self-injurious behaviors, disordered eating, compulsive behaviors such as gambling or overworking, and repression or denial of emotions; however, not all behaviors associated with self-regulation are considered negative. In fact, some individuals find creative, healthy, and industrious ways to manage strong affect generated by trauma, such as through renewed commitment to physical activity or by creating an organization to support survivors of a particular trauma.

Traumatic stress tends to evoke two emotional extremes: feeling either too much (overwhelmed) or too little (numb) emotion. Treatment can help the client find the optimal level of emotion and assist him or her with appropriately experiencing and regulating difficult emotions. In treatment, the goal is to help clients learn to regulate their emotions without the use of substances or other unsafe behavior. This will likely require learning new coping skills and how to tolerate distressing emotions; some clients may benefit from mindfulness practices, cognitive restructuring, and trauma-specific desensitization approaches, such as exposure therapy and eye movement desensitization and reprocessing (EMDR; refer to Part 1, Chapter 6, for more information on trauma-specific therapies).

Numbing

Numbing is a biological process whereby emotions are detached from thoughts, behaviors, and memories. In the following case illustration, Sadhanna’s numbing is evidenced by her limited range of emotions associated with interpersonal interactions and her inability to associate any emotion with her history of abuse. She also possesses a belief in a foreshortened future. A prospective longitudinal study (Malta, Levitt, Martin, Davis, & Cloitre, 2009) that followed the development of PTSD in disaster workers highlighted the importance of understanding and appreciating numbing as a traumatic stress reaction. Because numbing symptoms hide what is going on inside emotionally, there can be a tendency for family members, counselors, and other behavioral health staff to assess levels of traumatic stress symptoms and the impact of trauma as less severe than they actually are.

Somatization

Somatization indicates a focus on bodily symptoms or dysfunctions to express emotional distress. Somatic symptoms are more likely to occur with individuals who have traumatic stress reactions, including PTSD. People from certain ethnic and cultural backgrounds may initially or solely present emotional distress via physical ailments or concerns. Many individuals who present with somatization are likely unaware of the connection between their emotions and the physical symptoms that they’re experiencing. At times, clients may remain resistant to exploring emotional content and remain focused on bodily complaints as a means of avoidance. Some clients may insist that their primary problems are physical even when medical evaluations and tests fail to confirm ailments. In these situations, somatization may be a sign of a mental illness. However, various cultures approach emotional distress through the physical realm or view emotional and physical symptoms and well-being as one. It is important not to assume that clients with physical complaints are using somatization as a means to express emotional pain; they may have specific conditions or disorders that require medical attention. Foremost, counselors need to refer for medical evaluation.

Biology of trauma

Trauma biology is an area of burgeoning research, with the promise of more complex and explanatory findings yet to come. Although a thorough presentation on the biological aspects of trauma is beyond the scope of this publication, what is currently known is that exposure to trauma leads to a cascade of biological changes and stress responses. These biological alterations are highly associated with PTSD, other mental illnesses, and substance use disorders. These include:

• Changes in limbic system functioning.
• Hypothalamic–pituitary–adrenal axis activity changes with variable cortisol levels.
• Neurotransmitter-related dysregulation of arousal and endogenous opioid systems.

As a clear example, early ACEs such as abuse, neglect, and other traumas affect brain development and increase a person’s vulnerability to encountering interpersonal violence as an adult and to developing chronic diseases and other physical illnesses, mental illnesses, substance-related disorders, and impairment in other life areas (Centers for Disease Control and Prevention, 2012).

Hyperarousal and sleep disturbances

A common symptom that arises from traumatic experiences is hyperarousal (also called hypervigilance). Hyperarousal is the body’s way of remaining prepared. It is characterized by sleep disturbances, muscle tension, and a lower threshold for startle responses and can persist years after trauma occurs. It is also one of the primary diagnostic criteria for PTSD.

Hyperarousal is a consequence of biological changes initiated by trauma. Although it serves as a means of self-protection after trauma, it can be detrimental. Hyperarousal can interfere with an individual’s ability to take the necessary time to assess and appropriately respond to specific input, such as loud noises or sudden movements. Sometimes, hyperarousal can produce overreactions to situations perceived as dangerous when, in fact, the circumstances are safe.

