Misdiagnosis Equals Mistreatment – Why Then Does NHS Talking Therapies Eskew Diagnosis?

The NHS Talking Therapies Manual (2023), p24 indicates that reliable diagnosis is not part of a ‘good assessment’. Yet paradoxically, it states that clients with PTSD or social anxiety disorder should not be offered low intensity interventions first. This begs the question, of how a clinician would know, which level of stepped-care was appropriate without making a reliable diagnosis. Its’ clinicians apparently have magical insight, in that they can determine from the ‘presenting mental health problems’, the appropriate National Institute for Health and Care Excellence (NICE) protocol.  But NICE clearly states that its’ recommendations are predicated on a reliable diagnosis. NHS Talking Therapies attempt to force a square peg into a round hole is risible.

To give a further example of the Services misdiagnosis consider the following.The Service rejects referrals with a psychosis label. It does not stop long enough to carefully consider whether the label is misplaced. Mr X was a casualty of this –  a series of mental health professionals, over a period of 7 years, declared that he was a paranoid schizophrenic, each uncritically accepting the label applied by their contemporaries. NHS talking therapies declined to treat him. Finally, he was seen by a clinician who expressed his total bewilderment at the historical diagnosis, and concluded that he was suffering from obsessive-compulsive disorder, obsessive type. He successfully treated Mr X for the OCD using a standard protocol for obsessions. The Service engages in a game of ‘pass the bomb’ when it comes to certain labels.

NHS Talking Therapies has nothing in place to protect a person against the ‘slings and arrows’ of outrageous diagnoses. The de facto missive of the British Association for Behavioural and Cognitive Therapies (BABCP the CBT Lead Organisation) is to ‘suffer’ these ‘slings and arrows’, reliable diagnosis is not part of any of its approved training courses. There is no sense of ‘taking up arms’ against misdiagnosis, even though its’ former Presidents are well aware of the importance of diagnosis. Their overriding concern, is it appears, the wider dissemination of services. Which is perfectly laudable in itself. But any good has to be contextualised, it was perfectly right in the early twentieth century to seek to redistribute wealth, but not as in Stalinist Russia, at the expense of reverence for the individual and honesty. It is difficult to escape the view that BABCP and for that matter, the British Psychological Society (BPS), are on a ‘mission’, that needs contextualising.

‘No Direct Evidence of The Effectiveness of NHS Talking Therapies’

If you disagree, please supply the evidence. The justification for NHS Talking Therapies rests solely on indirect evidence. Primarily the randomised controlled trials cited by the National Institute for Health and Care Excellence (NICE) for depression and anxiety disorders. But there is no assurance (fidelity checks) that these protocols have been accurately translated into routine practice. NHS Talking Therapies legitimate themselves by claiming NICE compliance. Whilst this might be excellent marketing, there is no evidence to substantiate it. Further the randomised controlled trials are themselves of variable quality. In a minority of trials there has been blind independent assessment. In principle the high-intensity NHS Talking Therapy Service could have the capacity to deliver these evidence-based treatments. But there is no evidence that this has actually happened – a gap between theory and practice. By comparison the low intensity NHS Talking Therapy Service has the reference base of relatively poor quality studies. Not only is there the problem of a dirth of evidence of compliance with a NICE approved protocol, but the foundations of the low intensity protocols are weak.

All manner of interventions can be made to appear great in theory. But the acid test is what happens in the real-world. Disinterest in this, paves the way for vested interests, whether they be Organisations or charlatans marketing their wares. Organisations readily adopt a volume approach, operational matters: numbers seen, waiting times, become the key performance indicators, with a blind eye turned to value. NHS Talking Therapies acts it seems in its’ own interest and the client does not get a look in. One might ask how matters have reach such an impasse? Professional bodies such as British Association for Behavioural and Cognitive Psychotherapy (BABCP) and the British Psychological Society (BPS) have advanced NHS Talking Therapies mission at every turn.They have totally failed to critically appraise NHS Talking Therapies.

