Initial Development of the Infant/Toddler Sensory Profile

Abstract

We report on initial development of the Infant/Toddler Sensory Profile; a parent questionnaire assessing a child's sensory processing abilities. Parents of 401 typically developing infants and toddlers completed the 81-item questionnaire. Findings suggest that 48 of 81 items best characterized sensory processing for children 7 to 36 months of age, whereas 36 items appeared relevant for children birth to 6 months of age. Principal component analysis for 7 to 36 month olds produced an 8-component structure accounting for 47% of score variance. Reliability analyses were consistent with clusters previously identified in Dunn's model of sensory processing for older children (Dunn, 1997a). Implications for future work include replication with a large national sample and with specific disability groups.

3D Cohort Study: The Integrated Research Network in Perinatology of Quebec and Eastern Ontario

“…The cohort comprises 2366 women recruited in the first trimester of pregnancy (8)(9)(10)(11)(12)(13)(14) …”

Alcohol consumption in a general antenatal population and child neurodevelopment at 2 years

“…First, children of women who binge drank before knowing about the pregnancy and then continued to drink at a lower level for the remainder of the pregnancy had an almost twofold increased likelihood of scoring low in sensation avoiding. Children with low scores for sensation avoiding are more likely to engage in disruptive behaviours as a coping strategy to reduce sensory input 28. Conduct problems such as these may accumulate in early childhood through exposure to stressful situations and possibly lead to problem behaviours later 41.…”

“…The Infant/Toddler Sensory Profile is a 48-item screen for sensory processing behaviours in daily experiences (ie, auditory, visual, tactile, vestibular and oral sensory processing) 28. Mothers rate the frequency of each behaviour (1 ‘almost always’ to 5 ‘almost never’), and scores are grouped to generate four quadrants: low registration (length/intensity of stimuli needed to respond), sensation seeking (level of interest and pleasure associated with sensory stimuli), sensory sensitivity (ability to notice sensory stimuli) and sensation avoiding (need to control amount/intensity of sensory stimuli).…”

Harnessing Teacher's Wisdom for Evidence-Based Practice: Standardization Data from the Sensory Profile School Companion

“…In previous factor analyses, Dunn and colleagues (Dunn and Brown, 1997;Dunn, 1999;Brown, Tollefson, et al, 2001;Dunn and Daniels, 2001;Dunn, 2002Dunn, , 2007 found patterns that have become known as the "quadrants" in Dunn's model of sensory processing (Dunn, 1997). With teachers as informants on the School Companion, it was important to identify what patterns might emerge.…”
