반응성 애착장애 (영어: RAD, Reactive Attachment Disorder)는 아이들이 앓을 수 있는 심각하고 상대적으로 흔하지 않은 애착장애 중 하나로 의료 문헌에서 언급되고 있다.[1][2] 반응성 애착장애는 사회적인 문맥에 대해서 눈에 띄게 뒤틀려 있고 적당한 발달 과정을 거치지 못하는 것으로 특징지어진다. 반응성 애착장애의 양상은 대부분의 사회적 상호작용을 발달과정상 적절한 방법으로 수행하지 못하는 모습, 혹은 '무차별적인 사회성'으로 부를 수 있을 - 보통 사람들이면 친근하게 다가가지 못할 사람들에게까지 극도의 친근함을 보이는 모습으로 보여질 수 있다. (전자를 '억제형' 유형으로, 후자를 '탈억제형' 유형으로 부른다.) 이 용어는 세계 건강 기구가 출간한 질병 및 관련 건강 문제의 국제 통계 분류 (ICD-10) 과 [3] DSM-IV-TR, 즉 미국 정신의학 협회정신질환 진단 및 통계 편람의 4판의 개정판 (DSM).[4] ICD-10에서는 억제형의 유형을 RAD라고 부르고 탈억제형의 유형을 "무절제형 애착 장애" 즉 DAD(영어: disinhibited attachment disorder)라고 부르지만, DSM에서는 두 가지 유형을 모두 RAD라고 부른다. 언급의 편리함을 위해, 이 문서에서는 두 가지 형태 모두를 반응성 애착장애라고 부르도록 한다.

반응성 애착장애는 초기 아동기에 1차적 양육자와 정상적인 애착 관계를 형성하지 못하는 데서 발생한다. 그 원인으로는 초기 아동기의 과중한 무시, 학대, 생후 6개월부터 만 3세까지의 양육자와의 돌연적인 이별, 양육자의 잦은 교체, 혹은 아동의 상호작용을 위한 노력에 대한 양육자의 무시 등등을 들 수 있다. 하지만 그러한 경우가 모두 반응성 애착장애로 연결되는 것은 아니다. 심지어는 그러한 경험을 한 대다수가 반응성 애착장애로 연결되는 것마저 아니다[5] 본 장애는 전반적 발달 장애 혹은 발달 지연과도 다르며, 지적장애를 동시에 앓는 경우와도 다르다. 앞에서 예거한 모든 장애가 애착행동에 영향을 미칠 수 있다. 반응성 애착장애를 진단하기 위한 기준은 불안형 혹은 와해형 애착 등, 애착 형태에 대한 범주화 혹은 평가에 쓰이는 기준과는 매우 다르다.

반응성 애착장애를 가진 아동은 이후의 삶의 단계에서 대인관계적 혹은 품행적인 어려움을 초래할 수 있는, internal working models의 광범위한 불안을 보일 것으로 추측된다. 장기적 영향을 밝혀내기 위한 연구가 몇 차례 있었는데, 만 5세가 넘은 아동에게서 이 장애가 어떻게 발현되는지에 대해서는 명확히 밝혀진 바가 없다.[6][7] 다만, 1990년대 초반 냉전 종결 시기에 동유럽의 많은 고아원들이 개방되었을 때, 아주 많은 것을 빼앗긴 환경에서 자란 영유아들을 연구할 기회가 주어진 바 있다. 그러한 연구를 통해 애착장애의 유행과 원인, 하부 기전, 그리고 평가에 대한 이해의 폭이 넓어졌고, 1990년대 후반에는 애착장애의 치료/예방 혹은 더 나은 평가 방법을 개발하는 데까지 성과가 미쳤다. 해당 분야의 주류 이론가들은 현행 진단 기준을 넘어 애착에 관련된 문제에 의해서 생기는 더 넓은 범위의 문제들을 다뤄야 한다고 제안했다.[8]

반응성 애착장애 및 기타 문제성 초기 애착 행동에 대해 주류적으로 시행되고 있는 치료 및 예방 프로그램은 애착 이론에 기초하여 양육자의 반응성과 세심함을 증가시키고, 그것이 불가능하다면 다른 양육자에게 아동을 양육시키는 것에 초점을 두고 있다.[9] 이러한 대부분의 전략은 현재 평가 과정에 있다. 주류적인 이론가들과 임상가들은 반응성 애착장애에 대한 공인받지 못한 혹은 (애착 치료로 알려져 있는) 대체의학 현장에서의 진단 혹은 치료에 대해서 신랄한 비판을 가하고 있다. 이른바 '애착 치료'는 주류 이론에서 어긋난 이론적 기반을 갖고 있는 채 ICD-10과 DSM-4-TR 혹은 애착 이론에 관련이 없는 진단 기준 혹은 증상 목록을 사용한다. 이른바 '애착 치료'에서는 다양한 방식의 '치료적 접근'을 시도하는데, 이들 중 일부는 신체적으로 강압적이며 현재의 주류 애착 이론에 정면으로 배치되는 것으로 여겨진다.[10]

