The DSM-5 presents an Alternative Model for Personality Disorder (AMPD) recommending the assessment of impairments in core personality functions as well as clinically relevant personality traits. Although a self-report assessment instrument has been provided corresponding to the trait model proposed in the AMPD, no comparable instrument provides a direct assessment of the specific indicators of core personality functions described in that model. The goal of this paper is to provide preliminary reliability and validity data for a measure that directly corresponds to core personality pathology as operationalized in the AMPD. Self-report questions were generated to capture each diagnostic indicator provided in the Level of Personality Functioning Scale, a clinician rating guide provided in the AMPD that describes characteristic impairments in identity, self-direction, empathy, and intimacy at 5 different levels of personality functioning. These questions were administered to a community sample of 306 participants, with the resulting scale examined for internal consistency, unidimensionality, and concurrent validity with 4 other self-report measures of global personality dysfunction. Items representing the 4 subcomponents of personality dysfunction were found to manifest high degrees of internal consistency, and were highly related to each other, supporting the AMPD contention that these core dysfunctions reflect a single dimension of personality dysfunction. Correlations with concurrent validity measures were large, with associations at the global level of dysfunction often exceeding .80. The developed instrument is reprinted in the supplementary materials, with the goal of encouraging additional refinement and development by other investigators as part of the call for additional research on the AMPD.

DSM-5 提出了一种人格障碍的替代模型（AMPD），建议评估核心人格功能的损伤以及临床上相关的人格特征。尽管已经提供了与 AMPD 中提出的特质模型相对应的自评评估工具，但没有可比的工具可以直接评估该模型中描述的核心人格功能的特定指标。本文的目的是提供一种与 AMPD 中操作化的核心人格病理直接对应的测量方法的初步信度和效度数据。生成了自评问题来捕捉在人格功能水平量表中提供的每个诊断指标，这是 AMPD 中提供的临床医生评分指南，描述了在 5 种不同人格功能水平上的身份、自我导向、同理心和亲密关系的特征损伤。这些问题被管理到一个 306 名参与者的社区样本中，对由此产生的量表进行了内部一致性、单维性以及与其他 4 种全球人格功能障碍自评测量的同时效度的检验。代表人格功能障碍 4 个亚成分的项目表现出高度的内部一致性，并且彼此高度相关，这支持了 AMPD 的论点，即这些核心功能障碍反映了人格功能障碍的单一维度。与同时效度测量的相关性很大，在功能障碍的全球水平上的关联通常超过.80。在补充材料中重新刊登了开发的工具，目的是鼓励其他研究人员进行更多的细化和发展，作为对 AMPD 进行更多研究的呼吁的一部分。
