Attachment Disorders

      Abstract

      The ability to form attachments with other human beings is an essential skill that typically begins early in life. The parent/caregiver–child relationship is the first crucial relationship that an infant forms, and the health of this relationship has a profound effect on the child's social and emotional development. Children who form secure relationships with their parent or other primary caregiver have fewer internalizing and externalizing behaviors, are more socially competent, and have better-quality friendships. Conversely, children with attachment disorders exhibit a varying capacity to form and sustain relationships and demonstrate emotional depth, they and experience a higher level of peer conflict. Children with insecure attachments have a greater likelihood for physical health morbidities and impaired social, psychological, and neurobiological functioning extending into adulthood. It is crucial that pediatric nurse practitioners implement practice behaviors to better identify children at risk for attachment disorders and link them with appropriate interventions. This continuing education article will explore attachment; and attachment theory; and attachment disorders in terms of types, risk factors, consequences, and treatment and will also provide implications for practice.

      The ability to form attachments with other human beings is an essential skill that typically begins early in life. The parent/caregiver–child relationship is the first crucial relationship that an infant forms, and the health of this relationship has a profound effect on the child's social and emotional development (

It is crucial that pediatric nurse practitioners (PNPs) implement practice behaviors to better identify children at risk for attachment disorders and link them with appropriate interventions. This continuing education article will explore attachment; attachment theory; and attachment disorders in terms of types, risk factors, consequences, and treatment and will also provide implications for practice.

      ATTACHMENT AND ATTACHMENT THEORY

      John Bowlby, a British psychologist, revolutionized thinking about the infant–mother (primary caregiver) relationship and the importance and function of all close relationships (
      • Bretherton I.
      Bowlby's legacy to developmental psychology.
      ).

      ,
      • Bowlby J.
      Attachment and loss: Vol. 3. Loss: Sadness and depression.
      ) is credited with the formulation of attachment theory, which expanded the understanding of human development and the importance of relationships. Working with orphaned/homeless children in Europe after the World War II and charged with assessing their mental health, Bowlby concluded that to grow up mentally healthy, the infant and young child must experience a warm, intimate, and continuous relationship with his/her mother (or primary caregiver). This relationship should be one that both find satisfying and enjoyable (
      • Bowlby J.
      Maternal care and mental health.
      ). From his initial observations, Bowlby developed a psychological theory of human connection called attachment theory (
      • Bowlby J.
      A secure base.
      ). The fundamental tenets of attachment theory include the following: (a) human beings are designed to connect with others emotionally and to form intimate relationships; (b) the social and cognitive development of children is powerfully influenced by how they are treated by their parents, especially their mothers; and (c) early experiences can explain tendencies in later relationships (
      • Snyder R.
      • Shapiro S.
      • Treleaven D.
      Attachment theory and mindfulness.
      ). Attachment theory states that patterns of relating to others acquired in the early parent/caregiver–child relationship are internalized and form the basis from which individuals enter and also maintain other close relationships. Nondefensive, open communication between child and caregiver results in healthy patterns of relating to others. Conversely, miscommunication, especially deliberate miscommunication, whereby a caregiver attempts to falsify a child's actual experience, results in the development of abnormal behaviors and negatively affects an individual's subsequent relationships. Thus, the family relationships of those who grow up to be relatively stable and self-reliant are characterized by unfailing parental support when needed, steady encouragement toward developing autonomy, and open communication by caregivers that validate a child's actual experiences (

      • Ainsworth M.
      • Bell S.
      Attachment, exploration, and separation: Illustrated by the behavior of one-year-olds in a strange situation.

      • Main M.
      • Solomon J.
      Procedures for identifying infants as disorganized/disoriented during the Ainsworth Strange Situation.
      added a fourth category: disorganized (insecure). Avoidant, anxious, and disorganized are all types of insecure attachment. Human infants need a consistent nurturing relationship with one or more sensitive caregivers to develop into healthy individuals (

      • van der Veer R.
      From secure dependency to attachment: Mary Ainsworth's integration of Blatz's security theory into Bowlby's attachment theory.
      ). Infants are social beings from birth, and by the second half of the first year of life, infant attachment behaviors become focused on a single person or small number of caregivers. The infant who has a caregiver who is consistently responsive to his/her needs develops a secure attachment with this individual. From this secure base, the infant feels comfortable exploring; self-reliance develops. Autonomy throughout the course of life operates optimally because of supportive attachment relationships (
      • Bretherton I.
      Bowlby's legacy to developmental psychology.
      ). Insecure attachments are characterized by an infant who does not seek out his/her caregiver when distressed or an infant who has difficulty moving away from the caregiver, likely due to the caregiver exhibiting unresponsive, rejecting, inconsistent, or insensitive care (
      • Chambers J.
      The neurobiology of attachment: From infancy to clinical outcomes.
      ). Secure attachment has proven to have beneficial results for the child (
      • Chambers J.

