Note. Sensory scores were averaged across measures: Parent-report measures were from the Sensory Experiences Questionnaire and Sensory Profile; observational measures were from the Sensory Processing Assessment for Young Children and the Tactile Defensiveness and Discrimination Test–Revised. ASD = autism spectrum disorder; CGSQ = Caregiver Strain Questionnaire; DD = other developmental disabilities; f = factor; HCAS = Home and Community Activities Scale; HYPER = hyperreactivity; HYPO = hyporeactivity; M = mean; SD = standard deviation; SIRS = sensory interests, repetitions, and seeking behaviors.
