The Center for Epidemiologic Studies Depression Scale (CES-D) is a widely used questionnaire for screening assessment of depressive symptoms in the general population. It consists of 20 questions and is designed to evaluate the frequency of symptoms during the past week.
Unlike many other tests, the CES-D can identify not only pronounced but also subclinical depressive manifestations. The questionnaire includes items assessing positive affect (reverse-scored questions), allowing evaluation not only of negative symptoms but also of reduced positive emotions. The scale is widely used in epidemiological and clinical research.