징후 및 증상[편집]

반응성 애착장애가 의심되는 아동에게 그러한 의심을 맨 처음으로 제기할 수 있는 의료 전문가는 아마 소아청소년과 의사일 것이다. The initial presentation varies according to the child's developmental and chronological age, although it always involves a disturbance in social interaction. Infants up to about 18–24 months may present with non-organic failure to thrive and display abnormal responsiveness to stimuli. Laboratory investigations will be unremarkable barring possible findings consistent with malnutrition or dehydration, while serum growth hormone levels will be normal or elevated.[11]

The core feature is severely inappropriate social relating by affected children. This can manifest itself in two ways:

  1. Indiscriminate and excessive attempts to receive comfort and affection from any available adult, even relative strangers (older children and adolescents may also aim attempts at peers)
  2. Extreme reluctance to initiate or accept comfort and affection, even from familiar adults, especially when distressed[12]

While RAD is likely to occur in relation to neglectful and abusive treatment, automatic diagnoses on this basis alone cannot be made, as children can form stable attachments and social relationships despite marked abuse and neglect.[13]

진단 기준[편집]

아직까지는 모두에게 이의 없이 받아들여지는 반응성 애착장애의 진단 기준은 없다. 연구와 진단을 위해 다양한 종류의 수단이 사용되는 일이 많다. Recognized assessment methods of attachment styles, difficulties or disorders include the Strange Situation Procedure (devised by developmental psychologist Mary Ainsworth),[14][15][16] the separation and reunion procedure and the Preschool Assessment of Attachment,[17] the Observational Record of the Caregiving Environment,[18] the Attachment Q-sort[19] and a variety of narrative techniques using stem stories, puppets or pictures. For older children, actual interviews such as the Child Attachment Interview and the Autobiographical Emotional Events Dialogue can be used. Caregivers may also be assessed using procedures such as the Working Model of the Child Interview.[20]

More recent research also uses the Disturbances of Attachment Interview (DAI) developed by Smyke and Zeanah (1999).[21] The DAI is a semi-structured interview designed to be administered by clinicians to caregivers. It covers 12 items, namely "having a discriminated, preferred adult", "seeking comfort when distressed", "responding to comfort when offered", "social and emotional reciprocity", "emotional regulation", "checking back after venturing away from the care giver", "reticence with unfamiliar adults", "willingness to go off with relative strangers", "self-endangering behavior", "excessive clinging", "vigilance/hypercompliance" and "role reversal". This method is designed to pick up not only RAD but also the proposed new alternative categories of disorders of attachment.

원인[편집]

Although increasing numbers of childhood mental health problems are being attributed to genetic defects,[22] reactive attachment disorder is by definition based on a problematic history of care and social relationships. Abuse can occur alongside the required factors, but on its own does not explain attachment disorder.[23] It has been suggested that types of temperament, or constitutional response to the environment, may make some individuals susceptible to the stress of unpredictable or hostile relationships with caregivers in the early years.[24] In the absence of available and responsive caregivers it appears that some children are particularly vulnerable to developing attachment disorders.[25]

There is as yet no explanation for why similar abnormal parenting may produce the two distinct forms of the disorder, inhibited and disinhibited. The issue of temperament and its influence on the development of attachment disorders has yet to be resolved. RAD has never been reported in the absence of serious environmental adversity yet outcomes for children raised in the same environment vary widely.[26]

From a neurobiological perspective, during the early formation of the brain, first of the brain stem, followed by the diencephalon, limbic system, and cortex,[27] research indicates a caregiver’s negative behaviors and responses impact the brain development of an infant or young child.[28] In particular, attachment patterns that are established though interactions between the caregiver and the infant or young child’s developing limbic system, which is responsible for regulating physical needs such as hunger and thirst, experiencing and expressing emotion, and desire for social and emotional contact,[29] are considered determinants for the neural connections, or “mental template” that are established for social connections and relationships with others[27] and requires significant stimuli during the first several months and years of life.[29]

The stimulation of two major neural networks in particular are identified as important in attachment. One is sensory perception, which is associated with caregiver interactions, such as the sight of a face, voice, touch, and scent. The other are neural networks associated with “pleasure,” which are activated when an infant or young child’s needs are being met, through relief of distress, attention, and play. These two connections, when they occur frequently and simultaneously, create an association of pleasure with human interaction and over time strengthen the connection between these neural pathways. In environments where children suffer from abuse or neglect, these neural connections remain underdeveloped and/or create or maintain aberrant neural pathways,[29] which can result in symptoms and behaviors under the DSM-IV-TR criteria of RAD.[30] Furthermore, research indicates that theses attachment patterns are most deeply imprinted on the brain during specific times of life, or “sensitive periods,” generally before three years of age.[27]

