# Validated outcome measures for Separation Anxiety Disorder in early childhood

No single gold standard exists for studying Separation Anxiety Disorder (ICD-11 6B05) in early childhood. Robust designs triangulate a developmentally validated diagnostic interview (e.g. PAPA) with dimensional caregiver-report scales (Preschool Anxiety Scale, SCAS-P, CBCL 1½–5) and a clinician-rated impairment anchor, using multi-informant methods. Report psychometrics for your own sample's age band and language.

*Studying separation anxiety in the under-sixes demands instruments calibrated to the developmental reality that brief protest at parting is normal — and that the signal lies in intensity, persistence and impairment.*

## In short
There is no single gold standard for Separation Anxiety Disorder (ICD-11 **6B05**) in early childhood; researchers typically triangulate a structured diagnostic interview with a dimensional symptom scale and an impairment measure. The most defensible designs pair a developmentally validated diagnostic interview (such as the **PAPA** — Preschool Age Psychiatric Assessment) with caregiver-report dimensional scales (the **PAS** / Preschool Anxiety Scale, the **SCAS-P** preschool form, or the anxiety subscale of the **CBCL 1½–5**), plus a clinician-rated severity or global-impairment anchor. Because most informants are caregivers and teachers at this age, multi-informant and multi-method designs are essential to control for reporter bias.

## Measurement landscape for early childhood
**Diagnostic / criterion-anchored interviews**
- **PAPA (Preschool Age Psychiatric Assessment)** — interviewer-administered parent interview validated from ~2–5 years; widely used as the diagnostic reference for preschool anxiety.
- Age-extended structured interviews (e.g. K-SADS variants) where the lower age band has been validated for the sample.

**Dimensional caregiver-report scales**
- **Preschool Anxiety Scale (PAS / Spence preschool form)** — contains a dedicated separation-anxiety subscale, normed for ~2.5–6.5 years.
- **SCAS-P (preschool/parent version)** and the **CBCL 1½–5** anxiety-related syndrome scales for broadband screening and convergent validity.
- **ECBQ / temperament measures** used as covariates rather than outcomes.

**Impairment, severity and change**
- Clinician-rated global anchors (e.g. CGI-Severity/Improvement) and child/family impairment indices to separate symptom counts from functional burden — the construct that actually licenses a 6B05 designation.

For early-childhood research, prioritise instruments with published preschool norms, demonstrated test–retest and inter-informant reliability, and sensitivity to change for intervention trials. Report psychometrics for *your* sample's age band, language and jurisdiction rather than inheriting validation claims from older cohorts.

## The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from a scale, an app or a research instrument used in isolation. For collaborators designing early-childhood anxiety protocols, our structured clinician-administered assessment can serve as a complementary functional outcome alongside published measures. Explore [Separation Anxiety Disorder](/separation-anxiety-disorder), our [child psychology and behavioural therapy services](/child-psychology), and [how the AbilityScore® is established](/ask/what-is-the-abilityscore-and-how-is-it-calculated).

## Trusted sources
WHO ICD-11 entry for Separation Anxiety Disorder (6B05); WHO guidance on child mental health and functioning frameworks; AAP/HealthyChildren developmental and emotional-health resources. Always verify the validated age band and psychometric properties of any instrument against its primary publication.

**Next step —** Researchers planning an early-childhood anxiety study can [partner with the Pinnacle clinical research team](/research) to align outcome measures and functional endpoints.

This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
