A (very) critical "review" of CBT: mindfulness

In previous posts I told you that I did an inpatient CBT program for depression. I described the activity planning group here and the relaxation classes here. Today I’d like to share my experiences with the mindfulness group.

I doubt that these classes were according to any protocol, so I don’t want to extend my opinion on it to everything that’s called mindfulness. In the beginning of (almost) every class we were told the mindfulness or pleasure rules: Pleasure needs time, needs to be allowed, is individual… and the rest I don’t recall despite all the repetition. After that we had to focus on one sense, seeing, hearing, tasting, touching, and smelling. For example we were given an item in the hand with closed eyes and had to touch it to see how it feels, or we had to walk through the room and focus on the different colors we could see. I hope you get the point.

Now, I think it this *may* be *some* distraction, but it doesn’t really help. The mechanism by which it should help is not clear to me. When I’m feeling well, this would probably be an interesting task, but when I’m not it’s not. When I’m fine I like a lot of little things, an accidental splash of color on my water bottle, packaging foil (the sounds and looks of it), trees (they just look interesting and come in so many different forms), and lots, lots more. But part of depression is loss of pleasure and it doesn’t come back with just seeing things you might otherwise find beautiful or interesting. I can well describe the sensations (the roughness or softness of a material, the temperature of it, etc.) but it doesn’t mean anything. Chocolate tastes different than cardboard, but it is the same feeling. It’s just not nice. It’s effort. In some way I think the focus on what should be nice but isn’t is quite depressing in itself. It is like they try to tell you “but look, the world is nice, you’ve just to focus on that” but it doesn’t feel, look, take, sound nice.

Having a story to tell...

In a TV-documentary I once saw there was a prosecutor who basically said (smiling): “Yeah, I know that he fitted the criteria for insanity, everyone knew, it was so obvious. I didn’t think we’d succeed with our strategy but we had to build this *narrative* that he was sane.” And she seemed to be totally fine with it, she did her job and won, so that’s something to celebrate, isn’t it? Well, I don’t know. While she succeeded in her job, shouldn’t trials be about evidence and justice instead?

In science, I think this is even more complicated because there isn’t necessarily a representative for every side of an argument. While there of course is peer-review (which serves that purpose), peer-reviewers (most of the time) can’t know what is not reported, what is not part of the narrative that the authors tell. They don’t go and dig failed preliminary studies or replications out of the authors’ file-drawers; they don’t search for evidence against the authors claims.

Therefore I think that in research it is even more important that the full story, not just the prettiest element of it is told. However, that is not what we are taught. In 2015 I attended a Summer School for PhD-students. It was very interesting and I learned a lot, however we also were told that we have to tell a story, report the aspects that are most convincing and interesting to tell. While I understand and agree with some parts of that (data can be shown in confusing or less confusing ways) I think that this advice is mostly understood (and probably meant) as “out of the many things you could tell about your study/your data, you’ve to pick the most interesting part and choose the aspects of the data that support it, while ignoring the rest”. I think that this is wrong.

Who's responsible for flawed studies?

In his blog post about case of data-fabrication in which the (alleged) fabricator was not included as an author, Neuroskeptic notes that „Authorship means responsibility“. I agree!!

In this case, the grad student who collected and manipulated the data remained (so far) unnamed, because he is, rightly or not, not listed as an author. But while it should be clear that authors have to take responsibility for what is published under their name, I think that responsibility reaches further.

In any complex study naturally a lot of people are involved. Of course it’s not the fault of the person at Siemens who wrote the scanning sequence if we then go and use it incorrectly and – in my opinion – neither is it the fault of a supervisor if their PhD-student “cleverly” manipulates the data.(1) After all it’s not kindergarten; not everything can be checked.

But it should be (though I know that it not always is) by “surprise” if an aspect of a study turns out to be problematic after publication: You shouldn’t be able to know prior to publication that, say, the statistics are somewhat dubious; papers with fishy statistics shouldn’t be published. However, it might turn out later on that “consistent signals” may just be artifacts produced by the imaging techniques - and the fact that brains need a constant supply of blood. In such cases it would be useful to know which sequence was used and how – exactly - the resulting data were analyzed. To figure that out the people who chose the sequence or did the analyzes should be known – which in the current mess of unregistered studies is much more likely if they are (co-)authors. Of course they also deserve to be on the paper if they had (substantial) work with the study but for them to become important at some point it doesn’t really matter how “scientific” their work was. The purely technical aspects can be just as important: How long did it take before blood was frozen, how (exactly) where the patients immobilized in the scanner, which arm was the blood pressure apparatus on, did the optic cables reliable transfer the signal and how was that made sure, …? One might say, that all these kind of information should be part of the publication but often it isn’t.

Another point is which responsibilities people involved in research have beyond their specific duties. While I generally think that the responsibility doesn’t extent (much) above ones area of expertise, I do think that everyone does have the responsibility not to knowingly do or support unethical stuff – and any unjustified or flawed study is unethical in my opinion. In this sense funding agencies share a great deal of responsibility and, once known, the media are also responsible for reporting scientific misconduct. However, of course it can be difficult to judge which studies are unethical or flawed.

(1) If the data are manipulated “uncleverly” I do however think that the supervisor has some responsibility because he or she should be able to “see” that.

A (very) critical "review" of CBT: activity planning

I have been doing a cognitive behavioral therapy (CBT) program for depression. In yesterdays post I described the relaxation classes we had to do as part of the program. Today I’d like to talk about the “activity planning” group.

