Triangulation across exposure, symptoms, relationship and functioning, mapped to ICF and ICD-11, is the standard.","answer_md":"*Studying developmental trauma in the early years demands instruments that capture relational rupture, regulation and recovery — not just symptom counts.*\n\n## In short\nResearch into Developmental Trauma in early childhood draws on a layered battery: trauma-exposure and event inventories, caregiver-report symptom scales, dyadic relationship and attachment measures, and broad developmental or socio-emotional outcome tools. Because no single instrument captures the construct, well-designed studies triangulate exposure, symptomatology, the caregiving relationship and functional development. Selection should always be anchored to the child's age band and the study's theoretical model.\n\n## Validated outcome measures commonly used\n**Trauma exposure and event history**\n- Traumatic Events Screening Inventory — Parent Report Revised (TESI-PRR)\n- Child PTSD measures adapted for young children, aligned to the DSM-5 preschool PTSD subtype and to ICD-11 PTSD / Complex PTSD constructs\n\n**Symptom and regulation outcomes (caregiver-report)**\n- Child Behavior Checklist (CBCL 1½–5) for internalising/externalising and the dysregulation profile\n- Brief Infant–Toddler Social and Emotional Assessment (BITSEA) and the ITSEA for socio-emotional competence and problem domains\n- Devereux Early Childhood Assessment (DECA) for resilience and protective factors\n\n**Dyadic, attachment and caregiving context**\n- Strange Situation Procedure and attachment Q-sort approaches for relationship security\n- Parenting Stress Index (PSI) and observational coding of caregiver sensitivity (e.g. CARE-Index style schemes)\n\n**Developmental functioning**\n- Bayley Scales of Infant and Toddler Development and the Ages & Stages Questionnaires (ASQ-3, ASQ:SE-2) as broad developmental and socio-emotional outcome anchors\n\nFor longitudinal designs, the value lies in repeating the same calibrated measures at fixed intervals so change — in regulation, attachment and development — is interpretable rather than noisy. Map every chosen instrument to the WHO ICF functioning framework and to ICD-11 constructs to keep findings translatable across sites and jurisdictions.\n\n## The Pinnacle way\nDevelopmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from a questionnaire or an online form; for research collaboration our clinician-administered structured assessment can sit alongside published instruments as a functional outcome anchor. Explore [the Developmental Trauma knowledge base](/developmental-trauma), see how [the AbilityScore is administered and calculated](/ask/what-is-the-abilityscore-and-how-is-it-calculated), and review our [research partnership pathways](/research). With 12 validated studies, 2.5 billion+ data points and 70+ centres across 4 states, Pinnacle offers a real-world measurement infrastructure for multi-site early-childhood trauma research.\n\n## Trusted sources\nWHO ICD-11 framing of PTSD and Complex PTSD; the WHO ICF model of functioning for outcome mapping; AAP and CDC guidance on early-childhood adversity and developmental surveillance; NICE recommendations on assessing post-traumatic stress in children.\n\n**Next step —** Planning a study on Developmental Trauma? [Open a research partnership with Pinnacle](/research) to align measures and access multi-site functional outcome data.\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare
