Examining Mandometer(r) Founders' 10 "Reasons" Why Eating Disorders Are Not Mental Disorders – Part II

Tetyana 8 Comments

This is the last post in my mini-series on the Mandometer® Treatment. (Links to earlier posts here: Part I, Part II, and Part III). In this post I’m going to continue examining Bergh et al.’s reasons for why eating disorders are not mental disorders (#6-10). In my last post I omitted something important: I didn’t define mental disorders, but to avoid repeating myself, please see my comment on the topic here.

Bergh et al.’s reason #6 why EDs are not mental disorders:

Reason #6. Gender differences argue against an underlying mental health disorder. Women constitute more than 90% of eating disorder patients (Hoek & van Hoeken, 2003), but teenage males are more likely to have OCD than teenage females (Fireman, Koran, Leventhal, & Jacobson, 2001), and there are no differences in the prevalence of anxiety and anxiety-related disorders in male and female teens (Beesdo, Knappe, &

Examining Mandometer(r) Founders' 10 "Reasons" Why Eating Disorders Are Not Mental Disorders

Tetyana 9 Comments

This is Part III of my mini-series on the Mandometer® treatment. In my first post, I wrote about the history and rationale of the Mandometer® treatment. In my second post, I evaluated a recent study published by the creators of Mandometer® (Bergh et al., 2013); I wanted to see whether their data supported their claims (spoiler alert: it didn’t). In this post, I’m going to focus on the first five of Bergh et al.’s ten reasons why eating disorders are not mental disorders (or something like it, anyway).

If it seems like I have a personal vendetta against Cecilia Bergh & Co/Mandometer®, rest assured that I most certainly do not. I just don’t like bad science, misleading claims, and snake oil. As I mentioned in my first and second posts, I actually like many of the components of the Mandometer® treatment. (For example, I agree that weigh restoration … Continue reading →

2013 in Review: Most Popular Posts & Most Searched Queries of 2013

Tetyana

It is 2014! How did that happen? The year went by quickly; I defended my MSc, settled comfortably into self-employment, made huge strides in my recovery, and went to my first eating disorder conference.  I also helped Liz with psychoeducation seminar on Reward Systems in Eating Disordes, which she delivered in November at Sheena’s Place. It as a blast and I learned a lot from Liz. (Maybe I’ll organize myself and deliver my own seminar’s at Sheena’s Place in the near future. That would be fun.)

2013 was a busy year for me, but it was awesome. Really awesome. So awesome that posting frequency decreased in the last few months of 2013. And although I’m not making any promises for 2014, I do hope to write more. There’s so much left to write about! So many topic to cover.

I’d like to give a big thanks to SEDs … Continue reading →

The Finest Quality Snake Oil: Mandometer(r) Treatment for Eating Disorders – Part II

Tetyana 16 Comments

This is Part II of my mini-series on the Mandometer(r) treatment for eating disorders (link to Part I). In Part I, I provided some background on the Mandometer(r) treatment; in this post, I want to take an in-depth look at the recent Mandometer treatment study. My main goal is to see whether their data live up to their claims. Warning: This post may contain high levels of snark.  

Their main claims? This is from the abstract:

The estimated rate of remission for this therapy was 75% after a median of 12.5 months of treatment. A competing event such as the termination of insurance coverage, or failure of the treatment, interfered with outcomes in 16% of the patients, and the other patients remained in treatment. Of those who went in remission, the estimated rate of relapse was 10% over 5 years of follow-up and there was no mortality.

The Finest Quality Snake Oil: Mandometer(r) Treatment for Eating Disorders – Part I

Tetyana 6 Comments

PROTIP: When selling your snake oil treatment, try NOT to make wildly outrageous efficacy claims. But if you can’t resist that temptation, try to limit your hard-to-believe, eye-roll-inducing claims to your treatment — there’s no need to go further.

In this post, I’m going to give a brief history of the Mandometer® treatment and its apparent rationale. In the next one or two posts, I will do an analysis of the most recently study by the group that claims to show remission rates of 75% and relapse rates of only 10%. Sounds great, right? Well… we’ll see.

We suggest that the reason self-starving patients do not fit the DSM-IV criteria of anorexia nervosa is because there is in fact no psychopathological basis of the disorder … The DSM-IV offers no definition [of psychopathology], but it is reasonable to assume that a psychopathological basis of anorexia nervosa would be reflected

The Sobering Reality (and the Silver Lining) of Treating Anorexia Nervosa in Adults: A Randomised Controlled Trial

Tetyana 5 Comments

The challenges of treating anorexia nervosa are plenty; some of these challenges — like low prevalence rate and high treatment dropout rate —  make conducting randomised controlled trials aimed at identifying effective treatment methods really hard as well.

