Abstract or Description

The aim was to build a profile of motor development in infant siblings of children diagnosed with autism. Infants at high familial risk of developing autism spectrum disorder and those at low-risk were tested longitudinally between 6 and 24 months. Data were analysed from the gross and fine motor scales of the Mullen Scales of Early Learning and the Vineland Adaptive Behavior Scales at three age points. Low-risk and at-risk infants differed significantly on motor scales at all three visits, with significantly lower motor scores in the at-risk group evident from the age of 6 months based on parental report. Poorer gross and fine motor skills in the at-risk group were only evident on the direct standardised assessment from 12 months. Only gross motor scores were highly correlated across the two measures. A combination of standardised assessments and parental reports may therefore provide the best method for early identification of motor atypicalities in the broader autism phenotype.
