The IDRlabs Borderline Personality Disorder Spectrum Test (IDR-BPDST) was developed by IDRlabs. The IDR-BPDST is based on the work of Dr. Mary Zanarini and her colleagues, who created the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD). The IDR-BPDST is not associated with any specific researchers in the field of psychopathology or any affiliated research institutions.

The IDRlabs Borderline Personality Disorder Spectrum Test was informed by the MSI-BPD’s criteria for borderline personality disorder, as published in Zanarini, Mary & Vujanovic, A & Parachini, Elizabeth & Villatte, Jennifer & Frankenburg, Frances & Hennen, John. (2003). A screening measure for BPD: The McLean screening instrument for Borderline Personality Disorder (MSI-BPD). Journal of personality disorders. 17. 568-73. 10.1521/pedi.17.6.568.25355.
