Psychosis Spectrum Test
The psychosis spectrum encompasses a range of psychotic symptoms, all pointing to the presence of disorders such as Delusional Disorder, Schizotypal Personality Disorder, Schizophrenia, and Schizoaffective Disorder. However, there is considerable variation in the type and severity of the symptoms.
This test combines the insights of several prior efforts to research psychosis spectrum symptoms to bring you a single, composite test measuring psychotic occurrences across 10 different domains.

The IDRlabs Psychosis Spectrum Test (IDR-PST) was developed by IDRlabs. The IDR-PST is based on the work of Dr. Susan Rossell and her colleagues, who created the Questionnaire for Psychotic Experiences (QPE). The IDR-PST is not associated with any specific researchers in the field of psychopathology or any affiliated research institutions.
The IDRlabs Psychosis Spectrum Test was informed by the QPE’s criteria for psychosis as published in Rossell, S.L., Schutte, M., Toh, W., Thomas, N., Strauss, C., Linszen, M., Dellen, E., Heringa, S., Teunisse, R., Slotema, C., & Sommer, I. (2019). The questionnaire for psychotic experiences: An examination of the validity and reliability. Schizophrenia Bulletin, 45 (1), pp.78-87; Schutte, M., et al. (2020).

The work of Dr. Rossell and her colleagues has also informed some of the diagnostic criteria in the form of the widely used psychological instrument, the QPE, for clinical use especially by qualified mental health professionals. The present test is intended for educational purposes only. IDRlabs and the present IDRlabs Psychosis Spectrum Test are independent of the above researchers, organizations, or their affiliated institutions.
