Characteristics of disinhibited social engagement disorder

  • Children with this disorder have disinhibited social conduct. In other words, they don’t feel at all uncomfortable regarding the presence of strangers and immediately interact with them as if they knew them.
  • These behaviors make their relationships with other children and adults complicated.
  • This disorder appears during early childhood, between 9 months and 5 years of age. However, it can continue to persist in subsequent stages.

  • These children seek connection, even if it’s with strangers.

Diagnostic criteria

This is the diagnostic criteria for disinhibited social engagement disorder according to the DSM-V:

  1. Behavior that involves approaching strangers without distrust or hesitation.
  2. The child has gone through situations involving a lack of care or attachment regarding their main caregiver.
  3. The disorder appears between 9 months and 5 years of age.
  4. These behaviors must persist for at least 12 months. After the age of 4, the symptoms will involve constant attention-seeking and disproportionate expressions of affection.

Symptoms associated with disinhibited social engagement disorder

Most symptoms have to do directly with the child’s behavior regarding how they relate to others. Mainly, it has to do with how they relate to adults.

  • A lack of feelings of fear when it comes to strangers.
  • Children interact without inhibition with adults who aren’t their family members and who they don’t even know.
  • These children don’t often look for or need their parents or caregivers when in an unfamiliar environment.
  • A tendency to go off with strangers.
  • Verbally and physically affectionate behavior that exceeds their age and social norms.

Causes of disinhibited social engagement disorder

  1. The cause may be an attachment disorder during infancy where a child didn’t receive proper care and affection as a baby.
  2. Some theories also indicate there may be certain biological circumstances at play. These are associated with the child’s temperament and their regulation of affection. According to these theories, certain alterations in certain areas of the brain (hippocampus, amygdala, prefrontal cortex) may be responsible for these behavior problems. However, there’s still no confirmation that these theories are true.
  3. However, experts have observed various key causes of this disorder. For example, neglect and family violence. Living in an orphanage where there’s a lack of affection and frequent changes in main caregivers is also a major factor. In all of these cases, children are unable to establish healthy bonds with anyone. And, as a result, they may develop this disorder.


In these cases, it’s best to offer children a stable bond. Little ones with this disorder have a completely distorted model when it comes to relationships. So, therapists must work with parents as well as children in order to establish positive interaction between both parties.

In this case, the objective is to change the behavior of parents toward the child.

  • With parents, a professional will help them offer security, be available emotionally, and be stable attachment figures.
  • With the child, the professional will work on the reconstruction of their feelings of safety in order to reconstruct attachment in a healthy and positive way.
