The IDRlabs Depression Spectrum Test (IDR-DST) was developed by IDRlabs. The IDR-DST is based on the work of Dr. Aaron T. Beck, M.D. and his colleagues, who created the Beck Depression Inventory (BDI). The IDR-DST is not associated with any specific researchers in the field of psychopathology or any affiliated research institutions.

The IDRlabs Depression Spectrum Test was informed by the BDI’s criteria for depression, as published in Beck, A.T., Ward, C.H., Mendelson, M., Mock, J., & Erbaugh, J. (1961). An inventory for measuring depression. Archives of General Psychiatry, 4(6), 561. Beck, A.T., Steer, R.A., & Brown, G.K. (1996). Manual for the Beck Depression Inventory-II.

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

The Depression Spectrum Test is based on a famous and well-regarded inventory for the assessment of the clinical concept of depression.
