OPERATIONALIZING THE CONCEPT OF TRAUMA IN CHILDREN

Robert Pynoos (University of California, Los Angeles) discussed ways of operationalizing the cess of exposure to potentially traumatic events and the assessment of posttraumatic stress reactions in children. He began by saying that the arroyo to collecting data on these topics in children has evolved differently from the data collection approaches in adults. Unlike for adults and adolescents, at that place is no checklist of potentially traumatic events for children. In addition, the literature of trauma in children is much more nuanced and focused on details, such as age of onset, duration, and serial or sequential occurrence.

Pynoos described the SAMHSA-supported National Child Traumatic Stress Network (NCTSN), coordinated by the University of California, Los Angeles (UCLA) and Duke University National Center for Child Traumatic Stress. The NCTSN uses the UCLA PTSD Reaction Index for the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5), including the Trauma History Profile, as function of their core dataset. The scale includes 23 individual traumatic issue types. Pynoos noted that clinical studies of children testify that witnessing a parent's rape produces levels of PTSD that are substantially equivalent to being sexually abused. A threat to a parent or sibling is considered to be one of the elements of feeling life threat among children. Because of this, the scales for children include a category for direct victimization and a separate category for existence a witness.

Pynoos said that the literature on trauma in children likewise differs from the literature on trauma in adults in the way information technology addresses issues related to bereavement and the coaction of trauma and grief reactions. A relatively higher proportion of the deaths experienced past children occur under traumatic circumstances compared to the deaths experienced past adults. I case is the sudden expiry of a principal caregiver amidst young children.

One of the points underscored past Pynoos was that in psychiatric epidemiological studies it may exist important to oversample children with insufficiently rare, but high magnitude exposures. This could include children who witnessed homicide or the rape of a parent in lodge to evaluate severity of touch on and consequence. This approach is like to the study of rare medical conditions among populations.

Pynoos said that it is important to be mindful of the developmental epidemiology of exposure. Exposure to sure types of traumatic events is more probable at certain ages, and the profile of the effect changes depending on age. Some events are more likely to co-occur amid children, especially in early babyhood. For example witnessing domestic violence, physical abuse, psychological maltreatment, neglect, and dumb care-giving can form a constellation of early on childhood exposures. In addition these same conditions often are associated with lack of supervision and increased chance for dog bites, serious burns, and near drownings. The literature focused on trauma in adults rarely takes account of this co-occurrence when discussing early babyhood exposure. These items are important to include in order to sympathise the full context of trauma history.

The exposure configuration changes in adolescence. Beingness a driver or passenger in a fatal car accident, witnessing gang rape, criminal victimization, and trafficking become more than relevant. In addition, the adolescent experience is non the aforementioned every bit that of a younger child either. For instance, being an adolescent commuter or passenger in a auto accident is different from existence in a car accident while being driven to school past a parent.

Pynoos said that the risk of exposure specific to different events increases at dissimilar points over the life course. Thus, information technology is useful to call back about the developmental epidemiology of exposure, rather than just thinking of a list of events. Researchers have also observed a "risk caravan," meaning what additional risks are accrued with the accumulation of dissimilar types of exposures.

Figure 4-1 shows the differences in the pattern of trauma types in early childhood, school age, and adolescence, based on data nerveless by the NCTSN. Pynoos said that the data are non from a nationally representative sample, but they testify informative differences based on a large-scale (North = 19,088) database of children and adolescents receiving services in the U.s..

Based on the NCTSN data, Pynoos and his colleagues have been able to isolate cases of merely emotional corruption in early childhood, and examine its effects in relation to its own characteristics and as a component of the early childhood constellation. They learned that emotional abuse under age 6 produces similar levels of PTSD as other traumatic events, perhaps considering emotional abuse, such as threats of abandonment, is experienced by children every bit a life threat.

Pynoos said that the data also show how exposures to several different events work together. Emotional abuse has an condiment result when co-occurring with physical corruption, neglect, and witnessing domestic violence. In improver, symptom profiles may modify as exposures occur beyond developmental periods. For instance, when babyhood sexual abuse is added to other early on exposures, the symptom profile is dominated past posttraumatic stress relations related to the sexual abuse, maybe masking some of the other trauma-related reactions. The data also show a cascade of effects for exposure: sexual abuse at age half dozen increases the risk of sexual assault past historic period 9. Through childhood and into adolescence, the risk for other bug that SAMHSA is interested in also tends to accumulate, including drug abuse, HIV, and various risky behaviors, representing a caravan of risk. Pynoos commented that this finding too means that it is possible to identify the many different points where ane can intervene and possibly forestall the emergence of the next risk factor.