Along with hyperarousal, sleep disturbances are very common in individuals who have experienced trauma. They can come in the form of early awakening, restless sleep, difficulty falling asleep, and nightmares. Sleep disturbances are most persistent among individuals who have trauma-related stress; the disturbances sometimes remain resistant to intervention long after other traumatic stress symptoms have been successfully treated. Numerous strategies are available beyond medication, including good sleep hygiene practices, cognitive rehearsals of nightmares, relaxation strategies, and nutrition.

Feeling different

An integral part of experiencing trauma is feeling different from others, whether or not the trauma was an individual or group experience. Traumatic experiences typically feel surreal and challenge the necessity and value of mundane activities of daily life. Survivors often believe that others will not fully understand their experiences, and they may think that sharing their feelings, thoughts, and reactions related to the trauma will fall short of expectations. However horrid the trauma may be, the experience of the trauma is typically profound.

The type of trauma can dictate how an individual feels different or believes that they are different from others. Traumas that generate shame will often lead survivors to feel more alienated from others—believing that they are “damaged goods.” When individuals believe that their experiences are unique and incomprehensible, they are more likely to seek support, if they seek support at all, only with others who have experienced a similar trauma.

Triggers and flashbacks

Dissociation, depersonalization, and derealization

Dissociation is a mental process that severs connections among a person’s thoughts, memories, feelings, actions, and/or sense of identity. Most of us have experienced dissociation—losing the ability to recall or track a particular action (e.g., arriving at work but not remembering the last minutes of the drive). Dissociation happens because the person is engaged in an automatic activity and is not paying attention to his or her immediate environment. Dissociation can also occur during severe stress or trauma as a protective element whereby the individual incurs distortion of time, space, or identity. This is a common symptom in traumatic stress reactions.

Dissociation helps distance the experience from the individual. People who have experienced severe or developmental trauma may have learned to separate themselves from distress to survive. At times, dissociation can be very pervasive and symptomatic of a mental disorder, such as dissociative identity disorder (DID; formerly known as multiple personality disorder). According to the DSM-5, “dissociative disorders are characterized by a disruption of and/or discontinuity in the normal integration of consciousness, memory, identity, emotion, perception, body representation, motor control, and behavior” (APA, 2013a, p. 291). Dissociative disorder diagnoses are closely associated with histories of severe childhood trauma or pervasive, human-caused, intentional trauma, such as that experienced by concentration camp survivors or victims of ongoing political imprisonment, torture, or long-term isolation. A mental health professional, preferably with significant training in working with dissociative disorders and with trauma, should be consulted when a dissociative disorder diagnosis is suspected.

The characteristics of DID can be commonly accepted experiences in other cultures, rather than being viewed as symptomatic of a traumatic experience. For example, in non-Western cultures, a sense of alternate beings within oneself may be interpreted as being inhabited by spirits or ancestors (Kirmayer, 1996). Other experiences associated with dissociation include depersonalization—psychologically “leaving one’s body,” as if watching oneself from a distance as an observer or through derealization, leading to a sense that what is taking place is unfamiliar or is not real.

If clients exhibit signs of dissociation, behavioral health service providers can use grounding techniques to help them reduce this defense strategy. One major long-term consequence of dissociation is the difficulty it causes in connecting strong emotional or physical reactions with an event. Often, individuals may believe that they are going crazy because they are not in touch with the nature of their reactions. By educating clients on the resilient qualities of dissociation while also emphasizing that it prevents them from addressing or validating the trauma, individuals can begin to understand the role of dissociation. All in all, it is important when working with trauma survivors that the intensity level is not so great that it triggers a dissociative reaction and prevents the person from engaging in the process.

