RT Article T1 A meta-analysis on cognitive distortions and externalizing problem behavior: associations, moderators, and treatment effectiveness JF Criminal justice and behavior VO 42 IS 3 SP 245 OP 262 A1 Helmond, Petra A2 Overbeek, Geertjan A2 Brugman, Daniel A2 Gibbs, John C. LA English YR 2015 UL https://krimdok.uni-tuebingen.de/Record/1885233248 AB Cognitive distortions are an important focus in many investigations and treatments of externalizing problem behavior, such as antisocial, delinquent, and aggressive behavior. Yet the overall strength of the association between cognitive distortions and externalizing behavior is unknown. Furthermore, it is unknown whether interventions can effectively reduce cognitive distortions and subsequently externalizing behavior. To fill these gaps, we conducted a meta-analysis of 71 studies on 20,685 participants. Results showed a medium to large effect size (d = .70) for the association between cognitive distortions and externalizing behavior. Interventions had a small effect (d = .27) on reducing cognitive distortions. In a subset of intervention studies that incorporated both cognitive distortions and externalizing behavior, however, neither cognitive distortions nor externalizing behavior were effectively reduced. Hence, although cognitive distortions are substantially linked to externalizing behavior and interventions can reduce cognitive distortions, a subsequent reduction in externalizing behavior remains to be demonstrated.
