Question 1

What is the CES-D?

Accepted Answer

The CES-D (Center for Epidemiologic Studies Depression Scale) is a 20-item self-report depression screening tool developed by Lenore Radloff at the National Institute of Mental Health (NIMH) in 1977. It was originally designed for epidemiological research to measure depressive symptoms in the general population. It covers depressed mood, feelings of guilt and worthlessness, helplessness, psychomotor retardation, loss of appetite, and sleep disturbance. It is one of the most widely cited depression instruments in the world.

Question 2

How is the CES-D scored?

Accepted Answer

Each of the 20 items is rated on a 4-point scale for the past week: 0 (Rarely or none of the time, less than 1 day), 1 (Some or a little of the time, 1-2 days), 2 (Occasionally or a moderate amount of the time, 3-4 days), 3 (Most or all of the time, 5-7 days). Four items (#4, #8, #12, #16) are positively worded and reverse-scored: for these, the scoring is reversed (0 becomes 3, 1 becomes 2, etc.). The total score ranges from 0 to 60. A score of 16 or higher is a traditional follow-up threshold, not a diagnosis or severity rating.

Question 3

What are the reverse-scored items?

Accepted Answer

Items 4 ("I felt that I was just as good as other people"), 8 ("I felt hopeful about the future"), 12 ("I was happy"), and 16 ("I enjoyed life") are positively worded. For these items, answering "Most or all of the time" scores 0 (indicating good wellbeing), while "Rarely" scores 3 (indicating poor wellbeing). This reverse scoring prevents response bias (where someone might select the same answer for every item without reading) and allows the scale to measure both negative symptoms and the absence of positive affect.

Question 4

What is the difference between the CES-D and the PHQ-9?

Accepted Answer

Both screen for depression, but they differ in scope and clinical use. The CES-D has 20 items and covers a broader range of experiences including interpersonal difficulties and positive affect. The PHQ-9 has 9 items directly aligned with DSM-5 diagnostic criteria for major depressive disorder. The PHQ-9 is more commonly used in clinical settings today because of its brevity and diagnostic alignment. The CES-D remains widely used in research, community health screening, and studies involving diverse populations. Both are free and public domain.

Question 5

What does a CES-D score of 16 or higher mean?

Accepted Answer

A score of 16 or higher on the CES-D is a traditionally used threshold for identifying people who may benefit from follow-up. It does not diagnose depression or assign a severity level. Many factors can affect a score, including grief, stress, medical illness, and sleep disruption. A qualified healthcare professional can help interpret symptoms in context.