The National Audit Office Confers With Mental Health Powerholders and Not Patients

Unsurprisingly the surveyed integrated care board (ICB) mental health leads and mental health trusts tell the NAO what a great job they are doing.  The NAO also interviewed mental health stakeholder organisations such as the BPS and BMA. On this basis, the NAO [“Progress in improving mental health services in England”] declared last month, that ‘the government has achieved value for money’. The yardstick used by the NAO was whether the surveyed bodies ‘met ambitions to increase access, capacity, workforce and funding for mental health services’. No attempt to access the voice of the people. 

Interestingly the NAO did not even attempt to make the claim of the prime movers in IAPT Layard and Clark (2015) that the Service costs nothing, due to savings on welfare benefits and physical healthcare costs!  The response of the great and the good in mental health (the NHS Confederation, SANE and Mind) has been, that the report highlights the need for increased funding, to recruit and retain more staff. No awareness that more of the same is unlikely to make any difference to patients.


The report reveals that £752 million was spent on NHS Talking Therapies predecessor, IAPT, in 2021-22. But when the NHS acquired IAPT earlier this year no audit of the latter was conducted. No business would behave in this way. Yet the NAO report re-iterates the target of ‘at least 50% achieve recovery across the adult age group’. No mention that there is no independent evidence that this has ever been achieved. With the best evidence Scott (2018) suggesting that only the tip of the iceberg recover. What sort of auditors are the NAO? Under their watch acquisitions can be made without credible scrutiny.

In 2018 the NAO jettisoned an enquiry into the Improving Access to Psychological Therapies (IAPT) Programme. In response to a Freedom of Information request, the NAO responded on February 17th 2020 ‘We commenced work on the IAPT programme in 2017-18. However, the work on this programme was curtailed in June 2018 by the Comptroller and Auditor General (C&AG) of the time in response to changing priorities. The alterations to the work programme were made so that the C&AG could respond quickly on important topical issues, such as work on the UK’s exit from the European Union, the government’s handling of the collapse of Carillion, and on significant NHS spending increases in 2017- 18 on generic medicines in primary care’.

The Near Extinction of CBT

Evidence-based psychological therapies are near extinction. Their demise began in 2008 with the inception of the Improving Access to Psychological Therapies (IAPT) service. Aided and abetted by the British Psychological Society’s validation of IAPT’s Psychological Well-being Practitioner’s (PWPs) training programmes and the service’s fellow traveller, the British Association for Behavioural and Cognitive Psychotherapy (BABCP). Gone is the welcoming open door and the careful distillation of what ails the client, instead there is a 30 minute+ telephone conversation, with a third of people then not going beyond one treatment appointment.


The public most commonly receive PWP ministrations when they seek NHS psychological help. But the PWP’s do not follow any treatment protocol for any disorder, indeed they do not make diagnoses. How then can they be said to deliver CBT? By the spurious claim  that they can select a CBT strategy which is sufficiently potent. But they furnish no evidence of systematically following any strategy, notwithstanding that there is no evidence that CBT strategies delivered as stand alone interventions make any real world difference. The PWP’s deliver the Alice in Wonderland, Dodo verdict on CBT strategies ‘all are equal and must have prizes’. Raising the question ‘is CBT as dead as the Dodo?’



Where else might CBT be found? It is not impossible for it to be delivered in IAPT’s high intensity service, but few of its practitioners conduct a reliable standardised diagnostic interview which is the foundation for delivering CBT.  The  treatment integrity of high intensity CBT interventions has never been assessed.  No steps have ever been taken to ensure clinicians are dovetailing diagnosis appropriate treatment targets with matching treatment strategies. Is CBT to be found in private practice? It is possible, but private organisations have largely sought to ape IAPT in the mistaken belief that this confers credibility. Are the chances of finding CBT in private practice comparable to finding life on Mars?