      ); however, insecure attachment presents developmental risks for the child (

      ). Children with insecure attachment in infancy have shown an increased likelihood for impaired social, psychological, and neurobiological functioning over time, which leads to a vulnerability for these children to develop psychopathology during their lifetimes.
      These various patterns of attachment are deeply influenced by a caregiver's personal experiences, especially with their own parents or caregivers (

      • Bowlby J.
      A secure base.
      states that attachment can be negatively affected by adversity at any time and also affected by favorable influences at any time. Individuals have the capacity for earned security, a term describing how an individual with an insecure attachment style can learn and develop a secure attachment style over time (
      • Siegel D.
      • Hartzell M.
      Parenting from the inside out: How a deeper self-understanding can help you raise children who thrive.
      ). Supportive relationships and a capacity toward self-understanding are crucial to the ability to develop earned security (
      • Siegel D.
      • Hartzell M.
      Parenting from the inside out: How a deeper self-understanding can help you raise children who thrive.
      ). A parents’/caregivers’ abilities to learn to change their styles of attachment bode well for their children (

      Attachment theory and mindfulness.
      ).

      TYPES OF ATTACHMENT DISORDERS

      It is now widely accepted that in early childhood, attachment disorders result from inadequate caregiving environments and can manifest as two distinct clinical patterns, an emotionally withdrawn/inhibited phenotype and an indiscriminately social/disinhibited phenotype (
      • Zeanah C.
      • Gleason M.
      Annual research review: Attachment disorders in early childhood—Clinical presentation, causes, correlates and treatment.
      ). Recognizing the significant differences in the clinical disorders, the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V;
      American Psychiatric Association
      Diagnostic and statistical manual of mental disorders.
      ) designated two separate attachment disorders, reactive attachment disorder (RAD) and disinhibited social engagement disorder (DSED), to describe these clinical symptoms. Previously, in the DSM-IV, the two phenotypes were defined as subtypes of the same disorder, known as reactive attachment disorder (
      American Psychiatric Association
      Diagnostic and statistical manual of mental disorders.
      ). RAD and DSED, although both attachment disorders, differ in important ways: phenotype, correlates, course, and response to intervention (
      • Rutter M.
      • Kreppner J.
      • Sonuga-Barke E.
      Emanuel Miller Lecture: Attachment insecurity, disinhibited attachment, and attachment disorders: Where do research findings leave the concepts.
      ,
      • Zeanah C.
      • Gleason M.
      Annual research review: Attachment disorders in early childhood—Clinical presentation, causes, correlates and treatment.
      ). To meet the diagnostic criteria for either attachment disorder, the child must have experienced serious social neglect early in life and have a cognitive age of at least 9 months to ensure that the child is developmentally capable of forming attachments (
      American Psychiatric Association
      Diagnostic and statistical manual of mental disorders.
      ).
      Both attachment disorders are relatively rare. RAD can be found in young children exposed to severe neglect before being placed into foster care or raised in institutions. However, less than 10% of these children experiencing severe neglect will develop the disorder. Children developing RAD most often experience severe social neglect within the first months of life. Symptoms of RAD develop at a young age, between the ages of 9 months and 5 years (
      American Psychiatric Association
      Diagnostic and statistical manual of mental disorders.
      ). In young children, RAD is characterized by the absence of focused attachment behaviors directed toward a preferred caregiver; failure to seek and respond to comforting when distressed; decreased social and emotional reciprocity; stunted response to others; and disturbed emotional regulation, such as negative affect and unexplained fearfulness or irritability, even when interacting with familiar adults attempting to provide comfort (
      • Mikic N.
      • Terradas M.
      Mentalization and attachment representations: A theoretical contribution to the understanding of reactive attachment disorder.
      ;
      • Zeanah C.
      • Gleason M.
