ustody dispute, and made more changes in their children’s living arrangements over the years (Emery, Laumann-Billings, Waldron, Sbarra, & Dillon, 2001). Moreover, increased contact between parents did not lead to heightened coparenting conflict. Research has resulted in conflicting findings regarding the importance of children’s contact with their father. For exam- ple, large-scale national studies have generally found no rela- tionship between frequency of father contact and children’s postdivorce adjustment (Kelly, 2000). However, in a meta- analysis of 57 studies, Amato and Gilbreth (1999) found that more recent studies of father-child contact provide stronger evidence of father impact on child adjustment than do earlier studies. Again, the quality of the relationship (e.g., feelings of 202 Child Custody Evaluation closeness with the child and active parenting of the father) is more important than frequency of visits. The degree to which father involvement impacts child adjustment, however, ultimately is linked to such factors as degree of conflict, type of paternal and maternal acceptance, and regular pay- ment of child support (Lamb, 1999; McLanahan & Sandefur, 1994; Pruett & Pruett, 1998). Furthermore, one group of researchers reported that even when economic factors were accounted for, children in father-custody families evi- denced fewer problems than those in mother-headed families (Clark-Stewart & Hayward, 1996). Nevertheless, while “fathers are important…children can develop well in mother-headed families with absent fathers” (Hetherington & Stanely-Hagan, 1999, p. 136). Type of Custody Arrangements At a theoretical level, substantial debate remains about which custody arrangement is in the best interests of children. Besides the benefits and detriments to each parent (and how they indirectly affect a child), effects on the child with regard to single-parent versus joint-custody arrangements are mixed. On the one hand, advocates of joint-custody argue that children are expected to experience both higher quality residential parenting and relationships with nonresidential parents, more cooperative coparenting, and ultimately, better adjustment (Emery et al., 2001; Gunnoe & Braver, 2001). Conversely, critics are concerned that joint custody exacer- bates family conflict by requiring sustained contact to col- laborate in the child’s interests and that children will be adversely affected when they are unable to keep their rela- tionships with both parents equal (Gunnoe & Braver, 2001). Moreover, results of research on the adjustment of children from single-parent versus joint custody families also have been mixed. For example, Johnston (1995) asserts that more recent and larger studies find few differences in adjustment between children in sole versus joint physical custody, other than higher parental income and education and regular child support payments among joint custody parents. Conversely, Kelly (2000) notes that joint legal custody has been linked to children’s well-being. Yet others have speculated a more complex relationship between type of custody arrangement and adjustment. For example, Gunnoe and Braver (2001) identified 20 variables that predisposed families to be awarded either sole or joint custody, including demographic factors (e.g., education of mother, hours per week worked by father), parental adjustment (e.g., fathers’ anger), spousal relations (e.g., mothers’ visitation opposition), aspects of both fathers’ parenting (e.g., involvement in child rearing, visitation during separation) and mothers’ parenting (e.g., rejection/acceptance of child), and child adjustment (e.g., male children’s antisocial behavior, impulsivity). After controlling for these factors, which were hypothesized to have confounded apparent effects obtained in previous re- search, results indicated that families with joint custody had more frequent father-child visitation, lower maternal satis- faction with custody arrangement, and more rapid mater- nal re-partnering. All in all, however, children tended to exhibit fewer adjustment problems. Moreover, Maccoby and Mnookin (1992) reported that when conflict was low after di- vorce, adolescents in joint physical custody were better ad- justed, but not in high-conflict postdivorce families . Finally, in families with extreme and continuing high conflict after di- vorce, children (particularly girls) with more frequent transi- tions and shared access were found to have more emotional and behavioral problems than children in sole custody situa- tions (Johnston, 1995). Thus, it appears that interparental conflict continues to be a pivotal factor in children’s adjust- ment well after the marriage has been dissolved. The type of custody arrangement and its likely effects cannot be consid- ered in isolation. SUMMARY Child custody evaluations are one of the most difficult areas of forensic practice, given the complexity of the issues at hand (e.g., vague legal doctrines, contentious family dynam- ics, multiple persons and domains requiring assessment) and the intrinsically tenuous nature of any empirically supported conclusions that examiners reasonably can be expected to draw in most cases. Despite these difficulties, it seems clear from the preceding review that significant improvements in the child custody arena have been made in recent years. These improvements can be seen in the ever-expanding data- base of empirical research concerning the relationship be- tween parenting behavior and child adjustment, the effects of divorce, and the impact of various custody arrangements on children. Improvements also can be seen in terms of the