In terms of the debate nearly the advantages of a systematic review of trauma exposure in comparing with request gateway questions, Pynoos said that in his piece of work he benchmarks exposures against developmental periods, rather than asking about lifetime exposure. His method involves providing blocks of time that respondents can utilise to reference their experiences: for case, when you were niggling, earlier you went to schoolhouse, in elementary school, in junior loftier school, or in high school. This arroyo can increase the reliability of responses in children and adolescents.

In the case of adolescents with exposure to multiple events, Pynoos said that he and his colleagues ask respondents to construct a bureaucracy of events by ranking them and so indicating which ones are the most disturbing to them in their current lives. Sometimes they ask respondents to construct two hierarchies, one for childhood and one for adolescence, because research shows that adolescents mentally split off their boyish experiences from their younger experiences. The responses are ofttimes unexpected: for example, when an boyish ranks continuing at a bus stop when he was 13 and seeing a man brutally beating his wife equally more than intrusive than a contempo experience of being in a shooting.

Pynoos said that children down to the age of 8 tin can reliably cocky-written report and provide comparisons to evaluations using structured interviews, such as the Clinician-Administered PTSD Calibration (CAPS) and the child version of the Schedule for Affective Disorders and Schizophrenia. Children can be accurate reporters if the questions are phrased carefully with developmentally appropriate wording, and if they are adequately tested. However, at that place are certain types of information that children are non very good at reporting. For example, some of the typical gateway questions about upsetting memories and flashbacks practice not piece of work well in children. Some of those information, such as reports of restless, agitated sleep, tin exist nerveless with better accuracy from the parents. In add-on, the historic period vi and younger criteria for PTSD in DSM-5 notes that children can take repetitive play, re-enactment behavior, and intrusions without overt signs of distress.

In terms of criteria C, Pynoos said that the lack of endorsement of avoidance symptoms is one of the main reasons why children practise not meet diagnostic criteria for PTSD. For example, children are typically unable to describe "feeling numb." The challenge with asking about abstention is that children do non often have a choice for physical abstention. In the DSM-five, the wording was changed to "efforts to avert" and associated behaviors are included, such as a child throwing a tantrum when the parents want to have her or him somewhere that might serve as a reminder of a traumatic event. When information technology comes to avoidance, children are more likely to endorse the "practise non want to talk near information technology" response option. Among category Due east symptoms, sleep disturbance is important, specially because in a young child information technology can have an enormous bear upon on learning.

Pynoos reiterated that the symptom profile can change as children become older. For example, in some of the studies of New York City schoolhouse children, conducted in the aftermath of 9/11, school-historic period children tended to report efforts to avoid, while adolescents did and so less frequently, instead describing other problematic behaviors.

In terms of the transition to the DSM-five, Pynoos noted that the UCLA PTSD Reaction Index Trauma History Profile and the CAPS for children and adolescents are available. These now include diction for the new symptom items D and E (see Chapter 2), including negative emotions, such equally guilt and shame, which require developmentally appropriate wording. They besides include child-specific items for other trauma-related expectations, and child and boyish worded questions nearly irritable and ambitious beliefs, and reckless or self-destructive behavior. Pynoos emphasized that information technology is very important to thoroughly test these types of items.

1 of the challenges raised by Pynoos is related to formulating questions for adolescents about current PTSD when the traumatic event happened before the age of half dozen. The criteria for children vi and nether are different from the criteria for those who are older. Deciding which criteria to use is non immediately obvious. Pynoos said that asking virtually dissociative subtype is particularly hard, but testify suggests its importance even among immature children.

In society to establish symptom presence, Pynoos and his colleagues employ pictorial tools as anchors. For case, to get reliable frequency in days per calendar month, they use a calendar that illustrates each answer pick. To collect data on caste of intensity and decide how much the symptoms bother respondents, they use pictures of spectacles filled to various levels. Pynoos believes that this technique leads to more reliable reporting in the case of children and adolescents than using verbal labels alone.

A question that has not still been settled in the context of the DSM-v is that of the cutoffs for counting a symptom equally present. A cutoff is needed fifty-fifty in the case of a continuous scale if the goal is to get in at a determination that is a diagnostic probability. Pynoos said that he and his colleagues have a study in progress to help reply this question. Another outstanding question noted past Pynoos is the extent to which a proxy symptom question for some level of lifetime PTSD would work in children and adolescents.