      Annual research review: Attachment disorders in early childhood—Clinical presentation, causes, correlates and treatment.
      ). Children with RAD may engage in self-soothing behaviors, exhibit discomfort in social interactions, and be aggressive toward peers (
      • Haugaard J.
      • Hazan C.
      Recognizing and treating uncommon behavioral and emotional disorders in children and adolescents who have been severely maltreated: Reactive attachment disorder.
      ; see Box 1 for DSM-V criteria). The diagnostic criteria for RAD focus more specifically on absent or aberrant attachment behaviors across settings rather than social behaviors (
      • Zeanah C.
      • Gleason M.
      Annual research review: Attachment disorders in early childhood—Clinical presentation, causes, correlates and treatment.
      ). The core deficit of the disorder is the demonstration of the absence of attachment behaviors. Thus, the diagnosis of RAD should include observations of how the child interacts with his/her primary caregiver, not only with unfamiliar adults (
      • Zeanah C.
      • Gleason M.
      Annual research review: Attachment disorders in early childhood—Clinical presentation, causes, correlates and treatment.
      ). Cognitive delays, language delays, and stereotypies, are common comorbidities with RAD (
      American Psychiatric Association
      Diagnostic and statistical manual of mental disorders.
      ). Depressive symptoms may also be seen in children with RAD. Children with RAD may have accompanying medical conditions such as severe failure to thrive, skin lesions, and severe hygiene concerns.
      Reactive attachment disorder diagnostic criteria
      • 1.
        Consistent pattern of inhibited, emotionally withdrawn behavior with adult caregivers (both must be met):
        • Child does not seek comfort when distressed AND
        • Child does not respond to comfort when distressed
      • 2.
        Social and emotional disturbance that is persistent (at least two must be met):
        • Responsiveness (social and emotional) to others is minimal
        • Limited positive affect
        • Periods of unexplained irritability, sadness, or fear evident even in nonthreatening interactions with adult caregivers
      • 3.
        Child has experienced a pattern of extreme insufficient care (at least one must be met):
        • Ongoing social neglect and lack of having basic emotional needs for comfort, stimulation, attention, and affection met by caregivers
        • Multiple changes of primary caregivers such that opportunities to form attachments are limited
        • Rearing in unusual settings that severely limit opportunities to form selective attachments
      • 4.
        Experiencing the pattern of insufficient care resulted in the symptoms listed in #1 and #2
      • 5.
        The symptoms in #1 and #2 are evident before age 5 years
      • 6.
        The child has a developmental age of at least 9 months
      • 7.
        The criteria for autism spectrum disorder are not met
      Note. Adapted from the
      American Psychiatric Association
      Diagnostic and statistical manual of mental disorders.
      .
      The aberrant social behaviors noted in young children with RAD can mimic those of autism spectrum disorder (ASD). RAD must be differentiated from ASD. Children meeting diagnostic criteria for RAD must have experienced severe social neglect; children with ASD will have rarely experienced this type of neglect. Children with both disorders may exhibit stereotypic behaviors such as rocking or flapping (
      American Psychiatric Association
      Diagnostic and statistical manual of mental disorders.
      ). Children with ASD often exhibit restricted interests and repetitive behaviors, whereas children with RAD do not, and, most notably, children with ASD show developmentally appropriate attachment behavior, whereas children with RAD do not.
      Although symptoms of RAD can persist for several years, caution must be taken when making the diagnosis in a child older than 5 years of age (
      American Psychiatric Association
      Diagnostic and statistical manual of mental disorders.
      ). Children with RAD typically respond well to intervention, and RAD often resolves completely with access to a stable and loving caregiver. Therefore, the prognosis for children affected by RAD appears to be dependent on the quality of caregiving after the serious neglect (
      American Psychiatric Association
      Diagnostic and statistical manual of mental disorders.
      ). However, children with RAD may exhibit continuing impairment in family and social relationships even when placed in an adequate caregiving environment (

