Personality disorders (PDs) in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) are conceptualized as distinct clinical syndromes. However, debate persists about the clinical utility of this categorical model, with many researchers supporting a dimensional model that focuses on pathological personality traits and personality dysfunction. This model was published in Section III of DSM-5 and named the Alternative Model of Personality Disorders (AMPD). This study evaluated the AMPD by examining relationships between traits and dysfunction with traditional categorical PD constructs among older adults. Older adults (N = 202) completed the Personality Inventory for DSM-5, Levels of Personality Functioning Scale-Self-Report, and Coolidge Axis II Inventory. Results indicated that pathological personality traits do not relate to categorical PDs in directions predicted by the AMPD. Personality functioning related to categorical PDs in expected theoretical patterns according to the AMPD but lacked incremental validity above pathological personality traits. An implication of these findings is that the AMPD does not fully resolve the age-related issues with the traditional categorical PD model.

精神障碍诊断和统计手册( DSM-5 ) 中的人格障碍 (PD)被概念化为不同的临床综合征。然而，关于这种分类模型的临床实用性的争论仍然存在，许多研究人员支持关注病理性人格特征和人格障碍的维度模型。该模型发表在DSM-5 的第三部分，并命名为人格障碍的替代模型 (AMPD)。本研究通过检查老年人特征与功能障碍与传统分类 PD 结构之间的关系来评估 AMPD。老年人 ( N = 202) 完成了DSM-5的人格量表、人格功能等级-自我报告和柯立芝轴 II 量表。结果表明，病理性人格特征与 AMPD 预测的方向上的分类 PD 无关。根据AMPD，人格功能与预期理论模式中的分类PD相关，但缺乏高于病理性人格特征的增量有效性。这些发现的一个含义是，AMPD 没有完全解决传统分类 PD 模型中与年龄相关的问题。
