Using the Edinburgh Postnatal Depression Scale

A core component of Australia’s National Perinatal Depression Initiative (NPDI) is universal screening of all pregnant women and new mums using the Edinburgh Postnatal Depression Scale. The Commonwealth Department of Health and Ageing (DoHA) suggests using it twice – once antenatally, and again a month or so postpartum [reference here]. In Queensland’s public health service, the aim is to use it four times: twice in the antenatal period (usually around 20 weeks, and again midway through the third trimester), and twice postpartum (at 6-8 weeks, and again at 12-16 weeks).

There’s a heap of academic papers about the Edinburgh Postnatal Depression Scale (EPDS), as this simple internet search reveals. This post won’t attempt to replicate such highfalutin work, but just give a few practical tips for clinicians using it.

Tip One: Don’t Believe The Hype

Meaning no disrespect to the authors of the EPDS or those who decided to build Australia’s universal perinatal mental health screening around it, but let’s clearly call the EPDS exactly what it is: a quick and dirty screening tool. Yes it’s been validated in about eleventy-seven different studies, but like all screening tools the EPDS doesn’t pretend to replicate or replace clinical judgement and it certainly doesn’t masquerade as a diagnostic tool. All it does it measure some signs and symptoms of depression and, to a lesser extent, anxiety (more about that in a moment).

The EPDS intentionally limits the screening questions to one week in time. So we need to keep in mind that it’s only takes a snapshot of what’s happening – it doesn’t show us the whole movie. It’s up to the Midwife/General Practitioner/Indigenous Health Worker/Child Health Nurse/whoever to chat with the woman* about whether the snapshot that the EPDS reveals is an accurate glimpse of the big picture. If the woman has had a particularly good or bad week prior to screening the EPDS result will reflect this.

So, when we’re using the EPDS let’s always remind ourselves, and the woman/family we’re working with, that the EPDS isn’t a measure of someone’s psychological strengths or vulnerabilities, nor is it a psychiatric diagnosis. It’s just a reminder, an aidemémoire, that anxiety and depression are pretty common in the perinatal period**, and that we should keep an eye out for some of the common early warning signs.

Tip Two: There’s More Than One Score

Casually (and irreverently) stated, the usual way EPDS results are interpreted goes a bit like this:

  • zero = this person does not trust this service at this time
  • single digits = about what’s expected
  • between ten and twelve = dodgy mood: we had better check-up on the supports in place and arrange to do the EPDS again in a fortnight or so
  • over thirteen = nudge the woman to chat with someone she loves and trusts and/or accept referral for follow-up

That’s pretty good, but we can, and probably should, get a bit smarter about using the results.

Let’s think of the EPDS as four scales.

Yep: four.

The first (most crude) scale is the overall EPDS result [range = 0 to 30]. Interpret as above.

The second (most important) scale is the self-harm/suicide ideation scale: question 10 on the EPDS [range = 0 to 3]. Question 10 asks for a response to the statement, “The thought of harming myself has occurred to me [in the last week]”. If the result is zero that means one of two things: this person hasn’t had thoughts of self-harm recently or this person doen’t trust this service at this time. The response to a score of zero could be something like, “Cool. Just so you know for when you’re chatting to other Mums: it’s not unusual for somebody to feel so overwhelmed that they have uninvited thoughts about hurting themselves. It doesn’t always mean they’re going to do anything silly, of course, but we do like to make sure that they know there are supports available.” Any result on question ten other than zero will require your sensitive, authentic care and some follow-up questions to check on the woman’s safety. Check on whether these thoughts have ever become actions, whether the thoughts are about suicide or non-suicidal self harm, whether there are protective factors in place, and whether this person is safe to go home today (Have you thought about what you would do? When would you would act on those plans?). In my experience people are usually pleased to have an opportunity to speak openly about thoughts of self harm to someone who is caring, not-freaked-out, and non-judgemental. All you’re doing is sensibly, calmly, professionally following-up on a question about depression/risk with the goal of greater understanding.

The third (most ignored) scale is the seven-question depression sub-scale. Questions one and two are fishing around for anhedonia***. Question six seeks to find out whether the woman is feeling overwhelmed, question eight intends to measure mood. Questions seven and nine look to measure for uncharacteristic tearfulness and sleep disturbance. Question ten may be an indicator of feelings of worthlessness. Together, these seven questions measure some of the common neurovegetative symptoms of depression. So, the EPDS depression sub-scale can be expressed as a result out of twenty-one.

