How to hijack the whole notion of biomedical and pervert it to whatever ends suits one's desires.
All they are going to do is look for superficial, highly selective subjective correlates, and make sure none of it properly tests for causation, and claim that proves the psychosomatic interpretation is correct.
David Tuller wrote about these Dutch research funding awards in his last two publications. I quote from one of his articles:How to hijack the whole notion of biomedical and pervert it to whatever ends suits one's desires.

David Tuller wrote about these Dutch research funding awards in his last two publications. I quote from one of his articles:
"Last July, ZonMw posted an update about an 'adjustment' to the process of evaluating proposals. According to the update, key patient representatives would not participate in decision-making about funding recipients because of their perceived conflicts of interest."
Conflicts of interest!! I'm truly stunned by that statement. Of course, patients have a HUGE self-interest in this process, and they should have, and that should be respected. It is they we are talking about. It is they whose lives are on the line. It is they who have first-hand knowledge of this disease. It is they who are (or should be) at the center of this research, not the researchers themselves. In my opinion, it is certain researchers who have the huge conflicts of interest here which they then project unto the patients who are merely speaking truth to power and fighting for their very lives. It is certain researchers trying to hold on to their territory who have the conflicts of interest.
To me, the above quote epitomizes the huge power imbalance between these researchers and very knowledgeable patients who must be kept in their place. The researchers' ideas about this disease must come out on top, no matter how many years of lived patient experience contradict those ideas. That quoted statement to me smacks of a power play having taken place. Perhaps I am wrong, but right now, that is how it seems to me.
Correct. The double standard is appalling.Conflicts of interest!! I'm truly stunned by that statement. Of course, patients have a HUGE self-interest in this process

"'For almost ten years now, criteria for diagnosing ME/CFS have also been included in the Lifelines data collection,' says Rosmalen. 'So we have a lot of biomedical data and biomaterials from patients with ME/CFS. We have also found people who were found to have ME/CFS but who had not yet been diagnosed."
Fatigue (CDC)
The Centers for Disease Control and Prevention (CDC) symptom inventory for chronic fatigue syndrome (CFS or ME) is aimed to assess whether a person meets the CDC diagnostic criteria for (CFS)1) (section: diseases & symptoms).
Note that Lifelines also assesses (chronic) fatigue using the CIS and PROMIS instruments plus some general questions. An CFS diagnostic score according to the CDC has been developed and is available for use.
Background
Lifelines repeatedly assessed the presence of CFS/ME by self-report. However, recent studies indicate that this method misses ~90% of the CFS diagnoses2). The CDC symptom survey improves the identification of participants that meet the diagnostic criteria for CFS/ME by assessing the presence of individual symptoms rather than the disease itself.
The CDC symptom survey was developed in English and translated in Dutch 3).
The CDC symptom survey as used in Lifelines assesses 8 symptoms that are part of the diagnostic criteria for CSF, plus a question regarding depressive feelings in the last 6 months to increase the diagnostic value.
To assess fatigue, the core symptom of CFS, an additional question was asked in conjuction to the CDC (see here).
Validation
The validation of the CDC symptom survey is described here4)
Researchers from the University Medical Center Groningen developed the Chronic Fatigue Syndrome (CFS) diagnostic score for adult participants using the Fatigue (CDC) variables from 2A Questionnaire 2 and 3A Questionnaire 1. (sections: Diseases & symptoms (Fatigue (CDC)) and secondary & linked variables).
The CFS diagnostic score can be requested in the Lifelines catalogue or by mail (data@lifelines.nl).
Calculation of CFS diagnostic score
To identify participants with a positive Chronic Fatigue Syndrome (CFS) diagnostic score, the 1994 Centers for Disease Control and Prevention (CDC) criteria are taken into consideration. More specifically, participants have to meet three specific criteria in order to receive the CFS diagnosic score. In other words, if all criteria are met the participant receives a positive diagnostic score and when at least one of the criteria is zero the participant receives a negative CFS diagnostic score. If all three criteria are missing, the CFS diagnostic score is also missing. Below the three criteria are highlighted including details on the included statements in the calculation.
Lifelines participants were asked the following questions about their experiences with fatigue (section: Diseases & symptoms).
Note that fatigue is also assessed within Lifelines using the PROMIS and CIS instruments.
Chronic fatigue syndrome is assessed using the CDC instrument. The FATIGUE1-3 variables were formulated as an addition to the CDC.
secondary_linked_variables [Lifelines Wiki]Secondary & linked variables
This section contains two types of data:
The following secondary variables are available:
- Secondary variables, i.e. variables derived (typically by coding or calculation) from primary variables collected directly from Lifelines participants.
