Note. Table reports means, followed by SDs and ranges in parentheses. Scores above 2 on the RRB Diagnostic Algorithm Total score meet the ASD cutoff on the ADI. For significant findings on individual ADI items, percentages of participants who exhibited mildly repetitive behavior (no impairment in functioning, received “1” on the ADI item) or moderate to severe repetitive behavior (received a 2 or 3 on the ADI item) are reported.
