Early Indicators of Autism in Infants: Development of the IMES Screening Tool.

Scientists created a new screening test called IMES to spot early signs of autism in babies aged 6-9 months by watching how they play and interact. They tested it on videos of 15 baby boys, including 7 who were later diagnosed with autism. Early results look promising, but more research is needed before this tool can be used widely to help identify autism earlier than current methods.

Researchers developed the Infant, Motor, and Engagement Scale (IMES), a new screening tool designed to identify autism spectrum disorder in infants as young as 6-9 months. The IMES assesses how infants interact with people and objects during play. The study examined 15 male infants (7 later diagnosed with autism) using retrospective home videos. Preliminary findings suggest the IMES demonstrates acceptable reliability between raters, internal consistency, and content validity according to expert review.

This represents an important step toward earlier autism identification, as current diagnostic tools typically identify children much later. The researchers emphasize that further research is needed to establish the tool's effectiveness before clinical implementation.

The IMES represents a promising tool for earlier autism screening in infancy, potentially enabling intervention during critical developmental windows. However, extensive validation research is required before clinical adoption to establish sensitivity, specificity, and broader applicability across diverse populations.

Very small sample size (15 infants, 7 with autism), male-only participants, retrospective video analysis rather than prospective screening, preliminary data only. Larger validation studies needed before clinical implementation.

We developed the Infant, Motor, and Engagement Scale (IMES) to address the public health goal of early identification of autism spectrum disorder (ASD). The IMES is a screening tool that assesses quality of infants' interaction with people and objects during early play. We aimed to examine the IMES' preliminary psychometric properties and its value in discriminating between infants later diagnosed with ASD and typically developing infants. We used the IMES to score retrospective home videos of 15 male infants, 7 who were later diagnosed with autism.

We examined interrater reliability using Cohen's Kappa, internal consistency with Cronbach's alpha and content validity through expert review. Preliminary data support validity and reliability of the IMES for early identification for infants at 6 to 9 months. With further research, the IMES has the potential to identify at risk infants at a young age that may have long-term impact on child and family outcomes.