In discussing the neurobiological basis for attachment and trauma symptoms in a seven-year twin study, it has been suggested that the roots of various forms of psychopathology, including RAD, Borderline Personality Disorder (BPD), and post-traumatic stress disorder (PTSD), can be found in disturbances in affect regulation. The subsequent development of higher-order self-regulation is jeopardized and the formation of internal models is affected. Consequently the "templates" in the mind that drive organized behavior in relationships may be impacted. The potential for “re-regulation” (modulation of emotional responses to within the normal range) in the presence of “corrective” experiences (normative caregiving) seems possible.[31]

진단[편집]

반응성 애착장애는 DSM에서 가장 연구가 덜 되어 있고 가장 이해의 정도가 낮은 장애 중 하나이다. 반응성 애착장애에 대해서 체계적인 역학 조사는 거의 이뤄지지 않았으며, 아직까지는 이 장애의 형성 과정에 대해서 저명하게 인정받는 학설이 없고 정확하게 진단하는 것도 어려워 보인다.[12] There is a lack of clarity about the presentation of attachment disorders over the age of five years and difficulty in distinguishing between aspects of attachment disorders, disorganized attachment or the consequences of maltreatment.[7]

미국 소아청소년 정신의학회 (영어: American Academy of Child and Adolescent Psychiatry, AACAP)에 따르면, 반응성 애착장애의 징후를 보이는 아이들은 개개인에게 맞춘 정신의학적 평가와 치료 프로그램이 필요하다고 한다. 반응성 애착장애의 징후와 증상은 다른 정신의학적 장애에서도 발견될 수 있고 AACAP에서는 아동 개개인에게 맞춘 평가 없이 이러한 꼬리표나 진단을 내리면 안 된다고 조언한다.[32] Their practice parameter states that the assessment of reactive attachment disorder requires evidence directly obtained from serial observations of the child interacting with his or her primary caregivers and history (as available) of the child’s patterns of attachment behavior with these caregivers. It also requires observations of the child’s behavior with unfamiliar adults and a comprehensive history of the child’s early caregiving environment including, for example, pediatricians, teachers, or caseworkers.[6] In the US, initial evaluations may be conducted by psychologists, psychiatrists, specialist Licensed Clinical Social Workers or psychiatric nurses.[33]

영국에서는, 영국 입양자 및 양부모 협회 (영어: British Association for Adoption and Fostering, BAAF) 에서는 오직 정신의학자만이 애착장애를 진단해야 하며 그러한 어떤 평가도 아동의 개인적인 역사 혹은 가족력에 대한 종합적인 평가를 반드시 포함해야 한다고 주장한다. [34]

AACAP Practice Parameter (2005) 에 따르면, 더 성장한 아동이나 성인에게 애착장애를 진단할 수 있는지에 대한 문제는 아직 풀리지 않았다. 반응성 애착장애를 진단할 때 평가하는 애착 행동은 발달 과정에 따라 눈에 띄게 변화하며 더 성장한 아동에게서 그 진단 기준이 말하는 애착 행동과 유사한 행동이 무엇인지를 정의하는 것은 어렵다. 중기 아동기 혹은 초기 청소년기의 애착 행동을 평가하기 위한 공인된 척도는 아직까지 전혀 만들어진 바가 없다.[6] 학령기의 아동에 대해서 반응성 애착장애의 유병 여부를 평가하는 것은 전혀 불가능할 지도 모른다. 학령기부터는 아동은 각기 자신만의 발달 과정을 밟기 때문에 초기 아동기의 애착 경험은 학령기 아동의 정서나 행동을 결정하는 수많은 요인 중 하나에 불과하게 되기 때문이다.[35]

준거[편집]

ICD-10 describes reactive attachment disorder of childhood, known as RAD, and disinhibited attachment disorder, less well known as DAD. DSM-IV-TR also describes reactive attachment disorder of infancy or early childhood divided into two subtypes, inhibited type and disinhibited type, both known as RAD. The two classifications are similar, and both include:

  • markedly disturbed and developmentally inappropriate social relatedness in most contexts (e.g., the child is avoidant or unresponsive to care when offered by caregivers or is indiscriminately affectionate with strangers);[36]
  • the disturbance is not accounted for solely by developmental delay and does not meet the criteria for pervasive developmental disorder;
  • onset before five years of age (there is no age specified before five years of age at which RAD cannot be diagnosed);[36]
  • a history of significant neglect;
  • an implicit lack of identifiable, preferred attachment figure.

ICD-10 states in relation to the inhibited form only that the syndrome probably occurs as a direct result of severe parental neglect, abuse, or serious mishandling. DSM states in relation to both forms there must be a history of "pathogenic care" defined as persistent disregard of the child's basic emotional or physical needs or repeated changes in primary caregiver that prevents the formation of a discriminatory or selective attachment that is presumed to account for the disorder. For this reason, part of the diagnosis is the child's history of care rather than observation of symptoms.

