Minimal self-disturbance—a fragility in the implicit sense of self, presence, and agency—is a core feature of schizophrenia spectrum disorders. In a test of a neurophenomenological model, source monitoring deficits explained 39.8% of the variance in minimal self-disturbance scores across 50 ultra-high risk patients, 39 first-episode psychosis patients, and 34 healthy controls. Aberrant salience explained only 6% of the variance and was more related to positive psychotic symptoms than to self-disturbance. The model may need to incorporate additional constructs like temporal processing and multisensory integration. Longitudinal analyses will follow.