Pynoos also discussed the concept of functional impairment, a key benchmark of PTSD in the DSM-5. The text of the DSM-5 provides a developmental framework regarding functional impairment, including in schoolhouse and among peers. In immature children, avoidant behavior may lead to restricted play or exploratory behavior; in adolescents, it may lead to reduced participation in new activities or missed developmental opportunities, such as dating and learning to drive. Pynoos emphasized that developmental outcomes need to exist considered along with what has typically been considered to be functional impairment. For example, studies accept shown that sexual abuse in childhood can atomic number 82 to diminished self-care in adulthood. Such behavior is not a functional effect the fashion it is ordinarily defined, but as a developmental event it has profound influences on wellness behavior. In contrast to developmental delays, adolescents may show developmental accelerations every bit an outcome of traumatic experiences that increase the risk of further exposure.

NCTSN data prove that among adolescents that take had multiple traumas earlier in babyhood, in that location is a substantial subgroup that has subclinical levels of PTSD that are associated with major functional impairments. In improver, children and adolescents who meet only criteria B and D can take meaning functional damage, and different clusters of symptoms may have different causal relations to outcomes (for instance, risk behavior, health consequences). He noted that if a study design calls for skipping some items, information technology could mean skipping the ones that would otherwise be the most highly endorsed by respondents.

Research on comorbidity has shown some interesting patterns in children and adolescents. For instance, studies on the backwash of disasters and terrorist attacks, such as 9/11, have found increased separation anxiety disorder in adolescents, which is not typically expected in that age grouping. Pynoos emphasized that in examining issues such as substance corruption in adolescents, it is important not to overlook exposure to death as a possible contributing gene. When bereavement leads to substance abuse, the associated behaviors are ameliorate understood in adults, and they need to exist further studied in adolescents. He and his colleagues developed the Persistent Complex Bereavement Disorder Checklist for utilise in clinical research.

Finally, Pynoos said, another specially important issue is multiple comorbid conditions amid adolescents with complex trauma histories. A new diagnosis that has been proposed by a collaborative group of the NCTSN is developmental trauma disorder that gives priority to disturbances in development.

MEASUREMENT AND IMPLEMENTATION CONSIDERATIONS FOR COLLECTING Data ON TRAUMA IN CHILDREN

Benjamin Saunders (Medical Academy of South Carolina) discussed the measurement of potentially traumatic events and PTSD in children, with specific focus on implementation considerations. He agreed with Pynoos that the near difficult cases to measure and treat involve children who accept been exposed to multiple traumatic events. He added that there are events that tin be potentially traumatic to children, but would non be similarly traumatic to adults, or even adolescents, so the developmental aspects of what may or may non be traumatic based on historic period is something that is important to consider when deciding what needs to be measured. In addition, asking an adult well-nigh things that are meaningfully important to them at the present that were potentially traumatic when they were children could issue in a list that does not stand for to the types of events that are included amidst the DSM-v criterion A events (see Chapter 2).

Starting with the premise that no single study can mensurate everything related to potentially traumatic events, PTSD, and related outcomes, Saunders discussed several strategies for narrowing down the list of items to those that are key to include in a particular study. Starting with reviewing the prevalence rates in the population for specific traumatic events would be a reasonable approach. Another useful initial step would be reviewing existing data on bear on, in other words, the percentage of people with a certain type of experience who develop PTSD or the pct of people who have PTSD equally a consequence of the experience. He noted that some events, such every bit sexual set on, are included in almost all data collection instruments on the topic because of the wide understanding about their potentially traumatic nature.

In some cases, a detail topic may be of interest for a specific study or become more relevant due to current events generally. An example is sexually exploited children: xv years ago, it was not a topic that was typically assessed in data collections on trauma, but it is at present almost always included because of the increased visibility of the outcome.

Saunders commented that Schell'southward give-and-take (see Chapter three) almost formative scales and the idea of identifying the outcomes of interest earlier the relevant traumatic events was useful. That approach could reduce the likelihood of items being introduced but because they happen to be of involvement to someone at a particular moment or are subjectively considered potentially more traumatic than others past particular researchers.

Beyond measuring potentially traumatic events, agreement the incident characteristics, the context of the issue or events, and other background information near respondents can also be disquisitional because they are often associated with the evolution of PTSD. Robert Ursano (Uniformed Services Academy of the Health Sciences) mentioned the importance of understanding the community context, and Saunders pointed out that geocoding may exist useful to add to data collection. Other data that are typically collected as function of studies on the topic of trauma include whether the event was a single effect or function of a series of events, the duration of the issue, and the respondent's historic period when the event first happened and when it stopped. In the case of children, in item, traumatic events are often repeated incidents.

