13 - eating disorders and body dysmorphia Flashcards
What is the meaning of the word anorexia nervosa?
→ An: Lack of
→ Rexia: appetite
→ Nervosa: of the nervous system
What are the 2 main features of anorexia nervosa?
1) Active restriction of energy intake, relative to what the person needs which leads to a significant low body weight in the context of age, sex, developmental trajectory, and physical health
→ you can compare weight to percentile, to developmental growth
2) Overvaluation of shape, weight, and their control
→ judging self-worth, largely or exclusively in terms of shape, weight and the ability to control them
→ core psychopathology of eating disorders (the core ingredient of eating disorders)
What is the meaning of the word bulimia nervosa?
→ Bu: ox (animal)
→ limia: appetite
→ (i.e., having the appetite of an ox, so eating a lot)
What are the 3 main features of bulimia nervosa?
1) Recurrent binge eating
→ an episode of eating an objectively large amount of food
→ objective vs. subjective binge (important to make this distinction)
→ sense of loss of control
2) Extreme method (one or more) of weight control
→ p.ex: purging, using medication that make you lose weight faster, etc.
3) Overvaluation of shape, weight and control (core ingredient)
The binge eating and inappropriate compensatory behaviours are required to occur, on average, at least once a week for 3 months
The extreme methods of weight control in bulimia are a lot like…
- These extreme methods of weight control are a lot like safety behaviours, BUT we have to ask what the function is of that behaviour
→ p.ex: to undo the effects of food that you’ve eaten; to relieve feelings of anxiety
→ just because you’re seeing self-induced vomiting, doesn’t mean it’s necessarily an ED
What is binge eating disorder?
- No core ingredient of overvaluation of shape and weight, it’s really just a sense of loss of control
- One primary feature of recurrent binge eating
–> Occurs in the absence of the extreme weight-control behaviour seen in bulimia - Marked distress regarding binge eating, accompanied by shame and self-criticism
Required to occur at least once a week for 3 months
What are other specified eating disorders?
- Atypical anorexia nervosa: anorexia BUT not at a significantly low weight
- Bulimia nervosa (of low frequency and/or limited duration)
- Binge-eating disorder (of low frequency and/or limited duration)
- Purging disorder
- Night eating syndrome
Why is it difficult to frame EDs in categories?
→ it’s difficult to frame EDs in this way because a lot of people aren’t falling into the categories, but do still present symptoms
What is body shape dissatisfaction?
- Refers to not liking smt about your body, which is extremely common) or “normative discontent” vs. “overvaluation of shape/weight”
→ “body shape dissatisfaction” is contrasted by shaping your entire sense of self on your body image
What is the family-based approach?
Treatment manual for anorexia nervosa
- Focused on getting the family involved in the intervention, because when young people are at significantly low weight, it really is an emergency (can lead to heart problems, bad bones, etc.)
→ we have to see how they lost a significant amount of weight over a period of time, not only if they look like they’re at a normal weight
- “Establish that there is a crisis in the family and begin the process of defining and enhancing parental authority to manage the crisis”
→ in a lot of problems, we usually have a lot of lee-way to let people go at their own pace BUT, with anorexia, as someone continues to be below weight, there’s an impairment in thinking that’s occurring (less flexible in thinking)
→ so, we’re on a life or death timeline here, we need to establish that this is incredibly serious
- “You are the people with the biggest investment of love and commitment to your daughter, so you are also the ones most likely to help the most with this problem”
→ because the interventions really have to play out in the home at meal times
→ parents play a big role in turning it around
→ “Your daughter is desperately ill and something very drastic has to happen for you to save her life” AND “You must be devastated and worn out by this terrible ordeal…”
→ this is a therapeutic bind: disorient the family AND be kind and containing at same
→ this is often the balance that needs to be found with any crisis
→ you’re trying to really up the anxiety in the parents, they need to see it as a crisis with a time-limit
EDs are usually ___ at the start, this is common thinking (i.e., “this is good that I have control over my eating”)
Egosyntonic: meaning they’re happy with it and it aligns with their goals
- BUT, with time, they become egodystonic
How do we coach parents in the family-based approach?
→ “You have to provide your daughter, who is starving, the kinds of food that would restore her weight to normal”
→ “It is full-cream milk and pasta with a cream sauce that will make the difference, not salad”
→ the first step is usually this re-feeding process, because the girl is nutritionally lacking
What is the therapy for adolescents with EDs?
