8.3 Postpartum Mood & Anxiety Disorders: Screening With the Edinburgh Scale

Why This Topic Matters

A CLC often sees a new mother more frequently, and more informally, than any other professional in the fragile first weeks after birth — which puts counselors in a unique position to notice a mood or anxiety problem developing. The ALPP Academic Content Checklist tests this directly under General Principle I, Task 4: "mood and anxiety disorders in the post-partum period, including the use of tools for assessment (i.e. Edinburgh Postnatal Depression Scale)." Expect the exam to test both the clinical picture — telling baby blues, postpartum depression, and postpartum psychosis apart — and the mechanics of the screening tool itself, alongside the firm boundary of CLC scope: screen and refer, never diagnose or treat.

Three Conditions, Three Timelines

Baby blues are extremely common — studies put the rate as high as 50-80% of postpartum women — and require nothing more than reassurance. Postpartum depression, by contrast, is estimated to affect roughly 1 in 7 to 1 in 8 postpartum individuals and needs professional treatment. Postpartum psychosis is rare, on the order of 1-2 per 1,000 births, but is a true emergency requiring the same urgency as any acute safety risk.

The Edinburgh Postnatal Depression Scale

The Edinburgh Postnatal Depression Scale (EPDS) is the validated screening tool named in the ALPP checklist. Know its mechanics cold:

• 10 items, each scored 0-3, for a total possible range of 0-30.
• A score of 10 or higher is commonly used as the threshold to warrant further clinical assessment.
• A score of 13 or higher is commonly interpreted as indicating probable depressive illness.
• Item 10 asks specifically about thoughts of self-harm. Any nonzero response on Item 10 requires an immediate safety response, regardless of the total score, because it can signal risk even when the overall score looks reassuring.

The EPDS was designed and validated specifically for the postpartum period (it also has validated prenatal use), which distinguishes it from general-population depression scales that were not built for the physiological and situational context of a new mother.

The Bidirectional Link With Breastfeeding

Breastfeeding difficulty and mood disorders influence each other in both directions. Pain, latch problems, or perceived insufficient milk supply can trigger or worsen anxiety and depression; conversely, depression and anxiety can erode a mother's confidence and motivation to continue breastfeeding. A CLC who recognizes this link watches for mood symptoms during ordinary lactation visits, not only when a mother volunteers them.

Staying Within CLC Scope

When a CLC notices signs of a mood or anxiety disorder, the correct response is to acknowledge the mother's feelings with empathy, use a validated screening tool if it is part of the practice's protocol, and refer promptly to her physician, obstetric provider, or a mental health professional — never to diagnose or prescribe. A critical exam trap: telling a mother to stop breastfeeding is not an appropriate response to suspected depression. Most commonly used antidepressants are compatible with continued breastfeeding (verifiable through resources such as LactMed), and whether to continue nursing while being treated is a decision for the mother and her prescriber — not something the CLC should decide or suggest unilaterally. Any indication of thoughts of harming herself or the infant, or any sign of psychosis, requires immediate escalation: do not leave the mother and baby unsupervised, and connect her to emergency mental health resources the same day.

Risk Factors and Why CLCs Are Well Positioned to Notice

Known risk factors for postpartum depression and anxiety include a personal or family history of depression or anxiety, a traumatic or complicated birth, lack of social or partner support, a colicky or medically complex infant, sleep deprivation, and — directly relevant to a CLC's daily work — persistent, unresolved breastfeeding difficulty. Because a CLC often visits or calls a family repeatedly across the first days and weeks, and asks detailed questions about sleep, feeding frequency, and how the mother is coping, subtle changes in mood, energy, or affect are frequently visible to a CLC well before a mother mentions them at a routine obstetric or pediatric visit. This is precisely why the ALPP blueprint places a screening tool inside a lactation-counseling competency rather than treating mental health as someone else's job entirely: the CLC's role is not to become a mental health provider, but to be the trained observer who reliably closes the referral loop.

Exam Scenario: The Score That Looks Reassuring

A mother completes an EPDS during a routine two-week lactation follow-up. Her total score is 7 — below the commonly used cutoff of 10 — but she circled "Yes, quite often" on Item 10, the self-harm item. A candidate who stops at "the total score is below cutoff, no action needed" will miss this item. The correct action is to treat the nonzero Item 10 response as an independent trigger for immediate safety follow-up regardless of the reassuring total score: ask directly and calmly about her safety and the baby's safety, do not leave her alone if there is any immediate concern, and connect her to same-day psychiatric or crisis support. This is one of the exam's clearest illustrations of why the CLC must know the EPDS's internal structure, not just its overall cutoff numbers.
