The Hierarchical Taxonomy of Psychopathology consortium aims to develop a comprehensive self-report measure to assess psychopathology dimensionally. The current research describes the initial conceptualization, development, and item selection for the thought disorder spectrum and related constructs from other spectra. The thought disorder spectrum is defined primarily by the positive and disorganized traits and symptoms of schizophrenia-spectrum disorders. The Thought Disorder Sub-Workgroup identified and defined 16 relevant constructs and wrote 10 to 15 items per each construct. These items were administered, along with detachment and mania items, to undergraduates and people with serious mental illness. Three hundred and sixty-five items across 25 scales were administered. An exploratory factor analysis of the scale scores suggested a two-factor structure corresponding to positive and negative symptoms for two samples. The mania scales loaded with the positive factor, while the detachment scales loaded with the negative factor. Item-level analyses resulted in 19 preliminary scales, including 215 items that cover the range of thought disorder pathology, and will be carried forward for the next phase of data collection/analysis.

精神病理学层次分类法思维障碍测量的发展

The Hierarchical Taxonomy of Psychopathology 联盟旨在开发一种全面的自我报告措施,以从维度上评估精神病理学。目前的研究描述了思维障碍谱和其他谱的相关结构的初始概念化、发展和项目选择。思维障碍谱主要由精神分裂症谱系障碍的积极和混乱的特征和症状来定义。思维障碍子工作组确定并定义了 16 个相关结构,并为每个结构编写 10 到 15 个项目。这些项目连同超然和躁狂项目一起被提供给本科生和患有严重精神疾病的人。管理了 25 个量表的 365 个项目。量表分数的探索性因素分析表明,两个样本的阳性和阴性症状对应的双因素结构。狂热量表加载了积极因素,而分离量表加载了负面因素。项目级分析得出19个初步量表,包括涵盖思维障碍病理学范围的215个项目,将用于下一阶段的数据收集/分析。
