Parent reported preschool attention deficit hyperactivity: measurement and validity.

Area of Science:

• Child Psychology
• Developmental Psychiatry
• Behavioral Science

Background:

• Hyperactivity and behavior problems are common in preschool children.
• Understanding the distinct and overlapping impacts of these conditions is crucial for early intervention.
• Existing scales may not fully capture the spectrum of these issues in young children.

Purpose of the Study:

• To develop and validate an Attention Deficit Hyperactivity Scale (ADH-P) for preschool children.
• To examine the characteristics and correlates of children with pure hyperactivity, pure behavior problems, and a mixed group.
• To compare the severity of psychopathology and external correlates across these groups.

Main Methods:

• A two-stage community study involving 320 preschool children (ages 2.5-5 years).
• Development and validation of the ADH-P scale using parent reports, teacher reports, and clinical observations.
• Classification of children into four groups: pure hyperactive, pure behavior problem, mixed, and no problem, based on parent reports.

Main Results:

• The ADH-P scale demonstrated satisfactory reliability and validity.
• Children in the mixed group (hyperactivity and behavior problems) exhibited more symptoms.
• The mixed group also showed poorer maternal mental health, higher social adversities, and increased help-seeking behavior compared to other groups.

Conclusions:

• Co-occurring hyperactivity and behavior problems in preschool children lead to significantly worse outcomes.
• The developed ADH-P scale is a reliable and valid tool for assessing hyperactivity in this age group.
• Early identification and intervention for children with combined hyperactivity and behavior problems are essential to mitigate negative impacts.