Saunders underscored the importance of agreement trajectories and the sequence of exposure that leads to increasingly more risky beliefs, a topic that was besides discussed by other speakers. He said that understanding the neurobiological and sociological processes involved and the reasons why some children develop difficulties and others do not are currently the about promising areas of research in the field of trauma. He pointed out that the circuitous interactions among events, outcomes, mediators, and moderators tin exist particularly difficult to tease autonomously with data from large national surveys, and it is not clear to what extent is it possible for SAMHSA to undertake a large-scale project, but he argued that examining these problems would move the field forwards. Still, he warned that even a hypothetical report that had unlimited resources would be challenged in developing an approach that would come close to fully capturing all the relevant data. The nature of the topic is such that there will always be a river of possible alternative explanations for outcomes running below the data.

An of import consideration when collecting data about trauma in children is that if children are interviewed, permission from their parents is required. And for some age groups, parent interviews need to be substituted for the interviews with children. Researchers have to decide when information technology makes sense to interview a child, said Saunders. In some cases, parent interviews can produce reasonably good information, and interviewing parents may be more than efficient if they need to be contacted to obtain permission.

Saunders summarized the characteristics of a good screening approach:

• includes multiple questions covering the range of experiences within type;

• assures that items are behaviorally specific to reduce interpretation;

• uses language level consistent with the target age group;

• cues retrievable memories of past events; and

• matches respondents' interpretations and labeling of experiences.

He pointed out that the concluding particular on the list (assuring that the questions friction match a respondent's interpretation and labeling of experiences) is the nearly challenging in the context of interviewing children. Researchers need to develop questions with language that corresponds to the schema used by children and their views of the experiences.

Saunders said he agreed with Terrence Keane (Boston University Schoolhouse of Medicine and U.S. Department of Veterans Affairs National Center for Posttraumatic Stress Disorder) that questions on this topic are very susceptible to society effects and that the sequence of the sections also deserves careful attention. In his research, Saunders said, he likes to begin with easy questions, followed by the sensitive questions, and then another ready of easy questions, which may be followed past a debriefing.

Some of the common errors he noticed in instruments on this topic include

• not asking key questions;

• "gate" questions and single screening items;

• undefined terms that are open to significant estimation past respondents (eastward.g., physically driveling, sexually abused, fondled, bullied, raped, molested, attempted, domestic violence);

• double- (or more) barreled questions;

• lengthy or overly wordy questions; and

• asking follow-upward questions afterwards each screening hit.

Questions with the shortcomings highlighted higher up can exist especially difficult for children and adolescents and can lead to college error rates in some age groups. For example, questions that are open up to estimation or are lengthy tin can nowadays more challenges for children than for adults. Asking follow-upwards questions after each screening hit can lead to response bias in any age grouping, if information technology cues respondents that a "yep" reply will lead to more follow-up questions, and they begin altering their responses equally a result.

Saunders also listed several factors that can touch case detection:

• level of perceived confidentiality offered, concerns of getting self or others in trouble, fear of retribution;

• context of the screening setting

  –

  location of respondent (home, school, other)

  –

  method (in-person, group, telephone, paper, computer)

  –

  who is present? (interviewer, parents, teacher, peers, siblings);

• think of events by respondents

  –

  experiences non recalled, forgotten, and not accessible

  –

  experiences partially forgotten, just retrievable with the right cuing

  –

  remembered experiences, but not divers by the respondent in the aforementioned way equally the screening question is worded

  –

  remembered experiences that are willfully withheld; and

  willful nondisclosure.

Saunders said that perceived confidentiality is a particularly important consideration when interviewing children because they tend not to sympathise or believe that the information they provide will exist kept confidential. A related issue is willful nondisclosure. While adults can also be reluctant to talk about traumatic events, such reluctance is more common amongst children and adolescents. The reasons for this may be in function that, for children, the questions are more than likely to be about something that happened in the recent past rather than an outcome that happened decades ago in the case of adults. Children may have had less time to procedure the event and develop a perspective on it.

Other reasons for willful nondisclosure include

• sense of stigma, shame, guilt, self-blame;

• threats or instructions by a parents;

• fear of punishment, "getting into trouble";

• fear of consequences to family unit and family members;

• cultural and familial behavior about privacy;

• psychological distress nearly events;

• fright of retribution by assailant; and

• history of negative outcomes from prior disclosures (disclosure inoculation).

