'''Reactive attachment disorder''' ('''RAD''') is described in clinical literature as a severe [[attachment disorder|disorder]] that can affect children, although these issues do occasionally persist into adulthood.<ref name="DSM-IV-TR 2000 p. 129">DSM-IV-TR (2000) [[American Psychiatric Association]] p. 129.</ref><ref>{{cite journal | author = [[Daniel Schechter|Schechter]] DS, Willheim E | title = Disturbances of attachment and parental psychopathology in early childhood | journal = Child and Adolescent Psychiatric Clinics of North America | volume = 18 | issue = 3 | pages = 665–86 |date=July 2009 | pmid = 19486844 | doi = 10.1016/j.chc.2009.03.001 | pmc = 2690512}}</ref><ref>{{cite journal |author1=[[Marinus van IJzendoorn|Marinus]] van IJzendoorn MH |author2=Femmie Juffer | title = Behavior Problems and Mental Health Referrals of International Adoptees | journal = The Journal of the American Medical Association | volume = 293 | issue = 20 | pages = 2501–2515 |date= May 2005 | doi = 10.1001/jama.293.20.2501| pmid = 15914751 |s2cid=25576414 }}</ref> RAD is characterized by markedly disturbed and developmentally inappropriate ways of relating socially in most contexts.  It can take the form of a persistent failure to initiate or respond to most social interactions in a developmentally appropriate way—known as the "inhibited form". In the [[DSM-5]], the "disinhibited form" is considered a separate diagnosis named "[[disinhibited attachment disorder]]".

RAD arises from a failure to form normal attachments to primary caregivers in early childhood. Such a failure could result from severe early experiences of [[neglect]], [[abuse]], abrupt separation from caregivers between the ages of six months and three years, frequent changes of caregivers, or a lack of caregiver responsiveness to a child's communicative efforts. It is differentiated from [[pervasive developmental disorder]] or developmental delay and from possibly [[comorbidity|comorbid]] conditions such as [[intellectual disability]], all of which can affect attachment behavior. The criteria for a diagnosis of a reactive attachment ''disorder'' are very different from the criteria used in assessment or categorization of [[Attachment theory#Attachment patterns|attachment ''styles'']] such as insecure or disorganized attachment.

Children with RAD are presumed to have grossly disturbed internal working models of relationships that may lead to interpersonal and behavioral difficulties in later life. There are few studies of long-term effects, and there is a lack of clarity about the presentation of the disorder beyond the age of five years.<ref name=AACAP-2005/><ref name="prior228">Prior & Glaser (2006), p. 228.</ref> However, the opening of orphanages in Eastern Europe following the end of the [[Cold War]] in the early 1990s provided opportunities for research on infants and toddlers brought up in very deprived conditions. Such research broadened the understanding of the prevalence, causes, mechanism and assessment of disorders of attachment and led to efforts from the late 1990s onwards to develop treatment and prevention programs and better methods of assessment. Mainstream theorists in the field have proposed that a broader range of conditions arising from problems with attachment should be defined beyond current classifications.<ref name="oconzean2003">{{cite journal |vauthors=O'Connor TG, Zeanah CH |title=Attachment disorders: assessment strategies and treatment approaches |journal=Attach Hum Dev |volume=5 |issue=3 |pages=223–44 |year=2003 |pmid=12944216 |doi=10.1080/14616730310001593974 |s2cid=21547653 }}</ref>

Mainstream treatment and prevention programs that target RAD and other problematic early attachment behaviors 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.<ref>Prior & Glaser (2006), p. 231.</ref> Most such strategies are in the process of being evaluated. Mainstream practitioners and theorists have presented significant criticism of the diagnosis and treatment of alleged reactive attachment disorder or the theoretically baseless "attachment disorder" within the controversial form of psychotherapy commonly known as [[attachment therapy]]. Attachment therapy has a scientifically unsupported theoretical base and uses diagnostic criteria or symptom lists markedly different from criteria under ICD-10 or DSM-IV-TR, or to attachment behaviors. A range of treatment approaches are used in attachment ''therapy'', some of which are physically and psychologically coercive, and considered to be [[wikt: antithetical|antithetical]] to attachment ''theory''.<ref name="O'Connor & Nilsen">O'Connor TG, Nilsen WJ (2005).