Reenactments

A hallmark symptom of trauma is reexperiencing the trauma in various ways. Reexperiencing can occur through reenactments (literally, to “redo”), by which trauma survivors repetitively relive and recreate a past trauma in their present lives. This is very apparent in children, who play by mimicking what occurred during the trauma, such as by pretending to crash a toy airplane into a toy building after seeing televised images of the terrorist attacks on the World Trade Center on September 11, 2001. Attempts to understand reenactments are very complicated, as reenactments occur for a variety of reasons. Sometimes, individuals reenact past traumas to master them. Examples of reenactments include a variety of behaviors: self-injurious behaviors, hypersexuality, walking alone in unsafe areas or other high-risk behaviors, driving recklessly, or involvement in repetitive destructive relationships (e.g., repeatedly getting into romantic relationships with people who are abusive or violent), to name a few.

Self-harm and self-destructive behaviors

Self-harm is any type of intentionally self-inflicted harm, regardless of the severity of injury or whether suicide is intended. Often, self-harm is an attempt to cope with emotional or physical distress that seems overwhelming or to cope with a profound sense of dissociation or being trapped, helpless, and “damaged” (Herman, 1997; Santa Mina & Gallop, 1998). Self-harm is associated with past childhood sexual abuse and other forms of trauma as well as substance abuse. Thus, addressing self-harm requires attention to the client’s reasons for self-harm. More than likely, the client needs help recognizing and coping with emotional or physical distress in manageable amounts and ways.

Among the self-harm behaviors reported in the literature are cutting, burning skin by heat (e.g., cigarettes) or caustic liquids, punching hard enough to self-bruise, head banging, hair pulling, self-poisoning, inserting foreign objects into bodily orifices, excessive nail biting, excessive scratching, bone breaking, gnawing at flesh, interfering with wound healing, tying off body parts to stop breathing or blood flow, swallowing sharp objects, and suicide. Cutting and burning are among the most common forms of self-harm.

Self-harm tends to occur most in people who have experienced repeated and/or early trauma (e.g., childhood sexual abuse) rather than in those who have undergone a single adult trauma (e.g., a community-wide disaster or a serious car accident). There are strong associations between eating disorders, self-harm, and substance abuse (Claes & Vandereycken, 2007; for discussion, see Harned, Najavits, & Weiss, 2006). Self-mutilation is also associated with (and part of the diagnostic criteria for) a number of personality disorders, including borderline and histrionic, as well as DID, depression, and some forms of schizophrenia; these disorders can co-occur with traumatic stress reactions and disorders.

It is important to distinguish self-harm that is suicidal from self-harm that is not suicidal and to assess and manage both of these very serious dangers carefully. Most people who engage in self-harm are not doing so with the intent to kill themselves (Noll, Horowitz, Bonanno, Trickett, & Putnam, 2003)—although self-harm can be life threatening and can escalate into suicidality if not managed therapeutically. Self-harm can be a way of getting attention or manipulating others, but most often it is not. Self-destructive behaviors such as substance abuse, restrictive or binge eating, reckless automobile driving, or high-risk impulsive behavior are different from self-harming behaviors but are also seen in clients with a history of trauma. Self-destructive behaviors differ from self-harming behaviors in that there may be no immediate negative impact of the behavior on the individual; they differ from suicidal behavior in that there is no intent to cause death in the short term.

However, as with self-harming behavior, self-destructive behavior needs to be recognized and addressed and may persist—or worsen—without intervention.

Consumption of substances

Substance use often is initiated or increased after trauma. Clients in early recovery— especially those who develop PTSD or have it reactivated—have a higher relapse risk if they experience a trauma. In the first 2 months after September 11, 2001, more than a quarter of New Yorker residents who smoked cigarettes, drank alcohol, or used marijuana (about 265,000 people) increased their consumption. The increases continued 6 months after the attacks (Vlahov, Galea, Ahern, Resnick, & Kilpatrick, 2004). A study by the Substance Abuse and Mental Health Services Administration (SAMHSA, Office of Applied Studies, 2002) used National Survey on Drug Use and Health data to compare the first three quarters of 2001 with the last quarter and reported an increase in the prevalence rate for alcohol use among people 18 or older in the New York metropolitan area during the fourth quarter.

