IPASE - Psychotic-Like Anomalous Self-Experiences

Used in psychology/psychiatry to capture subtle manifestations of psychosis-like experiences that do not meet the full diagnostic criteria for a psychotic disorder.

Submeasures include.

• Self-disorders: disturbances in the sense of self, including disruptions in self-awareness, self-boundaries, and self-other differentiation.
• Cognitive disturbances: cognitive anomalies such as thought interference, disorganized thinking, and difficulties in attention and concentration.
• Perceptual anomalies: perceptual disturbances such as hallucinations, illusions, and alterations in the perception of time or space.
• Thought abnormalities:  unusual or idiosyncratic beliefs, magical thinking, and experiences of thought control or insertion.

Limitations:

• self-report measures are subject to biases and inaccuracies.
• Not a dx tool.

Limitations wrt use in autism population

• While there may be autism features that appear to overlap with psychosis (eg: social communication deficits & RRB) they are not indicative of true psychosis.
