The IDRlabs Paranoid Personality Spectrum Test (IDR-PPST) was developed by IDRlabs. The IDR-PPST is based on the work of Dr. David Rawlings, Ph.D. and Justin L. Freeman, who created the Paranoia/ Suspiciousness Questionnaire (PSQ). The IDR-PPST is not associated with any specific researchers in the field of psychopathology or any affiliated research institutions.

The IDRlabs Paranoid Personality Spectrum Test was informed by the PSQ’s criteria for paranoia, as published in Rawlings, D. & Freeman, J.