de- velopment of professional guidelines promulgated by various organizations that provide at least some instruction about standards of practice for examiners. Despite these advances, considerable room for improve- ment remains in most areas of research and practice, and sig- nificant problem areas should be noted (see also Nicholson & Norwood, 2000). First, the existing assessment approaches employed by many examiners remain of questionable value for assessing the psycholegal constructs relevant to child custody issues. Moreover, the recent advent of “custody- specific” tests in particular could be argued to be a step References 203 backward in the process of developing appropriate instru- mentation. Second, the scientific foundation on which exam- iners should draw their conclusions and/or recommendations, although considerably improved, remains in its infancy. Fur- thermore, research in this area always will be constrained by the inability to use true experimental designs to address the most prominent questions related to custody decision making. Additionally, little is known about how child custody evalua- tors, attorneys, and judges consider information in cases, and on what types of information they base their decisions. A final and more general area of concern is that many of the fundamental issues needing to be resolved in custody cases (e.g., what is in a child’s best interest) ultimately are value judgments that may not be directly amenable to scientific in- quiry, although value judgments made by legal decision mak- ers certainly can be informed by scientific data (as noted previously). Some of the more damning critiques of this area of practice assert that it is little more than subjective value judgment dressed up as expert opinion or social science data. In fact, there remains a debate within the field about the fun- damental appropriateness of the involvement of mental health professionals in child custody evaluations (Emery, 1999; Koocher, 1999; Melton, 1999; O’Donohue & Bradley, 1999; Weisz, 1999). Despite this debate, it is clear that mental health professionals will continue to be involved in these evaluations for the foreseeable future. As such, attention to improving the quality of practice in this area should remain a priority. REFERENCES Abidin, R. R. (1995). Parenting Stress Index. (PSI).

Along with this has been an increasing recognition that children may experience a variety of psycho- logical reactions, including posttraumatic stress disorder (Pynoos, Steinberg, & Goenjian, 1996; Shannon, Lonigan, Finch, & Taylor, 1994). These developments, and the nature and consequences of psychological trauma, are of particular interest to both psychologists and attorneys addressing issues related to a variety psycholegal applications involving children. DEFINITIONS OF TRAUMA Trauma is discussed in the literature in various ways. Psycho- logical trauma has sometimes been described as an overwhelming experience that can result in a continuum of posttrauma adaptations and/or specific symptoms. At other times, psychologists and lawyers have interchangeably de- fined trauma as a qualitative degree of suffering within the child (an effect) or as a psychological consequence related to a forensically relevant event (a cause). The forensic psychol- ogist asked to evaluate children in such matters should be careful to avoid assumptions about the nature, extent, and causality of psychological functioning based solely on the ex- istence of a legally contested event and its presumed magni- tude of psychological disruption. Whether a child has suffered the effects of trauma that is proximally related to a legally re- lated event can be determined only after a careful analysis of multimodal data gathered within an objective forensic evalu- ation context. Melton, Petrila, Poythress, and Slobogin (1997) note that a variety of terms have been used to describe the mental effects associated with emotional distress legal cases, but the trauma-based diagnosis most likely to be involved in mental injury cases is posttraumatic stress disorder (PTSD). Impair- ment and diagnosis are both relevant to clinical treatment and prognosis. In assessing childhood trauma, concepts of I wish to thank Marc R. Stein, Esquire, and Robert Kinscherff, PhD, JD, for their very helpful review of the chapter. 210 Assessment of Childhood Trauma damage or disability should include evaluations of whether the child’s psychological problems were proximately caused by a legally relevant event. Evaluation of childhood trauma need not be limited to traditional psychiatric diagnostic clas- sifications systems, such as the Diagnostic and Statistical Manual of Mental Disorders, fourth edition ( DSM-IV; Amer- ican Psychiatric Association [APA], 1994). The DSM-IV states that the essential feature of PTSD is the development of characteristic symptoms following exposure to a situation experienced as stressful. The stressful event can involve direct personal experience that involves actual or threatened death or serious injury or other threat to one’s “physical integrity,” as well as “witnessing an event that in- volves death, injury, or a threat to the physical integrity of an- other person; or learning about unexpected or violent death, serious harm or threat of death or injury experienced by a fam- ily member or other close associate” (APA, 1994, p. 424). Historical accounts of trauma appear early in literature and are varied. For example, as cited in Pynoos et al. (1996), accounts of an adolescent’s reactions to the eruption of Mount Vesuvius are reported as early as A . D . 