Multidimensional Depression Test
Depression is a mental health condition characterized by low mood and loss of interest or pleasure in daily activities that goes beyond episodic sadness or grief. Left untreated, depression can cause significant impairment to well-being and functioning. Depression is one of the most common mental illnesses: Approximately 7% of adults experience at least one major depressive episode in any given year, with numerous studies estimating lifetime prevalence rates of depression to be over 20%.

The IDRlabs Multidimensional Depression Test (IDR-MDT©) was developed by IDRlabs International. The IDR-MDT is based on the American Psychiatric Association’s diagnostic criteria and the Patient Health Questionnaire (PHQ-9) depression screening tool. The IDR-MDT is not associated with any specific researchers in the field of psychopathology, or any affiliated research institutions.
The IDRlabs Multidimensional Depression Test was informed by the American Psychiatric Association’s diagnostic criteria for depression published in the DSM-5, as well as the widely used psychological instrument, the PHQ-9 developed by Spitzer, Williams, Kroenke, and colleagues. The PHQ-9 is a clinical instrument intended for use by qualified professionals and researchers. The present test is intended for educational and entertainment purposes only. IDRlabs International and the present IDRlabs Multidimensional Depression Test are independent from any of the above researchers, organizations, or their affiliated institutions.
The Multidimensional Depression Test is based on a well-known tool for the assessment of the psychological construct of depression. However, free online tests such as this are solely initial considerations of the concept being examined and cannot provide entirely accurate assessments of your personality, character, or any components of your psychological state. This test is to be used for screening purposes only. A definitive mental health diagnosis can be made only by a physician, psychiatrist, or other mental health professional.
As the publishers of this free online depression test, which allows you to screen yourself for the signs and symptoms of this mental health condition that may otherwise remain unrecognized, we have strived to make the test as reliable, valid, and comprehensive as possible, by subjecting this test to statistical controls and validation. Though developed and statistically validated by psychology professionals, free online tests and quizzes such as the present Multidimensional Depression Test do not provide professional assessments or recommendations of any kind; the test results of our free online depression test are provided “as-is.” For more detailed information about the current test or any of our other online psychological tests, please consult our Terms of Service.
