The psychometric properties of the Danish version of the Dimensional Assessment of Personality Pathology-Basic questionnaire (DAPP-BQ) were assessed in both a clinical (N = 76) and a nonclinical sample (N = 168). Internal consistencies of all scales were adequate in both samples. The four factors labeled Emotional Dysregulation (ED), Dissocial behavior (DB), Inhibition (IH), and Compulsivity (CO) were fully replicated in the clinical sample but only partially replicated in the nonclinical sample. Congruency coefficients between samples ranged from .98 to .80. Convergent validity of the DAPP-BQ was tested by correlation analysis with the Structured Clinical Interview for DSM-IV Personality Disorders (SCID-II) and Inventory of Interpersonal Problems-Circumplex (IPP-C) scores. Relationship to the SCID-II was largely as predicted and in accordance with previous research. Correlations between DAPP-BQ higher order dimensions and IPP-C were also largely as hypothesized but also called attention to important conceptual issues including the fact that the higher-order term Emotional Dysregulation may not be an adequate label for a domain of behaviors that are highly interpersonal. Overall, the results indicate a successful translation of the DAPP-BQ and the strong association with interpersonal problems is regarded as an additional support for the content validity of the model.
