EPDS Score Interpretation — Cutoff Reference

Total EPDS scores range from 0 to 30. There is no single universally agreed cutoff; clinicians use the ranges below as a guide alongside clinical assessment.

Total ScoreCategoryInterpretationSuggested Action
0–8Low ProbabilityDepressive illness unlikelyRoutine care; repeat screening at next scheduled visit
9–12PossiblePossible depressive symptoms — borderlineClinical interview recommended; consider repeat EPDS in 2 weeks
13+ProbableProbable depressive illness of varying severityFull clinical assessment; consider referral to mental health services
Item 10 >0Safety FlagAny thoughts of self-harm reportedImmediate further enquiry — regardless of total score
💡 The original 1987 validation study used a cutoff of ≥10 (sensitivity 85%, specificity 77%). Many services now use ≥13 as the threshold most strongly suggestive of a depressive illness. Always follow your local protocol.

EPDS — Clinical Reference Guide

What is the Edinburgh Postnatal Depression Scale?

The Edinburgh Postnatal Depression Scale (EPDS) is a validated 10-item self-report questionnaire, first developed in 1987 by Cox, Holden, and Sagovsky at health centres in Edinburgh and Livingston, Scotland. It was designed to screen for depressive symptoms during pregnancy and the postpartum period. Unlike general depression screening tools such as the PHQ-9, the EPDS focuses on emotional and cognitive symptoms rather than physical symptoms — since features like fatigue and sleep disturbance are common in normal pregnancy and the postpartum period and would otherwise inflate scores.

How EPDS Scoring Works

Each of the 10 items is scored from 0 to 3, giving a total score range of 0 to 30. Items 1, 2, and 4 are scored in the standard direction (0, 1, 2, 3 from the top response to the bottom). Items 3 and 5 through 10 are reverse scored (3, 2, 1, 0). Higher total scores indicate more depressive symptoms. The questionnaire takes approximately 5 minutes to complete and asks the woman to describe how she has felt over the past 7 days, not just on the day of testing.

When to Use the EPDS

The EPDS can be administered at any point during pregnancy and is most commonly used between 6 and 8 weeks postpartum, though many services also screen at the booking visit, in the third trimester, and at routine postnatal follow-ups. Because mood can change over time, the EPDS may need to be repeated on further occasions as clinically warranted — a single low score does not rule out depression developing later.

Frequently Asked Questions

What is the Edinburgh Postnatal Depression Scale (EPDS)?

The EPDS is a validated 10-item self-report questionnaire developed in 1987 to screen for depressive symptoms during pregnancy and the postpartum period. Each item is scored 0 to 3, giving a total score from 0 to 30. It is a screening tool, not a diagnostic instrument, and a raised score should always be followed by clinical assessment.

What is the EPDS cutoff score for postnatal depression?

The original validation study suggested a cutoff of 10, with 85% sensitivity and 77% specificity. A score of 10 or more suggests possible depressive illness and warrants further assessment. A score of 13 or more is more strongly suggestive of a depressive illness of varying severity. Any score above zero on item 10 requires immediate further enquiry regardless of the total score.

How is the EPDS scored?

Each of the 10 EPDS items is scored 0 to 3. Items 1, 2, and 4 are scored in the order the responses are listed. Items 3 and 5 through 10 are reverse scored. The total score is the sum of all 10 item scores, ranging from 0 to 30. Higher scores indicate more depressive symptoms.

Can the EPDS be used during pregnancy, not just after birth?

Yes. Although originally developed for the postnatal period, the EPDS has been validated for use during pregnancy as well, and is commonly used for antenatal depression screening in addition to postpartum screening.

Is the EPDS a diagnostic tool?

No. The EPDS is a screening tool only, not a diagnostic instrument. A score above the cutoff indicates a need for further clinical assessment to confirm or exclude a depressive illness. The EPDS score should never override clinical judgement.

What does a positive response to EPDS item 10 mean?

Item 10 asks about thoughts of self-harm. Any response other than "never" on this item requires immediate further enquiry to assess the nature and level of risk, regardless of the total EPDS score, with appropriate safeguarding and referral for both mother and baby.