Is CBT alive and kicking in secondary care? Here we enter the muddy waters of clients who might traditionally be regarded as having personality disorders (PD). But there is an understandable reluctance to use the term PD because of the associated stigma and because historically use of such a term has consigned people to the dustbin. Nevertheless Sperry and Sperry (2016) have produced the 3rd Edition of CBT for DSM-5 Personality Disorders (Routledge) but it is eminence-based rather than evidence-based. It is light on outcome studies. I struggled to find any where there was independent assessment of outcome by blind raters, use of an outcome measure that clients would regard as a minimally important difference and evaluations by those other than the creators of the protocols. It is a free for all with strategies such as ‘thought stopping’ recommended, without specification of any contraindications such as PTSD or OCD. Only eclipsed by recommending solution focussed therapy for anxiety. If clinicians in secondary care operate on this text it is very different to Beck’s own work on CBT for personality disorders. But no typology of what clinicians say they do and what they actually do in secondary care has been produced. Tertiary care seems preoccupied with crisis management and is not guided by any recognisable CBT protocol.

In neither primary or secondary care is there a differentiation of treatments or clients. Thus in the UK it is impossible to answer the question of ‘What Works With Whom?’. This leaves clinicians up a creek without a paddle.

Dinosaurs may have been wiped out by an asteroid hitting the earth 66 million years ago, but life survived, doubtless CBT will survive the impact of IAPT, but it is a close call and it is likely going to be down to individual practitioners doing what they know to be best for their clients.

Low Intensity CBT Works ‘Just like That’

as the magician Tommy Cooper would have said. The Improving Access to Psychological Therapies Service (IAPT) invites its’ paymasters Clinical Commissioning Groups (CCGs)/NHS England to fund a simple and cheap solution to mental health problems. If it sounds too good to be true, it probably is. But this hasn’t stopped IAPT becoming the over a £1bn a year magnet for investment and all without independent assessment.

Here is an extract from a Psychological Wellbeing Practitioner’s (PWP) letter to a GP:

Stress Control Course undertaken outcome was successful evidenced by the first and last questionnaire




Nov 2018



Jan 2019



The PWP is unaware that a score on a psychometric test is not an evidence-based construct. Such scores are not specific to anything. They cannot be used as a surrogate for a diagnosis.  ‘Stress’ is a fuzzy, the terms usage in this context, resembles Alice in Wonderland where words mean whatever you want them to mean.  Further, a change in the score is not evidence that the person’s needs have been met.

The mechanism’s of action in the original randomised controlled trials of CBT for depression and the anxiety disorders were clearly stipulated. As were outcomes e.g loss of diagnostic status as assessed by independent clinicians. But in the low intensity interventions there is no specification of an evidence-based mechanism for change. In effect we are invited to believe in the magic, it works just like described in the letter abstract. One can only gasp at the incredulity of CCGs and wonder what agenda they are working on. But the British Association for Behavioural and Cognitive Psychotherapy (BABCP), the ‘Lead’ organisation for CBT practitioners has a special section for PWPs and IAPT rejoices that its’ low intensity CBT courses are validated by the British Psychological Society. They have failed clients abysmally.

Another Nail In The Coffin of IAPT

A year ago the British Journal of Clinical Psychology published my paper ‘Ensuring that the Improving Access to Psychological Therapies (IAPT) programme does what it says on the tin’  60(1), 38. This month in the Journal there is a further damning indictment by Martin et al (2022) ‘Improving Access to Psychological Therapies (IAPT) has potential but is not sufficient: How can it better meet the range of primary care mental health needs?’ 61, 157–174, DOI:10.1111/bjc.12314.

Here are the main points from Martin et als’ BJCP paper:

  •  Improving Access to Psychological Therapies(IAPT)has significantly increased access to psychological therapies within primary care over the last decade, though it is unclear whether its interventions are sufficiently tailored to meet the actual levels of complexity of its clientele and prevent them from needing onward referral to secondary care as originally envisaged.
  •   Given the ongoing focus on and investment in IAPT informed developments into long-term conditions and serious mental illness, this review considers whether additional elucidation of the model’s original objectives is required, as a precursor to its expansion into other clinical areas.

