Il modello alternativo dei disturbi di personalitá nel DSM-5 e le sue implicazioni per la perizia in ambito canonico

The present paper is aimed at illustrating the alternative model of personality disorders (PD), included in the DSM-5 system, with a series of possible implications for the expert report in the canon law field. In order to do this, the DSMIV TR diagnostic system with its limits as well as the new criterions of DSM-5 alternative model of PD were systematically presented and articulated. In particular, a series of new proposals, included in the alternative model, were illustrated and critically evaluated, clarifying their role for the improvement of DSM-IV TR unresolved questions, such as the excessive comorbidity of PD categories, the high heterogeneity of individuals with the same PD diagnosis, the obsolete approach to diagnostic thresholds, the temporal instability of diagnoses, the narrow range of personality psychopathology considered and the lack of a theoretical model, empirically founded, that is able to support the criterions. Improvements that DSM-5 alternative model may involve for the expert report in the canon law field, especially regarding the link between diagnostic label and legal incapacity, are discussed.