- Linked variables, i.e. that were not collected by Lifelines but are obtained from another data source and linked to Lifelines participants (typically via postal codes).
- Chronic fatigue syndrome (CFS) diagnosis according to the Centers for Disease Control and Prevention (CDC)
That checklist is referenced at the bottom, it'sFatigue (CIS)
The Checklist Individual Strength (CIS) is a 20-item fatigue questionnaire developed in Dutch 1) (section: diseases & symptoms). The questionnaire has been translated into multiple languages and is used to set diagnostic criteria for various illnesses, including chronic fatigue syndrome/myalgic encephalomyelitis (ME/CFS).
Note that (chronic) fatigue is also assessed in Lifelines using the CDC and the PROMIS questionnaires, and some general questions.
Scoring
De CIS consists of 20 statements on fatigue-related problems respondents might have experienced in the past 2 weeks. A Likert scoring scheme is used: with each statement respondents have to give a score between 1 and 7, indicating how much the statement applies to them.
A factor analysis indicated 4 components in the 20 questions:
- Subjective fatigue (8 items)
- Concentration (5 items)
- Motivation (4 items)
- Physical activity (3 items)
Lifelines repeatedly assessed the presence of CFS/ME by self-report. However, recent studies indicate that this method misses ~90% of the CFS diagnoses2).
Bwahaa, holy shit, the reference for this weird statement:
is Warren JW, Clauw DJ (2012). Functional somatic syndromes: sensitivities and specificities of self-reports of physician diagnosis. Psychosomatic Medicine 74(9):891-895
This is not subtle.
I'm going to make a cup of tea, as I don't want to spam this page with my ongoing jawdrop.
I'm not sure what you mean by that? We only know what was mentioned here in the thread.
And to summarize (correct me if I'm wrong @Grigor and @Solstice ) this is the main line of the situation:
Two consortiums got awarded grants from the first round of Dutch Biomedical Research for ME/CFS funding .
Consortium B (NMCB) contains 6 research projects which will pull their participants from an ME/CFS biobank that AFAIK has used good research criteria for ME/CFS, so the participant pool is acceptable. It has also trusted patient representatives collaborating like Lou Corsius. I don't know much about them, but in basics it seems ok.
Consortium A (ME/CFS Lines) contains 4 research projects which will pull their participants from the Lifelines databank. They will collaborate with patient representatives from the ME/CVS Stichting only (who will be paid -I'm personally on the fence about that), an ME organisation that doesn't have a good track record in being informed, critical and a good patients advocate. There are two main issues with this consortium:
Important patient organisations like the ME/CVS Vereniging were not involved in preparing for this grant application and they weren't given enough information (though requested) to assess it - the ME/CVS Vereniging is currently running a FOI request to understand how and on which grounds exactly this grant was awarded.
- This project specifically and the Lifelines biobank are headed by Judith Rosmalen, a motor behind treating ME/CFS as psychosomatic/MUS/functional disorder
- There are major questions about the reliability of patient selection from Lifelines. See for example Andy's post here. It seems like they have used more relaxed criteria for prolongued fatigue (CDC94?)* without additional "must have" cardinal features like PEM and cognitive impairment, an added patients that were not diagnosed by a physician, and the chance that their "ME/CFS" patient population is a mixed bag of stuff is considerate. (Personally I would be surprised if Rosmalen has kept a database on strict ME/CFS research criteria given her work.)
The situation gets even more complicated as Rosmalen's ME/CFS Lines databank apparently doesn't hold data for severe patients and will borrow severe patients from the other consortium NMCB for their studies - which causes unrest as well-informed patients don't want their body to be used for research led by Rosmalen. (Plus of course patients are livid at ZonMw for giving millions of the money to a leading figure in the bps movement, so they can lose trust in the whole thing.)
I feel a bit bad for the researchers attached to Lifelines, but on the other hand, if it's true that a "fatigue"/CDC94" patient pool is used, then I have some doubts about how well-informed the researcher is - why risk having all your hard work dismissed for bad participant selection?
*Edited to add: Yes, there are major, major issues with the patient selection for the ME/CFS Lines consortium: self-report, Fukuda, a bps questionnaire and questions on general fatigue.
As I read it there are 2 different biobanks, one of which Rosmalen is involved with which seems to be already in operation and which has questionable diagnostic criteria. The other project funded seems to be using a different biobank, presumably with better selection criteria including PEM.Ok, thanks. So she is involved with the proposed biobank.
