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 Kernberg 的基于对象关系的模型，该报告支持对西班牙语 18 项简短版本的人格组织清单 (IPO) 进行验证，这是一种用于评估人格组织的自我报告工具。IPO用于刻画人格结构类型，使用三个尺度：心理防御机制、身份整合程度和现实测试。对文献的回顾提出了备选的阶乘解决方案。因此，本研究使用非临床样本（N = 315)，通过最大似然方法测试了几个因子模型（2 和 3 因子解决方案）的拟合。根据 Kernberg 的理论，验证性因子分析显示更适合 2 因子解决方案（CFI = .97，TLI = .96，RMSEA = .037，AIC = 311.06）。2 个 IPO 分量表中的每一个都显示出良好的内部一致性水平，并且它们与增加的负面影响、攻击性控制障碍以及抑郁、焦虑和符合理论预期的一般心理病理困扰水平相关。我们的结果表明，西班牙文的 IPO 简短版本是一种可靠且有效的工具，可用于按照 Kernberg 模型评估人格组织。
