Anomalous self-experiences are disturbances in the subjective experience of the self and have been shown to be related to the premorbid, prodromal, acute, and chronic phases of schizophrenia-spectrum disorders. Despite having a long history in psychopathology research, anomalous self-experiences are not explicitly represented in any major nosology of mental disorders. Previous research suggests that anomalous self-experiences are correlated, but distinct from other aspects of schizotypal personality, but this has not been examined with confirmatory factor analysis. The current research aimed to examine where anomalous self-experiences fit within the structure of schizotypal personality including cognitive-perceptual, interpersonal, disorganized, and paranoid factors. It also examined the measurement invariance of the factor structure across ethnicity and between sexes. Seven hundred forty-four participants completed multiple measures of anomalous self-experiences and schizotypal personality. The best fitting model was a five-factor model with anomalous self-experiences, cognitive-perceptual, interpersonal, disorganized, and paranoid factors. This model fit better than models with anomalous self-experiences loading on any of the four schizotypal personality factors. The structure had configural, metric, and scalar invariance across race/ethnicities, but lacked scalar invariance between sexes. Anomalous self-experience scores did not differ among race/ethnicity or between sexes. These results suggest that anomalous self-experiences are highly correlated with but distinct from other facets of schizotypal personality. Future research may examine whether anomalous self-experiences should be added to nosologies of psychotic-spectrum disorders.

在非临床样本中将异常的自我体验置于分裂型人格中

异常的自我体验是对自我主观体验的干扰，已被证明与精神分裂症谱系障碍的病前、前驱、急性和慢性阶段有关。尽管在精神病理学研究方面有着悠久的历史，但在任何主要的精神障碍疾病分类学中都没有明确表示异常的自我体验。先前的研究表明，异常的自我体验是相关的，但与分裂型人格的其他方面不同，但这尚未通过验证性因素分析进行​​检验。目前的研究旨在检查异常的自我体验在分裂型人格结构中的位置，包括认知感知、人际关系、混乱和偏执因素。它还检查了跨种族和性别之间因素结构的测量不变性。744 名参与者完成了对异常自我体验和分裂型人格的多项测量。最佳拟合模型是具有异常自我体验、认知感知、人际关系、混乱和偏执因素的五因素模型。该模型比在四个分裂型人格因素中的任何一个上加载异常自我体验的模型更适合。该结构具有跨种族/民族的配置、度量和标量不变性，但缺乏性别之间的标量不变性。异常的自我体验分数在种族/民族或性别之间没有差异。这些结果表明，异常的自我体验与分裂型人格的其他方面高度相关但又截然不同。未来的研究可能会检查异常的自我体验是否应该添加到精神病谱系障碍的疾病分类中。