==Signs and symptoms==
{{See also|Attachment theory| attachment disorder}}
[[Pediatricians]] are often the first health professionals to assess and raise suspicions of RAD in children with the disorder. The initial presentation varies according to the child's developmental and chronological age, although it always involves a disturbance in social interaction. [[Infant]]s up to about 18–24 months may present with [[Failure to thrive|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.<ref name=Sad04>{{cite book |title=Kaplan & Sadock's Concise Textbook of Clinical Psychiatry |last=Sadock |first=BJ |author2=Sadock VA |year=2004 |publisher=Lippincott Williams and Wilkins |location=Philadelphia |isbn=978-0-7817-5033-2 |pages=[https://archive.org/details/kaplansadockscon00sado/page/570 570–72] |url-access=registration |url=https://archive.org/details/kaplansadockscon00sado/page/570 }}</ref>

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

# 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). This may often appear as denial of comfort from anyone as well.
# Extreme reluctance to initiate or accept comfort and affection, even from familiar adults, especially when distressed.<ref name="Chaffin 2006, p. 80">Chaffin et al. (2006), p. 80. The APSAC Taskforce Report</ref>
#

While RAD occurs 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. However, the instances of that ability are rare.<ref name="Rutter 2002">{{cite journal |author=Rutter M |title=Nature, nurture, and development: from evangelism through science toward policy and practice |journal=Child Dev |volume=73 |issue=1 |pages=1–21 |year=2002 |pmid=14717240 |doi=10.1111/1467-8624.00388 }}</ref>

The name of the disorder emphasizes problems with attachment but the criteria include symptoms such as failure to thrive, a lack of developmentally appropriate social responsiveness, apathy, and onset before 8 months.<ref>{{Cite journal|last1=RICHTERS|first1=MARGOT MOSER|last2=VOLKMAR|first2=FRED R.|date=1 March 1994|title=Reactive Attachment Disorder of Infancy or Early Childhood|journal=Journal of the American Academy of Child & Adolescent Psychiatry|volume=33|issue=3|pages=328–332|doi=10.1097/00004583-199403000-00005|pmid=7513324|citeseerx=10.1.1.527.9988|s2cid=13058511 }}</ref>

There is as yet no universally accepted diagnostic protocol for reactive attachment disorder. Often a range of measures are used in research and diagnosis.

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.

==Causes==
Although increasing numbers of childhood mental health problems are being attributed to [[genetic defect]]s,<ref>Mercer (2006), pp. 104–05.</ref> 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.<ref>Prior &amp; Glaser (2006), p. 218.</ref> 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.<ref name="Marshall & Fox (2005)">{{cite journal |year=2005 |title=Relationship between behavioral reactivity at 4 months and attachment classification at 14 months in a selected sample |journal=Infant Behavior and Development |volume=28 |issue=4 |pages=492–502 |doi= 10.1016/j.infbeh.2005.06.002 |vauthors=Marshall PJ, Fox NA }}</ref> In the absence of available and responsive caregivers it appears that most children are particularly vulnerable to developing attachment disorders.<ref name="prior">Prior &amp; Glaser (2006), p. 219.</ref>

While similar abnormal parenting may produce the two distinct forms of the disorder, inhibited and disinhibited, studies show that abuse and neglect were far more prominent and severe in the cases of RAD, disinhibited type. 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 are the same.<ref name="Zeanah &amp; Fox (2004)">{{cite journal |vauthors=Zeanah CH, Fox NA |title=Temperament and attachment disorders |journal=J Clin Child Adolesc Psychol |volume=33 |issue=1 |pages=32–41 |year=2004 |pmid=15028539 |doi=10.1207/S15374424JCCP3301_4 |s2cid=9416146 }}</ref>

In discussing the [[Neurobiology|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 (psychology)|affect]] regulation. The subsequent development of higher-order [[Emotional dysregulation|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.<ref name="Heller et al. (2006)">{{cite journal |vauthors=Heller SS, Boris NW, Fuselier SH, Page T, Koren-Karie N, Miron D |title=Reactive attachment disorder in maltreated twins follow-up: from 18 months to 8 years |journal=Attach Hum Dev |volume=8 |issue=1 |pages=63–86 |year=2006 |pmid=16581624 |doi=10.1080/14616730600585177|s2cid=34947321 }}</ref>

==Diagnosis==
{{See also|Attachment measures}}
RAD is one of the least researched and most poorly understood disorders in the DSM. There is little systematic epidemiologic information on RAD, its course is not well established and it appears difficult to diagnose accurately.<ref name="Chaffin 2006, p. 80"/> 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.<ref name="prior228"/>

