Quick Inventory of Depressive Symptomatology Clinician-Rated Version Clinical Classification

**Semantic type:** Intellectual Product

**Definition:** A standardized 16-item clinician-scored questionnaire, derived from the 30-item Inventory of Depressive Symptomatology (IDS), that utilizes a 5-point rating scale for the assessment of the severity of depressive symptoms over the seven day period prior to evaluation. The original questionnaire, created by Rush et al. in 1986, includes the nine diagnostic DSM-IV symptom domains that are used to characterize a major depressive episode, as well as items to address melancholic and atypical features. The shortened, 16-item version was initially developed by Rush et al. in 2000 by selecting only items from the original scale that assessed DSM-IV criterion diagnostic symptoms.
