OBJECTIVE: As repetitive behaviours in children with autism spectrum disorders (ASDs) can significantly interfere with one's daily functioning, continued research on these behaviours is needed. METHODS: This study examined the occurrence of repetitive motor movements in toddlers (17-37 months) with ASD and atypical development and the relationship between stereotypies and sensory impairment. RESULTS: Children with ASD (n = 13) exhibited significantly more repetitive behaviours than the non-ASD group (n = 12). Greater percentages of endorsement were evident for the ASD group on nearly all items of the Behaviour Problems Inventory-01 (BPI-01) Stereotypy subscale. More repetitive behaviours tended to co-occur with other stereotypies for the ASD group. A moderate correlation was found between stereotypy severity and sensory deficits. CONCLUSION: These findings suggest that stereotyped behaviours can be identified at very young ages, negatively affect the behavioural presentation of those with ASDs and should be considered when developing treatment plans.