According to the [[American Academy of Child and Adolescent Psychiatry]] (AACAP), children who exhibit signs of reactive attachment disorder need a comprehensive psychiatric assessment and individualized treatment plan. The signs or symptoms of RAD may also be found in other psychiatric disorders and AACAP advises against giving a child this label or diagnosis without a comprehensive evaluation.<ref name="AACAP">[http://www.aacap.org/cs/root/facts_for_families/reactive_attachment_disorder Reactive Attachment Disorder.] {{webarchive|url=https://web.archive.org/web/20080203213050/http://www.aacap.org/cs/root/facts_for_families/reactive_attachment_disorder |date=3 February 2008 }} American Academy of Child & Adolescent Psychiatry, Facts for Families, No. 85; Updated December 2002.  Retrieved on 13 February 2008.</ref> Their practice parameter states that the assessment of reactive attachment disorder requires evidence directly obtained from serial observations of the child interacting with their 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.<ref name=AACAP-2005/> In the US, initial evaluations may be conducted by psychologists, psychiatrists, Licensed Marriage and Family Therapists, Licensed Professional Counselors, specialist Licensed Clinical Social Workers or psychiatric nurses.<ref>For examples see  [http://dcfswebresource.prairienet.org/resources/rad.php Reactive Attachment Disorder] {{webarchive|url=https://web.archive.org/web/20071228050441/http://dcfswebresource.prairienet.org/resources/rad.php |date=28 December 2007 }}, DCFS, State of Illinois and [http://www.azdhs.gov/bhs/guidance/attach.pdf DBHS Practice Protocol: Disturbances and Disorders of Attachment] (PDF), Arizona Department of Health Services, 2 October 2006. Retrieved on 23 February 2008.</ref>

In the UK, the [[British Association for Adoption and Fostering]] (BAAF) advise that only a psychiatrist can diagnose an attachment disorder and that any assessment must include a comprehensive evaluation of the child's individual and family history.<ref name="BAAF">[http://www.baaf.org.uk/about/believes/ps4.pdf Attachment Disorders, their Assessment and Intervention/Treatment] {{webarchive|url=https://web.archive.org/web/20081002051146/http://www.baaf.org.uk/about/believes/ps4.pdf |date=2 October 2008 }} (PDF). British Association for Adoption and Fostering, Position Statement 4, 2006. Retrieved on 23 February 2008</ref>

According to the AACAP Practice Parameter (2005) the question of whether attachment disorders can reliably be diagnosed in older children and adults has not been resolved. Attachment behaviors used for the diagnosis of RAD change markedly with development and defining analogous behaviors in older children is difficult. There are no substantially validated measures of attachment in middle childhood or early adolescence.<ref name=AACAP-2005/> Assessments of RAD past school age may not be possible at all as by this time children have developed along individual lines to such an extent that early attachment experiences are only one factor among many that determine emotion and behavior.<ref>Mercer (2006), p. 116.</ref>

===Criteria===
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);<ref name=DSMIV />
* the disturbance is not accounted for solely by [[Child development|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);<ref name=DSMIV>{{cite book|title=Diagnostic and Statistical Manual of Mental Disorders: Text Revision|url=https://archive.org/details/diagnosticstatis0ed4unse_y1p2|url-access=registration|year=2000|publisher=American Psychiatric Association|isbn=978-0-89042-025-6|pages=[https://archive.org/details/diagnosticstatis0ed4unse_y1p2/page/943 943]}}</ref>
* 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 [[medical diagnosis|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).<ref name= "DSM">{{cite book |title= Diagnostic and Statistical Manual of Mental Disorders |edition=4th ed., text revision ([[DSM-IV-TR]]) |author= American Psychiatric Association |year=2000 |isbn=978-0-89042-025-6 |chapter=Diagnostic criteria for 313.89 Reactive attachment disorder of infancy or early childhood  |publisher= AMERICAN PSYCHIATRIC PRESS INC (DC) |location= United States}}
</ref> Such infants do not seek or 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).<ref name ="DSM"/> 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:
* [[Child abuse|abuse]], ([[Psychological 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 in and 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.<ref>Prior &amp; Glaser (2006), pp. 220–21.</ref> 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.<ref name="Zeanah et al. (2004)"/> The question of whether there are two subtypes has been raised. The World Health Organization acknowledges that there is uncertainty regarding the diagnostic criteria and the appropriate subdivision.<ref name="WHO1992">World Health Organisation (1992) ''International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10)''. Geneva: World health Organization.</ref> One reviewer has commented on the difficulty of clarifying the core characteristics of and differences between atypical attachment styles and ways of categorizing more severe disorders of attachment.<ref>{{cite journal | author = Zilberstein K | year = 2006 | title = Clarifying core characteristics of attachment disorders | journal = [[American Journal of Orthopsychiatry]] | volume = 76 | issue = 1| pages = 55–64 | doi=10.1037/0002-9432.76.1.55| pmid = 16569127 | s2cid = 25416390 }}</ref>

