Note. ASD = autism spectrum disorder; rcorr = Corrected item-total correlation; SSP = Short Sensory Profile; TAC = Tactile sensitivity; TSM = Taste/smell sensitivity; MOV = Movement sensitivity; USS = Underresponsive/seeks sensation; AFL = Auditory filtering; LEW = Low energy/weak; VAS = Visual/auditory sensitivity; TMV = Tactile and movement sensitivity; SSD = Sensory seeking/distractibility; HYP = Hypo-responsivity; AVS = Auditory and visual sensitivity
