The placement of anomalous self-experiences within schizotypal personality in a nonclinical sample
Abstract
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…

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
