Diagnosing an attachment disorder from behaviour alone, without the required caregiving history

1. The tempting shortcut
"She's overly friendly with strangers, so that's an attachment disorder."

2. Stop and think
Before you read on: what is wrong with this reasoning? Try to answer in your own words, then reveal the explanation below.

3. Reveal — why it fails
F94.1 (reactive attachment disorder) and F94.2 (disinhibited attachment disorder) both specifically require a documented history of grossly inadequate care — persistent disregard of the child's basic needs, repeated changes of primary caregiver, or institutional rearing — as part of their diagnostic criteria, not merely an unusual behavioural pattern. A child's temperament (shyness, sociability, wariness of strangers) varies widely for ordinary reasons unrelated to caregiving adequacy. Diagnosing an attachment disorder from behaviour alone, without this specific history, risks mislabelling ordinary temperament as pathology and, worse, can wrongly imply inadequate caregiving where none occurred.

4. Reveal — the better reasoning rule
- Is there a documented history of grossly inadequate care — persistent neglect, repeated caregiver changes, or institutional rearing — specifically established in the vignette, or only an unusual behavioural pattern?
- Could a stable, consistently attentive caregiving history make ordinary temperament (shyness, sociability) a more likely explanation than a disorder of social functioning?
- The behavioural pattern and the caregiving history are both required together; neither is sufficient alone.
Corrective example: In F94's boundary case, a 5-year-old's indiscriminate friendliness toward unfamiliar adults, despite a single, stable, attentive caregiving placement since infancy with no documented neglect, does not meet F94.2 — the required caregiving history is absent, so the friendliness is better understood as an individual temperament trait.