  •   There view indicates that there is a stark lack of data pertaining to the generalisable, real-world clinical benefits of the IAPT programme as it currently stands.

  •   Recommendations are provided for future areas of research, and practice enhancements to ensure the value of IAPT services to clients in the wider context of NHS mental health services, including the interface with secondary care, are considered.


The British Association of Behavioural and Cognitive Psychotherapies (BABCP) ought to look seriously at the promotion of its’ IAPT comic ‘CBT Today’. Interestingly in its’ recent issue it managed to omit that I was one of those who made a submission re: the proposed NICE Guidance on depression. Further, only one of the others who made submissions were given their adjectival title, the leading light in IAPT. The British Psychological Society (BPS) should reconsider its validation of low intensity IAPT courses, in the absence of any credible evidence base on real-world effectiveness.

The Extraordinary Claims and Behaviours of IAPT’s Backers

who exhibit power without accountability. They include companies such as SilverCloud and limbic and professional bodies such as the British Association for Behavioural and Cognitive Psychotherapy (BABCP) and the British Psychological Society (BPS).

I reported SilverCloud to the ASA over its claim of ‘up to 70% clinical recovery rates’ for its computerised CBT. Unfortunately they could not act on it as it comes under Irish jurisdiction. The matter has  been passed to the Irish ASA, from whom I have heard nothing. The reach of SilverCloud is extensive, with its’ claim to be “supporting 80% of the NHS Improving Access to Psychological Therapies(IAPT) services”. It is a major financial backer of IAPT workshops. But there has been no independent verification of SilverCloud’s claimed recovery rates.

IAPT workshops are also now funded by limbic ‘An A. I. assistant for clinical assessment in IAPT – improving access, reducing costs and freeing up staff time’. Recently the British Psychological Society Journal the Psychologist devoted an article to the claims of the CE0 of limbic. I protested, and furnished a critique which the Editor declined. I note that in the current issue of the American Journal of Psychiatry that there is a paper by IAPT researchers Delgadillo et al 2022 JAMA Psychiatry. 2022;79(2):101-108. doi:10.1001/jamapsychiatry.2021.3539 published online December 8, 2021 in which they have been unable to substantiate the claims of limbic.

But Delgadillo et al (2022) do claim a 7% increase in the likelihood of recovery if IAPT therapist use the limbic algorithm i.e inputting data on depression, anxiety, history etc to determine whether the particular clients needs are better met by IAPT standard stepped care or by a stratified procedure where clients are allegedly better matched to high or low intensity CBT initially. However they do observe that the apparent difference could be due the therapists involved in stratification devoting more time to clients!

Delgadillo et al (2022) accept without question IAPT’s definition of recovery, a change of score on a self-report measure, the PHQ9, to below caseness. They fail to point out that their metric does not a) involve independent assessors to counter the demand characteristics involved in usage of a self-report measure i.e the focus on this measure in client-therapist interactions b) the IAPT data provides no indication that clients see the claimed changes as clinically meaningful, i.e back to old self or best functioning c) symptoms of depression and anxiety wax and wane, so that any improvement on a self-report measure can be simply a flash in the pan, particularly when people present initially at their worst. It has to be determined that any change is lasting e.g at least 8 weeks. It appears that Delgadillo et al (2022) simply rejoice in the large data set furnished by IAPT, it is a case of ‘never mind the quality, feel the width’.

When the power holders collude in this way, it is difficult make headway. I think limbic should also be reported to the ASA and BABCP and BPS should be asked to justify their commitment to Psychological Wellbeing Practitioners (PWPs), the deliverers of low intensity CBT – it looks suspiciously like cronyism, however unintentional.

