Psychological well being challenges that come up, proceed, or intensify throughout being pregnant and all through the primary 12 months after delivery are generally known as ‘perinatal psychological well being difficulties’ (Howard et al., 2018). These situations are comparatively frequent, with analysis suggesting they have an effect on as much as 27% of birthing mother and father (most frequently moms) in high-income nations (Division of Well being and Social Care, 2024). Such difficulties are linked to vital destructive penalties for folks, infants, households, and society as a complete (Stein et al., 2014).
In response to the rising charges of perinatal psychological well being issues skilled by mother and father within the UK, there was vital authorities funding into the creation of specialist group perinatal psychological well being companies throughout the nation. These companies intention to focus on roughly 10% of birthing mother and father experiencing advanced psychological well being difficulties (Alderwick & Dixon, 2019; Keynejad, 2024).
One of many interventions obtainable at such companies is the Circle of Safety Programme (COS-P; Powell et al., 2013). Comprised of 10-20 group periods, the programme goals to improve safe attachment between father or mother and baby. A earlier meta-analysis discovered that COS-P had a medium to massive impact on safe attachment, high quality of caregiving, caregiver self-efficacy and caregiver despair (Yaholkoski, Hurl & Theule, 2016).
The current research represents the primary randomised managed trial to discover the scientific effectiveness of the Circle of Safety programme when delivered as a part of NHS group perinatal psychological well being companies. Particularly, the research aimed to discover the impression of COS-P on:
- Parental psychological well being
- Guardian-infant bonding
- Parental emotion regulation
- Little one improvement outcomes
- Parenting sensitivity
- Little one attachment

Round a 3rd of birthing mother and father expertise perinatal psychological well being difficulties. Might the Circle of Safety programme be useful to those mother and father?
Strategies
This research was a “pragmatic, multicentre, randomised, assessor-masked, parallel-arm managed trial”. So, the research was pragmatic (it was delivered in a real-life NHS setting), multicentre (it included 10 geographically unfold websites throughout England), randomised (contributors had been randomly assigned to both COS-P or remedy as traditional), assessor-masked (these gathering information didn’t know who had acquired which remedy) and parallel-armed (that’s, every participant remained of their assigned group all through the trial).
Eligible contributors for the research had been birthing mother and father with clinically indicated psychopathology and bonding difficulties who had been aged 18 or above, not utilizing substances and parenting an toddler youthful than 1 12 months with out extreme sickness or developmental issues. Those that had already acquired COS-P or who had been experiencing psychosis had been excluded from the trial.
For these receiving COS-P, 10 weekly periods got by a psychological practitioner. Classes had been performed in particular person the place attainable, although the bulk had been on-line. Individuals accomplished questionnaires previous to the intervention, then at 3 months, 7 months and 12 months post-baseline. The first final result measure, the Medical Outcomes in Routine Analysis-Consequence Measure (CORE-OM), is a 34-item measure of psychological misery chosen by the Professional by Expertise panel who had been closely concerned within the research from begin to end.
Outcomes
Out of three,171 birthing mother and father screened, 2,785 (88%) had been ineligible. In complete, 371 contributors had been randomised to the research; 248 had been assigned to COS-P remedy, whereas the remaining 123 had been assigned to treatment-as-usual. After accounting for these with lacking information, the ultimate contributors included in evaluation had been 194 within the COS-P arm and 100 within the treatment-as-usual arm. Individuals had been primarily white females of their early 30’s which was largely consultant of the inhabitants attending every remedy web site. Individuals attended a median of 6.5 out of 10 periods.
When it comes to the outcomes assessed:
- Parental psychological well being improved considerably in each teams over the 12 months (from reasonable to gentle), however there was no distinction between those that acquired COS-P and people who acquired treatment-as-usual.
- Guardian-infant bonding improved considerably in each teams over the 12 months (from above to beneath the edge for bonding issues), however there was no distinction between the 2 teams.
- Parental emotion regulation confirmed better enhancements within the COS-P programme at 3 and seven months, although at 12 months outcomes favoured treatment-as-usual. Of observe, imply scores for emotion regulation remained above the scientific threshold in any respect timepoints for each teams.
- Little one improvement outcomes – no significant variations had been discovered between teams or throughout timepoints.
- Parenting sensitivity – COS-P contributors confirmed considerably better enhancements at 7 months, although these weren’t maintained at 12 months.
- Little one attachment – no vital variations had been discovered between teams, or throughout timepoints.
