Sensory profile of children with Central Auditory Processing Disorder (CAPD).
Flávia Regina Ribeiro Cavalcanti Buffone, Eliane Schochat
PMID 35019061WHAT IT FOUND
Caregiver reports did not distinguish children with CAPD from children with typical auditory processing.
A moderate visual sensory difference appeared, but the groups were not separated.
Key findings
01The CAPD and normal CAP groups did not differ statistically on Child Sensory Profile 2 scores.
02In the CAPD group, sensory differences appeared in 8 of 13 Child Sensory Profile 2 results, including seeker and sensor quadrants, visual, touch, movement, and oral systems, and conduct and attention behaviors.
03The visual sensory section showed a moderate effect size of 0.44 between groups.

What it does not show
The study was cross-sectional, so it cannot show whether CAPD and sensory differences are causally linked. The study included only 60 children, with 23 in the CAPD group and 37 in the normal CAP group, so it may not detect small differences. The main sensory score comparison was not statistically significant, and the visual effect size was only a moderate descriptive finding. The Child Sensory Profile 2 was completed by caregivers and, as stated in the paper, does not diagnose sensory processing disorder. All participants came from two public schools, and many families had low per capita income and caregiver education, which may have influenced auditory and sensory results.
Declared interests
Financial support came from CAPES (23038.000877/2016-44). The supplied text does not report author conflicts of interest.
The easy way to misread this
Do not conclude that CAPD causes sensory processing disorder or that this study proved children with CAPD have a different sensory profile. The comparison between CAPD and normal CAP found no statistically significant difference, and the Child Sensory Profile 2 is not a diagnostic test.
