More About the Center for Epidemiologic Studies Depression Scale (CESD)

The CESD is a questionnaire developed in the 1970s to detect major or clinical depression. The questions are easy to answer and cover most of the areas included in the diagnostic criteria for depression. The questionnaire has been completed by thousands of individuals in primary care offices and from their homes. Almost 85% of those found to have depression after an in-depth structured interview with a psychiatrist will have a high score on the CESD. However, about 20% of those who score high on the CESD will have rapid resolution of their symptoms and not meet full criteria for major or clinical depression. Therefore, it is necessary to see your doctor for an accurate diagnosis.
