Why use it

Postpartum depression affects approximately 10–15% of mothers and up to 10% of fathers, and is severely underdiagnosed. Untreated PPD is associated with impaired mother-infant bonding, adverse infant developmental outcomes, relationship breakdown, and suicide risk. The EPDS is brief, non-stigmatizing, and can be completed in under 5 minutes, making it ideal for routine perinatal care. Major professional bodies including ACOG, AAP, NICE, and WHO recommend routine postnatal depression screening using the EPDS.

About

The Edinburgh Postnatal Depression Scale (EPDS) is the most widely used validated screening tool for postpartum depression (PPD), developed by Cox, Holden, and Sagovsky at the University of Edinburgh. It is a 10-item self-report questionnaire that asks about depressive symptoms experienced in the past 7 days. Each item is scored 0–3, yielding a total score of 0–30. Validated in over 60 countries and translated into more than 60 languages, it has been adapted for use in fathers, partners, and during the antenatal period. Although originally developed for the postnatal period, it is validated for use throughout pregnancy. A score ≥10 indicates possible depression warranting further assessment; a score ≥13 in most studies indicates probable major depression. Question 10 (self-harm ideation) is a mandatory safety screen regardless of total score.

When to use

  • Routine screening at first antenatal visit and at 6–8 weeks postpartum (per NICE guidance)
  • Any antenatal or postnatal appointment when depressive symptoms are suspected
  • Screening of fathers and partners at 4–6 weeks and 3–4 months postnatal
  • Following perinatal loss (miscarriage, stillbirth, neonatal death)
  • Monitoring treatment response after initiating therapy for PPD
  • Any presentation with sleep disturbance, irritability, or emotional lability in the perinatal period

Formula

EPDS Total = Sum of items 1–10 (each scored 0–3) Forward scoring (0–1–2–3 in order): Items 1, 2 Reverse scoring (3–2–1–0 in order of options): Items 3, 4, 5, 6, 7, 8, 9, 10 Total range: 0–30 0–9: Low likelihood of depression 10–12: Possible depression — further assessment warranted ≥13: Probable major depression — clinical assessment required Q10 > 0: Self-harm risk — mandatory safety assessment regardless of total score

Pearls & pitfalls

  • Question 10 ("The thought of harming myself has occurred to me") must ALWAYS be reviewed and acted upon regardless of total score — it is a safety question, not just a scoring item.
  • The EPDS does NOT distinguish between depression, anxiety, and adjustment disorders — positive screens require a structured clinical interview (e.g., PHQ-9, MINI).
  • An EPDS ≥10 is the recommended threshold for further assessment in most guidelines; ≥13 correlates more closely with DSM major depressive episode.
  • Fathers and partners should also be screened — paternal PPD affects 10% of fathers and impairs child development independently of maternal PPD.
  • The EPDS can be used antenatally — validated for screening during pregnancy from the first trimester.
  • Women with a personal or family history of depression, anxiety, or prior PPD are at significantly higher risk and should be offered more frequent screening.
  • Language barriers and cultural stigma may suppress honest responses — interpreter services and culturally adapted versions improve sensitivity.
  • The EPDS is a screening tool only — it does NOT diagnose postpartum depression. A positive screen must be followed by a clinical assessment.
  • Scoring: Items 1 and 2 are scored 0–1–2–3 (in order). Items 3 and 10 are scored in reverse (3–2–1–0). Items 4–9 are also scored in reverse (3–2–1–0).

Next steps

EPDS 0–9 (Low Risk): Routine care. Reassure and rescreen at next scheduled visit. Provide psychoeducation about PPD symptoms. EPDS 10–12 (Moderate Risk — Possible PPD): Clinical interview required. Explore severity, onset, and duration of symptoms. Counseling/psychotherapy referral. Watchful waiting with follow-up in 2 weeks. EPDS ≥13 (High Risk — Probable Major Depression): Formal psychiatric or psychological assessment. Consider antidepressant therapy (SSRIs are generally safe in breastfeeding). Refer to perinatal mental health services. EPDS Q10 Any Score >0 (Self-Harm Ideation): MANDATORY safety assessment regardless of total EPDS score. Assess suicidality, access to means, and risk of harm to infant. Emergency psychiatric referral if acute risk.
