The CDI is self-rated, which means that the child or adolescent being assessed to records their answers to the questions on the test sheet. Each question on the CDI consists of three possible responses. The CDI is designed to make quantitative measurements of the following symptoms of depression: mood disturbances; capacity for enjoyment; depressed self-evaluation; disturbances in behavior toward other people; and vegetative symptoms, which include fatigue, oversleeping, having difficulty with activities requiring effort, and other symptoms of passivity or inactivity.
|Scoring||The test administrator totals the responses and plots them onto a profile|
|Reliability and Validity||
Across one group of nine studies, alpha measures were 0.71-0.89, reflecting good internal consistency. Studies in addition to those completed by Kovacs have shown moderate to high reliability. The validity of the CDI has been well-established. Kovacs used experimental design to obtain discriminant validity between cases that were considered “normal” and those that were considered clinical.
Based on a nationally representative sample of 1,100 children and teens from 26 U.S. states, with equal numbers of males and females at each age.
The Children’s Depression Inventory can be used by clinicians and counselors to assess self-reported key symptoms of depression, Support diagnosis and treatment planning and for conducting clinical research.