In DSM-IV-TR the inhibited form is described as: Persistent failure to initiate or respond in a developmentally appropriate fashion to most social interactions, as manifest by excessively inhibited, hypervigilant, or highly ambivalent and contradictory responses (e.g. the child may respond to caregivers with a mixture of approach, avoidance, and resistance to comforting, or may exhibit "frozen watchfulness", hypervigilance while keeping an impassive and still demeanour).[4] Such infants do not seek and accept comfort at times of threat, alarm or distress, thus failing to maintain "proximity", an essential element of attachment behavior. The disinhibited form shows: Diffuse attachments as manifest by indiscriminate sociability with marked inability to exhibit appropriate selective attachments (e.g., excessive familiarity with relative strangers or lack of selectivity in choice of attachment figures).[4] There is therefore a lack of "specificity" of attachment figure, the second basic element of attachment behavior.

The ICD-10 descriptions are comparable save that ICD-10 includes in its description several elements not included in DSM-IV-TR as follows:

  • abuse, (psychological or physical), in addition to neglect;
  • associated emotional disturbance;
  • poor social interaction with peers, aggression towards self and others, misery, and growth failure in some cases, (inhibited form only);
  • evidence of capacity for social reciprocity and responsiveness as shown by elements of normal social relatedness in interactions with appropriately responsive, non-deviant adults, (disinhibited form only).

The first of these is somewhat controversial, being a commission rather than omission and because abuse of itself does not lead to attachment disorder.

The inhibited form has a greater tendency to ameliorate with an appropriate caregiver, while the disinhibited form is more enduring.[37] ICD-10 states the disinhibited form "tends to persist despite marked changes in environmental circumstances". Disinhibited and inhibited are not opposites in terms of attachment disorder and can coexist in the same child.[38] The question of whether there are in fact two subtypes has been raised. The World Health Organization acknowledges that there is uncertainty regarding the diagnostic criteria and the appropriate subdivision.[3] One reviewer has commented on the difficulty of clarifying the core characteristics of and differences between atypical attachment styles and various ways of categorizing more severe disorders of attachment.[39]

As of 2010, the American Psychiatric Association has proposed to redefine RAD into two distinct disorders in the DSM-V.[40] Corresponding with the inhibited type, one disorder will be reclassified as Reactive Attachment Disorder of Infancy and Early Childhood. [36]

In regards to pathogenic care, or the type of care in which these behaviors are present, a new criterion for Disinhibited Social Engagement Disorder now includes chronically harsh punishment or other types of severely inept caregiving. Relating to pathogenic care for both proposed disorders, a new criterion is rearing in atypical environments such as institutions with high child/caregiver ratios that cut down on opportunities to form attachments with a caregiver.[40]

감별 진단[편집]

반응성 애착장애의 진단이 복잡하다는 것은 감별 진단에 있어 특히 전문성이 있는 훈련받은 정신건강 전문가의 신중한 진단적 평가가 필수적이라는 것을 의미한다.[41][42][43] 품행장애, 반항성 장애, 불안장애, 외상 후 스트레스 장애, 사회 공포증 등 몇 가지 다른 질환들은 반응성 애착장애와 많은 증상을 공유하며 반응성 애착장애와 같이 유병되는 경우 혹은 상호 오진되어 과잉진단 혹은 과소진단을 이끌어내는 경우가 흔하다. 반응성 애착장애는 자폐 범주성 장애, 전반적 발달 장애, 아동기 조현병 혹은 몇몇 유전성 질환 등 뇌신경학적 장애와 상호 오진될 수도 있다. 이 장애를 앓는 유아와 장기 손상을 앓는 아동을 구분하는 방법은, 신체에 대한 병원 치료 이후로 아동의 상태가 급속도로 호전되는지 여부로 구분할 수 있다.[11] 자폐성 장애를 앓고 있는 아동은 몸집과 몸무게가 정상 수준이며 지적장애의 양상을 보이는 경우가 흔하다.[11][41][42][43]

대체 (代替) 진단[편집]

In the absence of a standardized diagnosis system, many popular, informal classification systems or checklists, outside the DSM and ICD, were created out of clinical and parental experience within the field known as attachment therapy. These lists are unvalidated and critics state they are inaccurate, too broadly defined or applied by unqualified persons. Many are found on the websites of attachment therapists. Common elements of these lists such as lying, lack of remorse or conscience and cruelty do not form part of the diagnostic criteria under either DSM-IV-TR or ICD-10.[44] Many children are being diagnosed with RAD because of behavioral problems that are outside the criteria.[41] There is an emphasis within attachment therapy on aggressive behavior as a symptom of what they describe as attachment disorder whereas mainstream theorists view these behaviors as comorbid, externalizing behaviors requiring appropriate assessment and treatment rather than attachment disorders. However, knowledge of attachment relationships can contribute to the etiology, maintenance and treatment of externalizing disorders.[45]

