F94 — Disorders of social functioning with onset specific to childhood and adolescence: facilitator sheet
Teaching objective
F94.0 requires normal or near-normal language competence alongside a consistent failure to speak in specific social situations where speech is expected. F94.1 and F94.2 each require both a characteristic pattern of abnormal social relatedness and a documented history of grossly inadequate care — persistent disregard of the child's basic emotional or physical needs, repeated changes of primary caregiver preventing stable attachments, or rearing in an institutional setting with too few caregivers for too many children. This etiological requirement is decisive: the pattern reflects the caregiving environment the child experienced, never a flaw in the child.

Worked example
Show scenario
A 5-year-old readily approaches and hugs unfamiliar adults at a family gathering, showing little apparent wariness of strangers. Her caregiving history is a single, stable placement with the same attentive foster family since infancy, with no documented history of neglect or repeated caregiver changes.
Reveal step 1
Step 1 — Check the behavioural pattern: indiscriminate friendliness toward unfamiliar adults is consistent with the surface presentation of F94.2.
Reveal step 2
Step 2 — Check the required caregiving history specifically: her placement history shows a single, stable, attentive caregiving environment since infancy, with no documented neglect or caregiver instability.
Reveal step 3
Step 3 — Weigh what this means: F94.2 specifically requires a documented history of grossly inadequate care; without it, the behavioural pattern alone is not sufficient.
Reveal step 4
Conclusion — This does not support F94.2; the required caregiving history is absent, so the friendliness is better understood as an individual temperament trait rather than a disorder of social functioning.
Comparison points
F94.1 and F94.2 are distinguished from ordinary shyness, wariness, or clinginess by the specific, required history of grossly inadequate care — the behavioural pattern alone, however unusual, is not sufficient without this documented history. F94.0 (elective mutism) is distinguished from a specific developmental disorder of speech and language (F80) or a pervasive developmental disorder (F84) by normal or near-normal language competence in the settings where the child does speak. F94 is distinguished from F93 by whether the presentation is a fear/worry-based emotional reaction (F93) or a social-functioning pattern rooted in the caregiving environment itself (F94).
Misconception prompt
Diagnosing an attachment disorder from behaviour alone, without the required caregiving history: "She's overly friendly with strangers, so that's an attachment disorder."
Ask the class why this reasoning fails before revealing the explanation below.
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.
Discussion prompts
Prompt 1
Explain why F94.1 and F94.2 both require a documented caregiving history, not just a behavioural pattern.
Prompt 2
Explain how F94.0 (elective mutism) is distinguished from a language disorder.
Summary
A selective failure to speak despite normal language ability (F94.0), or an abnormal social-relatedness pattern specifically tied to a documented history of grossly inadequate care (F94.1/F94.2) — never a flaw in the child.
