In December 2019, the American Academy of Pediatrics (AAP) updated their recommendations for the screening of autism for the first time since 2007. Here is a brief summary of the new guidelines issued by the AAP. · All children should be screened for symptoms of autism spectrum disorder (ASD) at all visits. · Developmental and behavioral screenings should be performed at the 9-month, 18-month, and 30-month visits. · Standardized autism-specific screening tests should be performed at 18 and 24 months of age. One of the primary reasons for the change is that children with ASD can be identified as young as toddlers. As with many conditions, early intervention is crucial and can influence outcomes. PAR is proud to publish an instrument that can help clinicians adhere to these new guidelines. The PDD Behavior Inventory™ Screening Edition (PDDBI-SV) can be used to screen children at risk for autism spectrum disorder as young as 18 months. It can be administered in 10 minutes or less, letting you know quickly if the child is at risk. If further evaluation is warranted, PAR’s PDDBI and the PDDBI ASD Decision Tree can also be used with children as young as 18 months of age.