The Randolph Attachment Disorder Questionnaire or RADQ is one of the better known of these checklists and is used by attachment therapists and others.[46] The checklist includes 93 discrete behaviours, many of which either overlap with other disorders, like conduct disorder and oppositional defiant disorder, or are not related to attachment difficulties. Critics assert that it is unvalidated[47] and lacks specificity.[48]

치료[편집]

Assessing the child's safety is an essential first step that determines whether future intervention can take place in the family unit or whether the child should be removed to a safe situation. Interventions may include psychosocial support services for the family unit (including financial or domestic aid, housing and social work support), psychotherapeutic interventions (including treating parents for mental illness, family therapy, individual therapy), education (including training in basic parenting skills and child development), and monitoring of the child's safety within the family environment[11]

In 2005 the American Academy of Child and Adolescent Psychiatry laid down guidelines (devised by N.W. Boris and C.H. Zeanah) based on its published parameters for the diagnosis and treatment of RAD.[6] Recommendations in the guidelines include the following:

  1. "The most important intervention for young children diagnosed with reactive attachment disorder and who lack an attachment to a discriminated caregiver is for the clinician to advocate for providing the child with an emotionally available attachment figure."
  2. "Although the diagnosis of reactive attachment disorder is based on symptoms displayed by the child, assessing the caregiver's attitudes toward and perceptions about the child is important for treatment selection."
  3. "Children with reactive attachment disorder are presumed to have grossly disturbed internal models for relating to others. After ensuring that the child is in a safe and stable placement, effective attachment treatment must focus on creating positive interactions with caregivers."
  4. "Children who meet criteria for reactive attachment disorder and who display aggressive and oppositional behavior require adjunctive (additional) treatments."

Mainstream prevention programs and treatment approaches for attachment difficulties or disorders for infants and younger children are based on attachment theory and concentrate on increasing the responsiveness and sensitivity of the caregiver, or if that is not possible, placing the child with a different caregiver.[6][49][50] These approaches are mostly in the process of being evaluated. The programs invariably include a detailed assessment of the attachment status or caregiving responses of the adult caregiver as attachment is a two-way process involving attachment behavior and caregiver response. Some of these treatment or prevention programs are specifically aimed at foster carers rather than parents, as the attachment behaviors of infants or children with attachment difficulties often do not elicit appropriate caregiver responses.[51] Approaches include "Watch, wait and wonder",[52] manipulation of sensitive responsiveness,[53][54] modified "Interaction Guidance",[55] "Clinician-Assisted Videofeedback Exposure Sessions (CAVES)",[56] "Dyadic Developmental Psychotherapy" [57],[58],[59], "Preschool Parent Psychotherapy",[60] "Circle of Security",[61][62] "Attachment and Biobehavioral Catch-up" (ABC),[63] the New Orleans Intervention,[64][65][66] and parent–child psychotherapy.[67] Other treatment methods include Developmental, Individual-difference, and Relationship-based therapy (DIR, also referred to as Floor Time) by Stanley Greenspan, although DIR is primarily directed to treatment of pervasive developmental disorders.[68]

The relevance of these approaches to intervention with fostered and adopted children with RAD or older children with significant histories of maltreatment is unclear.[69]

대체의학에서의 치료[편집]

Outside the mainstream programs is a form of treatment generally known as attachment therapy, a subset of techniques (and accompanying diagnosis) for supposed attachment disorders including RAD. In general, these therapies are aimed at adopted or fostered children with a view to creating attachment in these children to their new caregivers. The theoretical base is broadly a combination of regression and catharsis, accompanied by parenting methods which emphasize obedience and parental control.[70] There is considerable criticism of this form of treatment and diagnosis as it is largely unvalidated and has developed outside the scientific mainstream.[71] There is little or no evidence base and techniques vary from non-coercive therapeutic work to more extreme forms of physical, confrontational and coercive techniques, of which the best known are holding therapy, rebirthing, rage-reduction and the Evergreen model. These forms of the therapy may well involve physical restraint, the deliberate provocation of rage and anger in the child by physical and verbal means including deep tissue massage, aversive tickling, enforced eye contact and verbal confrontation, and being pushed to revisit earlier trauma.[72][73] Critics maintain that these therapies are not within the attachment paradigm, are potentially abusive,[74] and are antithetical to attachment theory.[10] The APSAC Taskforce Report of 2006 notes that many of these therapies concentrate on changing the child rather than the caregiver.[75] Children may be described as "RADs", "Radkids" or "Radishes" and dire predictions may be made as to their supposedly violent futures if they are not treated with attachment therapy.[70] The Mayo Clinic, a well known U.S. non-profit medical practice and medical research group, cautions against consulting with mental health providers who promote these types of methods and offer evidence to support their techniques; to date, this evidence base is not published within reputable medical or mental health journals.[76]

Prognosis[편집]