{{as of|2010}}, the American Psychiatric Association has proposed to redefine RAD into two distinct disorders in the DSM-V.<ref name=DSM-V>Proposed Revision Reactive Attachment Disorder, ''American Psychiatric Association'' (2012). Retrieved from http://www.dsm5.org/ProposedRevisions/Pages/proposedrevision.aspx?rid=120</ref> Corresponding with the inhibited type, one disorder will be reclassified as ''Reactive Attachment Disorder of Infancy and Early Childhood''.<ref name=DSMIV />

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.<ref name=DSM-V />

===Differential diagnosis===
The diagnostic complexities of RAD mean that careful diagnostic evaluation by a trained [[mental health]] expert with particular expertise in [[differential diagnosis]] is considered essential.<ref name="Hanson&Spratt2000">{{cite journal |vauthors=Hanson RF, Spratt EG |title=Reactive Attachment Disorder: what we know about the disorder and implications for treatment |journal=Child Maltreat |volume=5 |issue=2 |pages=137–45 |year=2000 |pmid=11232086 |doi=10.1177/1077559500005002005 |s2cid=21497329 }}</ref><ref name="Wilson (2001)">{{cite journal |doi=10.1080/00223980109603678 |author=Wilson SL |title=Attachment disorders: review and current status |journal=J Psychol |volume=135 |issue=1 |pages=37–51 |year=2001 |pmid=11235838 |s2cid=7226465 }}</ref><ref name="taskforce"/> Several other disorders, such as [[conduct disorder]]s, [[oppositional defiant disorder]], [[anxiety disorder]]s, [[post traumatic stress disorder]] and [[social anxiety disorder|social phobia]] share many symptoms and are often comorbid with or confused with RAD, leading to over and under diagnosis. RAD can also be confused with neuropsychiatric disorders such as [[autism spectrum|autism]], [[pervasive developmental disorder]], [[pediatric schizophrenia|childhood schizophrenia]] and some genetic syndromes. Infants with this disorder can be distinguished from those with organic illness by their rapid physical improvement after hospitalization.<ref name=Sad04/> Autistic children are likely to be of normal size and weight and often exhibit a degree of intellectual disability. They are unlikely to improve upon being removed from the home.<ref name=Sad04/><ref name="Hanson&Spratt2000"/><ref name="Wilson (2001)"/><ref name="taskforce"/>

===Alternative diagnosis===
In the absence of a standardized diagnosis system, many popular, informal classification systems or checklists, outside the [[Diagnostic and Statistical Manual of Mental Disorders|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.<ref>Chaffin et al. (2006), pp. 82–83. The APSAC Taskforce Report</ref> Many children are being diagnosed with RAD because of behavioral problems that are outside the criteria.<ref name="Hanson&Spratt2000"/> 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, [[Externalization (psychology)|externalizing]] behaviors requiring appropriate assessment and treatment rather than attachment disorders. However, knowledge of attachment relationships can contribute to the cause, maintenance and treatment of externalizing disorders.<ref name="Gutman-Steinmetz &amp; Crowell (2006)">{{cite journal |vauthors=Guttmann-Steinmetz S, Crowell JA |title=Attachment and externalizing disorders: a developmental psychopathology perspective |journal=J Am Acad Child Adolesc Psychiatry |volume=45 |issue=4 |pages=440–51 |year=2006 |pmid=16601649 |doi=10.1097/01.chi.0000196422.42599.63 }}</ref>

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<ref name=Sad04/>

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.<ref name=AACAP-2005>{{cite journal |journal=Journal of the American Academy of Child and Adolescent Psychiatry |date=November 2005 |volume=44 |issue=11 |pages=1206–19 |title= Practice parameter for the assessment and treatment of children and adolescents with reactive attachment disorder of infancy and early childhood |last1=Boris |first1=Neil W. |last2=Zeanah |first2=Charles H. |author3=Work Group on Quality Issues |pmid=16239871 |url=http://www.jaacap.com/article/S0890-8567(09)62229-2/fulltext |doi=10.1097/01.chi.0000177056.41655.ce |doi-access=free }}</ref> Recommendations in the guidelines include the following:
# "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."
# "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."
# "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."
# "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.<ref name=AACAP-2005/><ref>Prior &amp; Glaser (2006), p. 231.</ref><ref name="BakermansKranenburg et al.

