The Level of Personality Functioning - Brief Form 2.0 (LPFS-BF 2.0) is a 12-item self-report questionnaire developed to gain a quick impression of the severity of personality pathology according to the DSM-5 Alternative Model for Personality Disorders (AMPD). The current study evaluated the construct validity and reliability of the Norwegian version of the LPFS-BF 2.0 in a large clinical sample (N = 1673). Dimensionality was examined using confirmatory factor analysis and bifactor analysis followed by an analysis of distinctiveness of the subscales using the proportional reduction in mean squared error (PRMSE), and the concurrent validity was examined using correlations with self-report questionnaires and clinical interviews assessing PDs according to section II of the DSM-5. Taking the findings of the dimensionality and concurrent validity results together, we found moderate to good support for the use of total scores for the Norwegian version of the LPFS-BF 2.0. We would advise against the use of subscale scores, since the subscales provided only a small amount of reliable unique variance.
人格功能水平 - 简短形式 2.0（LPFS-BF 2.0）是一个 12 项的自我报告问卷，旨在根据 DSM-5 人格障碍替代模型（AMPD）快速获得人格病理学严重程度的印象。本研究在一个大型临床样本（N=1673）中评估了 LPFS-BF 2.0 的挪威版本的结构效度和信度。使用验证性因子分析和双因素分析检查了维度，然后使用均方误差的比例减少（PRMSE）分析子量表的独特性，并使用与根据 DSM-5 第二部分评估 PD 的自我报告问卷和临床访谈的相关性检查同时效度。综合考虑维度和同时效度的结果，我们发现对于挪威版 LPFS-BF 2.0 的总分的使用有中等至良好的支持。我们建议不要使用子量表得分，因为子量表仅提供了少量可靠的独特方差。
