Children's Depression Inventory

The Children's Depression Inventory (CDI) is a self-report diagnostic tool used to measure the severity of depression in children between the ages of 7 and 17. The CDI is considered a reliable measure of depression in children and adolescents, with high internal consistency and good test-retest reliability. It consists of 27 items that measure the frequency and intensity of symptoms of depression, such as sadness, hopelessness, thoughts of death, feelings of guilt, and physical problems. The CDI is an important tool for assessment and diagnosis of depression in children and adolescents in clinical settings, as well as for research purposes, and for tracking and managing change over time.
