The CES-D scale is a brief self-report scale designed to measure self-reported symptoms associated with depression experienced in the past week, specifically developed for older populations. It is not recommended for screening of clinical depression or major depression.
The CES-D is a 10-items questionnaire composed of six scales reflecting major facets of depression: depressed mood, feelings of guilt and worthlessness, feelings of helplessness and hopelessness, psychomotor retardation, loss of appetite, and sleep disturbance.
