Dimensional models of obsessive-compulsive (OC) symptoms, as seen in obsessive-compulsive disorder (OCD), are instrumental in explaining the heterogeneity observed in this condition and for informing cutting-edge assessments. Prior structural work in this area finds that OC symptoms cross-load under both Negative Affectivity and Psychoticism traits within the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) Alternative Model of Personality Disorder (AMPD). However, tests of OC symptoms in conjunction with assessments of the full AMPD structure and its 25 lower-level facets representing narrower symptom content are lacking. We applied joint exploratory factor analysis to an AMPD measure (Personality Inventory for DSM-5; PID-5) and OC symptom data from two separate samples (total N = 1,506) to locate OC symptoms within AMPD space. OC symptoms cross-loaded on Negative Affectivity, Psychoticism, and on the low end of Disinhibition. We also report exploratory analyses of OC symptom subscales with PID-5 variables. Results are discussed in the context OC symptoms’ location in PID-5 space, implications for assessment, and placement of OCD within the Hierarchical Taxonomy of Psychopathology.

强迫症 (OC) 症状的维度模型，如在强迫症 (OCD) 中所见，有助于解释在这种情况下观察到的异质性，并为前沿评估提供信息。该领域先前的结构性工作发现，在《精神障碍诊断和统计手册》（第 5 版；DSM-5）人格障碍替代模型 (AMPD)中，OC 症状在消极情感和精神病特征下交叉负荷。然而，缺乏对 OC 症状的测试以及对完整 AMPD 结构及其代表较窄症状内容的 25 个较低级别方面的评估。我们将联合探索性因素分析应用于 AMPD 测量（DSM-5人格问卷; PID-5) 和来自两个单独样本（总N = 1,506）的 OC 症状数据，用于在 AMPD 空间内定位 OC 症状。OC 症状在负面情感、精神病和去抑制的低端交叉加载。我们还报告了使用 PID-5 变量对 OC 症状量表进行的探索性分析。结果在 OC 症状在 PID-5 空间中的位置、对评估的影响以及强迫症在精神病理学分级分类法中的位置的上下文中进行了讨论。