===Attachment therapy===
{{main|Attachment therapy}}

The terms [[attachment disorder]], attachment problems, and attachment therapy, although increasingly used, have no clear, specific, or consensus definitions. However, the terms and therapies often are applied to children who are maltreated, particularly those in the foster care, kinship care, or adoption systems, and related populations such as children adopted internationally from orphanages.<ref>{{Cite journal|last1=Chaffin|first1=Mark|last2=Hanson|first2=Rochelle|last3=Saunders|first3=Benjamin E.|last4=Nichols|first4=Todd|last5=Barnett|first5=Douglas|last6=Zeanah|first6=Charles|last7=Berliner|first7=Lucy|last8=Egeland|first8=Byron|last9=Newman|first9=Elana|date=1 February 2006|title=Report of the APSAC Task Force on Attachment Therapy, Reactive Attachment Disorder, and Attachment Problems|journal=Child Maltreatment|language=en|volume=11|issue=1|pages=76–89|doi=10.1177/1077559505283699|issn=1077-5595|pmid=16382093|s2cid=11443880}}</ref>

Outside the mainstream programs is a [[Attachment therapy#Treatment characteristics|form of treatment]] generally known as attachment therapy, a subset of techniques (and accompanying novel diagnosis) for supposed attachment disorders including RAD. These "attachment disorders" use diagnostic criteria or symptom lists different from criteria under ICD-10 or DSM-IV-TR, or to attachment behaviors. Those with "attachment disorder" are said to lack empathy and remorse.

Treatments of this pseudoscientific disorder are called "Attachment therapy". 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 [[Age regression in therapy|regression]] and [[catharsis]], accompanied by parenting methods which emphasize [[Obedience (human behavior)|obedience]] and parental control.<ref name="Chaffin 2006 pp. 79">Chaffin et al. (2006), pp. 79–80.

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.<ref>Chaffin et al.

==Prognosis==
The AACAP guidelines state that children with reactive attachment disorder are presumed to have grossly disturbed internal models for relating to others.<ref name=AACAP-2005/> 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 study|longitudinal studies]] (dealing with developmental change with age over a period of time) involve only children from poorly run Eastern European institutions.<ref name=AACAP-2005/>

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.<ref name="Connor &amp; Rutter (2000)">{{cite journal |vauthors=O'Connor TG, Rutter M |title=Attachment disorder behavior following early severe deprivation: extension and longitudinal follow-up.

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.<ref name="Roy et al.(2004)">{{cite journal |vauthors=Roy P, Rutter M, Pickles A |year=2004 |title=Institutional care: Associations between overactivity and lack of selectivity in social relationships|journal=Journal of Child Psychology and Psychiatry |volume=45 |issue=4 |pages=866–73  |doi=10.1111/j.1469-7610.2004.00278.x |pmid=15056316}}</ref>

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 had multiple moves and placements.<ref name="Hinshaw-Fusilier et al. (1999)">{{cite journal|last1=Hinshaw-Fuselier|first1=Sarah|last2=Boris|first2=Neil W.|last3=Zeanah|first3=Charles H.|title=Reactive attachment disorder in maltreated twins|journal=Infant Mental Health Journal|volume=20|issue=1| year=1999| pages=42–59|doi=10.1002/(SICI)1097-0355(199921)20:1<42::AID-IMHJ4>3.0.CO;2-B}}</ref> 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 [[Attachment measures#Other approaches|narrative measures]] used were considered helpful in tracking how early attachment disruption is associated with later expectations about relationships.<ref name="Heller et al. (2006)"/>

One paper using questionnaires found that children aged three to six, diagnosed with RAD, scored lower on empathy but higher on [[Self monitoring|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.<ref name="Hall &amp; Geher (2003)">{{cite journal |doi=10.1080/00223980309600605 |vauthors=Hall SE, Geher G |title=Behavioral and personality characteristics of children with reactive attachment disorder|journal=J Psychol |volume=137 |issue=2 |pages=145–62 |year=2003 |pmid=12735525|s2cid=32015193 }}</ref>

