Separation anxiety disorder

Separation anxiety disorder (SAD) is an anxiety disorder in which an individual experiences excessive anxiety regarding separation from home and/or from people to whom the individual has a strong emotional attachment (e.g., a parent, caregiver, significant other, or siblings). Separation anxiety is a natural part of the developmental process. It is most common in infants and little children, typically between the ages of six to seven months to three years, although it may pathologically manifest itself in older children, adolescents and adults. Unlike SAD (indicated by excessive anxiety), normal separation anxiety indicates healthy advancements in a child's cognitive maturation and should not be considered a developing behavioral problem.[1][2]

Separation anxiety disorder

According to the American Psychiatric Association (APA), separation anxiety disorder is an excessive display of fear and distress when faced with situations of separation from the home and/or from a specific attachment figure. The anxiety that is expressed is categorized as being atypical of the expected developmental level and age.[3] The severity of the symptoms ranges from anticipatory uneasiness to full-blown anxiety about separation.[4]


SAD may cause significant negative effects within areas of social and emotional functioning, family life, and physical health of the disordered individual.[3] The duration of this problem must persist for at least four weeks and must present itself before a child is eighteen years of age to be diagnosed as SAD in children, but can now be diagnosed in adults with a duration typically lasting six months in adults as specified by the DSM-5.[5]

Background[edit]

The origins of separation anxiety disorder stem from attachment theory which has roots in the attachment theories both of Sigmund Freud and John Bowlby. Freud's attachment theory, which has similarities to learning theory, proposes that infants have instinctual impulses, and when these impulses go unnoticed, it traumatizes the infant.[6] The infant then learns that when their mother is absent, this will be followed by a distressing lack of gratification, thus making the mother's absence a conditioned stimulus that triggers anxiety in the infant who then expects their needs to be ignored.[7] The result of this association is that the child becomes fearful of all situations that include distance from their caregiver.


John Bowlby's attachment theory also contributed to the thinking process surrounding separation anxiety disorder. His theory is a framework in which to contextualize the relationships that humans form with one another. Bowlby suggests that infants are instinctively motivated to seek proximity with a familiar caregiver, especially when they are alarmed, and they expect that in these moments they will be met with emotional support and protection.[8] He poses that all infants become attached to their caregivers, however, there are individual differences in the way that these attachments develop. There are 4 main attachment styles according to Bowlby; secure attachment, anxious-avoidant attachment, disorganized attachment, and anxious-ambivalent attachment. Anxious-ambivalent attachment is most relevant here because its description, when an infant feels extreme distress and anxiety when their caregiver is absent and does not feel reassured when they return, is very similar to SAD.

Signs and symptoms[edit]

Academic setting[edit]

As with other anxiety disorders, children with SAD tend to face more obstacles at school than those without anxiety disorders. Adjustment and relating school functioning have been found to be much more difficult for anxious children.[9] In some severe forms of SAD, children may act disruptively in class or may refuse to attend school altogether. It is estimated that nearly 75% of children with SAD exhibit some form of school refusal behavior.[3]


There are several possible manifestations of this disorder when the child is introduced into an academic setting.[10] A child with SAD may protest profusely upon arrival at school. They might have a hard time saying goodbye to their parents and exhibit behaviors like tightly clinging to the parent in a way that makes it nearly impossible for the parent to detach from them. They might scream and cry but in a way that makes it seem as though they were in pain. The child might scream and cry for an extended period of time after his or her parents are gone (for several minutes to upwards of an hour) and refuse to interact with other children or teachers, rejecting their attention. They might feel an overwhelming need to know where their parents are and that they are okay.


This is a serious problem because, as children fall further behind in coursework, it becomes increasingly difficult for them to return to school.[11]


Short-term problems resulting from academic refusal include poor academic performance or decline in performance, alienation from peers, and conflict within the family.[3]


Although school refusal behavior is common among children with SAD, it is important to note that school refusal behavior is sometimes linked to generalized anxiety disorder or possibly a mood disorder.[12] That being said, a majority of children with separation anxiety disorder have school refusal as a symptom. Up to 80% of children who refuse school qualify for a diagnosis of separation anxiety disorder.[13]

Home setting[edit]

Symptoms for SAD might persist even in a familiar and/or comfortable setting for the child, like the home.[10] The child might be afraid to be in a room alone even if they know that their parent is in the next room over. They might fear being alone in the room, or going to sleep in a dark room. Problems might present themselves during bedtime, as the child might refuse to go to sleep unless their parent is near and visible. During the day, the child might "shadow" the parent and cling to their side.

