| dc.description.abstract | The current categorical classification system for personality disorders (PDs) has various limitations and therefore the Alternative DSM-5 Model for Personality Disorders (AMPD) in Section III emerged. The Personality Inventory for DSM-5 (PID-5) is a self-report questionnaire to map the maladaptive personality traits of this model. The instrument has been researched in different countries, but the Dutch translation of the PID-5 has not been studied yet. This was the goal of the current study. The study was conducted in a combined Dutch sample of two Dutch mental health institutions (N = 750). The reliability, convergent validity and factor structure of the PID-5 was studied. The results showed a good reliability at the domain level (range = .89-.93) and reasonable reliability at the trait-level (range = .75-.92). With regards to the validity of the PID-5, the traits of the PID-5 overall correlated with instruments that measure other aspects of personality dysfunctioning (severity) and the six PDs in the DSM-5 Section III (although mostly small to moderate correlations). Some assigned traits did not correlate with specific PDs (i.e., the traits Intimacy avoidance and Restricted affectivity and Obsessive-compulsive PD (OCPD)) and some non-assigned traits had high correlations with specific PDs (e.g., the trait Manipulativeness and Narcisstic PD (NPD)), suggesting rearrangement in trait profiles for PDs. The study found evidence for a five-factor model (Negative affectivity, Detachment, Antagonism, Disinhibition and Psychoticism), although some traits seemed better suited at domains they were not originally assigned to. Further studies should look into additional measures of reliability and validity, employment of cut-off scores, inclusion of validity scales and research in a normal population. To conclude, it can be stated that the Dutch translation of the PID-5 has reasonable to good reliability, validity and factor structure. | |
