Infant-Toddler Sensory Profile (ITSP)


The ITSP provides a standard method for measuring a child’s sensory processing abilities and profiling the effect of sensory processing on functional performance in a child’s daily life. The profile is designed for children from birth to 36 months. Each item in this primary caregiver-report questionnaire describes children’s responses to various sensory experiences. Together, the 58 items assess six types of processing: (1) general, (2) auditory, (3) visual, (4) tactile, (5) vestibular, and (6) oral sensory. Certain patterns of performance are indicative of difficulties with sensory processing and performance. Internal consistency has a wide range, with alpha coefficients from 0.17 to 0.83. Test-retest reliability ranged from 0.74 to 0.86. Validity is acceptable as measured against the Infant-Toddler Symptom Checklist (ITSC; DeGangi et al. 1995). The ITSP was normed on a sample of 589 children of primary Caucasian descent, with approximately 100 children in each six-month age span. This assessment is used widely with diverse populations and is appropriate for children enrolled in RPG projects, because children who have experienced trauma can display sensory deficits.