==Epidemiology==
Epidemiological data are limited, but reactive attachment disorder appears to be very uncommon.<ref name="DSM-IV-TR 2000 p. 129"/> 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.<ref name="prior" /> There is little systematically gathered [[epidemiology|epidemiologic]] information on RAD.<ref name="Hanson&Spratt2000"/> A cohort study of 211 Copenhagen children to the age of 18 months found a prevalence of 0.9%.<ref>{{cite journal  |vauthors=Skovgaard AM, Houmann T, Christiansen E, etal |year=2007 |title= The prevalence of mental health problems in children 1½ years of age&nbsp;– the Copenhagen Child Cohort 2000 |journal= J Child Psychol Psychiatry  |volume=48 |issue=1 |pages=62–70 |doi=10.1111/j.1469-7610.2006.01659.x |pmid= 17244271}}</ref>

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.<ref>Prior &amp; Glaser (2006), pp. 218–19.</ref> 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.<ref name="Chisholm et al.

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.<ref name="Smyke et al.(2002)">{{cite journal |vauthors=Smyke AT, Dumitrescu A, Zeanah CH |title=Attachment disturbances in young children.

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.<ref name="Boris et al.(2004)">{{cite journal |vauthors=Boris NW, Hinshaw-Fuselier SS, Smyke AT, Scheeringa MS, Heller SS, Zeanah CH |title=Comparing criteria for attachment disorders: establishing reliability and validity in high-risk samples |journal=J Am Acad Child Adolesc Psychiatry |volume=43 |issue=5 |pages=568–77 |year=2004 |pmid=15100563 |doi=10.1097/00004583-200405000-00010 }}</ref> 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.

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.<ref>Prior & Glaser (2006), p. 215.</ref>

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.<ref name="taskforce">Chaffin et al.

==History==
{{Main|Attachment theory|Attachment in children}}
Reactive attachment disorder first made its appearance in standard [[nosology|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.<ref name="Zean96">{{cite journal |author=Zeanah CH |title=Beyond insecurity: a reconceptualization of attachment disorders of infancy |journal=J Consult Clin Psychol |volume=64 |issue=1 |pages=42–52 |year=1996 |pmid=8907083 |doi=10.1037/0022-006X.64.1.42 }}</ref>

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 [[Psychology|psychological]], [[Ethology|ethological]] and [[Evolutionary psychology|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.<ref>Bowlby [1969] (1997 edition) pp. 224–27.</ref> 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 [[Human behavior|behaviors]] tend to develop between the ages of six months and three years. [[Attachment in children|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.<ref>Bowlby [1969] (1997 edition) pp. 313–17.</ref> 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.<ref name=" Bretherton &amp; Munholland 1999">Bretherton I, Munholland KA (1999). "Internal Working Models in Attachment Relationships: A Construct Revisited". In Cassidy J and Shaver PR (eds.) ''Handbook of Attachment: Theory, Research and Clinical Applications''. pp. 89–111. Guilford Press {{ISBN|1-57230-087-6}}.</ref><ref>Bowlby [1969] (1997 edition) p. 354.</ref> 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 [[Attachment in children#Attachment patterns|styles]] ascertained and used within developmental attachment research. These are known as ''secure'', ''anxious-ambivalent'', ''anxious-avoidant'', (all ''organized'')<ref name="Ainsworth et al. (1979)">Ainsworth MD, Blehar M, Waters E, Wall S (1979).

Chicago: University of Chicago Press. {{ISBN|0-226-30630-5}}.</ref> The latter three are characterised as ''insecure''. These are assessed using the [[Attachment measures#Measures of attachment in infants|Strange Situation Procedure]], designed to assess the quality of attachments rather than whether an attachment exists at all.<ref name=AACAP-2005/>

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.<ref name="Van Ijzendoorn &amp; Bakermans-Kranenburg (2003)"/>

