The Alternative DSM-5 Model for Personality Disorders and the latest eleventh version of the International Classification of Diseases implement the level of impairment in self and interpersonal personality functioning (Level of Personality Functioning Scale - LPFS) as a core feature of personality pathology. However, some studies have indicated that personality functioning is also impaired in other mental disorders, but a more thorough exploration is missing. Thus, this study aims to develop profiles of levels of personality functioning in people with personality disorders and some other psychiatric diagnoses as well as without diagnosis.
One-hundred-forty-nine people participated in the study. They came from three groups - healthy controls (n = 53), people with personality disorders (n = 58), and people with mood and anxiety disorders (n = 38). The LPFS was assessed by the Semi-structured Interview for Personality Functioning DSM-5 (STiP-5.1). An optimal clustering solution using agglomerative hierarchical cluster analysis was generated to represent profiles of personality functioning.
The two patient groups showed significantly higher levels of personality functioning impairment than healthy controls. People with personality disorders showed higher levels of impairment than the other groups. In addition, the clustering analysis revealed three distinct profiles of personality functioning.
The impairment of personality functioning seems to be useful in the clinical assessment of other than personality disorders as well. As the resulting clustering profiles suggest, LPFS can be seen as an overall indicator of the severity of mental health difficulties and the presence of mental disorders symptoms. The LPFS provides valuable and detailed information about the individual's mental health and can thus serve as a broad basis for case formulation, treatment and therapy planning, and prognosis.
替代 DSM-5 人格障碍模式和最新的第十一版国际疾病分类将自我和人际人格功能障碍的损害程度（人格功能水平量表 - LPFS）作为人格病理学的核心特征。然而，一些研究表明，人格功能也在其他精神障碍中受损，但缺乏更深入的探索。因此，本研究旨在开发人格障碍患者以及其他一些精神诊断和无诊断患者的人格功能水平特征。
共有 149 人参与了这项研究。他们来自三个组 - 健康对照组（n = 53）、人格障碍组（n = 58）和心境和焦虑障碍组（n = 38）。使用 DSM-5 人格功能半结构化访谈（STiP-5.1）评估 LPFS。使用凝聚层次聚类分析生成最佳聚类解决方案来代表人格功能特征。
两个患者组的人格功能损害水平明显高于健康对照组。人格障碍组的损害程度高于其他组。此外，聚类分析显示了三种不同的人格功能特征。
人格功能障碍的损害似乎对人格障碍以外的临床评估也有用。如聚类分析结果所示，LPFS 可以作为心理健康困难严重程度和精神障碍症状存在的整体指标。LPFS 提供了有关个体心理健康的有价值和详细信息，因此可以作为案例制定、治疗和治疗计划以及预后的广泛基础。
