The Inventory of Personality Organization–Revised

Construction of an Abridged Version

Published Online:November 05, 2009https://doi.org/10.1027/1015-5759.25.4.223

Abstract

The Inventory of Personality Organization (IPO, Kernberg & Clarkin, 1995; Lenzenweger, Clarkin, Kernberg, & Foelsch, 2001) is a self-report instrument intended to measure a patient’s level of personality organization. This manuscript describes the development of a shortened version of the IPO (the IPO-R). Construct validity of the IPO-R is determined by investigating (a) its latent structure, (b) the equivalence of this latent structure in a normal and a clinical sample (structural validity), and (c) differences between mean scores of the IPO-R scales for a normal population, axis-I disordered and axis-II disordered patients (concurrent validity). The IPO-R showed adequate construct validity in a normal and a clinical sample.