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.<ref name="Thompson (2000)">{{cite journal |author=Thompson RA |title=The legacy of early attachments |journal=Child Dev |volume=71 |issue=1 |pages=145–52 |year=2000 |pmid=10836568 |doi=10.1111/1467-8624.00128 }}
</ref> A [[disease|disorder]] in the [[Clinical psychology|clinical]] sense is a condition requiring treatment, as opposed to risk factors for subsequent disorders.<ref name=AACAP-2005/> 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.<ref name="Zean96"/> The relationship between patterns of attachment in the Strange Situation and RAD is not yet clear.<ref name="O'Con '02">O'Connor TG (2002), "Attachment disorders in infancy and childhood". In Rutter M, Taylor E, (Eds.) ''Child and Adolescent Psychiatry: Modern Approaches'' (4th ed.) Blackwell Scientific publications. pp. 776–792. {{ISBN|0-632-01229-3}}</ref>

There is a lack of consensus about the precise meaning of the term "attachment disorder".<ref>Chaffin et al. (2006), p. 77. The APSAC Taskforce Report</ref> 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.<ref name="Zean96"/> 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.<ref>Chaffin et al. (2006), p. 82–83. The APSAC Taskforce Report</ref>

==Research==
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.<ref name="Boris et al. 1996">{{cite journal |vauthors=Boris NW, Zeanah CH, Larrieu JA, Scheeringa MS, Heller SS |title=Attachment disorders in infancy and early childhood: a preliminary investigation of diagnostic criteria|journal=Am J Psychiatry |volume=155 |issue=2 |pages=295–97 |date=1 February 1998|pmid=9464217|doi=10.1176/ajp.155.2.295|s2cid=23232613 |url=http://ajp.psychiatryonline.org/cgi/pmidlookup?view=long&pmid=9464217 |access-date=31 January 2008 |url-access=subscription }}</ref> Research published in 2004 showed that the disinhibited form can endure alongside structured attachment behavior (of any style) towards the child's permanent caregivers.<ref name="Zeanah et al. (2004)">{{cite journal |vauthors=Zeanah CH, Scheeringa M, Boris N, Heller S, Smyke A, Trapani J |date=August 2004 |title=Reactive Attachment Disorder in Maltreated Toddlers  |journal=Child Abuse & Neglect |volume=28 |issue=8 |doi=10.1016/j.chiabu.2004.01.010 |pages=877–88 |pmid=15350771 }}</ref>

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.<ref name="Boris &amp; Zeanah (1999)">{{cite journal |vauthors=Boris NW, Zeanah CH |year=1999 |title= Disturbance and disorders of attachment in infancy: An overview|journal=Infant Mental Health Journal |volume=20|pages=1–9 |doi= 10.1002/(SICI)1097-0355(199921)20:1<1::AID-IMHJ1>3.0.CO;2-V}}</ref> This form of categorisation may demonstrate more clinical accuracy overall than the current DSM-IV-TR classification, but further research is required.<ref name="oconzean2003" /><ref name="Zeanah 2000">Zeanah CH (2000). "Disturbances and disorders of attachment in early childhood". In Zeanah CH (Ed.) ''Handbook of infant mental health'' (2nd ed.) pp. 358–62. New York: Guilford Press. {{ISBN|1-59385-171-5}}</ref> 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.<ref>Schechter DS, Willheim E (2009).  Disturbances of attachment and parental psychopathology in early childhood.   Infant and Early Childhood Mental Health Issue.  Child and Adolescent Psychiatry Clinics of North America, 18(3), 665–687.</ref>

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.<ref name="Van Ijzendoorn &amp; Bakermans-Kranenburg (2003)">{{cite journal |vauthors=Van Ijzendoorn M, Bakermans-Kranenburg M |date=September 2003 |title=Attachment disorders and disorganized attachment: Similar and different |journal=Attachment & Human Development |volume=5 |issue=3 |pages=313–20(8) |doi= 10.1080/14616730310001593938 |pmid=12944229|s2cid=10644822 }}</ref>

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 nosologies that characterize the disorder as centered on the person.<ref name= "Greenberg 1999">Greenberg MT (1999). ''Attachment and Psychopathology in Childhood''. In Cassidy J and Shaver PR (Eds.) ''Handbook of Attachment: Theory, Research and Clinical Applications''. pp. 469–96. Guilford Press {{ISBN|1-57230-087-6}}</ref> Work by C.H. Zeanah<ref name="Zeanah et al. (2004)"/> 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.<ref name= "Main, M., & Hesse, E. (1990)">Main M, Hesse E (1990) "Parents' unresolved traumatic experiences are related to infants' insecure-disorganized/disoriented attachment status: Is frightened or frightening behavior the linking mechanism?"

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.<ref>DSM-V Proposed Draft.