People Cannot Benefit from a Treatment To Which They Have Not Been Exposed – The Undermining of IAPT

The Improving Access to Psychological Therapies (IAPT) Service does not assess treatment fidelity. Thus, there can be no certainty that clients receive an evidence-based treatment treatment.  IAPT therapies are not EBTs. Despite this, the major funder of IAPT training days SilverCloud, claims on its’ website ‘up to a 70% real-world recovery’ using its computer assisted products, for all common disorders except PTSD and OCD!  The Advertising Standards Authority need to look at this, the ASA has a complaints form that can be completed online. SilverCloud’s UK address is Suite 1350, Kemp House, 152 City Road, London, EC1V 2NX., My own study of 90 IAPT cases suggests just a 10% recovery rate, Scott (2018)

IAPT have produced no evidence that its’ therapists using SilverCloud make any added difference to their clients over and above that of those who didn’t use it. see SilverClouds Space for Depression programme   NICE Guidance ‘Space from depression for treating adults with depression’ Medtech innovation briefing published May 7th 2020. Strangely the NICE IAPT Expert Panel concluded that the case for adoption is ‘partially supported’ despite in the body of report noting lower depression scores, at the end of treatment for the clients of therapists who did not use the computer assisted CBT. An example of spin and conflict of interest.


The SiverCloud website cites 10 references appearing in peer-reviewed journals to support its work.  But none of the studies cited by SilverCloud involve blind independent assessors of outcome using a ‘gold-standard’ diagnostic interview. In the cited review study by Wright et al (2019) Wright JH, Owen JJ, Richards D, et al. Computer-assisted cognitive-behavior therapy for depression: a systematic review and meta-analysis. J Clin Psychiatry. 2019;80(2):18r12188 the third author is employed by SilverCloud.

 ‘Real-world’ recovery represents a change that a client would care about, such as no longer suffering from the disorder that they were suffering from before treatment or a return to best functioning. In a footnote SilverCloud defines recovery as ‘Moving from clinical caseness to non-caseness, i.e. lowering the score on PHQ-9 and GAD-7 from above the clinical threshold to below the threshold’. Such changes are meaningless to clients they are not ‘real-world’.

Here is what one client told  me:

‘I found Silvercloud ineffective, generic and not tailored to my personal situation. It wasn’t engaging or helpful and as such I didn’t engage with the website very much. Consequently, the following weekly call with the IAPT therapist  were sometimes made difficult by the fact I hadn’t completed the same questionnaire as the week before or read through articles. I wanted to talk about my situation, my feelings and find out why I was feeling the way I was, but I felt I was just being led back to using the online SilverCloud resource.

‘It was in 2017 that my doctor suggested I try SilverCloud online CBT with telephone support and in September 2017, I started speaking to another IAPT counsellor. He seemed to be a very nice man. After a few weekly calls, he stated that he didn’t believe I was depressed and so he changed the original Silvercloud course I had started and reset it back to a new series of 6 sessions. The weekly calls lasted between 20 minutes to an hour depending on what we discussed, but always concluded with him asking me to log onto SilverCloud and work my way through the programme before our next call. After the requisite 6 sessions finished in February 2018, that was it! No answers, no tools to help me cope, just signed off, discharged, but told I had 12 month access to SilverCloud. I haven’t used the resource since’.

In general the claims of clinicians and supervisors with regards to treatment fidelity do not match those of independent blind-raters [ Waltman et al (2017)], there are vested interests at play.

The author knows of no study of low intensity CBT (guided self-help, group psychoeducation, computer assisted CBT) that has assessed treatment fidelity. Usage of a manual does not guarantee treatment fidelity. Approx. three quarters of IAPT clients receive low intensity intervention on entry to the Service [Davis et al (2020)].].

IAPT’s approach ostensibly depends on the results of randomised controlled trials of CBT, but a study of remission rates in CBT for anxiety disorders (including OCD and PTSD) Levy, Bryan and Tolin (2021) showed that in half the studies (8 out of 17) there was a high risk of bias because of a failure to address treatment fidelity. Further in 7 of the 17 studies there was a high risk of bias because of the failure to use blind assessors. [A re-view of psychotherapy trial reports published in 6 top psychiatry journals in 2017 and 2018 revealed that only 59% of the included trials reported adequate blinding of outcome assessors Mataix-Cols et al (2021)].].Thus, the research base that IAPT draws upon is far from rock solid.  The remission rate in rcts for anxiety disorders is approx. 50% [ Springer et al (2018)]and this is the ‘gold standard’. But IAPT claims comparable results despite a total disregard for blinding and treatment fidelity! The faked goods ought perhaps to be reported to Trading Standards as well as ASA, in lieu of any interest in the matter from the British Psychological Society (BPS) or the British Association for Behavioural and Cognitive Psychotherapy (BABCP)!

