Attention deficit-hyperactivity disorder among mentally retarded children

Area of Science:

• Child Psychology
• Neurodevelopmental Disorders
• Educational Psychology

Background:

• Attention Deficit-Hyperactivity Disorder (AD-HD) is a common neurodevelopmental disorder.
• Intellectual disability can co-occur with AD-HD, potentially influencing symptom presentation and behavioral patterns.
• Accurate assessment of AD-HD symptoms in children with intellectual disabilities is crucial for effective intervention.

Purpose of the Study:

• To compare the teacher-rated behavioral symptoms of AD-HD in children with normal intelligence versus those with intellectual disabilities.
• To investigate differences in AD-HD symptom profiles between groups with varying IQ levels and AD-HD severity.

Main Methods:

• Teachers rated 100 boys using the Connors' Teacher Rating Scale (CTRS-39).
• Participants were categorized into four groups: normal IQ AD-HD, intellectually disabled, intellectually disabled with AD-HD, and a normal control group.
• Group assignments were based on IQ screening and DSM-III-R AD-HD symptom checklist scores.

Main Results:

• No significant differences were found between the normal IQ AD-HD group and the intellectually disabled AD-HD group on most CTRS-39 factors.
• Intellectually disabled children, as a general group, were rated as significantly more anxious than their normal peers.
• Children with normal IQ and AD-HD were rated higher on the 'Asocial' factor compared to other groups.

Conclusions:

• AD-HD symptom presentation on teacher rating scales may be similar between children with normal intelligence and those with intellectual disabilities.
• Anxiety appears to be a more prominent feature in intellectually disabled children overall.
• The distinct 'Asocial' factor rating in normal IQ AD-HD children warrants further investigation into social behavior differences.
