Disinhibited attachment disorder

The other subtype of F94 is reactive attachment disorder of childhood (RAD – F94.1).

Within the ICD-10 category scheme, disinhibited attachment disorder specifically excludes Asperger syndrome (F84.5), hospitalism in children (F43.2), and attention deficit hyperactivity disorder (F90.-).

Generally, the DSM-IV criteria for the inhibited subtype of RAD were generated by studies done on children who were maltreated or abused.

Criteria for the DSM-IV disinhibited subtype of RAD were based on research on children raised in institutions (Zeanah, 1996).

This is largely based on the fact that inhibited subtype of RAD is more prevalent in maltreated children, and the disinhibited subtype of RAD is more prevalent in children raised in institutions (Zeanah, 2000).
