Edinburgh Postnatal Depression Scale

The Edinburgh Postnatal Depression Scale (EPDS) is a 10-item self-report questionnaire developed in 1987 by Dr. John Cox, Dr. Jeni Holden, and Dr. Ruth Sagovsky at health centers in Livingston and Edinburgh, Scotland. It was specifically designed to screen for postnatal depression by excluding somatic symptoms (such as fatigue, appetite changes, and sleep disturbance) that are normal experiences in the postpartum period and would inflate scores on general depression scales like the Beck Depression Inventory or the PHQ-9. This deliberate design choice makes the EPDS uniquely suited for perinatal populations. The EPDS assesses mood, anxiety, and self-harm ideation over the past 7 days. Each of the 10 items is scored from 0 to 3, yielding a total score range of 0 to 30. Items 1, 2, and 4 are reverse-scored (the response indicating the least distress receives 3 rather than 0). A score of 13 or higher is the most widely used cutoff for probable major depression, while a score of 10 to 12 suggests possible depression warranting clinical follow-up. Item 10, which asks about self-harm thoughts, requires immediate clinical assessment regardless of the total score. Postnatal depression affects approximately 10 to 15 percent of women in high-income countries and up to 20 to 25 percent in low and middle income countries. Without screening, approximately 50 percent of postnatal depression cases go undetected in clinical practice. The EPDS has been validated in over 60 languages and across diverse cultural populations. At a cutoff of 13, it demonstrates sensitivity of approximately 86 percent and specificity of approximately 78 percent for major depressive disorder. Although originally developed for postnatal use, the EPDS has been validated for antenatal (prenatal) depression screening and is increasingly used throughout pregnancy. Research also supports its use in screening for perinatal anxiety, with items 3, 4, and 5 forming a three-item anxiety subscale. Some clinical guidelines now recommend the EPDS for screening fathers and non-birthing partners in the perinatal period as well, recognizing that paternal postnatal depression affects approximately 8 to 10 percent of fathers.

1. 1Identify Appropriate Timing for Screening: The EPDS should be administered at multiple time points during the perinatal period. The American College of Obstetricians and Gynecologists recommends screening at least once during the perinatal period using a standardized validated tool. Many guidelines recommend screening at the first prenatal visit, during the third trimester, at the 6-week postpartum visit, and at the 3-month and 6-month well-baby visits. Postnatal depression can develop at any point during the first year postpartum, so a single negative screen does not rule out later onset. Some clinicians also screen during the second trimester when antenatal depression risk increases.
2. 2Prepare the Patient and Setting: Administer the EPDS in a private, comfortable setting. Explain that the questionnaire asks about feelings over the past 7 days and that it is given to all perinatal patients as a routine part of care. Normalize the experience by stating that mood changes are common during pregnancy and after birth and that screening helps identify individuals who might benefit from additional support. The EPDS can be self-administered on paper, electronically (tablet or smartphone), or read aloud by the clinician for patients with low literacy. Ensure the questionnaire is available in the patient's preferred language.
3. 3Score Each Item with Attention to Reverse Scoring: Each item has four response options scored from 0 to 3. For items 1, 2, and 4, the responses are ordered so that the option indicating the most positive mood receives 0 points. For example, item 1 ('I have been able to laugh and see the funny side of things') is scored: 'As much as I always could' = 0, 'Not quite so much now' = 1, 'Definitely not so much now' = 2, 'Not at all' = 3. Items 3 and 5 through 10 are scored with the response indicating the most distress receiving 3 points. This scoring ensures that higher total scores always indicate greater distress.
4. 4Assess Item 10 Independently for Safety: Item 10 states 'The thought of harming myself has occurred to me' with responses: 'Never' (0), 'Hardly ever' (1), 'Sometimes' (2), or 'Yes, quite often' (3). Any response other than 'Never' requires immediate clinical follow-up regardless of the total EPDS score. When a patient endorses self-harm thoughts, the clinician should conduct a thorough suicide risk assessment, ask about the nature and frequency of these thoughts, whether there is intent or a plan, access to means, and protective factors. Depending on the assessment, immediate psychiatric referral, safety planning, or emergency intervention may be required.
5. 5Calculate and Interpret the Total Score: Sum all 10 items for the total EPDS score (range 0-30). Interpret using established cutoffs: 0-9 indicates depression is unlikely, 10-12 indicates possible depression warranting monitoring and possible clinical follow-up, and 13 or higher indicates probable depression requiring comprehensive clinical assessment. Some guidelines use a lower cutoff of 10 for minor depression and 13 for major depression. For antenatal screening, some researchers recommend a higher cutoff of 15 due to slightly different psychometric properties during pregnancy. Also calculate the anxiety subscale (items 3, 4, 5) to assess the anxiety component.
6. 6Consider Cultural and Individual Context: Interpret the EPDS score within the patient's cultural and individual context. Cultural norms around emotional expression, stigma associated with mental health concerns, expectations of motherhood, and social support structures all influence how patients respond to the EPDS. Some cultures discourage the expression of negative emotions, potentially leading to underreporting. Others may normalize significant distress as an expected part of motherhood. Additionally, consider situational factors such as infant health problems (NICU admission, colic), relationship difficulties, financial stress, and social isolation that may contribute to elevated scores without necessarily indicating clinical depression.
7. 7Develop an Appropriate Care Plan: Based on the EPDS score and clinical assessment, develop an individualized care plan. For scores of 10-12, options include increased monitoring with repeat screening in 2 to 4 weeks, psychoeducation about perinatal mood disorders, referral to peer support groups, and lifestyle interventions (exercise, sleep hygiene, social support). For scores of 13 or higher, options include referral for clinical interview to confirm diagnosis, psychotherapy (cognitive behavioral therapy or interpersonal therapy are first-line), pharmacotherapy if indicated (sertraline and paroxetine are commonly used SSRIs compatible with breastfeeding), and in severe cases, referral to a perinatal psychiatrist. Always discuss the impact of untreated maternal depression on infant development and attachment.