The AACAP guidelines state that children with reactive attachment disorder are presumed to have grossly disturbed internal models for relating to others.[6] However, the course of RAD is not well studied and there have been few efforts to examine symptom patterns over time. The few existing longitudinal studies (dealing with developmental change with age over a period of time) involve only children from poorly run Eastern European institutions.[6]

Findings from the studies of children from Eastern European orphanages indicate that persistence of the inhibited pattern of RAD is rare in children adopted out of institutions into normative care-giving environments. However, there is a close association between duration of deprivation and severity of attachment disorder behaviors.[77] The quality of attachments that these children form with subsequent care-givers may be compromised, but they probably no longer meet criteria for inhibited RAD.[78] The same group of studies suggests that a minority of adopted, institutionalized children exhibit persistent indiscriminate sociability even after more normative caregiving environments are provided.[31] Indiscriminate sociability may persist for years, even among children who subsequently exhibit preferred attachment to their new caregivers. Some exhibit hyperactivity and attention problems as well as difficulties in peer relationships.[79] In the only longitudinal study that has followed children with indiscriminate behavior into adolescence, these children were significantly more likely to exhibit poor peer relationships.[80]

Studies of children who were reared in institutions have suggested that they are inattentive and overactive, no matter what quality of care they received. In one investigation, some institution-reared boys were reported to be inattentive, overactive, and markedly unselective in their social relationships, while girls, foster-reared children, and some institution-reared children were not. It is not yet clear whether these behaviors should be considered as part of disordered attachment.[81]

There is one case study on maltreated twins published in 1999 with a follow-up in 2006. This study assessed the twins between the ages of 19 and 36 months, during which time they suffered multiple moves and placements.[82] The paper explores the similarities, differences and comorbidity of RAD, disorganized attachment and post traumatic stress disorder. The girl showed signs of the inhibited form of RAD while the boy showed signs of the indiscriminate form. It was noted that the diagnosis of RAD ameliorated with better care but symptoms of post traumatic stress disorder and signs of disorganized attachment came and went as the infants progressed through multiple placement changes. At age three, some lasting relationship disturbance was evident.

In the follow-up case study when the twins were aged three and eight years, the lack of longitudinal research on maltreated as opposed to institutionalized children was again highlighted. The girl's symptoms of disorganized attachment had developed into controlling behaviors—a well-documented outcome. The boy still exhibited self-endangering behaviors, not within RAD criteria but possibly within "secure base distortion", (where the child has a preferred familiar caregiver, but the relationship is such that the child cannot use the adult for safety while gradually exploring the environment). At age eight the children were assessed with a variety of measures including those designed to access representational systems, or the child's "internal working models". The twins' symptoms were indicative of different trajectories. The girl showed externalizing symptoms (particularly deceit), contradictory reports of current functioning, chaotic personal narratives, struggles with friendships, and emotional disengagement with her caregiver, resulting in a clinical picture described as "quite concerning". The boy still evidenced self-endangering behaviors as well as avoidance in relationships and emotional expression, separation anxiety and impulsivity and attention difficulties. It was apparent that life stressors had impacted each child differently. The narrative measures used were considered helpful in tracking how early attachment disruption is associated with later expectations about relationships.[31]

One paper using questionnaires found that children aged three to six, diagnosed with RAD, scored lower on empathy but higher on self-monitoring (regulating your behavior to "look good"). These differences were especially pronounced based on ratings by parents, and suggested that children with RAD may systematically report their personality traits in overly positive ways. Their scores also indicated considerably more behavioral problems than scores of the control children.[83]

Epidemiology[편집]

Epidemiological data are limited, but reactive attachment disorder appears to be very uncommon.[1] The prevalence of RAD is unclear but it is probably quite rare, other than in populations of children being reared in the most extreme, deprived settings such as some orphanages.[25] There is little systematically gathered epidemiologic information on RAD.[41] A cohort study of 211 Copenhagen children to the age of 18 months found a prevalence of 0.9%.[84]

Attachment disorders tend to occur in a definable set of contexts such as within some types of institutions, in the presence of repeated changes of primary caregiver or of extremely neglectful identifiable primary caregivers who show persistent disregard for the child's basic attachment needs, but not all children raised in these conditions develop an attachment disorder.[85] Studies undertaken on children from Eastern European orphanages from the mid-1990s showed significantly higher levels of both forms of RAD and of insecure patterns of attachment in the institutionalized children, regardless of how long they had been there.[86][87][88] It would appear that children in institutions like these are unable to form selective attachments to their caregivers. The difference between the institutionalized children and the control group had lessened in the follow-up study three years later, although the institutionalized children continued to show significantly higher levels of indiscriminate friendliness.[86][89] However, even among children raised in the most deprived institutional conditions the majority did not show symptoms of this disorder.[77]

A 2002 study of children in residential nurseries in Bucharest, in which the DAI was used, challenged the current DSM and ICD conceptualizations of disordered attachment and showed that inhibited and disinhibited disorders could coexist in the same child.[87]