100–113 in the letters of Pliny the Younger (1931). Andreasen (1985) notes that the term post-traumatic stress disorder first appeared in DSM-III, but that the concept is considerably older, often found in histories of early warfare. Andreasen describes a stress syndrome in soldiers during the U.S. Civil War that was originally believed to be due to functional cardiac distur- bance. The condition of “shell-shock” during World War I was once believed to be due to organic brain syndrome sec- ondary to carbon monoxide gas. World War II gave rise to a great number of “combat neuroses” or “traumatic war neu- roses,” which led to an increased interest in PTSD, eventually resulting in a category of “gross stress reaction” in the International Classification of Diseases ( ICD; World Health Organization, 1977). The Web site of the National Institute of Mental Health Public Inquires notes that PTSD is a debilitating condition that follows a terrifying event and can occur at any age, including childhood. About 4% of the population will experience symptoms in a given year. Symptoms typically begin within three months following a traumatic event, al- though occasionally symptoms do not begin until years later. Once PTSD develops, the duration of the illness varies. The DSM-IV reports prevalence ranges from 1% to 14% because of the variability of the methods of ascertainment and sam- pling of populations. The public information Web site for the American Psychiatric Association (1999) reports that 10% of the population has been affected at some point by clini- cally diagnosable PTSD. The DSM-IV notes that duration of symptoms varies, with complete recovery occurring within three months in approximately half of cases. Andreasen (1985) notes that chronic PTSD is less common than acute, with symptoms of six months or longer. The foregoing statis- tics are not specific to children. Therefore, evaluators should appreciate that a given referral involving child trauma may represent a problem with significantly different base rates. In his manual for the Trauma Symptom Checklist for Children, Briere (1996) notes that researchers have docu- mented a wide variety of psychological effects associated with trauma.As cited by Briere, some of the effects include the mur- der of a parent (Malmquist, 1986), war (Baker, 1990; Sack, Aangel, Kinzie, & Rath, 1986; Ziv, Kruglanski, & Shulman, 1974), natural disasters such as earthquakes or hurricanes (Green et al., 1991), physical and sexual abuse (Browne & Finkelhor, 1986; Kiser, Heston, Millsap, & Pruitt, 1991; Kolko, Moser, & Weldy, 1988; Lanktree, Briere, & Zaidi, 1991), witnessing spousal abuse (Jaffe, Wolfe, & Wilson, 1990; Kashani, Daniel, Dandoy, & Holcomb, 1992), physical and sexual assaults by peers or caretakers (Boney-McCoy & Finkelhor, 1995; Freeman, Mokros, & Poznanski, 1993; Singer, Anglin, Song, & Lunghofer, 1995) as well as parental divorce or hospitalization of a family member (Evans, Briere, Boggiano, & Barrett, 1994). Studies suggest that half of all sexually abused children meet partial or full criteria for PTSD (McLeer, Deblinger, Atkins, Foa, & Ralphe, 1988; McLeer, Deblinger, Henry, & Orvashel, 1992). In addition to direct threats to children, posttraumatic stress can be experienced indirectly when children perceive threat to their major sources of psychological security. Motor vehicle accidents are considered the major cause of posttraumatic stress in the general population (Norris, 1992). Burns can result in pro- tracted and disfiguring injuries; in pediatric cases, fire and burn injuries are second only to motor vehicle accidents in children ages 1 and 4 years. Children may be traumatized not only by directly experi- encing traumatic experience, but by observing the event (Lyons, 1988). In the growing literature concerning domestic violence, children are described as being subject to serious psychological detriment from the observation or knowledge of violence in the household (Jaffe, 1995). Parent reports of the child’s history or their ratings of the child’s functioning can be distorted by downplaying the incidence of interper- sonal violence in the family or their noting the effects on the child. Classes of Psychological Trauma The range of forensically relevant referrals can be grouped into categories of noninterpersonal and interpersonal forms of trauma. Noninterpersonal forms of trauma can include burns, witnessing fires, motor vehicle accidents, floods, earth- quakes, and hurricanes, and other forms of natural disaster. Definitions of Trauma 211 Interpersonal forms of trauma can include sexual/physical abuse, witness to domestic violence or spousal murder, chronic exposure to expressed hostility in divorce conflicts, kidnapping, or shootings in school settings. One case the writer reviewed involved the scalding death of a baby in the presence of multiple siblings. In this case, there were direct and secondary traumatic effects of interpersonal origin. Not only did the children witness the death of a sibling by a parent, but they were also being considered for trial testimony in the prosecution of a parent in a death penalty case.Although each case should be analyzed without preconceptions as to whether a child is necessarily affected or to what degree, DeBellis (1997) noted that when trauma is of interpersonal origin, the resulting disorders may lead to more lasting and/or severe symptoms. Terr (1991) suggested that two classes of trauma may lead to PTSD in children. The first involves single, sudden and unexpected experiences, such as being the victim of a violent crime; the second involves repeated occurrences, often ex- pected by the victim, such as ongoing physical or sexual