• !Stosowanie ogólnych skal depresji zamiast EPDS w okresie okołoporodowym: Skala Depresji PHQ-9 i Inwentarz Depresji Becka obejmują objawy somatyczne, takie jak zmęczenie, zmiany apetytu, zaburzenia snu i obniżona energia. Objawy te są niemal powszechne w okresie poporodowym i niekoniecznie wskazują na depresję. Stosowanie ogólnych skal depresji w okresie okołoporodowym zawyża wyniki i skutkuje niedopuszczalnie wysokim odsetkiem wyników fałszywie dodatnich. Skalę EPDS opracowano specjalnie w celu wykluczenia objawów somatycznych, koncentrując się zamiast tego na emocjonalnych i poznawczych objawach depresji. Chociaż PHQ-9 może być stosowany w okresie okołoporodowym ze świadomością tego ograniczenia, EPDS pozostaje złotym standardowym narzędziem przesiewowym w populacjach okołoporodowych.
• !Badanie przesiewowe wyłącznie podczas wizyty poporodowej w 6 tygodniu: Wiele systemów opieki zdrowotnej przeprowadza badanie w kierunku depresji poporodowej jedynie podczas wizyty w 6 tygodniu po porodzie. W podejściu tym pomija się depresję przedporodową (która dotyka około 12 procent kobiet w ciąży), wczesną depresję poporodową, która może wystąpić przed 6 tygodniem ciąży, oraz depresję poporodową o późnym początku, która rozwija się po wstępnym badaniu przesiewowym. Najlepsza praktyka obejmuje badanie przesiewowe przynajmniej raz w czasie ciąży (najlepiej podczas pierwszej wizyty prenatalnej i ponownie w trzecim trymestrze ciąży), podczas wizyty w 6 tygodniu po porodzie oraz podczas kolejnych wizyt u zdrowego dziecka przez co najmniej 6 miesięcy po porodzie. Niektóre wytyczne wydłużają badania przesiewowe przez pierwszy rok po porodzie.
• !Odrzucanie podwyższonych wyników jako normalnego stresu u nowych rodziców: Utrzymującym się błędem klinicznym jest przypisywanie podwyższonych wyników EPDS oczekiwanemu stresowi i brakowi snu w związku z nowym rodzicielstwem, zamiast rozpoznawać klinicznie istotną depresję lub stany lękowe. Chociaż przystosowanie się do rodzicielstwa jest trudne, EPDS został specjalnie zaprojektowany w celu rozróżnienia normalnych poporodowych wahań emocjonalnych od klinicznie istotnych zaburzeń nastroju. Wynik EPDS wynoszący 13 lub więcej nie powinien być nigdy lekceważony jako „po prostu stres nowego rodzica”. Każdy podwyższony wynik wymaga obserwacji klinicznej, nawet jeśli klinicysta podejrzewa, że ​​wynik odzwierciedla stres sytuacyjny, a nie depresję, ponieważ stres sytuacyjny, który osiąga znaczenie kliniczne, wymaga interwencji niezależnie od jego postrzeganej przyczyny.
