Screening and diagnostic pathway for Developmental Trauma under 7
Developmental Trauma in under-7s has no single test and is not a standalone diagnosis. The recommended pathway is structured developmental and adversity screening, a multi-domain trauma-informed clinician assessment, exclusion of medical and neurodevelopmental mimics, then a dyadic, caregiver-mediated support plan.
In this answer 4 sections
A young child carries trauma in their behaviour and body long before they can name it — the clinician's task is to recognise the pattern and route it correctly.
In short
There is no single diagnostic test for Developmental Trauma in the under-7s, and it is not a standalone ICD category — it presents as dysregulation, attachment disruption and developmental derailment following chronic adversity. The recommended pathway is structured screening → multi-domain developmental and trauma-informed assessment → formulation that excludes medical and neurodevelopmental mimics. Universal developmental surveillance at every well-child visit, with caregiver-context history, is the entry point.
The pathway, in brief
1. Screen. Use validated developmental surveillance (AAP-style schedule) plus a trauma/adversity exposure screen and caregiver-relationship history. Probe sleep, feeding, regulation, startle, and dissociation — not just milestones.
2. Assess across domains. A trauma-informed, clinician-administered evaluation covering communication, cognition, motor, social-emotional and regulatory functioning, with direct caregiver-child interaction observation. Map functioning against the WHO ICF model rather than chasing a single label.
3. Exclude mimics. Distinguish from primary autism, ADHD, global delay, hearing loss and medical causes — these co-occur and overlap. Red flags for medical urgency (seizures, regression) warrant prompt paediatric/neurology referral first.
4. Formulate and support. Build a relational, dyadic intervention plan; trauma responses in early childhood are highly responsive to caregiver-mediated support.
The Pinnacle way
AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from a form or screen alone. Our Developmental Trauma pathway pairs a structured, clinician-administered profile (how the AbilityScore® works) with dyadic child psychology and behaviour therapy, drawing on 2.5 billion+ data points across 70+ centres.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Persistent dysregulation, attachment disruption, sleep and feeding disturbance, exaggerated startle or dissociation following chronic adversity — alongside developmental derailment that doesn't fit a single neurodevelopmental label.
In everyday life
Always pair the developmental screen with a caregiver-relationship and adversity history; in early childhood the dyad, not the child alone, is the unit of assessment.

Bring your questions to a first visitQuestions families ask
Is Developmental Trauma a formal diagnosis in young children?
It is not a standalone ICD category. It describes a pattern of dysregulation, attachment disruption and developmental derailment following chronic early adversity, and is captured through trauma-informed formulation alongside related ICD-11 codes, not a single test.
How is it distinguished from autism or ADHD?
Through multi-domain assessment, adversity history and observation of caregiver-child interaction. These conditions overlap and co-occur, so the pathway deliberately excludes neurodevelopmental and medical mimics before formulating.
When should I refer urgently?
Any regression, suspected seizures or acute safeguarding concern warrants prompt paediatric, neurology or child-protection referral first, ahead of a therapy-led pathway.
