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.
精神病理学层级分类联盟旨在开发一种全面的自我报告量表，以维度的方式评估精神病理学。本研究描述了思维障碍谱系及其他谱系相关结构的初始概念化、发展和项目选择。思维障碍谱系主要由精神分裂症谱系障碍的阳性和紊乱特征和症状定义。思维障碍子工作组确定并定义了 16 个相关结构，并为每个结构编写了 10 到 15 个项目。这些项目与分离和躁狂项目一起，对本科生和严重精神疾病患者进行了测试。在 25 个量表上共进行了 365 个项目的测试。对两个样本的量表得分进行探索性因素分析，结果提示了一个对应正性和负性症状的两因素结构。躁狂量表与正性因子负荷，而分离量表与负性因子负荷。项目水平分析产生了 19 个初步量表，包括涵盖思维障碍病理范围的 215 个项目，这些项目将继续进行下一阶段的数据收集/分析。
