I am getting sick of swine flu, aren’t you? So let’s move on to other topics.
How about psychiatry? And lolcats?
A reader sent a recent paper my way by Timo Giesbrecht, Steven Jay Lynn, Harald Merckelbach, and Scott Lilienfeld, in the journal Psychological Bulletin, with the title “Cognitive Processes in Dissociation: An Analysis of Core Theoretical Assumptions.” This paper makes me have to throw my glove down in disgust and, what is more extreme, fire up my Photoshop software.

Steven Jay Lynn, Timo Geisbrecht, Scott Lilienfeld, Harald Merckelbach, and (below, along for the ride) Richard (the Monocle) McNally
Yes indeed, time for the DSM V Shadow Team to roll into action! We can add to ill informed attacks on the PTSD diagnosis this so-called “analysis” that purports to call into question the validity of the dissociative disorders diagnoses, a misguided view that permeates varying ranks of pharma cheerleaders (no drugs approved for those disorders, nope! therefore doesn’t exist) and psychologists trying to get alleged perps off the hook in court via confusing arguments about memory and the like (yes indeed, doubt is their product, and a profitable one too).
I also felt guilty before for saying that the Dutch shouldn’t be allowed to publish in scientific journals but no more. Nope. No way. But I guess we can’t blame it all on the Dutch since one of the authors (Lilienfeld) was from my very own Emory University here in Atlanta, GA, but hey we’ve got our own problems (as those of you who haven’t spent the last year locked in your bathroom might know about). But Scott has his own blog (cool!) with Psychology Today, and his profile picture makes him look like one serious dude, and, well…Anyhoo, these guys are all psychologists, and psychologists tend to spend most of their careers performing experiments on their own students (kind of creepy, huh, for instance Merckelbach admitted that one of his “experiments” involved performing a “surprise” on his students, to0 bad they couldn’t let loose the VA research compliance officers on him now) and they don’t get out much, so they are always glad to get a little attention, and they have found that being “controversial” is the best way to get some attention, and maybe cash on the side as expert witnesses testifying on behalf of ALLEGED perpetrators of childhood sexual abuse.
Anyhoo the premise of the paper is (the short version) that dissociation is bullshit, made up by flakey clinicians, and we are smarter than you guys.
OK, here is their “formal” position. Fantasy proneness, absorption, and what they call “cognitive failure”, are correlated with dissociation, and they don’t think that dissociation is related to psychological trauma, so dissociation is not something real, but something made up by impressionable people. OK on to the “science”.
First off, their argument that dissociation is not a pathological construct, but is merely a variant of normal experience, namely the capacity for absorption, which is accepted as a “normal” personality trait. Disclaimer: I score off the charts on both absorption and hypnotizability scales. In fact, I can induce myself into an autohypnotic trance at will. [Do what you will with that evil Dutch psychologists-- Hah!
Absorption is measured with the Tellegen Absorption Scale (TAS). Score on the TAS has only a weak correlation with dissociation, as measured by scales like the Dissociative Experiences Scale (DES), as described in my edited book Trauma, Memory and Dissociation, (I thought people got tired of hashing over these issues a decade ago!). And finding correlations with scales like the Dissociative Experiences Scale (DES) which everyone acknowledges is full of absorption items, is meaningless.They claimed that they did this comprehensive medline review on dissociation scales, but they didn't include our Clinician Administered Dissociative States Scale (CADSS), whose psychometric properties have been published, and which clearly shows an increase in dissociative symptoms in traumatized populations, in contradistictinction to their proposition that there is no evidence for an association between trauma and dissociation.
Here are some items from the Tellegen Absorption Scale