The real story of SilverCloud is that it provides morsels of CBT when what is really needed is a proper meal. It is insulting to clients to in effect say ‘let’s see how you get on with morsels and then we will see about a proper meal’.

It’s A Myth That The Improving Access to Psychological Therapies (IAPT) Service Pays for Itself

IAPT has flourished over the last decade by proclaiming that it pays for itself [see Layard and Clark’s book Thrive  (2014)]. It has been music to the ears of politicians, NHS England and Clinical Commissioning Groups  but none, including the National Audit Office, has bothered to question it. Despite the £1bn price tag this year, see footnote 1. Anyone with the temerity to raise doubts, risks being accused of lacking a commitment to mental health, a pre-requisite of being considered progressive, whatever one’s political hue. 


When will the funding and professional bodies such as the British Psychological Society (BPS) and British Association for Behavioural and Cognitive Psychotherapy (BABCP) see that the ‘Emperor Has No Clothes’? IAPT claims the service pays for itself by getting people off unemployment benefit (16.8% of IAPT clients) Davis et al (2020)  and/or long term sick or disabled benefit (6.9% of IAPT clients).   It is therefore a change in the employment status of minority of IAPT clients that may justify the belief that the service pays for itself. But further elaboration of this population shows that the proportion of clients who could make an economic difference is smaller still. Further when the psychological mechanism by which a change of occupational status may operate is considered, it is improbable that the service pays for itself.  

 IAPT could in principle get 20-25% of clients off benefits. Assuming the target clientele this year is 20%, i.e 0.3 million people, how would the service pay for itself?  Well 40% of IAPT clients do not attend their 1st treatment appointment, so only 0.18 million will be exposed to an IAPT treatment therapist. Of these 42% attend just one treatment appointment, thus 0.1044 million have exposure  to IAPTs treatments and are in the categories of unemployed or long term sick, and potentially might have their employment status changed by the Service i.e 104,440. Those undergoing IAPT treatment ( defined by the Service as attending 2 or more treatment sessions) have an average of 8 treatment sessions in 2018-2019 Saunders et al (2020) but the unemployed and those on long term sickness benefit are less likely to attend a treatment session, Davis et al (2020), as are those who have been referred previously. Thus one might expect this 104,440 to attend a mean of 6 sessions and treatment typically spans 12 weeks according to Saunders et al (2020) . But the population who may return to employment is smaller still because of the following considerations:

  1. There will be a sub-population of the ‘unemployed’ whose unemployment is  related to a work related negative life event, e.g now being physically unable to do the manual work they were employed to do or maltreatment at work. It is difficult to see how 6 sessions of psychological therapy  delivered over 12 weeks would change the diagnostic status of this sub population. There is absence of evidence that such a dosage of psychological therapy can change the employment status of this sub-population. If the sub-population of clients for whom work has been an iatrogenic factor in their debility, are excluded from the analysis, then the population that IAPT’s ministrations could conceivably address is much less than 100,000.
  2.  There will be a further ‘sub-population’ of the unemployed for whom work within their training is simply not available e.g a redundant fisherman. IAPT does not have the resources to conjure up new opportunities, albeit it might direct a client towards re-training.  

Thus the range of action of IAPT with regards to employment status is very limited and even more so when one considers by what mechanism could the typical 6 sessions change employment status over the 12 week span? To return a person to occupational functioning means addressing three key areas a) persistence – the ability to persist with a task b) pace – the ability to complete a task in a timely manner and c) adaptation – the ability to handle the inevitable hassles of the workplace. There is no evidence that IAPT specifically targets these difficulties or has provided training in tackling them. Neither has it been demonstrated that 6 sessions of psychological therapy can resolve such difficulties in 12 weeks and even less evidence as to whether such treatment is enduring.

