|Description:||The QIDS is a brief, 16-item self-rated assessment tool used to evaluate the symptoms of depression present in a patient during the past week.|
|Disease States:||Bipolar disorder, Major depressive disorder|
|Validated Uses:||Screening, Diagnosis, Treatment Monitoring & Evaluation, Symptom Severity|
|Populations:||Adolescent, Adult, Geriatric|
|Time to administer:||5–15 minutes|
|Commonly used in:||Clinical Trials & Research, Clinical Practice|
|Detailed Description:||The QIDS is a 16-item, multiple-choice questionnaire in which depressive symptoms are rated on a 0–3 scale according to severity.1,8 Items are derived from the 9 diagnostic criteria for major depressive disorder used in the Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV), including sadness, loss of interest or pleasure, poor concentration or decision-making, self-outlook, suicidal ideation, lack of energy, sleep disturbance, appetite change, and psychomotor agitation.1 The total score ranges from 0–27 and is obtained by adding the scores for each of the 9 symptom domains.1,7
Note: Although the QIDS was initially developed based on DSM-IV criteria, the scale is also compatible with the DSM-5. The core criteria for MDD are consistent across these editions11.
|Scale Validity:||The QIDS demonstrated 79% sensitivity and 81% specificity in a validation study conducted in 596 adult outpatients with dysthymia living in the United States.1|
|Alternative Versions:||The 16-item QIDS scale was derived from a longer, 30-item Inventory of Depressive Symptomatology (IDS), originally published in 1986 and updated in 1996.1,7 The more comprehensive IDS not only assesses the core diagnostic criteria for major depressive disorder listed in the DSM-IV, but also commonly associated symptoms (e.g., anxiety, irritability) and atypical features (e.g., leaden paralysis, interpersonal rejection sensitivity).1,7 Please note that the shortened QIDS is contained entirely within the IDS and thus can be extracted if the longer tool is administered.1 The 16-item QIDS is also available in a clinician-rated format.1 Items are identical across the two formats.7†|
|Cited Limitations:||No limitations have been identified in the literature.|
†Although the 16-item QIDS is described here, we include information about alternative versions for your general awareness and convenience. These alternative versions are sometimes used by different practitioners or in clinical trial or research settings.