The group was based on the notion that actions, feelings and thoughts influence each other. Therefore – we were told – we just had to get doing (pleasurable!) stuff again in order to feel better and have more pleasant thoughts. We were handed a list of over 200 potentially pleasurable activities and had to do one such activity alone and one together with other people for each class. Each such activity furthermore had to be rated on a 1 to 10 rating scale in the dimensions “mood”, “drive” and “ease of mind” before, during and after the respective activity.

While I understand that it is important to get doing stuff – cos otherwise with absence of or low drive you’d just lie in bed and eventually die of thirst (or lack thereof) – I find that it is asked a bit much, that those activities should be perceived as pleasurable. For me, it just made me feel even more like a loser, because I couldn’t get any pleasure out of going for a walk, even though I tried. (“But it’s nice out here… I just have to tell myself… It’s nice… Sun and wind and…. But it sucks so much, why do I have to do this… I don’t have the energy, I’ll never arrive at the other end of the street…. And how do I know if it’s nice, the world is f*cked pretty much. It’s NOT nice. Climate change, and plastic in water, air pollution…. Why do I have to walk here, it’s so exhausting…. And the food we get here is wrapped all in plastic…. Which pollutes the seas….. But the river is NICE…. I’ve to tell myself…… But I don’t want to lie, not to others and not to me…… it’s not nice…. But maybe liars are the better people, at least they make others happy and aren’t such failures….. I hate this.” And so on….).

But what’s more important than that potentially nice activities didn’t seem to work for me is how to group was lead: It was instructed by whichever nurse had duty that day and they seemed to have very different opinions about what constitutes a pleasurable activity (independent of the list). While some accepted everything others had very specific ideas and would even get mad at you if you did an activity which they didn’t find pleasurable, for example tidying up or learning something (as an activity alone) or skyping and chatting or tweeting (as an activity with others). In their mind you had to get a massage or take a bath or color in something as a nice activity alone and an activity with others had to involve more than virtual contact (going to the cinema or a cafe would do). Now, I don’t find tidying up that pleasurable either, but at least something’s done afterwards, i.e. there’s less mess. If I’d get a massage I wouldn’t enjoy it and my place would be just as messy afterwards, so therefore nothing would be gained. Probably I’d feel guilty for spending the money on something I didn’t even enjoy, and like a failure for not enjoying something which should be enjoyed. Therefore I prefer tidying up – it has the better consequences. However, as I said, not everybody shares that opinion and while of course everybody is entitled to theirs I find it unhelpful decry the activities of people who tried their best to do (and enjoy...) them anyways. But of course not every nurse was like that, some didn’t really give a shit (so that the group ended within 5 minutes after everyone had recited their ratings) and others were trying to be helpful and encouraging (e.g. by suggesting in which other situations the said activity could be helpful or how the activity itself could be improved or what could be done instead).

Overall, is it helpful having to be doing a “pleasant” activity? Personally, I don’t think so, because it’s just not pleasurable and not feeling anything nice made me feel bad. *Just* doing some stuff, without any aspiration to finding it pleasurable *might* be helpful: Not eating or not drinking (water ;) ) doesn’t either, nor does not showering or not brushing teeth etc. But, in my opinion, it can be unhelpful to hope for any pleasure doing these things. Because if that’s the point and it’s too far away you might as well just not do it.

A (very) critical "review" of CBT: Progressive Muscle Relaxation

I did an inpatient CBT program for depression (as a patient) and I’d just like to express my opinion about it (because in a lot of ways it sucked … and apparently I’m not well enough to fill out their feedback form, so…). Of course it’s just that, just my personal opinion and just based on personal experiences at one time and at one place. Other people will have different experiences.


The program consisted of relaxation, activity planning, a mindfulness-group, music (and/or art) an “Info-Group” and of course the CBT itself (in a group and individually with a therapist).

In the relaxation group we did Progressive Muscle Relaxation according to Jacobsen (PMR). There you have to tense a specific muscle (like you hand, your upper or lower arm, your foot, etc.) for a few seconds and then relax it according to instructions. Then you should focus on the difference between the tension and the relaxation as well as the difference between (say) the left and the right hand. This relaxation technique is popular in Germany (I don’t know about elsewhere) however it does not work for me. (I tend to tension and relax my hands/fingers a lot anyways, especially when I'm not well, but I don't do it according to PMR guidelines; so therefore during the lessons I had to (try to) stop that.)  That’s not their fault, obviously, however I had to do the relaxation class during the entire time of my stay there, even though it had – if any – the opposing effect on me. Most of the time the instructor read the instructions from a piece of paper, but occasionally they just played a tape. Still, the fact that you had to go there may be helpful for people for whom the PMR works but who don’t have the motivation to do it on their own, when they are not forced to. (I find it hard to find any empirical evidence that it works for depression, though.) 

However, I think they vastly overestimate the amount of people from whom it works, because they did not accept any kind of negative feedback. At the end of each lesson there was a feedback round where you had to say how you are now and most people stated that they felt more relaxed. However, if you stated that you weren’t relaxed you still had to make up something which supposedly was better (which reminds me of research). My room-mate suggested I’d just say I’d me more relaxed to have my peace (which REALLY reminds me of research).

However, the one thing that was helpful about the PMR for me was having the appointment (where I had to go) itself; it structured the day a bit. But over all, I had preferred if I hadn’t had to go there.

I may or may not describe the other parts as well. 
Don’t know yet.