      ).
      DSED is characterized by an inappropriate friendliness and approach to unfamiliar adults, lack of wariness of strangers, and a tendency to wander off with strangers (
      • Zeanah C.
      • Gleason M.
      Annual research review: Attachment disorders in early childhood—Clinical presentation, causes, correlates and treatment.
      ; see Box 2 for DSM-V criteria). Although slightly more prevalent than RAD, with about 20% of high-risk children developing the disorder, DSED is also rare (
      American Psychiatric Association
      Diagnostic and statistical manual of mental disorders.
      ). Children with DSED must experience severe social neglect early in life; there is no evidence that neglect after age 2 years is associated with development of the disorder. Children with DSED exhibit a lack of appropriate social and physical boundaries; they will interact with adult strangers in close proximity in a way that the adult perceives to be invasive. Verbal boundaries may also be violated by DSED children by asking overly intrusive and familiar questions of adult strangers. The core deficit in DSED is indiscriminate and unmodulated social behavior, particularly noted in initial approaches to and interaction with unfamiliar adults (
      • Zeanah C.
      • Gleason M.
      Annual research review: Attachment disorders in early childhood—Clinical presentation, causes, correlates and treatment.
      ). The DSED phenotype is expressed as aberrant social behavior. Numerous studies have reported this indiscriminant behavior in institutionalized (

      • Tarullo A.
      • Gunnar M.
      Disinhibited social behavior among internationally adopted children.
      ). These children may show focused attachment behaviors and preferential comfort seeking from familiar adults yet also continue to approach and engage strangers nonselectively.
      Disinhibited social engagement disorder diagnostic criteria
      • 1.
        Child exhibits a pattern of behavior involving actively approaching and interacting with unfamiliar adults and at least two of the following:
        • Decreased or absent hesitation in approaching and interacting with unfamiliar adults
        • Overly familiar verbal or physical behavior
        • Does not check back with adult caregiver after venturing away, even in strange settings
      • 2.
        The behaviors in #1 are not the result of impulsivity (as in attention deficit hyperactivity disorder) but include socially disinhibited behavior
      • 3.
        Child has experienced a pattern of extreme insufficient care and at least one of the following:
        • Ongoing social neglect and lack of having basic emotional needs for comfort, stimulation, attention, and affection met by caregivers
        • Multiple changes of primary caregivers such that opportunities to form attachments are limited
        • Rearing in unusual settings that severely limits opportunities to form selective attachments
      • 4.
        Experiencing the pattern of insufficient care resulted in the symptoms listed in #1 and #2
      • 5.
        The child has a developmental age of at least 9 months
      Note. Adapted from the
      American Psychiatric Association
      Diagnostic and statistical manual of mental disorders.
      .
      There are symptoms of DSED that overlap with those of attention deficit hyperactivity disorder (ADHD). The socially inhibited behavior of DSED must be distinguished from the impulsivity of ADHD. Although disinhibition may be common to both ADHD and RAD, studies suggest that the behavior may result from distinctly different underlying pathologic mechanisms (

      Impaired neural reward processing in children and adolescents with reactive attachment disorder: A pilot study.
      suggest that a more severe dopaminergic dysfunction exists in children with DSED than in those with ADHD.
      As with RAD, DSED may co-occur with language delays, cognitive delays, and stereotypies (
      American Psychiatric Association
      Diagnostic and statistical manual of mental disorders.
      ). DSED is predictive of functional impairment, difficulties forming close relationships, and more need for special education services due to the social, cognitive, and behavioral abnormalities of the disorder (

      • Zeanah C.

      • Nelson C.
      • Guthrie D.
      A randomized controlled trial of foster care vs. institutional care for children with signs of reactive attachment disorder.
      ). Other signs of severe neglect may be noted, such as malnutrition. Unlike RAD, symptoms of DSED may persist even when neglect concerns have been alleviated. DSED may be seen in children who have suffered social neglect who lack attachments or whose attachments to their caregivers vary from disturbed to secure (
      American Psychiatric Association
      Diagnostic and statistical manual of mental disorders.
      ). DSED is less responsive to a normative caregiving environment than RAD. Although improving the caregiving environment can moderate the course of DSED, some children show persistent signs of the disorder extending into adolescence.