There are two studies on the incidence of RAD relating to high risk and maltreated children in the U.S. Both used ICD, DSM and the DAI. The first, in 2004, reported that children from the maltreatment sample were significantly more likely to meet criteria for one or more attachment disorders than children from the other groups, however this was mainly the proposed new classification of disrupted attachment disorder rather than the DSM or ICD classified RAD or DAD.[90] The second study, also in 2004, attempted to ascertain the prevalence of RAD and whether it could be reliably identified in maltreated rather than neglected toddlers. Of the 94 maltreated toddlers in foster care, 35% were identified as having ICD RAD and 22% as having ICD DAD, and 38% fulfilled the DSM criteria for RAD.[38] This study found that RAD could be reliably identified and also that the inhibited and disinhibited forms were not independent. However, there are some methodological concerns with this study. A number of the children identified as fulfilling the criteria for RAD did in fact have a preferred attachment figure.[91]

It has been suggested by some within the field of attachment therapy that RAD may be quite prevalent because severe child maltreatment, which is known to increase risk for RAD, is prevalent and because children who are severely abused may exhibit behaviors similar to RAD behaviors.[43] The APSAC Taskforce consider this inference to be flawed and questionable.[43] Severely abused children may exhibit similar behaviors to RAD behaviors but there are several far more common and demonstrably treatable diagnoses which may better account for these difficulties.[92] Further, many children experience severe maltreatment and do not develop clinical disorders.[92] Resilience is a common and normal human characteristic.[93] RAD does not underlie all or even most of the behavioral and emotional problems seen in foster children, adoptive children, or children who are maltreated and rates of child abuse and/or neglect or problem behaviors are not a benchmark for estimates of RAD.[43]

There are few data on comorbid conditions, but there are some conditions that arise in the same circumstances in which RAD arises, such as institutionalization or maltreatment. These are principally developmental delays and language disorders associated with neglect.[6] Conduct disorders, oppositional defiant disorder, anxiety disorders, post-traumatic stress disorder and social phobia share many symptoms and are often comorbid with or confused with RAD.[43][82] Attachment disorder behaviors amongst institutionalized children are correlated with attentional and conduct problems and cognitive levels but nonetheless appear to index a distinct set of symptoms and behaviors.[77]

Reactive attachment disorder first made its appearance in standard nosologies of psychological disorders in DSM-III, 1980, following an accumulation of evidence on institutionalized children. The criteria included a requirement of onset before the age of 8 months and was equated with failure to thrive. Both these features were dropped in DSM-III-R, 1987. Instead, onset was changed to being within the first 5 years of life and the disorder itself was divided into two subcategories, inhibited and disinhibited. These changes resulted from further research on maltreated and institutionalized children and remain in the current version, DSM-IV, 1994, and its 2000 text revision, DSM-IV-TR, as well as in ICD-10, 1992. Both nosologies focus on young children who are not merely at increased risk for subsequent disorders but are already exhibiting clinical disturbance.[94]

The broad theoretical framework for current versions of RAD is attachment theory, based on work conducted from the 1940s to the 1980s by John Bowlby, Mary Ainsworth and René Spitz. Attachment theory is a framework that employs psychological, ethological and evolutionary concepts to explain social behaviors typical of young children. Attachment theory focuses on the tendency of infants or children to seek proximity to a particular attachment figure (familiar caregiver), in situations of alarm or distress, behavior which appears to have survival value.[95] This is known as a discriminatory or selective attachment. Subsequently, the child begins to use the caregiver as a base of security from which to explore the environment, returning periodically to the familiar person. Attachment is not the same as love and/or affection although they are often associated. Attachment and attachment behaviors tend to develop between the ages of six months and three years. Infants become attached to adults who are sensitive and responsive in social interactions with the infant, and who remain as consistent caregivers for some time.[96] Caregiver responses lead to the development of patterns of attachment, that in turn lead to internal working models which will guide the individual's feelings, thoughts, and expectations in later relationships.[97][98] For a diagnosis of reactive attachment disorder, the child's history and atypical social behavior must suggest the absence of formation of a discriminatory or selective attachment.

