Sensory processing and its relationship with children's daily life participation

Abstract

Aims: To investigate whether children with probable or definite differences in sensory processing (SP) had participation restrictions, and the relationship between Short Sensory Profile (SSP) scores and children's participation. Methods: The participants were parents of 64 children (mean age 8 years 1 month); 36 with potential impairments in regulating sensory input and filtering out unnecessary stimuli (29 boys, 7 girls) and 28 with typical SP abilities (25 boys, 3 girls). Parents completed the SSP and Participation in Childhood Occupations Questionnaire (PICO-Q). The SSP score was used to categorize children as potential SP impairment group and typical SP ability group. Results: Children categorized as having probable or definite differences in SP exhibited significantly lower participation levels and enjoyment than children categorized as having typical SP abilities. However, participation frequency between both groups was similar. Six out of the seven SP impairment types had small to moderate correlations with children's participation (r = 0.25-0.48, p < 0.05). Multiple regression analyses indicated that only three impairment types (Underresponsive/Seeks Sensation, Low Energy/Weak, and Visual/Auditory Sensitivity) were significant predictors of PICO-Q participation domains. Conclusions: The results suggest that children with potential SP impairments have restrictions in the degree of participation and enjoyment. Three SP types were related to specific participation domains, but they explained a small amount of variance or none in some participation domains. Other variables should be considered to identify determinants of children's participation.
