The Association Between Autism Symptoms and Child Functioning in a Sample With ADHD Recruited From the Community

Area of Science:

• Child and Adolescent Psychiatry
• Developmental Psychology
• Neurodevelopmental Disorders

Background:

• Autism spectrum disorder (ASD) symptoms are frequently observed in children with attention-deficit/hyperactivity disorder (ADHD).
• These co-occurring symptoms are associated with diminished functional outcomes in children with ADHD.
• However, the specific ASD symptom domains that contribute most significantly to functional impairment remain unclear.

Purpose of the Study:

• To investigate the association between specific autism spectrum disorder (ASD) symptom domains and the functional outcomes of children diagnosed with attention-deficit/hyperactivity disorder (ADHD).
• To identify which ASD symptom domains are most impairing for children with ADHD.

Main Methods:

• A cohort of 164 children with ADHD participated in the study.
• Parents completed diagnostic interviews for ADHD and comorbidities.
• ASD symptoms were assessed using the Social Communication Questionnaire.
• Child quality of life was measured using the Pediatric Quality of Life Inventory 4.0.
• Parents and teachers utilized the Strengths and Difficulties Questionnaire to report on emotional, conduct, and peer problems.

Main Results:

• Repetitive and stereotyped behaviors were significantly associated with increased emotional problems (p = .02) and conduct problems (p = .03).
• These repetitive behaviors also correlated with poorer quality of life (p = .004).
• Deficits in reciprocal social interaction were independently linked to greater peer problems (p = .03).

Conclusions:

• Reciprocal social interaction deficits and repetitive/stereotyped behaviors represent critical areas for attention in the assessment and treatment of children with ADHD.
• Targeting these specific ASD symptom domains may improve functional outcomes for children with ADHD.