abuse. Repeated exposure to traumatic stressors may result in significant psychological disruption for a variety of reasons, including the child’s inability to profit from moderating vari- ables of resilience, social support, and positive coping mech- anisms. The assessment should be broad enough to examine variables beyond simply the magnitude of the stressor, as me- diating variables can significantly affect the child’s reaction to a traumatic event. DSM Diagnoses Related to Childhood Trauma Relevant DSM diagnoses include, but are not limited to, PTSD, acute stress disorder, and adjustment disorder with anxious or depressed features. Careful differential diagnosis is needed, particularly concerning mood disorders and/or attention-deficit/hyperactivity disorder (ADHD), whose clin- ical presentations can appear similar and may be comorbid with PTSD. Meyer (1993) has noted that it may be more appropriate at times to use the diagnosis of adjustment dis- order, qualified by possible features of anxious or depressed mood, disturbance of conduct, academic inhibition, mixed emotional features or mixed disturbance of emotions and conduct. This can occur when a stressor is more likely within the normal range of experience, with little in the way of a vivid reexperiencing of the event. Differential Symptomatology of Posttraumatic and Anxiety States PTSD is classified as one of the anxiety disorders. Although some features of some anxiety disorders can occur in posttraumatic states, there are a number of distinguishing characteristics. Knowledge of these differences can be im- portant when formulating opinions as to whether the symp- toms documented in the forensic evaluation are proximately caused by a legally related event or are related to a preexist- ing or coexisting disorder. For example, panic attacks can be associated features of other anxiety and psychotic disorders. Panic attacks in PTSD are cued by stimuli recalling the stres- sor, whereas panic attacks that occur in the context of other anxiety disorders are situationally bound, predisposed, or more generalized. Panic attacks in PTSD can generalize to other situations but should originate in stimuli reminiscent of the trauma before generalization. In social phobia, the panic attack is cued by social situations; in specific phobia, by a particular object or situation; and in obsessive-compulsive disorder, by exposure to the object of an obsession ( DSM-IV, APA, 1994). Anxiety as a trait has a familial association. Generalized Anxiety Disorder, which includes Overanxious Disorder of Childhood, consists of a variety of anxiety symptoms exclusive of the distinguishing posttraumatic characteristics. Acute stress disorder is a closely related diagnosis, but is appropriate only for symptoms that occur within one month of an extreme stressor. For symptoms that persist longer than one month, PTSD should be considered. For those children who experience an extreme stressor but do not meet the PTSD criteria of dissociative symptoms, persistent reexperi- ence of the traumatic event, marked avoidance of stimuli associated with the traumatic event, anxiety, or arousal, a di- agnosis of adjustment disorder should be considered. When attempting to describe the results of one’s forensic evaluation using DSM classifications, it is important to keep in mind that each descriptive term may represent connotations to judges or attorneys not consistent with their meanings and implica- tions understood by mental health professionals. For exam- ple, the term acute stress disorder may be understood to be synonymous with PTSD in terms of the severity of symptoms or how long symptoms persist. Therefore, diagnoses de- scribed in reports or during testimony should be carefully characterized and distinguished from one another. Dissociative amnesia is characterized by a difficulty in re- calling important personal information, whereas depersonal- ization can include persistent or recurrent feelings of being detached from one’s mental processes or body ( DSM-IV, APA, 1994). Dissociative amnesia can occur in PTSD and is not diagnosed when it does. Forensic evaluation of children who have experienced chronic sexual or physical abuse should consider the possibility of dissociative reactions as part of a PTSD. Evaluation of these children requires addi- tional evaluation competencies to ensure defensible inter- viewing techniques and the reliability of one’s opinions. 212 Assessment of Childhood Trauma The range of symptomatology with children is not defined by stage of development or the severity of the disorder. Eval- uators should be alert to the widest possible spectrum of man- ifestations that can differ from those found in the diagnostic criteria for PTSD. The evaluator should be knowledgeable about traumatic reactions in children and carefully assess the possible presence of such problems. Doing so not only increases the evaluator’s confidence in the conclusions, but also anticipates possible cross-examination challenges to forensic opinions. Communicating Trauma in Forensically Relevant Terms Evaluators should not rely solely on DSM diagnostic formula- tions to define forensically relevant issues. This diagnostic classification system was not developed to address legally rel- evant questions such as proximate cause in civil cases, the best interests of children in custody disputes, or whether children require the protection of the Juvenile Court in child abuse cases. Although trauma assessment can be undertaken in any of the psycholegal contexts described above, if the forensic psychologist uses only the DSM classification system, impor- tant areas of legally