Comparison of the Structured DSM-5 Clinical Interview for the Level of Personality Functioning Scale With the Structured Interview of Personality Organization.

In Section III of DSM-5, the Level of Personality Functioning Scale (LPFS), a component of the DSM-5 Alternative Model for Personality Disorders (AMPD), offers a dimensional approach to the assessment of personality pathology. Similar to the psychoanalytic concept of personality organization developed by Kernberg ( 1984 ), personality disorders are assessed not only by categorical diagnoses, but also by measuring impairment of personality functioning. In this study we empirically investigate the convergence between two instruments examining personality functioning, the Structured Clinical Interview for the DSM-5 Alternative Model for Personality Disorders Module I (SCID-AMPD) and the Structured Interview of Personality Organization (STIPO).
