The Alternative DSM-5 Model of Personality Disorders describes the level of personality functioning, defined by impairments in self functioning (self pathology) and problems in interpersonal functioning (interpersonal pathology), as the core feature of all personality disorders. A brief self-report measure to assess the level of personality functioning, the Level of Personality Functioning Scale-Brief Form 2.0 (LPFS-BF) comprising 12 items, was developed by a Dutch work group. The present study aimed at a first and comprehensive psychometric evaluation of the German version of the LPFS-BF in a large and representative general population sample (n=2470) as well as a non-clinical sample (n=849), particularly focusing on the factor structure, convergent validity and norm values. Confirmatory factor analyses revealed that the theoretically assumed and for the original version empirically confirmed two-factor solution was replicated in both samples with acceptable fit. Reliability of the total scale as well as both subscales (defined by the internal consistency) was high in both samples (McDonalds ω ≥0.83). Satisfactory convergent validity was indicated by high correlations of the German version of the LPFS-BF with other measures assessing personality dysfunction (r ≥0.72). The association with current psychological distress was similarly high. In the general population sample, the mean norm value (T) of the total scale was 15 and T was 33. Although psychometric evaluations of the German LPFS-BF in patients with mental disorders, particularly those with personality disorders, have not yet been performed, this measure can be recommended as it provides a quick and user-friendly impression of the severity of personality functioning in the domains of self and interpersonal pathology.
《精神疾病诊断与统计手册》第五版人格障碍替代模型将人格功能水平描述为所有人格障碍的核心特征，人格功能水平由自我功能损害（自我病理）和人际功能问题（人际病理）来定义。一个荷兰工作组编制了一份简短的自我报告量表，即人格功能水平量表简版2.0（LPFS - BF），用于评估人格功能水平，该量表包含12个项目。本研究旨在对LPFS - BF德文版在一个大型且具有代表性的普通人群样本（n = 2470）以及一个非临床样本（n = 849）中进行首次全面的心理测量学评估，特别关注其因子结构、收敛效度和常模值。验证性因子分析表明，在两个样本中都复制了理论上假设且在原版中经实证证实的两因子解决方案，拟合度可接受。两个样本中总量表以及两个子量表的信度（由内部一致性定义）都很高（麦克唐纳ω≥0.83）。LPFS - BF德文版与其他评估人格功能障碍的量表高度相关（r≥0.72），表明具有令人满意的收敛效度。与当前心理困扰的关联同样很高。在普通人群样本中，总量表的平均常模值（T）为15，[此处原文似乎不完整，可能遗漏了关于另一个T值的完整表述]。尽管尚未对精神障碍患者，尤其是人格障碍患者进行LPFS - BF德文版的心理测量学评估，但由于该量表能快速且方便地呈现自我和人际病理领域人格功能障碍的严重程度，因此可以推荐使用。