Saunders said that a history of negative outcomes from prior disclosure tin be peculiarly challenging to overcome. Some children may be "inoculated" against talking about what happened to them considering they had tried to talk about it before and bad things happened, or nothing happened. Conscientious question diction can aid reduce some of these challenges.

Saunders noted that at that place are several upstanding questions that arise in the context of research on trauma about children. One question is whether the interviews will exist overly distressing. He said that he and his colleagues, as well as other groups of researchers, have conducted studies to examine this consequence and concluded that the interviews practice not appear to be overly distressing. Even so, less is known about the reactions of younger children than about adolescents.

Another question that comes up is whether the parents get upset when they larn about the types of questions that are being asked of their children. Saunders said that some parents practise accept objections, and it is important to think through the concerns they might take prior to contacting them.

A related upshot is whether request the questions could place some children at take chances from their parents. Saunders said that their longitudinal studies seem to advise that this is not the case because they found that children with trauma histories are more likely to participate in the follow-up waves of the studies, after the initial interview, than children without trauma histories. This finding could exist an indication that these children did not feel any repercussions later participating and that they institute the caption and data provided to them equally part of the study helpful.

Saunders also pointed out that collecting data virtually trauma in children means collecting information that can take legal implications. He said that it is important to carefully consider how the identifying information is stored and who has access to it, as well equally whether the data can be subpoenaed. There are also mandatory reporting laws that may apply, and these can be dissimilar by state, then a plan is needed for how to manage situations in which this result may arise. Saunders said that he and his colleagues likewise use a "child in danger" protocol, like to what SAMHSA used in the Mental Health Surveillance Report, and it seems to piece of work well.

Graham Kalton (Westat) asked whether there are means to deal with situations in which a parent is abusing the child and and then does not grant permission for the interview. Saunders said that this is likely happening and that the nigh one can practice is to develop survey materials that reduce this problem equally much equally possible. He acknowledged that it is likely that this leads to underestimates of kid trauma in all surveys. However, he noted that in his studies usually less than 10 percentage of parents decline to have their children interviewed after the parent interview is completed. Schell noted that some of the phenomena that are being measured are very rare in the population, and then refusals can make a big deviation. Pynoos added that an boosted issue with the proliferation of cell phones is that survey researchers are less likely to be calling a landline and then beingness able to continue the interview with the child, on the same line, later obtaining permission from the parent. The fact that most people and many children have their own cell phones complicates the data collection procedure.

Kilpatrick commented that if the survey is about a variety of topics, researchers exercise non need to begin the conversation by saying that they would similar to ask children about whether they had been abused. For example, 1 of their studies, the National Survey of Adolescents, was about a range of topics that are important to parents and families, such every bit customs violence and alcohol and drug use. He said that it is important to provide an accurate description of what the study is about, only providing also many specifics tin can increase nonresponse bias.

Kalton said that it has been noted that child reports ofttimes differ from parent reports and that some studies that include teacher reports detect that the teacher reports are besides very different. Some researchers argue that multiple reports are necessary to measure issues of this type. Saunders agreed that there are typically significant differences in what is reported, depending on who is providing the data, and that this is generally the case with topics of this blazon. He noted that, in some sense, all of these reports may exist accurate from the perspective of the person who is reporting. There is typically more than convergence in data about child beliefs than about internalizing bug, such as depression or PTSD, which definitely represents an analytic challenge. Pynoos commented that the topic of trauma presents special challenges in this regard because the link betwixt traumatic exposure and behavior is rarely identified by parents and fifty-fifty less often by the schools.

James Jackson (University of Michigan) asked Saunders to clarify why he thinks that children and adolescents are more skeptical of promises of confidentiality. Saunders said that many children are afraid of consequences, such equally getting into problem or getting someone else into problem. Disarming them that what they say will exist kept confidential is especially hard if, equally office of the informed consent process, they are also told that in some cases what they say may have to be reported (e.g., in mandated reporting situations). He reiterated that very conscientious wording is crucial. Jackson said that his own enquiry with adolescents leads him to think that adolescents are skeptical almost adults' ability to "keep secrets," which is a small, but important distinction, and that agreement these nuances is crucial in society to be able to address the concerns. Pynoos commented that his inquiry indicates that adolescents are more likely to disclose exposure to traumatic events when the questions are administered by calculator rather than in person.
