Predictive and concurrent validity of parent concern about young children at risk for autism

Area of Science:

• Developmental Psychology
• Autism Spectrum Disorder (ASD) Research
• Pediatric Health

Background:

• Early identification of developmental differences in siblings of children with autism is crucial.
• Parental concerns offer valuable insights into potential developmental trajectories.
• Understanding the predictive value of parental concerns versus clinical assessments is key.

Purpose of the Study:

• To prospectively examine parental concerns regarding child development in siblings of children with autism.
• To compare the predictive accuracy of parental concerns versus standardized tests for ASD outcomes.
• To identify specific developmental domains where parental concerns are most informative.

Main Methods:

• Longitudinal prospective study of 89 younger siblings of children diagnosed with autism.
• Data collected at 14, 24, and 36 months of age.
• Parental concerns and standardized developmental assessments were utilized.

Main Results:

• High rates of parental concern (40-75%) were reported across all ages.
• Parental concerns were significantly higher at 24 and 36 months for children with ASD outcomes.
• Communication concerns were the most frequently reported parental concern.
• Parental communication concern predicted ASD outcomes at 24 and 36 months, but standardized tests showed greater predictive value overall.
• Parental concern demonstrated better specificity than sensitivity for impairment classification.

Conclusions:

• Parental concerns, particularly regarding communication, are valuable indicators in monitoring high-risk siblings.
• Close monitoring of siblings of children with autism is warranted due to persistent developmental concerns.
• Standardized developmental assessments remain the primary tool for predicting ASD outcomes.
