# Standardised instruments for the sensory domain (ICF b2) in young children

Canonical: https://pinnacleblooms.org/ask/which-standardised-instruments-assess-the-sensory-developmental-domain-in-young-children
Publisher: Pinnacle Blooms Network / Bharath Healthcare Laboratories Private Limited

The sensory domain (ICF b2) in young children is assessed using validated, norm-referenced instruments — chiefly the Sensory Profile 2 (with Infant and Toddler editions), the Sensory Processing Measure (SPM-2), the Test of Sensory Functions in Infants, and the DeGangi–Berk TSI. Most are caregiver-report tools supplemented by clinician observation; none is diagnostic alone. Tool choice depends on age band, informant access and the research question, and findings should be interpreted within the ICF framework.

*When a young child startles at soft sounds or seeks out deep pressure, the right instrument turns those observations into a structured developmental picture.*

## In short
The [sensory domain](/sensory) — ICF *sensory functions (b2)* — is assessed in young children using a small set of validated, norm-referenced instruments, most administered as caregiver questionnaires supplemented by structured clinician observation. The most widely cited are the **Sensory Profile 2** (including the Infant/Toddler editions), the **Sensory Processing Measure (SPM-2)**, the **Test of Sensory Functions in Infants (TSFI)**, and the **DeGangi–Berk Test of Sensory Integration (TSI)**. No single tool is diagnostic; selection depends on age band, informant access and the clinical question.

## The instruments in current use
- **Sensory Profile 2 (Dunn)** — caregiver report across auditory, visual, tactile, movement, oral and behavioural sections; the **Infant Sensory Profile 2** (birth–6 months) and **Toddler Sensory Profile 2** (7–35 months) extend coverage to the youngest children, mapping responses to Dunn's quadrant model (registration, seeking, sensitivity, avoiding).
- **Sensory Processing Measure–2 (SPM-2)** — norm-referenced from infancy through adulthood, with home and early-care/preschool forms enabling cross-setting comparison; covers processing, praxis and social participation.
- **Test of Sensory Functions in Infants (TSFI)** — direct performance-based measure for 4–18 months, useful where a structured infant administration is preferred over report alone.
- **DeGangi–Berk TSI** — for ~3–5 years, sampling postural control, bilateral integration and reflex integration.
- **Adjuncts**: the **Sensory Integration and Praxis Tests (SIPT)** apply from ~4 years upward, and broader developmental batteries (e.g. Bayley) capture sensory-motor items within wider scales.

Most are caregiver-informant tools; psychometric strength rests on combining standardised scores with multi-setting observation rather than any isolated cut-off.

## Methodological notes for research use
Interpret sensory findings within the ICF framework rather than as a standalone label: b2 *sensory functions* describe body-function differences, which must be linked to activity and participation outcomes. Age-band fit matters — infant editions differ substantially from preschool forms in normative samples and constructs. Triangulate informant report with direct observation to mitigate rater bias, and check that the normative reference population is appropriate to an Indian cohort before generalising.

## The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under the care of a qualified clinician — never from a questionnaire score alone. Our AbilityScore® is a clinician-administered structured assessment that situates sensory findings against the child's own developmental baseline, drawing on 2.5 billion+ data points and 25 million+ therapy sessions across 70+ centres. For research partnership and instrument selection, our team pairs standardised measures with [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate) expertise. See how the measure works: [what the AbilityScore is and how it's calculated](/ask/what-is-the-abilityscore-and-how-is-it-calculated).
