and the added value of low intensity IAPT is?

compared to how people would have got on anyway if not referred to IAPT (in economist terms the appropriate counterfactual), the ‘added value’ has not been demonstrated. Yet most people receive a low intensity intervention such as computerised CBT, guided self help or groupwork.

I could find no independent outcome assessors involved in the randomised controlled trials of low intensity interventions that the NICE guidance largely relies on. Instead reliance has been placed on IAPT’s marking and marketing of its’ own homework.

In a review of randomised controlled trials published in 4 medical journals Kahan, Rehal and Cro (2015) only a quarter (26%) involved blinded outcome assessment. These authors write ‘Previous reviews have found that unblinded outcome assessment can lead to estimates of treatment
effect that are exaggerated between 27% and 68%’ see link below:

But the position appears worse when it comes to psychological therapies with no reliable rcts for low intensity interventions, and with regards to high intensity interventions the few blind outcome assesments are clustered around depression, the anxiety disorders and PTSD. Since the millenium there has been a drift away from the use of outcome assessors, this makes research cheaper, it is much easier to massage statistics to give a positive hue, the originators of an intervention and those with a vested interest are given a free hand.

Researchers on IAPT [seee Bower et al (2013)] play fast and loose with Cochrane risk of bias tool, see link below:

and jettison the need for independent blind assessment implicit in the tool on the spurious grounds that ‘most outcomes are self-reported’ see link below:

Looked at from the perspective of independent outcome assessment the claims for low intensity interventions look spurious and the evidence base for high intensity interventions is more circumscribed than BABCP conferences or IAPT would suggest.

The IAPT Manual published last year recommends extension of the service to irritable bowel syndrome, chronic fatigue syndrome, chronic pain and medically unexplained symptoms not otherwise specified but makes no mention at all of the need for independent blind assessment of outcome, instead it suggests simply what self-report measures should be administered. See link below:

Yet another marketing opportunity, when we need real world answers, how many people said to an impartial observer that they were back to their usual selves after the intervention? how long did this last?

Sham Psychological Therapy Rules

Bernard felt ‘ten times worse’ after his first session of IAPT, Group CBT. He didn’t return for further sessions. IAPT advised him to seek individual therapy via his GP, which he did but none was ever forthcoming. When I saw him it was three years after his industrial accident that rendered him unable to work, his depression had continued unabated. The GP records simply recorded that he did not attend 3 sessions and so was discharged, the implication was that he was at fault!

What had actually happened is that following an IAPT telephone assessment he was invited to therapy at a local centre. On arrival he and others were given a questionnaire to complete. He and about 15 others were then ushered into a room, but there were not enough chairs so some stood. The group leader began asking each of them in turn what their problem was. Bernard protested ‘ I can’t tell my problems in front of all these’, he said that he could see that the young men in the group were agitated and one ‘girl’ on the verge of tears. ‘it was more like a lecture with flipchart and screen’.

The IAPT treatment bears no relationship at all to the group CBT detailed, in my book ‘Simply Effective Group CBT’ published a decade ago by London: Routledge or to what I am trying to promote as Co-chair of the BABCP Group CBT Special Interest Group. A year ago the IAPT Manual was published but none of it confers any protection for a client suffering the same fate. The worry is that in the interest of a numbers game more people will suffer Bernard’s fate.How long is the cover up going to go on!

IAPT Hoodwinks NHS England

by alleging compliance with NICE recommended evidence-based psychological treatments. But, NICE bases its’ recommendations, largely, on randomised controlled trials conducted on specific disorders, with different protocols for different disorders. It is impossible to implement NICE guidance without reliable diagnosis, but IAPT have never claimed that its’ clinicians make a diagnosis!

Even the notion of a utilising a ‘provisional diagnosis’ was jettisoned in last years IAPT Manual, (see link below) in favour of a ‘problem descriptor’:

On the basis of a client’s ‘problem descriptor’ the IAPT Manual requires its’ therapists to specify an ICD-10 [International Classification of Diseases 10th edition, World Health Organisation] code for a disorder, which would allegedly indicate the appropriate protocol. However there are 99 codes for Mental and Behavioural Disorders in ICD-10, there is no bridge between a ‘problem descriptor’ and a disorder. If such a leap were possible ICD-10 ( the World Health Organisation) would not have bothered to specify diagnostic criteria for the 99 conditions! Within IAPT clinicians come up with a ‘problem descriptor’ in just 2/3rds of cases, [ Clark et al (2018)] see link below:

and usually following a 20-30 minute telephone conversation, it is therefore a matter of ‘plucking a code’ from thin air for administrative purposes,

if the clinician can remember this particular ticking the box exercise.

The Clark et al (2018) study was published in the Lancet, and funded by the Wellcome Trust, and headed ‘Transparency about the outcomes of mental health services (IAPT approach): an analysis of public data’ and states:

‘Role of the funding source
The funder of the study had no role in study design, data
collection, data analysis, data interpretation, or writing of
the report. The corresponding author had full access to
all the data in the study and had final responsibility for
the decision to submit for publication’.

But there is no mention that the lead author is the leading light in IAPT, and that with one of the other authors, Lord Layard, they were the architects of IAPT. Where is the ‘transparency’ in this? In fairness in this paper they do state that a limitation of their paper is that their data is dependent entirely on client self report, but a conflict of interest stops them going on to say, that there needs to be an independent audit of IAPT, in which the diagnostic status of clients is assessed before and after treatment and at follow up.

My own independent analysis of 90 IAPT clients suggests that, contrary to IAPTs claims of a 50% recovery, just the tip of the iceberg loose their diagnostic status diagnostic status, see link below:

NHS England needs to clearly establish whether or not the public is ill served by IAPT and not to rely on the claims of those with a vested interest in providing the Service.
