Disinhibited attachment disorder of childhood (DAD) according to the International Classification of Diseases (ICD-10), is defined as:

Disinhibited attachment disorder is a subtype of the ICD-10 category F94, "Disorders of social functioning with onset specific to childhood and adolescence". The other subtype of F94 is reactive attachment disorder of childhood (RAD – F94 .1).

Synonymous or similar disorders include Affectionless psychopathy and Institutional syndrome.

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

The DSM-IV distinguishes two categories of RAD: an inhibited subtype and a disinhibited subtype (in the DSM it is listed as 313.89 under infant diagnoses). The ICD-10 describes the former, emotionally withdrawn subtype as RAD and the latter subtype as Disinhibited Attachment Disorder (DAD) (Zeanah et al., 2004).

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).

In a study by Zeanah, (Zeanah et al., 2004) on reactive attachment disorder in maltreated toddlers, the criteria for DSM-IV disinhibited RAD (i.e. disinhibited attachment disorder) were:

For comparison, the criteria for DSM-IV inhibited RAD were:

The authors found that these two disorders were not completely independent; a few children may exhibit symptoms of both types of the disorder.
