Abstract

This report supports validation for the Spanish 18-item short version of the Inventory of Personality Organization (IPO), a self-reported instrument for the assessment of personality organization, according to Kernberg’s object-relation based model. The IPO is used to depict personality structure types, using three scales: psychological defense mechanisms, degree of identity integration and reality testing. The review of the literature suggests alternatively factorial solutions. Accordingly, this study, using a nonclinical sample (N = 315), tested the fit of several factorial models (2- and 3- factor solution) via the maximum likelihood approach. Confirmatory Factor Analysis revealed a better fit for the 2-factor solution (CFI = .97, TLI = .96, RMSEA = .037, AIC = 311.06), in accordance with Kernberg’s theory. Each of the 2 IPO subscales shows good levels of internal consistency, and they are associated with increased negative affect, aggressive dyscontrol as well as depression, anxiety and general level of psychopathological distress in line with theoretical expectations. Our results suggest that the Spanish short version of the IPO is a reliable and valid tool for the assessment of personality organization following Kernberg’s model.

摘要

根据克恩伯格基于对象关系的模型，该报告支持对西班牙18个项目的个性化组织清单（IPO）进行简短验证，这是一种自我报告的评估个性化组织的工具。首次公开募股使用三种尺度来描述人格结构类型：心理防御机制，身份整合程度和现实测试。文献综述提出了阶乘解。因此，本研究使用非临床样本（N = 315），通过最大似然法测试了多个阶乘模型（2和3因子解）的拟合度。验证性因子分析表明，根据Kernberg的理论，两因子解决方案更适合（CFI = .97，TLI = .96，RMSEA = .037，AIC = 311.06）。2个IPO分量表中的每个分量表均显示出良好的内部一致性，并且与负面影响增加，攻击性失控以及抑郁，焦虑和心理病理困扰的总体水平均与理论预期相符。我们的结果表明，西班牙短版IPO是遵循Kernberg模型评估人格结构的可靠有效工具。
