ICD-11 code : 6B44;
Preferred Label : Reactive attachment disorder;
ICD-11 definition : Reactive attachment disorder is characterized by grossly abnormal attachment behaviours
in early childhood, occurring in the context of a history of grossly inadequate child
care (e.g., severe neglect, maltreatment, institutional deprivation). Even when an
adequate primary caregiver is newly available, the child does not turn to the primary
caregiver for comfort, support and nurture, rarely displays security-seeking behaviours
towards any adult, and does not respond when comfort is offered. Reactive attachment
disorder can only be diagnosed in children, and features of the disorder develop within
the first 5 years of life. However, the disorder cannot be diagnosed before the age
of 1 year (or a developmental age of less than 9 months), when the capacity for selective
attachments may not be fully developed, or in the context of Autism spectrum disorder.;
