Girls with autism spectrum disorder (ASD) show relative strengths in social communication but weaker socialization skills compared to other adaptive behaviors. Differences in repetitive behaviors may be parent-reported rather than observed.
Area of Science:
- Neurodevelopmental Disorders
- Child Psychology
- Behavioral Science
Background:
- Autism Spectrum Disorder (ASD) presents unique challenges in social communication and behavior.
- Understanding sex-specific differences in ASD presentation is crucial for accurate diagnosis and intervention.
- Girls with ASD often exhibit distinct social and behavioral patterns compared to boys.
Purpose of the Study:
- To compare social communication, repetitive behaviors, and adaptive functioning in girls with ASD versus typically developing (TD) girls.
- To investigate specific differences in social interaction, communication, and repetitive behaviors using standardized measures.
- To identify potential areas of relative strength and weakness in adaptive behavior for girls with ASD.
Main Methods:
- A cohort of 37 girls (18 ASD, 19 TD), aged 7-15, matched for age and IQ.
- Utilized Social Communication Questionnaire (SCQ), Autism Diagnostic Observation Schedule (ADOS-2), and Vineland Adaptive Behavior Scales (VABS-2).
- Analyzed item-level scores for social interaction, communication, and repetitive behaviors, alongside overall adaptive behavior scores.
Main Results:
- Significant differences between ASD and TD girls were found on numerous SCQ and ADOS-2 items, particularly after statistical adjustment.
- A negative correlation was observed within the ASD group between repetitive behaviors and communication scores.
- Girls with ASD demonstrated borderline to moderately low scores on VABS-2, indicating challenges in adaptive functioning.
Conclusions:
- Girls with ASD may exhibit relative strengths in social communication as assessed by diagnostic tools.
- Parent-reported behaviors might capture differences in repetitive behaviors not evident in structured observations.
- Socialization skills appear to be a relative weakness in girls with ASD, suggesting a priority for targeted interventions.