The fourth (most handy) scale is the three-question anxiety sub-scale: a measure obtained from scoring questions 3, 4 and 5 in isolation. I find this score out of nine surprisingly useful in clinical practice. Most weeks I’ll get at least one referral where the EPDS total result isn’t very high: say 6 or 7 out of 30. However, a cursory glance at the EPDS reveals that the entire score was generated over just those three questions exploring anxiety symptoms. This transforms a low score into a high score:  6 or 7 out of 30 on the EPDS usually isn’t a big deal, but 6 or 7 out of 9 on the anxiety sub-scale deserves attention.

Confused? Don’t be. Further down the page we will put the four scales into practice using an example EPDS.

Tip Three: EPDS DIY

A spin-off from the beyondblue and beyondbabyblues web sites is the site justspeakup.com.au. There’s some good info there: a first-time Mum I was meeting with earlier this year found Jessica Rowe’s description of her experience of postnatal depression more recognisable, more poignant, and more helpful than anything I said or did. Empowering for her, humbling for me. Sometimes there’s nothing more powerful than sharing stories of the lived experience.

Another good thing about the Just Speak Up site is the self-scoring online version of the Edinburgh Postnatal Depression Scale here: justspeakup.com.au/epds.

If in a room with a PC and it’s appropriate to check the EPDS, you could bring that site up and ask that it be completed (ten mouse-clicks; takes no time) while you busy yourself with another task. Instant scoring! No mathematical challenges or errors! “Shall I print a copy for you to take home or to give your GP?” 

Why not email the justspeakup.com.au/epds link to the woman as a way to promote self-monitoring of changes in mood? If the partner doesn’t quite get with the whole depression/talking about depression thing, suggest that s/he has a go too (it’s fine to use with blokes). You could suggest to the woman that she puts a reminder in her phone to re-visit the EPDS on the first of every month, “You and your partner can compare and contrast scores, if you like. Also, if you’re not sure how to start a chat with your Midwife/GP/Child Health Nurse about your mood you could just print-off the results page and take it in with you to your next appointment… Hey Doc: what do you make of this?

Tip Four: EPDS? There’s an app for that.

There are three iPhone apps that I know of that include the Edinburgh Postnatal Depression Scale (EPDS). NovoPsych is frightfully expensive for the full version so I havent bought it/tried it. SadScale has the EPDS, but it’s kind of… umm… sad. It’s the least attractive iPhone app I’ve ever seen and has a really dodgy email set-up which I’m reluctant to use (no other app has asked me for my email password). The graphing of the results is laughably bad. It’s cheap to try for yourself if you’d like, but I have another suggestion…

Want the EPDS on your phone?

The best app I’ve found so far for the Edinburgh Postnatal Depression Scale is on Mediquations – it’s available for iPhone/iPod Touch/iPad and Android devices for about AU$5. It’s very easy and intuitive to use, calculates the result instantly, and allows you to quickly and easily email the results, including the answer to each of the variables (see below). At least a couple of times a week I’ll hand over my phone the woman I’m meeting with at the time, so we can both compare/contrast today’s EPDS result with previous results. Then I can email the (unidentified) results to my work email address. Why bother? Well, it’s pretty handy to be able to cut and paste the EPDS results directly into the electronic health record, and/or into the letter to the GP, and/or into the follow-up email to the pregnant woman/new mum.

Here’s a cut and paste example of the emailed EPDS result as served-up by Mediquations (for fun: spot the typo on Q9):

Edinburgh Postnatal Depression Scale


Able to laugh and see funny side of things: Not so much now (+1)
Have looked forward with enjoyment to things: Rather less than I used to (+1)
Blamed self unnecessarily when things went wrong: Yes, some of the time (+2)
Been anxious or worried for no good reason: Yes, very often (+3)
Felt scared/panicky for no good reason: Yes, quite a lot (+3)
Things have been getting on top of me: No.  Coping as well as ever (+0)
So unhappy resulting in difficulty sleeping: Not very often (+1)
Felt sad or miserable: No, never (+0)
So unhappy that I’ve been crying: Only occassionaly (+1)
Thoughts of harming self: Never (+0)

Results: Score: 12 Depression: Possible

Sent with Mediquations Medical Calculator for iPhone and iPad.

While we’ve got this example here in front of us let’s revisit the four scales thing and see if we can come up with some info that could guide us in clinical practice:

EPDS = 12/30 [let’s repeat it in a fortnight or so]

Q10 = 0/3 [estimate low risk at present]

Depression Sub-Scale = 4/21 [not very indicative of depression, is it?]

Anxiety Sub-Scale = 8/9 [this person is REALLY anxious]

So, despite being a quick and dirty screening tool, the EPDS can be pretty useful. In the example above we would steer the conversation away from depression and get some information and support with the anxiety instead.