Interviews with New York City residents who were current or former cocaine or heroin users indicated that many who had been clean for 6 months or less relapsed after September 11, 2001. Others, who lost their income and could no longer support their habit, enrolled in methadone programs (Weiss et al., 2002). After the Oklahoma City bombing in 1995, Oklahomans reported double the normal rate of alcohol use, smoking more cigarettes, and a higher incidence of initiating smoking months and even years after the bombing (Smith, Christiansen, Vincent, & Hann, 1999).

Avoidance

Avoidance often coincides with anxiety and the promotion of anxiety symptoms. Individuals begin to avoid people, places, or situations to alleviate unpleasant emotions, memories, or circumstances. Initially, the avoidance works, but over time, anxiety increases and the perception that the situation is unbearable or dangerous increases as well, leading to a greater need to avoid. Avoidance can be adaptive, but it is also a behavioral pattern that reinforces perceived danger without testing its validity, and it typically leads to greater problems across major life areas (e.g., avoiding emotionally oriented conversations in an intimate relationship). For many individuals who have traumatic stress reactions, avoidance is commonplace. A person may drive 5 miles longer to avoid the road where he or she had an accident. Another individual may avoid crowded places in fear of an assault or to circumvent strong emotional memories about an earlier assault that took place in a crowded area. Avoidance can come in many forms. When people can’t tolerate strong affects associated with traumatic memories, they avoid, project, deny, or distort their trauma-related emotional and cognitive experiences. A key ingredient in trauma recovery is learning to manage triggers, memories, and emotions without avoidance—in essence, becoming desensitized to traumatic memories and associated symptoms.

Differences between ASD and PTSD

It is important to consider the differences between ASD and PTSD when forming a diagnostic impression. The primary difference is the amount of time the symptoms have been present. ASD resolves 2 days to 4 weeks after an event, whereas PTSD continues beyond the 4-week period. The diagnosis of ASD can change to a diagnosis of PTSD if the condition is noted within the first 4 weeks after the event, but the symptoms persist past 4 weeks.

ASD also differs from PTSD in that the ASD diagnosis requires 9 out of 14 symptoms from five categories, including intrusion, negative mood, dissociation, avoidance, and arousal. These symptoms can occur at the time of the trauma or in the following month. Studies indicate that dissociation at the time of trauma is a good predictor of subsequent PTSD, so the inclusion of dissociative symptoms makes it more likely that those who develop ASD will later be diagnosed with PTSD (Bryant & Harvey, 2000). Additionally, ASD is a transient disorder, meaning that it is present in a person’s life for a relatively short time and then passes. In contrast, PTSD typically becomes a primary feature of an individual’s life. Over a lengthy period, PTSD can have profound effects on clients’ perceptions of safety, their sense of hope for the future, their relationships with others, their physical health, the appearance of psychiatric symptoms, and their patterns of substance use and abuse.

There are common symptoms between PTSD and ASD, and untreated ASD is a possible predisposing factor to PTSD, but it is unknown whether most people with ASD are likely to develop PTSD. There is some suggestion that, as with PTSD, ASD is more prevalent in women than in men (Bryant & Harvey, 2003). However, many people with PTSD do not have a diagnosis or recall a history of acute stress symptoms before seeking treatment for or receiving a diagnosis of PTSD.

Effective interventions for ASD can significantly reduce the possibility of the subsequent development of PTSD. Effective treatment of ASD can also reduce the incidence of other co-occurring problems, such as depression, anxiety, dissociative disorders, and compulsive behaviors (Bryant & Harvey, 2000). Intervention for ASD also helps the individual develop coping skills that can effectively prevent the recurrence of ASD after later traumas.

Although predictive science for ASD and PTSD will continue to evolve, both disorders are associated with increased substance use and mental disorders and increased risk of relapse; therefore, effective screening for ASD and PTSD is important for all clients with these disorders. Individuals in early recovery—lacking well-practiced coping skills, lacking environmental supports, and already operating at high levels of anxiety—are particularly susceptible to ASD. Events that would not normally be disabling can produce symptoms of intense helplessness and fear, numbing and depersonalization, disabling anxiety, and an inability to handle normal life events. Counselors should be able to recognize ASD and treat it rather than attributing the symptoms to a client’s lack of motivation to change, being “dry drunk” (for those in substance abuse recovery), or being manipulative.

