Repetitive Motor Behaviors in Non-Autistic Toddlers.

ABSTRACT:

Objective

To evaluate repetitive motor behaviors (RMBs) in non-autistic toddlers using direct observational methods.

Study design

This cohort study assessed RMBs in a community sample of 679 toddlers at 24 and 36 months of age. Initial analyses examined rates of RMBs in autistic (n = 65) vs nonautistic (n = 614) participants. Subsequent analyses focused on participants without autism, first examining clinical correlates of RMBs in the full non-autistic group and then comparing rates of RMBs in 2 non-autistic subgroups: 104 participants with other developmental concerns (ODC) and 510 participants with no developmental concerns.

Results

A total of 36% of non-autistic children demonstrated RMB at 24 and/or 36 months of age. RMBs were significantly more likely in the ODC