Tip Five: Hate Bagpipes but love Didgeridoo?

From the lofty mountains of science/academia the stone tablets have been handed-down: if you change the questions on a scale it will need to be studied to see if it still has validity and fidelity. In the swampy lowlands of clinical practice we sometimes need to be more pragmatic: if the woman/family we are with don’t understand the wording of a tool written for use in Scotland in the mid-1980s, and/or aren’t all that literate with written English, we need to be adaptive. After all, we’re not doing pure research; we’re doing screening, and we’re doing the best we can with what we’ve got.

One example of how the language of the EPDS can be adapted to be more user-friendly for Aboriginal and Torres Strait Islander women is online courtesy of the Kimberley Aboriginal Medical Services Council; see page 3 of their resource here. I’m not suggesting for a moment that you automatically use this version for every Aboriginal or Torres Strait Islander woman who walks through your door, but it might be a handy reference point for other ways to frame the questions if/when required. There’s probably a lot of non-Indigenous Australians who rather use the style of language of this resource too.

Tip Six: English isn’t for Everyone

Half the fun of travelling overseas is practicing (well, mangling) other languages in pursuit of transport, coffee, toilets, hotel rooms and beer. Using bad translations is fine for that sort of stuff, but it’s pretty dopey to go down that path when looking at something important like emotions or, as per question 10 on the EPDS, about thoughts of self harm.

So, what’s a dude to do? Pull out a translated version: there is a very handy resource with 36 translations into languages other than English. Please note that half of the translations aren’t validated, and have a look at the other tips about working across languages/cultures included on the resource.

Tip Seven: You Are A Tool

I mean that it the nicest possible way.

The EPDS is a static screening tool that was written over 25 years ago in place 15000km away from Australia. It relies on the woman’s literacy and your numeracy to make it work, and even then it’s not replacing your clinical judgement. The EPDS certainly has validity and usefulness, but at the end of the day it’s still just a screening tool and an aide-mémoire.

You, however, are an educated, empathetic, responsive and proactive human being. You have emotional intelligence, a desire to be of use/service, and an incredible capacity to use your communication and life skills in a warm, caring manner. The EPDS can’t compete with you. You are a potent screening tool for emotional distress. You are more subtle and more powerful than ten questions on a form could ever hope to be. You’re a really sophisticated screening tool: please don’t let that dumb EPDS make you leave the best tool available sitting around unused.

Author’s Notes

* Every now and then you’ll see that the term “the woman” is used in this post; there’s an explanation for that. Nomenclature is taken pretty seriously in mental health: years ago the term “patient” was replaced with “client”, which has subsequently been replaced with “consumer” or “service user”. There are other terms that are getting bandied-about and trialled too. Midwives call the pregnant people and new mums they see “women” as a collective noun, or “the woman” if using the de-identified singular. I’m currently working with the same customer group and in the same venues as the Midwives, that’s why I’m speaking their language,

** The definition of “perinatal period” varies quite a bit. For data purposes, the Australian Institute of Health and Welfare defines the perinatal period being from 20 weeks gestation until 4 weeks postpartum. In clinical practice the perinatal period includes all of the antenatal period and (here comes the confusing bit) either up to one, two or three years postpartum. Many clinical services, including the one I’m currently working for, include pre-pregnancy, ie: women preparing for pregnancy.  In everyday use, it’s accurate enough to think of perinatal women as those who are planning pregnancy, pregnant or new mums.

*** Anhedonia is psychobabble jargon for loss of pleasure/joy. Anhedonia is the opposite of being hedonistic. Somebody who is being hedonistic might dance on the tables at nightclubs, shag backpackers, and say “Whoohoo!” a lot. Somebody experiencing anhedonia might still do things that would usually be fun, but just not get much enjoyment from them.

What is social media saying about perinatal and infant mental health this week?

For the last 12 months or so, under the soon-to-be-mothballed @PiMHnurse Twitter handle, I have been using a tool/website called paper.li to collate information into a weekly “online newspaper” called The Perinatal Mental Health Nurse. I’ve now given it a refresh using my new Twitter account/online social media “brand” @meta4RN.

“The Perinatal Mental Health Nurse” is an online newspaper that attempts to answer the question, “What is social media saying about perinatal and infant mental health this week?”

The purpose of The Perinatal Mental Health Nurse is to attempt to answer the question, “What is social media saying about perinatal and infant mental health this week?”. To flush-out that answer, Twitter, Facebook & Google+ are being used as the data sources, and these search terms have been set: “perinatal mental health” and “infant mental health”. To add a little local and mental health nursing flavour, the terms “ACMHN” (abbreviation/hashtag for “Australian College of Mental Health Nurses”) and “HCSMANZ” (abbreviation/hashtag for “Health Care Social Media Australia & New Zealand”) are also searched on Twitter.