Cognitive behaviour therapy for adolescents with EDs
What is the transdiagnostic cognitive behavioural theory disorders?
- Starts with the core ingredient of overvaluation, then leading to strict-dieting or taking control over input
→ usually very restricting caloric intake, much smaller than needs
→ this restriction is usually the antecedent of binging
→ binging is preceded by restriction: if you don’t eat enough during the whole day, you feel like you need to eat more by the end of the day, your body is built to try to compensate for that
→ no one can handle that level of restriction for so long, so we binge, which then leads to the compensatory behavior (vomiting p.ex) - Features of under-eating (weight is low or not): peoples minds become foggy, concentration decreases, flexibility in thinking decreases, changes in mood, etc.
What happens in ED according to the transdiagnostic theory?
- You end up in cycles that are related to interoceptive feelings
→ p.ex: feeling full is interpreted as feeling fat
→ a body sensation that you basically have no choice but to have, but if it’s interpreted as “my worst fear has come true” then it’s gonna become a problem in the cycle
What are downsides of having self-worth be determined by shape/weight/eating?
- We often see over-checking of shape and weight or complete avoidance of checking
- Preoccupation: topic that is very often on the person’s mind
- Mislabeling aversive states as “feeling fat”: low emotions, interoceptive feelings, etc.
- A lot of behavior and energy is surrounding this one domaine
What occurs during the over-evaluation of shape and weight and their control?
- Dietary restraint
- Shape and weight checking and/or avoidance
- Preoccupation with thoughts about shape and weight
- Mislabelling adverse states as “feeling fat”
- Marginalization of other areas of life
The last 4 having a bidirectinoal relationship with the overvaluaion
What is the Minnesota experiment?
- During the 2nd world war
- 36 young men were conscientious objectors (part of free churches, that had passivism as a core belief, meaning they thought it was wrong to participate in a war, BUT they still wanted to help in how they could)
- The researchers fed them much less food than necessary
→ they had conditions where they tried to re-feed them in different ways to figure out the best way to re-nourish people, because there was a famine in Europe
What were the effects (beheavioural, psychological, physical) of the Minnesota experiment?
Behavioural effects
- Eating rituals: eating slowly, cutting food into small pieces, ingesting very hot food
- Reading cookbooks and collecting recipes
- Increasing use of salt, spices, gums, hot soup & water, coffee and tea
- Nail-biting
- Increased smoking
- Binge-eating episodes
- Self-mutilation
Psychological effects
- Impairment of concentration
- Poor insight and critical judgement
- Preoccupation with food & eating
- Depression; mood swings; irritation; hunger; anxiety; apathy
- Psychotic episodes; personality changes; social impairment; social withdrawal
- Loss of sexual appetite
Physical effects
- Abdominal pain; gastrointestinal discomfort
- Sleep disturbances, vertigo
- Headaches; weakness; hypersensitivity to light and noises
- Cold intolerance
What is “regular eating”?
- Early stage in intervention is “Regular eating”
→ if there’s severe restriction happening, this is inconsistent with it; this also makes binging less likely, because part of what causes binges is restriction, so if we eat every few hours, we interrupt the cycle - Not very specific in what you eat, as long as you’re eating smt for each meal
Pattern of eating: - Breakfast
- Mid-morning snack
- Lunch
- Afternoon snack
- Evening meal
- Evening snack
Points to note: - Eat these meals and snacks, but do not eat between them
- Do not skip any meals or snacks
- Do not go for more than 4 hours w/o eating
- Eat what you like in the meals and snacks, but no vomitting or laxatives to compensate
- Always know when (and roughly what) you are going to eat next
How does “feelings of fatness” vary along with actual weight?
- The feelings of fatness go up and down during the day, if you’re already vulnerable you’ll feel it more
- So we’ll have a set weigh-in every time they visit, and it’s graphed over time (and they can’t weigh themselves between this) to show them the actual stability in their weight
- The estimate of what it is is often inaccurate when based on feelings (we’ll ask what they think they’re weighing)
- We can do the same thing with shape (measuring tape over certain parts of the body over time)
= We’ll show them the graph and their weight every time, BUT sometimes we only show it at the end
What are some eating-related safety behaviours?
- Breaking food into pieces (that normally wouldn’t be)
- Odd mixing of foods
- Odd utensil use (fork for yogurt)

→ abusive laxatives/diuretics
→ fasting
What are some exercise-related safety behaviours?
→ Excessive bending/stretching
