20 Binge eating disorder Flashcards
How was binge eating disorder described in DSM-IV?
It wasn’t! Haha, trick question! Hahaha! It’s new to DSM-5.
What two symptoms characterise an episode of binge eating? (this is the A criterion of Binge Eating disorder)
A. Recurrent episodes of binge-eating. An episode of binge-eating is characterised by both of the following:
- Eating, in a discrete period of time (e.g. within a two-hour period) an amount of food that is definitely larger than most people would eat in a similar period of time under similar circumstances.
- A sense of lack of control over eating during the episode (e.g., a feeling that one cannot stop eating or control what or how much one is eating)
Binge-eating episodes are associated with three (or more) of the following… (Criterion B of Binge Eating disorder)
- Eating more rapidly than normal
- Eating until feeling uncomfortably full
- Eating large amounts of food when not feeling physically hungry
- Eating alone because of feeling embarrassed by how much one is eating
- Feeling disgusted with oneself, depressed or very guilty after overeating
How often must binge-eating occur, on average? (Criterion D)
The binge-eating occurs, on average, at least once a week for three months.
What compensatory (i.e. purging) behaviours are associated with binge-eating disorder? (Criterion E)
None. This what separates it from AN and BN.
What’s the male/female split in binge eating disorder?
1:1 –only eating disorder with a 50/50 male/female split.
What’s the lifetime prevalence of binge eating disorder?
3-5%
What’s the most common physiological problem associated with binge eating?
Overweight or obesity
Why is obesity not classified as a psychopathology?
It does not appear to involve a consistent psychological syndrome.
What did Latner et al. (2003) discover about the obesity stigma among children?
In a picture line-up of girls with various disabilities, the obese one was liked least.
What psychological problems are associated with obesity?
- Dementia
2. Cognitive deficits, especially in the area of executive function
How might levels of inflammation in the body affect the behaviour of the obese (Smith et al. 2011)?
Too much eating leads to inflammation in the body. This starts to affect executive function, which impacts on self-regulation, leading to more eating and more inflammation.
What is the IOWA Gambling Task and what does it test?
Four decks. 1 and 2 are bad decks – giving high yields but ultimately losing money. 3 and 4 are good decks – giving low yields but ultimately winning money.
It tests decision-making ability.
What evidence has been amassed from testing individuals with excess weight, AN and substance use disorder on the IOWA Gambling Task?
Overweight women –more weight, worse score
Anorexics –show inverted U curve, as opposed to positive linear learning in normals. Similar to individuals with VMPFC lesions.
Substance use –early learning tails off, but better than ANs and VMPFC lesions.
What four points might a CBT intervention for binge eating disorder involve?
- Develop a moderate eating plan
- Increase physical activity
- Achieve greater acceptance of body shape and weight
- Overcome barriers to change