True False 01. Sometimes I feel and experience things as I did when I was a child
True False 02. I can be greatly moved by eloquent or poetic language.
True False 03. While watching a movie, a TV. show, or a play, I may become so involved that I forget about myself and my surroundings and experience the story as if I were taking part in it.
I mean those are all cool things, aren't they?
They use a lot of creepy techniques in this paper, like citing something to support their statements when the actual paper doesn't support their statement (I hate that!), or going through a long string of description of studies, and then making a conclusion that isn't supported by the studies they reviewed (tricking the lazy people who don't want to read all those original papers). Or leaving out papers that don't support their ideas. Or doing the old let's pick the test that supports our conclusion and discount the rest.
As an example of the latter, they are only too happy to cite a review by John Kihlstrom, a Professor of Psychology from UC Berkeley, that states there is only weak evidence for a relationship between trauma and dissociation (I had to pay twenty bucks to get that review. Damn! But since the Drug News and Health Safety Blog has declared itself free of bourgois capitalism here it is for you for free). Kihlstrom did mention the CADSS but dismissed it as measuring depersonalization and derealization and not the "core" items of amnesia. How amnesia was determined to be the "core" I'm not sure unless you are focused on gossipy arguments with psychotherapists from California about recovered memory to the exclusion of everything else. Here are a few amnesia items from the CADSS for you Professor:
Have there been things which have happened during this interview that now you can’t account for?
Do you have gaps in your memory?
Anyhoo Giesbrecht et al. completely ignore a paper I wrote with Kihlstrom in 2000 showing NO correlation between dissociation, as measured with either the DES or the CADSS, and false recall of critical lures on the Deese paradigm in sexually abused women with PTSD who have high levels of dissociation. They talk about a couple of other papers that used the Deese paradigm (also negative studies) but then critique the paradigm as a good measure of false memory. Would they have done so if these studies fit their pre conceived ideas? I doubt it, probably the complete opposite.
They also make several loaded suggestions that dissociation is related to suggestibility, but the first paper I came across with a random google search on suggestibility using the measure I am familiar with, the Gudjonsson Scale (which they also cite) showed no association.After their review of the corpus of literature which hardly supports what they are about to conclude, they go on to state that: "a combination of fantasy proneness, interrogative suggestibility, and the susceptibility to cognitive failures may undermine the accuracy of retrospective reports of traumatic experiences, resulting in overestimates of childhood trauma rates (i.e., false positives)."
In other words, they are making it up in their mind, they got their facts wrong, or someone else suggested it to them. And the "cognitve failures"? A quick look at their scale for measuring such shows that several of the items (e.g. "Do you find you forget why you went from one part of the house to the other?")are commonly seen in dissociative patients. They go on to say that:
With respect to the relation between self-reported traumatic experiences and dissociation, it is noteworthy that widely used self-report instruments such as the Childhood Trauma Questionnaire contain broadly formulated trauma items that inquire about beliefs or opinions. These items may encourage overreporting of trauma, especially among individuals high on fantasy proneness.
What the hell is that supposed to mean? I "believe" that I got punched out by my Dad and that is only my opinion? Like maybe my Dad sez it never happened? One cannot help but see the parallel between the Giesbrecht gang telling mental health patients that they are day dreaming or making stuff up and abusive parents saying it didn't happen that way back then.

