Depression Self-Assessment

The Patient Health Questionnaire (PHQ-9) is a self-assessment tool for depression. It has nine parts: one for each of the diagnostic criteria for depression, according to the DSM-IV. PHQ-9 results are scored based on the frequency of depressive symptoms, from 0 (“not at all”) to 3 (“nearly every day”). Clinically, the PHQ-9 is used to monitor the severity of a patient’s depression and/or a patient’s response to treatment.  The PHQ-9 is an important tool for tracking the progress of depression symptoms during and after TMS, a highly effective and non-invasive treatment for major depressive disorder.