IAPT lacks the potency to make a real world difference to the unemployed and those on long term sick. Layard and Clark (2014) muddy the distinction between the power of evidence-based psychological therapies and the power of their offspring, IAPT. It can be objected that IAPT pays for itself by increasing the productivity of those already employed, rather than by changing occupational status. But there is no evidence that it does so anymore than the pre-IAPT counselling services.

IAPT’s claim that it changes the employment status of its’ clients is akin to a Dickensian Government’s claim that Workhouses resolve employment issues.

Notice Served On IAPT’s Claim

of a 50% recovery rate. The Editors of Lancet Psychiatry S2215-0366(21)00123-1 have challenged researchers to demonstrate that an acclaimed intervention makes a difference that service users would recognise. Thus making the consumer of mental health services centre stage rather than a change in score on a test. In addition researchers are asked to justify their primary outcome measure. In interpreting test results the Editors insist that  author’s must clarify what a change of X would mean to a service user as opposed to a change of Y. A recently published paper in the Journal, using IAPT data, S2215-0366(21)00083-3 would probably not have been published, if it had not been accepted just before the new guidance was implemented. If other Journal editors follow suit, IAPT’s wings will have been clipped over the claims of IAPT and its’ fellow travellers, such as the British Psychological Society (BPS) and the British Association of Behavioural and Cognitive Therapies (BABCP).  There has been a dereliction of duty by BPS and BABCP.


In this connection I have had the following correspondence with the Lancet Psychiatry  Editors:

My letter

When A Difference Makes No Difference

In June this year the Lancet published guidance [Boyce et al (2021)] for mental health researchers to ensure that the primary outcome measure employed in a study needs to be meaningful. Researchers were asked to a) justify their choice of an outcome measure and b) specify what a change of X or Y on a measure would mean for a service user. Contemporaneously, Lancet Psychiatry published a study by Barkham et al (2021) that made no attempt to address the Editor’s expressed concerns.

Barkham et al (2021) chose to adopt the Improving Access to Psychological Therapies (IAPT) primary outcome measures the PHQ-9 [Kroenke et al (2001)] and GAD-7 [Spitzer et al (2006)], without any discussion. There is no comment that these are self-report measures, subject to demand characteristics and that changes are impossible to interpret without comparison to an active placebo treatment.

The Barkham et al (2021) study involved comparison of person-centred counselling and cognitive behaviour therapy (cbt) in a high intensity therapy service delivered by IAPT. Curiously patients were screened for the study using the Clinician Interview Schedule Revised but neither this nor any standardised diagnostic interview was used as an outcome measure. Why such apparent blindness? The answer is apparent reading the declaration of conflicts of interest, the authors are either devotees of person-centred counselling or have links with IAPT. Their take home message is that person centred counselling might be better than CBT for depressed patients. But there is no attempt to address the question of what proportion of patients lost their diagnosis status and for how long, as determined by an independent blind clinical assessment using a standardised interview. Service-users interests are ill-served by this type of study which additionally ignored data that suggest the recovery rate in IAPT is just 10% [Scott (2018)].

August 13th 2021


Thank you for your letter to The Lancet Psychiatry. We are pleased to see that our initiative re primary outcome reporting has been noticed.  We are applying this now but did not apply it retrospectively to papers accepted before publication. The Barkham et al paper was published online on 14 May, six weeks after the Comment, but was accepted and edited before our new policy was in place. 

For Correspondence, our information for authors states: Letters written in response to previous content published in The Lancet Psychiatry must reach us within 4 weeks of publication of the original item.  We do extend this to after the original item has been published in an issue but I’m afraid that your letter is still outside the window for the Barkham et al paper, so we have decided not to publish it.

Although this decision has not been a positive one, I thank you for your interest in the journal.

Yours sincerely,

Joan Marsh