[Addit. 28th November 2012] An additional search term has been added: “#bePNDaware”; this hashtag had strong uptake on social media during Australia’s Postnatal Depression Awareness Week (more info about that here).

The beauty of using paper.li is that it is one of those set-and-forget tools which, at first blush, seems kind of magical and empowering: “Who needs Rupert Murdoch? I just made my own newspaper!” Just set the sources and search terms and paper.li does all the rest for you. How much does it cost? Nothing. How much time does it take to set up? Not much; less than half an hour. However, over time too-frequent updates can become a bit tired, just part of the background noise, the flotsam and jetsam of Web 2.0. Hopefully with The Perinatal Mental Health Nurse the “noise” won’t be too intrusive – the updates have been set to just once a week (Wednesdays at 6.00am, Cairns time), which will be accompanied by an automagical Twitter and Facebook anouncement.

I hope that you’ll find some items of interest in The Perinatal Mental Health Nurse. If not, why not see if there are other paper.li online newspapers that are more to your tastes or, better again, start your own?

One last thing. If you’re looking for a more thoughtfully and academically curated compilation of information regarding perinatal and infant mental health, the best website that I know of is the Perintal and Infant Mental Health LibGuide

Deploying complex information via a QR Code

The Health Roundtable

The Health Roundtable hosted the Innovation Workshop and Awards in Sydney on 11th and 12th October 2012. David Dean, General Manager of The Health Roundtable, endorsed the views of Futurist Tim Longhurst who said, in his lively and entertaining opening Keynote, “It’s not enough to say it anymore. It’s not enough to publish it anymore. Post it. Get it online. Sharing is the rent you pay for using the internet.” It is with those words echoing in my ears that I have posted a YouTube version of my poster presentation (it’s my first time at this – I’m not all that happy with the visual quality of the video, but want to get it online sooner rather than later).

There were 16 concurrent sessions grouped into 4 streams at the conference. In each session participants were asked to vote for the poster presentation which provided the most useful ideas for implementation at their service. At the end of the conference a summary of all session winners was presentated, and participants were again asked to vote on the idea their health service would be most likely to utilise – this yielded four awards: one for each of the four conference streams.

2012 Innovation Award

That’s me on the left, grinning like a Cheshire Cat. Presenting the Health Roundtable 2012 innovation Awards is Dr Nigel Lyons, Chief Executive of The Agency for Clinical Innovation.

My presentation, “Deploying complex information via a QR Code” won the 2012 Innovation Award in the “Improving Quality of Patient Care” stream of the Health Roundtable’s Innovation Workshops and Awards. Naturally, I am thrilled with the award – it carries prestige and is worth $6000 to the health service that employs me. It is also quite humbling because this certainly wasn’t the “best” idea in terms of sophistication, complexity or outcome – many of the other ideas presented have made more significant acheivements in regards to the quality of patient care, in my view. However, the feedback was that the no-cost/low-cost nature of using QR Codes, the simplicity of implementation, and the ability to apply them to a number of different uses in a number of different settings, made this an idea that could easily be adopted and adapted by many health services. This reflects the stated objective of the Innovation Workshop and Awards: “Shamelessly steal at least one good idea to take back to your health service and use”.

Alternative ideas for using QR Codes in health care seetings include:

  • put a QR Code on a piece of equipment; scanning the code takes the user directly to procedure for using that equipment (procedures will be online)
  • put a QR Code on appoinment letters; scanning the code gives directions to where the appointment will be (using geolocation/the smartphone’s map function)
  • put a QR Code on the closed clinic/office door; scanning the code puts the alternative phone number and/or address straight on to the user’s phone
  • put a QR Code on brochures/posters; this keeps visual clutter on the print version to a minimum, but allows the user to get further information/contact details PRN

Let’s not overstate the utility of QR Codes – they won’t be an effective tool for every demographic group, and certainly won’t replace the written word/existing methods of communication. However, with a little bit of imagination, you might be able to find an application for QR Codes that will enhance your workflow/workplace. Have a look at the YouTube video above if you’re still unsure what this is all about.


Joe Petrucci and Kevin Freele of the Cairns & Hinterland Mental Health Service for introducing me to The Health Roundtable earlier this year.

Marion Dixon and Pieter Walker, who are both with The Health Roundtable team, gave very strong encouragement to bring the idea to Sydney. I certainly would not have had the confidence to present the idea to my peers without their encouragement, so hope that Pieter and Marion feel very much a part of the success of the presentation and the 2012 Innovation Award.
