Gender differences among children with ADHD on continuous performance tests: a meta-analytic review

Area of Science:

• Neuroscience
• Child Psychology
• Psychiatry

Background:

• Attention-Deficit/Hyperactivity Disorder (ADHD) is a prevalent neurodevelopmental disorder.
• Gender differences in ADHD presentation and diagnosis remain incompletely understood.
• The Continuous Performance Test (CPT) is a key tool for assessing ADHD core symptoms: inattention and impulsivity.

Purpose of the Study:

• To compare the performance on the CPT between boys and girls diagnosed with ADHD.
• To investigate gender-specific differences in impulsivity and inattention among children with ADHD.
• To analyze how gender moderates ADHD symptom expression as measured by CPT.

Main Methods:

• A meta-analysis was conducted on peer-reviewed studies published between 1980 and 2010.
• Studies included were those utilizing a CPT and allowing for gender comparison.
• Analysis focused on gender differences in commission (impulsivity) and omission (inattention) errors.

Main Results:

• The meta-analysis included 772 boys and 325 girls with ADHD.
• Boys with ADHD exhibited significantly higher impulsivity (commission errors) than girls.
• No significant gender difference was observed in inattention (omission errors).
• The diagnostic difference between ADHD and non-ADHD groups was more pronounced in boys than in girls.

Conclusions:

• Gender is a significant moderating factor in evaluating core ADHD symptoms via CPT.
• CPT performance suggests distinct patterns of impulsivity and inattention between genders in ADHD.
• These findings highlight the importance of considering gender in ADHD assessment and interpretation.
