Continuing with the Methods section Search strategy They are vague about what words were used for their search strategy. I think, if you were trying to determine the prevalence of exaggeration of symptoms in independent medical exams, there are problems with the words reported as being chosen...

I'm also disappointed to see Chris Armstrong @MelbME on this list. That's not because I think Chris is not good at his job, to the absolute contrary, I would far rather he was using his time researching ME/CFS, and supporting his team to research ME/CFS. That is the way he can contribute most...

I have quite a lot of concerns about that guideline committee - probably not helped by the fact that I tried really hard to be on it. One is that Dr Sarah Knight is on it - we've talked about her in the context of her being the one in charge of the psychological assessment for one of Chris...

Ha, frog slime could be Gwyneth's signature therapy.

I've made a thread to discuss criteria for determining if someone is a malingerer, including the Slick, Sherman, and Iverson criteria that was used by a lot of the studies included in the review. Diagnostic criteria for malingering The authors themselves, in a 2020 review of their 1999 criteria...

I've got to stop. That 2020 paper is incredibly long and I haven't got to the end of it yet. The revised version still seems to be focussed on assessing the feigning of cognitive capacity, in order to, for example, avoid being judged mentally capable in a criminal trial. Here's a box with some...

There's a whole lot more on Presentation Validity Tests. To me, it looks like people arguing about how many angels dance on the head of a pin e.g. here they are trying to work out how many tests have to be failed in order to be a malingerer - or is it the ratio of the number of tests? And...

On Presentation Validity Tests 'the original MND criteria' are, more or less, what has been used in much of the malingering literature. It was very vague and the authors admit this.. It's a bit laughable. 'Experimental malingerers' So they give healthy people a cognitive test and ask...

On compelling inconsistencies A lot of the examples of inconsistencies given could easily be explained by a medical condition that fluctuates in severity or affects only specific tasks. Someone might come across as vague and evasive about a prior mental health diagnoses if they don't agree with...

After all that, I'm still not understanding how malingering is determined. It seems pretty circular and subject to the bias of the assessor. All of the assessments and categories seem to be just adding a veneer of 'sciencey-ness' to what boils down to the feeling of the assessor. I get the...

This is from the 2020 paper. The authors praise their 1999 work: It seems that the criteria were criticised for being too biased to military and forensic settings, and not so appropriate for assessing children. Also, that they were focussed on cognitive dysfunction, but also needed to assess...

Multidimensional Malingering Criteria for Neuropsychological Assessment: A 20-Year Update of the Malingered Neuropsychological Dysfunction Criteria, 2020, Sherman, Slick and Iversen The same authors as the 1999 diagnostic criteria appear to have made an update. Those are astonishing claims...

Diagnostic criteria for assessing malingering are used in insurance medicine. A recent review found that 61% of the studies found assessing the percentages of people judged to be malingerers used this one: Diagnostic criteria for malingered neurocognitive dysfunction: proposed standards for...

Methods They registered a protocol. But then, some time after that, they decided how they would analyse the data. They say it was before they looked at their data. The lack of a pre-trial analysis plan increases the likelihood that they cherry-picked the analysis approach to gives them the...

Introduction In other words, 'independent medical evaluations of the same individual are coming up with quite different answers. It's not a problem with the evaluation process. The problem is that some doctors are failing to recognise that many of the people making claims have reasons other...

The beauty of using Cochrane as the messenger of an ideology that is useful to the insurance industry (at least in the short term) is that it doesn't matter what consultant you get to do your disability evaluation, in Switzerland or anywhere. Most can be relied on to have absorbed the Larun et...

I think our members from Switzerland should be aware of Regina Kunz. According to the affiliation reported on a recent study she co-authored with a finding that helps the insurance industry dismiss people's claims of having a debilitating health condition, Kunz is based in Basel, Switzerland.
