Identification of Sensory Processing and Integration Symptom Clusters: A Preliminary Study

الملخص EN

Rationale.

This study explored subtypes of sensory processing disorder (SPD) by examining the clinical presentations of cluster groups that emerged from scores of children with SPD on the Sensory Processing 3-Dimension (SP-3D) Inventory.

Method.

A nonexperimental design was used involving data extraction from the records of 252 children with SPD.

Exploratory cluster analyses were conducted with scores from the SP-3D Inventory which measures sensory overresponsivity (SOR), sensory underresponsivity (SUR), sensory craving (SC), postural disorder, dyspraxia, and sensory discrimination.

Scores related to adaptive behavior, social-emotional functioning, and attention among children with different sensory modulation patterns were then examined and compared.

Results.

Three distinct cluster groups emerged from the data: High SOR only, High SUR with SOR, and High SC with SOR.

All groups showed low performance within multiple domains of adaptive behavior.

Atypical behaviors associated with social-emotional functioning and attention varied among the groups.

Implications.

The SP-3D Inventory shows promise as a tool for assisting in identifying patterns of sensory dysfunction and for guiding intervention.

Better characterization can guide intervention precision and facilitate homogenous samples for research.
