DSM-5 with "DSM-5 Alternative Model for Personality Disorder Model" provides a new hybrid approach to the diagnostics of personality disorder, both dimensional and categorical, and proposes a model for conceptualization of personality disorders in which they are characterized by impairment of personality functioning and pathological personality traits. Personality inventory for DSM-5 (PID-5) is a self-report measure designed to assess the presence and severity of maladaptive personality traits. The long form of PID-5 consists of 220 self-assessment items used to measure 25 maladaptive personality facets, which are included in five broad domains of higher order. The adaptation and validation of the Romanian version of PID-5 for the Romanian population in the Republic of Moldova was carried out on a sample of 225 participants. The results have provided evidence that the Romanian version of PID-5 can be used to assess reliably and validly the maladaptive personality traits described in the alternative model of the DSM-5.
