Other diagnoses available for selection on survey and number endorsed within the full analytic cohort of 162 children: 1 child with learning disability, 4 children with developmental disability, 2 children with dyslexia, 4 children with sensory integration disorder, 4 children with epilepsy, 7 children with anxiety disorder.
IQ score of 70 is used to determine intellectual disability.
Range, 0 to 108; raw score of 83 is equivalent to the expressive language of a child aged 4 years.
Range, 0 to 76; higher score indicates greater over-responsivity to common sensory experiences.
Range, 0-60; greater anxiety indicated by higher score.
