The Inventory of Psychotic-Like Anomalous Self-Experiences (IPASE) shows strong construct validity as a self-report measure of minimal self-disturbance. In a sample of 46 participants including ultra-high risk and first-episode psychosis patients and healthy controls, the IPASE correlated very strongly (r = 0.92) with the gold-standard interview measure (EASE). It also correlated strongly with general psychopathology and positive psychotic symptoms, moderately with negative symptoms, and weakly with manic symptoms. The IPASE may serve as a screener but cannot replace the in-depth assessment of minimal self-disturbance, which requires clinical expertise.