      RISK FACTORS

      Experiencing serious emotional neglect or insufficient care early in life (before age 3 years) is the essential element for the development of attachment disorders (
      American Psychiatric Association
      Diagnostic and statistical manual of mental disorders.
      ). Factors that interfere with a caregiver's ability to consistently meet the emotional and physical needs of an infant are risk factors for the development of attachment disorders. Factors that impede the availability of a consistent caregiver are also risk factors for attachment disorders. See Box 3 for risk factors.
      Factors that interfere with a caregiver's ability to consistently meet the emotional and physical needs of an infant are risk factors for the development of attachment disorders.
      Historically, attachment disorders were studied in institutionalized children deprived of a consistent primary caregiver. The link between attachment disorders and institutionally raised infants has been firmly established (

      ). As we begin to understand more about the neurodevelopmental processes involved in attachment, a shift has been made to note the increased importance of the prenatal period (
      • Chambers J.
      The neurobiology of attachment: From infancy to clinical outcomes.
      ). Although psychological interaction between mother and infant does not develop prenatally, studies show that an infant is born with a preference for his/her mother's smell, milk, and voice (
      • Vaglio S.
      Chemical communication and mother-infant recognition.

      • Hayes L.
      • Goodman S.
      • Carlson E.
      Maternal antenatal depression and infant disorganized attachment at 12 months.
      ). Interventions to ensure that prenatal depression does not continue into postpartum depression are crucial. Studies indicate that higher-quality caregiving in the first 3 months of life can decrease the risk of disorganized attachment due to prenatal depression (

      • Chambers J.
      The neurobiology of attachment: From infancy to clinical outcomes.
      ).
      Experiencing child maltreatment places a child at risk for attachment disorders. Any one type of child maltreatment—sexual abuse, physical abuse, emotional abuse, and neglect (physical and emotional)—rarely occurs in isolation, placing a child at yet increased risk of experiencing insufficient care (
      • Jackson A.
      • Kissoon N.
      • Greene C.
      Aspects of abuse: Recognizing and responding to child maltreatment.
      ). Familial psychosocial risk factors diminish a caregiver's ability to adequately meet the needs of a young child, placing the child at increased risk of developing an attachment disorder as well as experiencing child maltreatment (

      ,
      • Zeanah C.

      ). These familial psychosocial risk factors include parental mental health concerns, parental drug and/or alcohol concerns, intimate partner violence, and parental separation and divorce. Placement into foster care, a potential consequence of experiencing child maltreatment, also increases the risk of young children developing an attachment disorder, especially if multiple foster care placement/disruptions occur. Symptoms of attachment disorders, especially DSED, may be more strongly related to the number of placements into foster care or the number of disruptions while in foster care than to the severity of child maltreatment experienced because of both resulting in the lack of a stable, consistent caregiver (

Sex, ethnicity, and time in foster care did not seem to be related to the type of RAD exhibited by the child. Maternal mental health disorders were associated with both inhibited and disinhibited RAD, whereas maternal substance abuse was associated with only the disinhibited type (

      CONSEQUENCES

      It is important to understand that the symptoms of attachment disorders and the long-term consequences exist on a continuum. Children with attachment disorders exhibit a varying capacity to form and sustain relationships and demonstrate emotional depth (

      Practice parameter for the assessment and treatment of children and adolescents with reactive attachment disorder and disinhibited social engagement disorder.
      ). Children with attachment disorders tend to develop superficial relationships and experience a higher level of peer conflict. Trust is essential for the development of secure, healthy relationships. A sense of trust in family and peers is primarily based on environmental factors (

      ). Children with attachment disorders have problems with trust. Those with the RAD type have difficulty truly trusting anyone, even a kind, consistent caregiver, whereas those with DSED trust indiscriminately, and this poor judgement places them at increased risk for physical, sexual, and emotional harm (

      • Englund M.

      • Chambers J.
      The neurobiology of attachment: From infancy to clinical outcomes.
      ). By diagnostic criteria, individuals with attachment disorders (RAD or DSED) have experienced severe emotional and or physical neglect very early in life. These individuals have experienced profound trauma, very similar to that experienced by participants of the Adverse Childhood Experiences Study, where childhood exposure to child maltreatment, domestic violence, caregiver drug or alcohol concerns, caregiver mental health diagnosis, and parental separation and divorce were linked to a variety of negative adult physical and mental health consequences in a dose-related exposure gradient (

      ).

