The DAPP-BQ in The Netherlands: factor structure and relationship with basic personality dimensions.
After discarding eight items in the Dutch translation of Livesley's DAPP-BQ that showed item-total correlations < 0.20 in a sample of 223 normal subjects. Cronbach's alpha coefficients were calculated for the remaining items in the 18 scales of this instrument. The 'Dutch' alpha coefficients proved to be satisfactory. Furthermore, the Dutch DAPP-BQ scales were factor analyzed, retaining four factors. Three of these factors proved to be identical (Emotional Dysregulation and Dissocial) or nearly identical (Compulsivity) to the Canadian factors. However, the original factor Inhibition was not the same as the remaining Dutch factor Intimacy Problems. In a sample of 115 students, the estimated scores for the Dutch Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ) factors were correlated with the scales of Van Kampen's Four-Dimensional Personality Test. As expected, Emotional Dysregulation was found to correlate with Neuroticism, Dissocial with Insensitivity, and Compulsivity with Orderliness. The Intimacy Problems factor proved to be negatively correlated with Extraversion. The results obtained are embedded in the context of the evidence favoring a dimensional model of personality disorder. Furthermore, Livesley's proposal that separate diagnostic criteria for the existence of a personality disorder must be formulated to supplement the assessment by means of the DAPP-BQ is critically discussed.