A complete of 134 adversarial occasions had been reported amongst 73 contributors, representing 20% of all contributors. Of those, 12 occasions had been categorized as critical adversarial occasions, with one decided to be associated to the trial intervention. Of the 134 adversarial occasions, 99 had been reported by contributors within the COS-P arm of the trial.

Circle of Safety didn’t result in vital enhancements in parental psychological well being or bonding over and above treatment-as-usual.
Conclusions
The authors conclude that:
The outcomes of this research confirmed that when the COS-P plus treatment-as-usual intervention was delivered inside NHS group perinatal psychological well being companies in a predominantly on-line format, it was not considerably more practical than treatment-as-usual alone in decreasing perinatal psychological well being difficulties over a 12-month follow-up interval.
Once I got here throughout this paper, I merely needed to put my hand as much as weblog it. I’m at the moment 6 months postpartum and midway by means of receiving the Circle of Safety programme, so I used to be eager to get some spoiler alerts and see what the proof stated concerning the circle that I’ve come to know so nicely. To say I’m shocked (and considerably disillusioned), to study of those null outcomes is an understatement. The next sections of the weblog mix my educational data with my private expertise and are primarily my musings concerning the two, so please indulge me.

The jury is out on Circle of Safety: trial outcomes discovered that it had no profit over and above treatment-as-usual.
Strengths and limitations
That is clearly a meticulously designed research that has greater than earned a coveted spot within the extremely esteemed journal: The Lancet Psychiatry. Particularly, I used to be struck by how this research manages to realize that uncommon present of balancing rigour with humanity; guaranteeing adherence to gold-star scientific requirements, while nonetheless creating house for these with lived expertise to be heard inside the research design. I notably welcomed the inclusion of a scientific search that outlined what we already know concerning the COS-P and the way this research provides to the present data base.
That being stated, considering my private expertise of parenting and the COS-P, there are just a few methodological selections that I’m inquisitive about. Firstly, for me, the main final result of selection is attention-grabbing. The COS-P intervention goals to enhance attachment and bonding between toddler and caregiver, and while it’s completely believable that this, in flip, might result in improved psychological well being outcomes, the deal with psychopathology as a main final result appears odd. In my very own expertise (N of 1), the COS-P has been targeted far more on outcomes which can be relational than particular person. As an example, I really feel that the programme has infinitely improved my sensitivity to my child’s wants and thus, by definition, has improved my bonding and attachment.
The way in which by which final result measures are chosen in trials is one thing that I discover deeply fascinating (not one thing I are inclined to reveal on a primary date). The survivor motion has lengthy been arguing for final result measures which can be outlined by these with lived expertise, noting that these are sometimes completely completely different from those chosen by researchers (see Faulkner, 2017; Hemming, 2025). Nonetheless, on this case, that’s exactly what the authors have finished. It acquired me considering extra broadly about how final result measures can greatest be decided – at its core, we’re counting on a small group of people (on this case an professional by expertise panel, however mostly a gaggle of researchers) to find out what a very powerful outcomes are to the lots of (or hundreds) of individuals accessing interventions. Can we actually anticipate such a choice to be consultant of such a various inhabitants?
Secondly, I wish to spotlight some ideas concerning the contributors within the research. The eligibility standards require that contributors are parenting an toddler of 12 months or underneath, usefully reflecting my very own expertise of endeavor COS-P. While I absolutely help the thought of giving the programme earlier to oldsters to assist forestall points with attachment slightly than treating them down the road, in my very own expertise I’ve discovered that a number of the content material of the programme is not all the time relevant to this younger age group. Because the authors themselves observe, a lot of the primary 12 months of life is about feeding, sleeping and adjusting to modifications in household life (or as I like to consider it, merely about conserving myself and the child alive), and a deal with parental psychological well being, or attachment and bonding could, sadly, be a ‘nice-to-have’ on this stage of life. I’ve typically discovered myself interrogating the facilitator about how the included video content material applies to a a lot youthful child. For my part, it’s a lot simpler to know how a strolling, speaking baby would possibly discover their world and are available again to their father or mother for safety, however such a cycle will be a lot tougher to identify in an toddler child whose interactions with father or mother and the world consist primarily of cries that the father or mother has to decode and interpret. Relatedly, I’m curious whether or not contributors had been first-time mother and father or not. Being a first-time father or mother myself, it strikes me that those that have already been by means of this life-changing expertise as soon as earlier than, might need a longer-term outlook on bonding and attachment and, due to this fact, could have acquired the programme in another way to first-time mother and father.
