Abstract

The aim of the present study was to examine construct validity and reliability of the German reactive proactive aggression questionnaire (RPQ) in a sample of delinquent boys (N = 156). A confirmatory factor analysis with a two-factor model of reactive and proactive aggression showed a good fit to the data. The factor structure of the original RPQ could be fully replicated in the German translation, and Cronbach’s alphas were good for both subscales. Concurrent validity of the RPQ was demonstrated by significant correlations with the subscales of the inventory of callous unemotional traits. In future studies, the German RPQ can be used to assess reactive and proactive aggression in judicial and forensic psychiatric care in Germany. The present findings also provide support for the use of the RPQ in cross-cultural comparisons.