Posttraumatic stress disorder: Timing of symptoms

Although symptoms of PTSD usually begin within 3 months of a trauma in adulthood, there can be a delay of months or even years before symptoms appear for some people. Some people may have minimal symptoms after a trauma but then experience a crisis later in life. Trauma symptoms can appear suddenly, even without conscious memory of the original trauma or without any overt provocation. Survivors of abuse in childhood can have a delayed response triggered by something that happens to them as adults. For example, seeing a movie about child abuse can trigger symptoms related to the trauma. Other triggers include returning to the scene of the trauma, being reminded of it in some other way, or noting the anniversary of an event. Likewise, combat veterans and survivors of community-wide disasters may seem to be coping well shortly after a trauma, only to have symptoms emerge later when their life situations seem to have stabilized. Some clients in substance abuse recovery only begin to experience trauma symptoms when they maintain abstinence for some time. As individuals decrease tension-reducing or self-medicating behaviors, trauma memories and symptoms can emerge.

Culture and posttraumatic stress

Although research is limited across cultures, PTSD has been observed in Southeast Asian, South American, Middle Eastern, and Native American survivors (Osterman & de Jong, 2007; Wilson & Tang, 2007). As Stamm and Friedman (2000) point out, however, simply observing PTSD does not mean that it is the “best conceptual tool for characterizing post-traumatic distress among non-Western individuals” (p. 73). In fact, many trauma-related symptoms from other cultures do not fit the DSM-5 criteria. These include somatic and psychological symptoms and beliefs about the origins and nature of traumatic events. Moreover, religious and spiritual beliefs can affect how a survivor experiences a traumatic event and whether he or she reports the distress. For example, in societies where attitudes toward karma and the glorification of war veterans are predominant, it is harder for war veterans to come forward and disclose that they are emotionally overwhelmed or struggling. It would be perceived as inappropriate and possibly demoralizing to focus on the emotional distress that he or she still bears. (For a review of cultural competence in treating trauma, refer to Brown, 2008.)

Methods for measuring PTSD are also culturally specific. As part of a project begun in 1972, the World Health Organization (WHO) and the National Institutes of Health (NIH) embarked on a joint study to test the cross-cultural applicability of classification systems for various diagnoses. WHO and NIH identified apparently universal factors of psychological disorders and developed specific instruments to measure them. These instruments, the Composite International Diagnostic Interview and the Schedules for Clinical Assessment in Neuropsychiatry, include certain criteria from the DSM (Fourth Edition, Text Revision; APA, 2000a) as well as criteria from the International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD-10; Exhibit 1.3-5).

Exhibit 1.3-5

ICD-10 Diagnostic Criteria for PTSD. The patient must have been exposed to a stressful event or situation (either brief or long-lasting) of exceptionally threatening or catastrophic nature, which would be likely to cause pervasive distress in almost anyone. (more...)

Complex trauma and complex traumatic stress

When individuals experience multiple traumas, prolonged and repeated trauma during childhood, or repetitive trauma in the context of significant interpersonal relationships, their reactions to trauma have unique characteristics (Herman, 1992). This unique constellation of reactions, called complex traumatic stress, is not recognized diagnostically in the DSM-5, but theoretical discussions and research have begun to highlight the similarities and differences in symptoms of posttraumatic stress versus complex traumatic stress (Courtois & Ford, 2009). Often, the symptoms generated from complex trauma do not fully match PTSD criteria and exceed the severity of PTSD. Overall, literature reflects that PTSD criteria or subthreshold symptoms do not fully account for the persistent and more impairing clinical presentation of complex trauma. Even though current research in the study of traumatology is prolific, it is still in the early stages of development. The idea that there may be more diagnostic variations or subtypes is forthcoming, and this will likely pave the way for more client-matching interventions to better serve those individuals who have been repeatedly exposed to multiple, early childhood, and/or interpersonal traumas.

