NEUROPSYCHOLOGICAL MEASURES OF EXECUTIVE FUNCTION AND ANTISOCIAL BEHAVIOR: A META-ANALYSIS*

Abstract

A meta-analysis was performed to quantify the association between antisocial behavior (ASB) and performance on neuropsychological executive functioning (EF) measures. This meta-analysis built on Morgan and Lilienfeld's (2000) meta-analysis of the same topic by including recently published studies and by examining a wider range of EF measures. A total of 126 studies involving 14,786 participants were included in the analyses. Antisocial groups performed significantly worse on measures of EF compared with controls, with a grand mean effect size of d= .44. Significant variation occurred in the magnitude of effect sizes calculated across studies. The largest effect sizes were found for criminality (d= .61) and externalizing behavior disorder (d= .54) ASB groups, whereas the smallest effect sizes were found for antisocial personality disorder (d= .19) groups. Larger differences in EF performance were observed across studies involving participants from correctional settings and with comorbid attention deficit and hyperactivity problems. Overall, the results indicated that a robust association exists between ASB and poor EF that held across studies with varied methodological approaches. The methodological issues in the research literature and the implications of the meta-analysis results are discussed, and the directions for future research are proposed.
