Social processing (SP) deficits manifest across numerous mental disorders. However, this research has been plagued by heterogeneity and a piecemeal approach whereby skills are examined in isolation rather than as part of an integrated cognitive system. Here, we combined two dimensional frameworks of psychopathology to address these limitations.
We utilized the Alternative Model for Personality Disorders (AMPD) to distill trait-related heterogeneity within a community sample (n = 200), and the Research Domain Criteria (RDoC) 'Systems for Social Processes' to comprehensively assess SP. We first applied latent class analyses (LCA) to derive AMPD-based groups and subsequently contrasted the performance of these groups on a SP test battery that we developed to align with the RDoC SP constructs.
Our LCA yielded four distinct subgroups. The recognizable trait profiles and psychopathological symptoms of these classes suggested they were clinically meaningful. The subgroups differed in their SP profiles: one displayed deficits regarding the self, a second displayed deficits in understanding others, a third displayed more severe deficits including affiliation problems, whilst the fourth showed normal performance.
Our results support the link between clusters of maladaptive personality traits and distinctive profiles of SP deficits, which may inform research on disorders involving SP dysfunctions.
社会处理（SP）缺陷在许多精神障碍中表现出来。然而，这项研究受到异质性和零碎方法的困扰，即技能是孤立地检查的，而不是作为一个综合认知系统的一部分。在这里，我们结合了心理病理学的二维框架来解决这些局限性。
我们利用人格障碍替代模型（AMPD）来提炼社区样本（n=200）中的特质相关异质性，并利用研究领域标准（RDoC）的“社会处理系统”来全面评估 SP。我们首先应用潜在类别分析（LCA）来得出基于 AMPD 的组，然后对比这些组在我们开发的与 RDoC SP 结构相匹配的 SP 测试组合上的表现。
我们的 LCA 产生了四个不同的亚组。这些类别的可识别特质特征和精神病理症状表明它们具有临床意义。这些亚组在 SP 特征上存在差异：一个表现出自我缺陷，第二个表现出理解他人的缺陷，第三个表现出更严重的缺陷，包括隶属问题，而第四个表现出正常表现。
我们的结果支持适应不良的人格特质集群与 SP 缺陷的独特特征之间的联系，这可能为涉及 SP 功能障碍的障碍研究提供信息。