So I was pretty excited about the recently published randomised controlled trial comparing focal psychodynamic therapy (FPT), cognitive behaviour therapy (CBT), and optimised treatment as usual in adult (a harder to treat demographic than adolescents) anorexia nervosa patients.

Reading the paper, I was pretty impressed with how good the study design was; I’m not going to go into all the nitty-gritty details, but if you have access to and the chance to read the paper, do it. You’ll appreciate, I think, the amount of effort that went into this.

THE STUDY

Patients were recruited from ten universities across Germany. They had to be adult females with a BMI between 15-18 and with … Continue reading →

How you doin'? Differences in Psychological Well-being Between Anorexia, Bulimia, and Binge Eating Disorder Patients

Tetyana 3 Comments

Good health is more than just the absence of illness; it is more than just the absence of dysfunction. Good health — that is, mental, social, and physical health — requires the presence of wellness, or the ability to function well.

In this respect, with regard to eating disorders, most research has focused on assessing (health-related) quality of life and subjective well-being of eating disorder patients, often focusing on things like body satisfaction, self-esteem, and positive and negative emotions. There is, however, another way to think about well-being. A model (and assessment scale) developed by Carolyn Ruff, called psychological well-being (also here), aims to assess specific dimensions of functioning that contribute to or make-up well-being. There are six such dimensions.

Ryff Scales of Psychological Well-being:

  1. self-acceptance (positive self-evaluation)
  2. a sense of continued growth and development
  3. a sense of purpose and meaning in life
  4. a sense of self-determination and autonomy

Cognitive-Behavioural Therapy for Bulimia Nervosa in the “Real World”: What's the Evidence?

Tetyana

Cognitive-behavioural therapy (CBT) is commonly described as the evidence-based treatment for bulimia nervosa. But do the findings from nearly perfectly crafted trials, with stringently followed protocols and “ideal” participants apply to the “real world”? How generalizable are the findings from carefully selected participants to clinical populations where, for one, the prevalence of psychiatric comorbidities is relatively high?

In other words, CBT has been shown to be efficacious (i.e., it works in a controlled experimental research trial setting) but is it effective (i.e., does it work in a clinical setting where clients might have multiple diagnoses and complex needs)?

This is precisely the question that Glenn Waller and colleagues sought to answer. They wanted to see whether CBT would work in a “routine clinical setting, where none of the exclusion-and protocol-based constraints […] apply.”

PARTICIPANTS

Participants were recruited from a publicly-funded outpatient ED service in the UK. The only exclusion criteria … Continue reading →

Demystifying the Genetic and Environmental Influences on Disordered Eating

Tetyana 8 Comments

Genetics play an important role in the development of eating disorders and disordered eating behaviours. To date, many (over 30!) twin studies have been done and all but two found significant genetic effects on the development of eating disorders and disordered eating. However, no methodology is without limitations and tentative conclusions become more convincing when the findings are confirmed using different experimental approaches.

Twin studies, while they offer many advantages, are not that good when it comes to detecting shared environmental effects on a particular trait (literally, evens that happen to both twins and affect them in the same way). Fortunately, twin studies are just one of several different ways that researchers can use to study heritability. (A quick reminder: Heritability measures the amount of the variability in an observable trait/behaviour that can be attributed to genetic variation. This is NOT the same as stating … Continue reading →

Emotion Fluctuations in Anorexia and Bulimia Nervosa: A Rollercoaster or Not So Much?

Tetyana 2 Comments

Restricting, bingeing, and purging are powerful ways to regulate emotional states. However, these behaviours probably play different roles in emotional regulation. Whereas restriction is hypothesized to pre-empt the onset of highly emotional states, bingeing and purging is thought to act as a coping mechanism to deal with overwhelming emotional states once they’ve already been activated. 

In BN there is abundant evidence that the binge–purge cycle functions as a means of emotion regulation. Binging [and I would arguing purging too! ] facilitates a temporary suppression of painful self-awareness and helps the self to dissociate from painful emotions or to block negative affect as demonstrated in both laboratory studies and diary studies in daily life.

In AN, restrictive eating patterns have been linked with a narrowing of emotional functioning, flattening of affect and lack of outward display of emotion. As such, Waller, Kennerley, and Ohanian (2007) argue that both binge– vomit-cycle and
