Construct Validity of the German Version of the Hare Psychopathy Checklist – Revised
Abstract
psychopathy. The PCL-R is a 20-item observer rating instrument based on file review and a semi-structured interview. The current study aimed
to investigate the validity of the German adaptation of the PCL-R, its factor structure, construct validity, and association with socially desirable
responding in a sample of male offenders (N = 118). A parcel model with four facets and two factors yielded excellent model fit. Convergent
and discriminant validity were assessed based on correlational analyses, a multitrait-multimethod (MTMM) matrix, and a canonical correlation
analysis (CCA) including measures of psychopathy, antisocial personality disorder (ASPD), global personality dimensions, alexithymia, and
impulsivity. The MTMM matrix as well as substantial associations with self-reported psychopathic traits and observer ratings of ASPD indicated convergent validity. Correlational analyses revealed that Factor 1 of the PCL-R was associated with low neuroticism, whereas Factor
2 was associated with impulsivity as well as with low agreeableness and conscientiousness. The PCL-R total score and Factor 2 were
negatively correlated with impression management. Overall, the current findings support the validity of the German adaptation of the PCL-R.