      TREATMENT

      The most important intervention for young children diagnosed with RAD or DSED is ensuring a consistent, sensitive caregiver who is emotionally invested in the child and emotionally available to the child (
      • Zeanah C.
      • Chesher T.
      • Boris N.
      American Academy of Child and Adolescent Psychiatry Committee on Quality Issues
      Practice parameter for the assessment and treatment of children and adolescents with reactive attachment disorder and disinhibited social engagement disorder.
      ). Children with RAD do not have secure attachments to adult caregivers. Although some children with DSED will have healthy secure attachments to foster or adoptive parents, many have no true secure attachments, only insecure attachments. In children with RAD or DSED who lack secure attachments, forming robust and healthy attachments is the first priority of treatment (
      • Zeanah C.
      • Chesher T.
      • Boris N.
      American Academy of Child and Adolescent Psychiatry Committee on Quality Issues
      Practice parameter for the assessment and treatment of children and adolescents with reactive attachment disorder and disinhibited social engagement disorder.
      ). The child and caregiver should be linked with a pediatric mental health provider skilled in the assessment and treatment of attachment disorders. Therapy will focus on the tenet that the caregiver's sensitively attuned behavior serves to help the child develop an internal sense of security (
      • Zeanah C.
      • Chesher T.
      • Boris N.
      American Academy of Child and Adolescent Psychiatry Committee on Quality Issues
      Practice parameter for the assessment and treatment of children and adolescents with reactive attachment disorder and disinhibited social engagement disorder.
      ). First, the mental health provider will work through the caregiver, helping the caregiver manage the child's behavior and addressing the caregiver's own feelings of anxiety, frustration, or anger with the difficult-to-connect-with child. Caring for a child who does not connect with the caregiver can be very labor intensive and unrewarding. It is not unusual for a caregiver to feel disconnected to the child and to feel anger or frustration (
      • Zeanah C.
      • Chesher T.
      • Boris N.
      American Academy of Child and Adolescent Psychiatry Committee on Quality Issues
      Practice parameter for the assessment and treatment of children and adolescents with reactive attachment disorder and disinhibited social engagement disorder.
      ). To further interfere with the child's attachment behaviors, discipline can become harsh and disciplinarian. The mental health provider will assist the caregiver in working through these feelings and becoming consistently emotionally available to the child. Therapy with the child and primary caregiver, dyadic interactive therapy, is often used to address symptoms of RAD (
      • Zeanah C.
      • Chesher T.
      • Boris N.
      American Academy of Child and Adolescent Psychiatry Committee on Quality Issues
      Practice parameter for the assessment and treatment of children and adolescents with reactive attachment disorder and disinhibited social engagement disorder.
      ). For young children with DSED, limiting contacts beyond immediate family for the first several months after a new placement may be helpful in reducing or eliminating indiscriminate behavior (

      • Chesher T.
      • Boris N.
      American Academy of Child and Adolescent Psychiatry Committee on Quality Issues
      Practice parameter for the assessment and treatment of children and adolescents with reactive attachment disorder and disinhibited social engagement disorder.
      ). Psychopharmacological intervention is not indicated for RAD or DSED. However, children with comorbid disorders, such as ADHD, anxiety, or mood disorders, may benefit from medication to treat these disorders. Nontraditional attachment therapies that involve non-contingent physical restraint or coercion, “reworking” of trauma, or promotion of regression for “reattachment” have no empirical support and have been associated with serious harm, even six child deaths (

      ).

      IMPLICATIONS FOR PRACTICE

      Pediatric health care provides a unique vehicle for the early identification of children at risk for attachment disorders and, therefore, an avenue to prevention. Attachment disorders typically begin developing very early in life. Infants and toddlers require frequent health care visits before the age of 2 years. This affords the PNP with an opportunity to identify those families with psychosocial dysfunction that predisposes their child/children to developing an attachment disorder, provide necessary intervention to address concerns, and prevent the development of an attachment disorder. The consistent encouragement of positive parenting practices, beginning with the first newborn well-child visit, is crucial (
      • Seay A.
      • Freysteinson W.
      • McFarlane J.
      Positive parenting.
      ), and should include screening for maternal postpartum depression, assessment for any compromise of mother/infant bonding and maternal ability to care for the infant, and linking with appropriate mental health resources (
      • Chambers J.
      The neurobiology of attachment: From infancy to clinical outcomes.
      ). Encourage parents/caregivers to talk to their babies, stress the importance of eye contact, and holding their babies for feedings. Discuss cuddling—touch is important for an infant's development. As children grow and develop, providers should make sure that parents understand realistic behavioral expectations for each developmental level. Nonphysical methods of discipline should be encouraged (