relevant information related to the child’s response to traumatic events may be overlooked. Some chil- dren experience problems not detectable on standardized tests. Some have few symptoms; those who do not reach thresholds of clinical concern may yet be at risk for “sleeper” effects, experiencing significant problems later in the developmental sequence. The American Academy of Child and Adolescent Psychiatry (1998) noted that PTSD in children may be under- diagnosed, possibly because the diagnostic criteria are not developmentally sensitive or because available methods for assessment make it difficult to detect these effects. Phase-Related Trauma Symptomatology Forensic evaluators of trauma should recognize that the acute, chronic, and delayed-onset phases of the disorder may pro- duce different symptoms of different intensity or frequency in children at different developmental stages. Children in the acute phase may have nightmares, distressing dreams, hyper- vigilance, difficulty falling asleep, generalized anxiety, and an exaggerated startle response. A different symptom pattern among children whose PTSD had moved into a chronic form was noted by Famularo, Kinscherff, and Fenton (1990) for children suffering long-standing difficulties with detachment, restricted range of affect, sadness, dissociative episodes, es- trangement from others, and a future expectation that life will be difficult. Determinants of Traumatic Effects How a child reacts to a stressful event is a function of a com- plex biopsychosocial process, including, but not limited to, the level of stress; the nature of the traumatic event; the indi- vidual’s coping ability, predisposition for autonomic arousal, and personality; the constructive support available from care- takers following the trauma; and comorbid or premorbid de- velopmental/psychological conditions. The impact of any potentially traumatic experience depends not only on the characteristics of the event, but also on the child’s tempera- ment, neurodevelopmental reactivity, attachment status, and a variety of risk-protective factors (e.g., family functioning and emotional resources; Saywitz, Mannarino, Berliner, & Cohen, 2000). Briere (1997) summarized the determiners of posttraumatic responses. He includes such factors as the characteristics of the stress, variables specific to the victim, subjective response to the stress, and the response of others to the victim. These factors can account for significant vari- ability among children who experience what appears to be equivalent stresses. These findings underscore why it is es- sential for forensic evaluators to view each child’s situation as unique. The developmental vulnerability of the child may increase the significance of the response by caretakers or oth- ers toward that child, thus highlighting the need for a child forensic evaluation to carefully consider this factor. Understanding Trauma as Developmental Psychopathology It is essential that forensic evaluators of childhood trauma un- derstand developmental psychopathology. This provides an integrative framework for understanding the normal trajec- tory of changes in children in general, and how disruptions in childhood development can occur at later stages in the child’s life. Examined in this framework, the disruptive effects of traumatic experience can be understood to have consequences on the child’s future ability to process information, regulate affect, and adapt socially (Berliner, 1997). The potential for future developmental disruption to a child’s functioning is one distinguishing feature in assessing trauma in children as compared to adults. It is clear, however, that childhood trauma may have profound effects on all of adult functioning, to the extent that childhood trauma may be considered a mitigating factor in death penalty cases (Goldstein & Goldstein, in press). At times, a traumatic event can exacerbate a preexist- ing psychological condition, such as a child’s anxiety and loss following a conflictual divorce in his or her family. It is always important for the forensic evaluator to recog- nize that the presence of legitimate psychological symptoms Definitions of Trauma 213 does not necessarily mean that they represent legally relevant evidence of impairment. For example, and as described later, whether psychological impairments are proximately related to legally contested events is an essential consideration for psychological evaluation of damages in a personal injury civil litigation. Biological Reactions to Trauma Traumatic events can produce a complex interaction between behavioral and biological stress responses systems. DeBellis and Putnam (1994) noted that multiple, densely intercon- nected, neurobiological systems were likely to be impacted by acute and chronic stressors associated with the traumatic event. The dysregulation of stress response systems within the child may impact emerging neurodevelopment and thus be potentially more detrimental to a child than to an adult. These major systems can have significant implications for the strength of mood dysregulation, including anxiety and depression. Evaluation should include an assessment of be- havioral manifestations of motor restlessness due to hyper- aroused stress systems and /or learning and memory deficits that may be secondary to anxiety. In addition, DeBellis and Putnam suggest that it is important to note the biological role in understanding traumatic effects because of the potential use of pharmacological treatments for specific target symp- toms. Such treatment may represent an important element that determines the prognosis for the child’s recove
