Tratti disfunzionali di personalità nel paziente tossicodipendente detenuto. Somministrazione del PID-5 ad un campione clinico

Abstract Including a dimensional rather than categorical classification of disorders, section III of the DSM-5 presents a new model for the assessment of personality disorders. Consistently with such model, the APA has generated a paradigm for the assessment of dysfunctional personality traits, the Personality Inventory for DSM-5 (PID-5) consisting of 25 personality facets identified in 5 domains (Krueger et al., 2012). The present research findings have been obtained by administering the PID-5 to a sample of 101 patients under the care of an addiction recovery service within a penitentiary in Lombardy. Results are first presented as mean scores for each trait and compared with the normative data of the Italian adaptation of the instrument in order to provide professionals working in the field with clinically relevant information. Following, results of a confirmatory factor analysis (CFA) aimed at testing the structure proposed by Krueger et al. (2012) on a clinical sample are also presented. Findings confirm the presence of 5 domains, however some differences with regards to the overall number of facets (15 instead of 25) composing each domain have to be acknowledged. More specifically, some maladaptive sub-dimensions (i.e. manipulativeness, separation insecurity, hostility, deceitfulness, callousness, etc.) did not univocally converge on one domain and have therefore been eliminated from the model. Although preliminary, this study provides grounds for reflection on the connections between personality disorders, drug addiction, and crime and shows how the adoption of a multi-faceted perspective might contribute to the development of more focused and effective interventions.