Workplace[edit]

Just how SAD affects a child's attendance and participation in school, their avoidance behaviors stay with them as they grow and enter adulthood. Recently, "the effects of mental illness on workplace productivity have become a prominent concern on both the national and international fronts".[14] In general, mental illness is a common health problem among working adults, 20% to 30% of adults will suffer from at least one psychiatric disorder.[14] Mental illness is linked to decreased productivity, and with individuals diagnosed with SAD their levels at which they function decreases dramatically resulting in partial work-days, increase in number of total absences, and "holding back" when it comes to carrying out and completing tasks.[14][15]

Mechanism[edit]

Preliminary evidence shows that heightened activity of the amygdala may be associated with symptoms of separation anxiety disorder. Defects in the ventrolateral and dorsomedial areas of the prefrontal cortex are also correlated to anxiety disorders in children.[27]

Recurrent excessive distress when anticipating or experiencing separation from home or from major attachment figures

Persistent and excessive worry about losing major attachment figures or about possible harm to them, such as illness, injury, disasters, or death

Persistent and excessive worry about experiencing an untoward event (e.g., getting lost, being kidnapped, having an accident, becoming ill) that causes separation from a major attachment figure

Persistent reluctance or refusal to go out, away from home, to school, to work, or elsewhere because of fear of separation

Persistent and excessive fear of or reluctance about being alone or without major attachment figures at home or in other settings

Persistent reluctance or refusal to sleep away from home or to go to sleep without being near a major attachment figure

Repeated nightmares involving the theme of separation

Repeated complaints of physical symptoms (e.g., headaches, stomachaches, nausea, vomiting) when separation from major attachment figures occurs or is anticipated

Treatment[edit]

Non-medication based[edit]

Non-medication based treatments are the first choice when treating individuals diagnosed with separation anxiety disorder.[4] Counseling tends to be the best replacement for drug treatments. There are two different non-medication approaches to treat separation anxiety. The first is a psychoeducational intervention, often used in conjunction with other therapeutic treatments.[4] This specifically involves educating the individual and their family so that they are knowledgeable about the disorder, as well as parent counseling and guiding teachers on how to help the child.[4][45] The second is a psychotherapeutic intervention when prior attempts are not effective. Psychotherapeutic interventions are more structured and include behavioral, cognitive-behavioral, contingency, psychodynamic psychotherapy, and family therapy.[4]

Epidemiology[edit]

Anxiety disorders are the most common type of psychopathology to occur in today's youth, affecting from 5–25% of children worldwide.[3] Of these anxiety disorders, SAD accounts for a large proportion of diagnoses. SAD may account for up to 50% of the anxiety disorders as recorded in referrals for mental health treatment.[3] SAD is noted as one of the earliest-occurring of all anxiety disorders.[5] Adult separation anxiety disorder affects roughly 7% of adults, though it has also been shown to occur in between 23-42% of adults in clinical samples.[26] It has also been reported that the clinically anxious pediatric population are considerably larger. For example, according to Hammerness et al. (2008) SAD accounted for 49% of admissions.[61]


Research suggests that 4.1% of children will experience a clinical level of separation anxiety. Of that 4.1% it is calculated that nearly a third of all cases will persist into adulthood if left untreated.[3] Research continues to explore the implications that early dispositions of SAD in childhood may serve as risk factors for the development of mental disorders throughout adolescence and adulthood.[59]


It is presumed that a much higher percentage of children suffer from a small amount of separation anxiety, and are not actually diagnosed. Multiple studies have found higher rates of SAD in girls than in boys, and that paternal absence may increase the chances of SAD in girls.[62]
