aVerbal IQ, Performance IQ and Full Scale IQ were measured using the WASI-II (Wechsler 2011)
bSocial Communication Questionnaire (Rutter et al. 2003). A score of 15 or above indicated elevated levels of autistic symptomology
cADOS = Autism Diagnostic Observation Schedule (Lord et al. 1999, 2012). Scores of 7 or above indicate the presence of an ASD
dSBQ = Sensory Behavior Questionnaire (lower scores reflect greater levels of sensory behaviors)
eSSP = Short Sensory Profile (lower scores reflect greater levels of sensory behaviors)
fSCAS-P = Spence Children’s Anxiety Scale (higher scores reflect greater levels of anxiety)
