Abstract

The Alternative DSM-5 Model for Personality Disorders (AMPD) consists of level of personality functioning (Criterion A) and maladaptive personality traits (Criterion B). The brief scale versions of these are understudied, while often being used by clinicians and researchers. In this study, we wanted to investigate the overlap and predictive validity of Criterion A and B. Participants (N = 253) were measured on level of personality functioning (LPFS-BF) and maladaptive personality traits (PID-5-BF), as well as internalizing outcomes such existential meaninglessness (EMS) and externalizing outcomes such as substance and behavioral addictions (SSAB). Data analysis was conducted with principal component analysis (PCA) and regression analyses. The results showed over 50% overlap between the brief versions of Criterion A and B, while Criterion B slightly outperformed Criterion A in outcomes of EMS and SSAB. We discuss the potential redundancy and usefulness of personality functioning and maladaptive personality traits.

摘要

人格障碍替代 DSM-5 模型 (AMPD) 由人格功能水平（标准 A）和适应不良人格特质（标准 B）组成。这些的简短比例版本尚未得到充分研究，但经常被临床医生和研究人员使用。在本研究中，我们想要调查标准 A 和 B 的重叠和预测有效性。参与者 ( N = 253）测量人格功能水平（LPFS-BF）和适应不良人格特质（PID-5-BF），以及内化结果（如存在无意义（EMS））和外化结果（如物质和行为成瘾（SSAB）） 。数据分析采用主成分分析（PCA）和回归分析。结果显示，标准 A 和 B 的简要版本之间有超过 50% 的重叠，而标准 B 在 EMS 和 SSAB 的结果方面略优于标准 A。我们讨论人格功能和适应不良人格特质的潜在冗余和有用性。