Say it ain't so!
You can view our (similar) Early Trauma Inventory here and decide for yourself whether the items are “broadly formulated” and “inquire about belief or opinions.”
As for dissociation being related to “fantasy proneness” (whatever that is) the research referred to was… you guessed it! Performed by the authors themselves…

I wonder if Dr. McNally is recruiting for any of his studies?
… namely the Creative Experiences Questionnaire (CEQ), created by Dr. Merckelbach himself. They go on to state that “few investigations
have controlled for general distress and psychopathology, or for scores on the personality dimension of openness to experience, which is moderately associated with both dissociative tendencies (Kihlstrom, Glisky, & Angiulo, 1994) and with crystallized intelligence (DeYoung, Peterson, & Higgins, 2005).” However a perusal of the Kihlstrom et al 1994 paper showed no mention of a relationship between dissociation and openess to experience, because quite frankly, there is none. There they write:
Many, if not most, fantasy-prone individuals are very well adjusted… There appears to be no study testing the hypothesis (Lynn, Rhue & Green, 1988) that fantasizers are specifically at risk for dissociative psychopathology.
Thanks for the clean bill of health, John. And I might add that what Giesbrecht, Lynn, et al cite as “evidence” of their ideas in fact cites them in turn as “untested hypotheses”. Remarkable!
Anyhoo our jolly band goes on to state:
Levin, Sirof, Simeon, and Guralnick (2004) and Huntjens et al. (2006) reported elevated levels of fantasy proneness in patients with DPD and DID as compared with those of nonsymptomatic participants.
However if we actually read the paper of Levin et al 2004, you will see that they write the following: “It should be noted that total scores for the [depersonalization disorder] DPD group were well below threshold for this dimension, with scores falling at the lowest end of the criterion for medium fantasy proneness (a score between 14 and 36). Contrary to our prediction, depersonalized subjects did not report significantly higher absorption levels on the TAS than controls.” Huntjens et al 2005 found that DID patients had a score of 10 v 7 on Merckelbach’s measure of fantasy proneness, the CEQ, which is hardly a huge difference. Also if you look at the actual items on the CEQ some of them are really dissociation, like “I sometimes feel out of my body” (that’s depersonalization… Doi!). Back to our friends:
The fact that individuals who dissociate frequently engage in fantasizing may have profound consequences for understanding the origins of dissociative experiences. Notably, imaginative tendencies may compromise the validity of self-report questionnaires that measure trauma on a retrospective basis. Fantasy proneness could affect responses to such questionnaires in two ways. First, fantasizers may confuse imagined events with factual autobiographical memories. The failure to differentiate imagined from real memories is termed a reality monitoring error… Second, fantasy-prone individuals may adopt a more liberal response criterion for reporting an experience as genuine (i.e., a “real” memory), thus exhibiting a positive response bias, or in more extreme cases, a tendency to confabulate…
In other words, dissociative patients are fantasizers who imagined they were abused. That reminds me of Paul McHugh MD, Professor Emeritus of Psychiatry at Johns Hopkins School of Medicine, whining at one of the American Psychiatric Association Meetings at a “debate” on false memory, while presenting one of “case reports”, “This woman’s diary showed that she wanted to believe she had been abused to make her understand why she was depressed. But how could this woman have been sexually abused by her father? He was a very prominent person in Baltimore.” As if that means anything. I don’t know that Paul McHugh ever did any research on the topic or has any other qualifications in the area. I once heard him described as an “evil leprechaun”.

Paul McHugh MD, Professor of Psychiatry
Just so Dr. McHugh doesn’t feel lonely, here are some leprechaun friends:

No sexual abuse here! Only fantasy!
Anyhoo our jolly band next discuss a study by Dr. Merckelbach, in which a correlation between dissociation measured with the DES and comission errors (reporting seeing a picture not previously seen) “disappeared” after “controlling statistically for fantasy proneness” from which they concluded:
This study provides further support for the idea that individuals with a high frequency of dissociative experiences more readily endorse descriptions of events of differing affective valence due to a positive response bias linked to fantasy proneness.
Wow. They go on to state “there is no good evidence for a traumatic etiology of DID or any other dissociative disorder”. And the citations for this incredible fact? Well more citations of papers written by themselves of course! Papers that were opinion pieces. Oh, and this review by John Kihlstrom of course, where they refer us to look at “Page 14″. I had some trouble with that one, since his paper started on page 227! But no matter, lest we be seen as too picky lets examine what Kihlstrom actually said in his review discussing a study be Williams et al in 1994 in which they showed that almost half of people could not remember severe childhood abuse documented in the ER when approached years later:
Although Williams did have satisfactory independent corroboration of the traumatic events, she failed to distinguish between traumatic repression and ordinary time-dependent forgetting, infantile and childhood amnesia, or even a simple reluctance to report embarrassing memories to a stranger.
What?? Anyhoo he goes on:
In view of this body of evidence, theories that attempt to describe the psychological or biological processes by which trauma induces amnesia (Freyd 1996, Metcalfe & Jacobs 1998, Nadel & Jacobs 1998, van der Kolk 1994) appear to be rendered moot by the apparent fact that trauma-induced psychogenic amnesia occurs rarely, if at all.
Indeed. We reported over a decade ago that over half of traumatized Vietnam veterans with PTSD have dissociative amnesia. But hey, I wouldn’t let data stand in the way of anyone’s opinions. Lolcat has her own opinions.

- Dr. B, John Kihlstrom, and Lolcat debate trauma & memory.