My closing thought on the design of the research is whether or not the timeframe is lengthy sufficient to discover outcomes resembling attachment. While a 12-month follow-up is a implausible achievement in a realistic trial resembling this one, I can’t assist however marvel if we’d like even longer nonetheless to see the advantages of the COS-P when it comes to attachment and bonding. Bonding is a two-way road, and it’s one thing that incrementally grows over time and I think about (and hope) will proceed to develop exponentially past 12 months. Maybe an prolonged longitudinal research would possibly do a greater job of exploring the consequences that the COS-P can have on attachment, that I really feel possibly can’t be seen in simply 12 months of life.

This research manages to realize that uncommon present of balancing rigour with humanity; guaranteeing adherence to gold-star scientific requirements, while nonetheless creating house for these with lived expertise to be heard inside the research design.
Implications for follow
One factor that struck me as attention-grabbing was the accessibility of the programme within the UK in comparison with in Australia, the place I reside and obtain COS-P. Right here, no less than in Victoria, all mother and father can entry the Circle of Safety free of charge by way of their native council who run group programmes a number of occasions a 12 months. Along with this, these thought-about to be at a better threat of perinatal psychological well being difficulties (myself included on this class) can obtain one-to-one supply of the programme on the particular person’s home with a skilled clinician. I discover it attention-grabbing then, that within the UK, COS-P is offered solely to these in contact with a group perinatal centre, which excludes i) those that are experiencing perinatal psychological well being issues however are not related with a group centre and ii) those that are usually not (but) experiencing perinatal psychological well being issues.
The research studies that contributors had been predominantly White females of their 30’s (which by the way precisely describes me), and this was largely consultant of the broader populations accessing the group perinatal centres. That is fairly a homogenous group of individuals, and I can’t assist however wonder if COS-P would possibly result in better outcomes in extra various populations. As an example, I’m eager to know extra concerning the impression of COS-P on birthing companions. Certainly, my husband has been finishing the COS-P together with me and we’ve discovered it extraordinarily helpful to have a shared language with regards to fascinated by our relationship with our son (and infrequently with each other too).
Additional, after I take into consideration this accessibility with a stigma lens, I discover it attention-grabbing that the programme is barely obtainable to these thought-about to have pre-existing difficulties already (e.g. sufficient to already be in contact with a group perinatal centre). I’ve had a troublesome postpartum journey, and must admit that I’ve, at occasions, felt considerably ashamed of needing to ask for extra help, notably with regards to issues like bonding with my son which largely is predicted of moms to occur naturally and effortlessly. Six months down the observe, I’ve modified my stance on this altogether and slightly than being ashamed to ask for assist, I’m as a substitute extraordinarily grateful for the help that’s on provide and take it as simply that; help. Not a judgement of my means as a father or mother, nor on my psychological well being stability, however merely a serving to hand to information me by means of what has been one of many steepest studying curves of my life. It’s true what they are saying, infants actually don’t include a handbook. However providing a programme like COS-P would possibly come near this.
My different remark is concerning the mode of supply. While the authors draw on analysis which proves that parenting interventions delivered on-line present comparable outcomes to face-to-face programmes (Spencer et al., 2020), there’s something extremely useful about having a practitioner in your individual home observing your relationship together with your child and giving professional scientific steering on simply this.
I’m, in fact, getting forward of myself right here. Giving such widespread (and expensive) entry to a programme that has not confirmed useful past treatment-as-usual might be thought-about illogical. Certainly, I’m considerably shocked to study of the comparatively low evidence-base for a programme that’s so generally carried out right here in Australia. And while this trial is a particularly nicely performed piece of analysis, I’d implore you to suppose past these outcomes and contemplate the broader factors I’ve highlighted. I fear that the authors’ conclusion is considerably definitive – that the NHS ought to not proceed to supply COS-P as an intervention. However it’s price contemplating whether or not just some tweaks to who’s accessing the programme, or the best way it’s delivered, or the measures by which we deem it to be ‘profitable’ might result in a wholly completely different story. And if not, then what’s the subsequent greatest obtainable proof? It appears somewhat myopic and dichotomous to conclude that the programme shouldn’t be carried out.
Assertion of pursuits
While I wouldn’t have any official conflicts of curiosity to declare, I do suppose it’s price highlighting the bias that I maintain in that I’ve discovered the Circle of Safety programme to be extraordinarily useful in my very own private life. I hope that I’ve managed to convey this, while nonetheless portraying an goal account of the research, its findings and its limitations.
