WHAT THE TEST MEASURES

About This Assessment

Children's Depression Inventory (CDI) Test

depression

This measure is used to screen for depressive symptoms and related affective concerns in children and adolescents. The Children's Depression Inventory (CDI) is commonly administered in outpatient, school, and research settings to support initial problem identification and symptom monitoring.

It is a self-report questionnaire consisting of 27 items and typically takes about 5 minutes to complete. Item content samples multiple domains often associated with depression (e.g., mood, anhedonia, self-evaluation, somatic complaints), allowing clinicians to quantify symptom burden and track change over time. The Children's Depression Inventory (CDI) was developed by Maria Kovacs and is intended to inform, not replace, a comprehensive clinical assessment and diagnostic evaluation.
