title: Gender differences among children with ADHD on continuous performance tests: a meta-analytic review.
abstract: OBJECTIVE
  Gender differences among children with ADHD are not well understood. The continuous performance test (CPT) is the most frequently used direct measure of inattention and impulsivity. This meta-analysis compared CPT performance between boys and girls with and without ADHD.
  
  
  METHODS
  All peer-reviewed ADHD studies published between 1980 and 2010 that used a CPT and enabled gender comparison were included. Gender differences in commission (impulsivity) and omission (inattention) errors were analyzed.
  
  
  RESULTS
  Included studies comprised a sample of 772 boys and 325 girls with ADHD. Findings show that boys were significantly more impulsive than girls, but no difference with inattention was found. Within-gender analysis revealed that the difference among boys with and without ADHD was significantly larger than the difference among girls with and without ADHD.
  
  
  CONCLUSIONS
  The results indicate that gender is a significant moderating factor in the assessment of core ADHD symptoms when using CPTs.
