The DSM-5 Section III alternative model of personality disorder (AMPD) and the International Classification of Diseases – 11th Edition's (ICD-11) personality disorder classification allow clinicians to identify individual trait domains in which people score highly. However, how these domains relate to constructs associated with efficacious treatment approaches is unclear. The current study aimed to determine whether constructs from two evidence-based treatments (schema therapy [ST] and dialectical behavior therapy [DBT]) were associated with maladaptive personality traits in a way consistent with underlying theories. We examined associations between ST constructs, DBT skill use and maladaptive coping styles, and personality traits in a sample of 525 adults. Bivariate intercorrelations and a series of multiple regression analyses were conducted to investigate the associations. As hypothesized, maladaptive coping was strongly associated with all trait domains. Surprisingly, poor DBT-skill use was only associated with negative affectivity, detachment, and disinhibition trait domains. Specific schema domains were associated with each personality trait domain, supporting trait domain-schema domain specificity. The current study highlights the potential clinical utility of the AMPD and ICD-11 trait models and ultimately contributes to the dearth of evidence on their likely usefulness for treatment selection, planning, and applications.

将 DSM-5 和 ICD-11 特征域与图式治疗和辩证行为治疗结构联系起来

DSM-5 第 III 节人格障碍替代模型 (AMPD) 和国际疾病分类 – 第 11 版 (ICD-11) 人格障碍分类使临床医生能够识别人们得分较高的个体特质领域。然而，这些领域如何与有效治疗方法相关的结构相关尚不清楚。当前的研究旨在确定两种循证治疗（图式疗法[ST]和辩证行为疗法[DBT]）的构建是否与适应不良的人格特质相关，其方式与基本理论一致。我们以 525 名成年人为样本，研究了 ST 结构、DBT 技能使用和适应不良的应对方式以及人格特质之间的关联。进行双变量互相关和一系列多元回归分析来研究相关性。正如假设的那样，适应不良的应对方式与所有特质领域都密切相关。令人惊讶的是，DBT 技能使用不当仅与负面情感、疏离和去抑制特征领域相关。特定的模式域与每个人格特质域相关联，支持特质域-模式域的特异性。目前的研究强调了 AMPD 和 ICD-11 特征模型的潜在临床效用，并最终导致缺乏证据证明它们对治疗选择、规划和应用可能有用。