The pathological absence of a discriminatory or selective attachment needs to be differentiated from the existence of attachments with either typical or somewhat atypical behavior patterns, known as styles or patterns. There are four attachment styles ascertained and used within developmental attachment research. These are known as secure, anxious-ambivalent, anxious-avoidant, (all organized)[14] and disorganized.[15][16] The latter three are characterised as insecure. These are assessed using the Strange Situation Procedure, designed to assess the quality of attachments rather than whether an attachment exists at all.[6]

A securely attached toddler will explore freely while the caregiver is present, engage with strangers, be visibly upset when the caregiver departs, and happy to see the caregiver return. The anxious-ambivalent toddler is anxious of exploration, extremely distressed when the caregiver departs but ambivalent when the caregiver returns. The anxious-avoidant toddler will not explore much, avoid or ignore the parent—showing little emotion when the parent departs or returns—and treat strangers much the same as caregivers with little emotional range shown. The disorganized/disoriented toddler shows a lack of a coherent style or pattern for coping. Evidence suggests this occurs when the caregiving figure is also an object of fear, thus putting the child in an irresolvable situation regarding approach and avoidance. On reunion with the caregiver, these children can look dazed or frightened, freezing in place, backing toward the caregiver or approaching with head sharply averted, or showing other behaviors implying fear of the person who is being sought. It is thought to represent a breakdown of an inchoate attachment strategy and it appears to affect the capacity to regulate emotions.[99]

Although there are a wide range of attachment difficulties within the styles which may result in emotional disturbance and increase the risk of later psychopathologies, particularly the disorganized style, none of the styles constitute a disorder in themselves and none equate to criteria for RAD as such.[100] A disorder in the clinical sense is a condition requiring treatment, as opposed to risk factors for subsequent disorders.[6] Reactive attachment disorder denotes a lack of typical attachment behaviors rather than an attachment style, however problematic that style may be, in that there is an unusual lack of discrimination between familiar and unfamiliar people in both forms of the disorder. Such discrimination does exist as a feature of the social behavior of children with atypical attachment styles. Both DSM-IV and ICD-10 depict the disorder in terms of socially aberrant behavior in general rather than focusing more specifically on attachment behaviors as such. DSM-IV emphasizes a failure to initiate or respond to social interactions across a range of relationships and ICD-10 similarly focuses on contradictory or ambivalent social responses that extend across social situations.[94] The relationship between patterns of attachment in the Strange Situation and RAD is not yet clear.[101]

There is a lack of consensus about the precise meaning of the term "attachment disorder".[102] The term is frequently used both as an alternative to reactive attachment disorder and in discussions about different proposed classifications for disorders of attachment beyond the limitations of the ICD and DSM classifications.[94] It is also used within the field of attachment therapy, as is the term reactive attachment disorder, to describe a range of problematic behaviors not within the ICD or DSM criteria or not related directly to attachment styles or difficulties at all.[103]

연구[편집]

Research from the late 1990s indicated there were disorders of attachment not captured by DSM or ICD and showed that RAD could be diagnosed reliably without evidence of pathogenic care, thus illustrating some of the conceptual difficulties with the rigid structure of the current definition of RAD.[104] Research published in 2004 showed that the disinhibited form can endure alongside structured attachment behavior (of any style) towards the child's permanent caregivers.[38]

Some authors have proposed a broader continuum of definitions of attachment disorders ranging from RAD through various attachment difficulties to the more problematic attachment styles. There is as yet no consensus, on this issue but a new set of practice parameters containing three categories of attachment disorder has been proposed by C.H. Zeanah and N. Boris. The first of these is disorder of attachment, in which a young child has no preferred adult caregiver. The proposed category of disordered attachment is parallel to RAD in its inhibited and disinhibited forms, as defined in DSM and ICD. The second category is secure base distortion, where the child has a preferred familiar caregiver, but the relationship is such that the child cannot use the adult for safety while gradually exploring the environment. Such children may endanger themselves, cling to the adult, be excessively compliant, or show role reversals in which they care for or punish the adult. The third type is disrupted attachment. Disrupted attachment is not covered under ICD-10 and DSM criteria, and results from an abrupt separation or loss of a familiar caregiver to whom attachment has developed.[105] This form of categorisation may demonstrate more clinical accuracy overall than the current DSM-IV-TR classification, but further research is required.[8][106] The practice parameters would also provide the framework for a diagnostic protocol. Most recently, Daniel Schechter and Erica Willheim have shown a relationship between some maternal violence-related posttraumatic stress disorder and secure base distortion (see above) which is characterized by child recklessness, separation anxiety, hypervigilance, and role-reversal.[107]

Some research indicates there may be a significant overlap between behaviors of the inhibited form of RAD or DAD and aspects of disorganized attachment where there is an identified attachment figure.[99]

An ongoing question is whether RAD should be thought of as a disorder of the child's personality or a distortion of the relationship between the child and a specific other person. It has been noted that as attachment disorders are by their very nature relational disorders, they do not fit comfortably into noslogies that characterize the disorder as centered on the person.[108] Work by C.H. Zeanah[38] indicates that atypical attachment-related behaviors may occur with one caregiver but not with another. This is similar to the situation reported for attachment styles, in which a particular parent's frightened expression has been considered as possibly responsible for disorganized/disoriented reunion behavior during the Strange Situation Procedure.[109]

The draft of the proposed DSM-V suggests dividing RAD into two disorders, Reactive Attachment Disorder for the current inhibited form of RAD, and Disinhibited Social Engagement Disorder for what is currently the disinhibited form of RAD, with some alterations in the proposed DSM definition.[110]