      ), and parental praise of good behavior, which is a powerful tool in shaping positive behavior (
      • Seay A.
      • Freysteinson W.
      • McFarlane J.
      Positive parenting.
      ), should be emphasized.
      PNPs must know patients psychosocial histories as thoroughly as their medical histories (Box 4;
      • Hornor G.
      Child maltreatment: Screening and anticipatory guidance.
      ). They should be open and without judgement when screening and should explain that these are problems that affect many families and that all families are screened for these concerns. It is also important that they understand a parent/caregiver's trauma history and their resolution of that trauma exposure. Parent/caregiver processing of their own trauma histories is important for them to be a safe haven for the child (
      • Walker J.
      The use of attachment theory in adoption and fostering.
      ). Families should be linked with appropriate interventions to address identified concerns, and providers should monitor parental follow-through with suggested interventions (
      • Hornor G.
      Child maltreatment: Screening and anticipatory guidance.
      ). If screening results show a concern for child maltreatment, a report to child protective services is always indicated. The goal of child protective services involvement is to ensure the safety of the child while strengthening the family unit to better care for the child (

      • Font S.

      Unfortunately, there are situations in which egregious abuse and/or neglect have occurred, necessitating placement into foster or kinship care. These children are at increased risk for the development of an attachment disorder (
      • Follan M.
      • McNamara M.
      A fragile bond: Adoptive parents’ experiences of caring for children with a diagnosis of reactive attachment disorder.
      ). Each subsequent change in placement, return to parental care, re-entry into foster care, or disruption of a foster or kinship placement, which results in placement with yet another caregiver, increases that child's risk of developing an attachment disorder. The PNP working with children in kinship and/or foster care must not only assess the safety of the child in that care setting but also ensure that the caregiver is provided with the necessary resources to successfully care for the child (
      • Hornor G.
      Children in foster care: What the forensic nurse needs to know.
      ). Discuss the potential impact of the child's trauma exposure on his/her behavior. Stress the importance of consistent, developmentally appropriate behavioral expectations and the importance of discipline that is not physically or emotionally harsh. Link the child with the appropriate mental health interventions to meet his/her needs, such as trauma-focused mental health care.
      The PNP may also be providing care to children who have been adopted. Not all adopted children are at risk for attachment disorders. However, there are factors that increase the risk for attachment disorders in adopted children such as adoption at an older age, international adoption with a history of institutional care, multiple foster care placements, and severe social neglect (
      • Follan M.
      • McNamara M.
      A fragile bond: Adoptive parents’ experiences of caring for children with a diagnosis of reactive attachment disorder.
      ). Other children are also at high risk for attachment disorders, such as those who have experienced multiple changes of placement between biological, foster, and kinship care and even those who have remained with biological parents but have suffered severe social neglect in that setting (
      • Smyke A.
      Adoptive parents can be unprepared for the challenges in caring for children with reactive attachment disorder.
      ).
      The PNP must be able to recognize symptoms of attachment disorders in these high-risk children. Unfortunately, there are no validated screening tools for either RAD or DSED. When the PNP is caring for a young child with a history of severe social neglect of any source, a few screening questions should be asked to determine if the child shows appropriate attachment behaviors with their primary caregivers and shows appropriate reticence with strangers (

      ). See Box 5 for attachment screening questions. The PNP should note that a history of recent and severe neglect should exist to consider RAD in a child older than 5 years of age (

      Pediatric health care providers, especially PNPs, can make a difference in the lives of children at risk for the development of attachment disorders. By understanding the importance of attachment and embracing practice behaviors that address the importance of consistent loving caregiving, the PNP can help prevent attachment disorders in all children. Screening all families for psychosocial risk factors that can impede secure attachment and providing appropriate intervention to address identified risk factors can help to prevent attachment disorders in a potentially higher-risk population. Finally, PNPs must be aware of symptoms of insecure attachment and understand that children who have experienced severe social neglect at a young age are at particular risk for the development of attachment disorders. Timely linkage of these children and caregivers with appropriate treatment for attachment disorders can be the crucial first step in healing and forming lifelong secure and healthy relationships.
      By understanding the importance of attachment and embracing practice behaviors that address the importance of consistent loving caregiving, the PNP can help prevent attachment disorders in all children.