Timeframe: PTSD and the onset of substance use disorders

Knowing whether substance abuse or PTSD came first informs whether a causal relationship exists, but learning this requires thorough assessment of clients and access to complete data on PTSD; substance use, abuse, and dependence; and the onset of each. Much current research focuses solely on the age of onset of substance use (not abuse), so determining causal relationships can be difficult. The relationship between PTSD and substance use disorders is thought to be bidirectional and cyclical: substance use increases trauma risk, and exposure to trauma escalates substance use to manage trauma-related symptoms. Three other causal pathways described by Chilcoat and Breslau’s seminal work (1998) further explain the relationship between PTSD and substance use disorders:

1. The “self-medication” hypothesis suggests that clients with PTSD use substances to manage PTSD symptoms (e.g., intrusive memories, physical arousal). Substances such as alcohol, cocaine, barbiturates, opioids, and amphetamines are frequently abused in attempts to relieve or numb emotional pain or to forget the event.
2. The “high-risk” hypothesis states that drug and alcohol use places people who use substances in high-risk situations that increase their chances of being exposed to events that lead to PTSD.
3. The “susceptibility” hypothesis suggests that people who use substances are more susceptible to developing PTSD after exposure to trauma than people who do not. Increased vulnerability may result from failure to develop effective stress management strategies, changes in brain chemistry, or damage to neurophysiological systems due to extensive substance use.

PTSD and substance abuse treatment

PTSD can limit progress in substance abuse recovery, increase the potential for relapse, and complicate a client’s ability to achieve success in various life areas. Each disorder can mask or hide the symptoms of the other, and both need to be assessed and treated if the individual is to have a full recovery. There is a risk of misinterpreting trauma-related symptoms in substance abuse treatment settings. For example, avoidance symptoms in an individual with PTSD can be misinterpreted as lack of motivation or unwillingness to engage in substance abuse treatment; a counselor’s efforts to address substance abuse–related behaviors in early recovery can likewise provoke an exaggerated response from a trauma survivor who has profound traumatic experiences of being trapped and controlled. Exhibit 1.3-6 lists important facts about PTSD and substance use disorders for counselors.

Exhibit 1.3-6

PTSD and Substance Use Disorders: Important Treatment Facts. PTSD is one of the most common co-occurring mental disorders found in clients in substance abuse treatment (CSAT, 2005c). People in treatment for PTSD tend to abuse a wide range of substances, (more...)

Sleep, PTSD, and substance use

Many people have trouble getting to sleep and/or staying asleep after a traumatic event; consequently, some have a drink or two to help them fall asleep. Unfortunately, any initially helpful effects are likely not only to wane quickly, but also to incur a negative rebound effect. When someone uses a substance before going to bed, “sleep becomes lighter and more easily disrupted,” and rapid eye movement sleep (REM) “increases, with an associated increase in dreams and nightmares,” as the effects wear off (Auerbach, 2003, p. 1185).

People with alcohol dependence report multiple types of sleep disturbances over time, and it is not unusual for clients to report that they cannot fall asleep without first having a drink. Both REM and slow wave sleep are reduced in clients with alcohol dependence, which is also associated with an increase in the amount of time it takes before sleep occurs, decreased overall sleep time, more nightmares, and reduced sleep efficiency. Sleep during withdrawal is “frequently marked by severe insomnia and sleep fragmentation…a loss of restful sleep and feelings of daytime fatigue. Nightmares and vivid dreams are not uncommon” (Auerbach, 2003, pp. 1185–1186).

Confounding changes in the biology of sleep that occur in clients with PTSD and substance use disorders often add to the problems of recovery. Sleep can fail to return to normal for months or even years after abstinence, and the persistence of sleep disruptions appears related to the likelihood of relapse. Of particular clinical importance is the vicious cycle that can also begin during “slips”; relapse initially improves sleep, but continued drinking leads to sleep disruption. This cycle of initial reduction of an unpleasant symptom, which only ends up exacerbating the process as a whole, can take place for clients with PTSD as well as for clients with substance use disorders. There are effective cognitive–behavioral therapies and nonaddictive pharmacological interventions for sleep difficulties.
