Utility of the Japanese version of the Checklist for Autism in Toddlers for predicting pervasive developmental disorders at age 2.
We evaluated the utility of the Japanese version of the Checklist for Autism in Toddlers for predicting pervasive developmental disorders (PDD) among 2-year-old children in clinical settings. Confirmed diagnosis revealed that the pass rate on four items (social interest, proto-imperative pointing, proto-declarative pointing and joint-attention) was significantly lower in 52 PDD children than in 48 non-PDD children, and if abnormal development was reported in two or more items, the sensitivity, specificity, and positive/negative predictive values for PDD diagnosis were 0.85, 0.73, and 0.77/0.81, respectively. This simple screening tool can provide valuable information to clinicians when diagnosing PDD.
