Resource summary
Psychological Causes of Bulimia
Behavioural explanations - AO1
Social Learning Theory (SLT) - imitating our role models (e.g. skinny models/actresses)
Operant conditioning - praise/feeling good about weight loss, acting as a reinforcement
Who's vulnerable? - people with low self-esteem, perfectionists (OCD), high social anxiety, impulsive, controlling parents
Behavioural explanations - AO2
Groez et al (2002)
Meta-review of 25 studies.
Found a positive correlation between dissatisfaction and exposure to media images
Becker et al (2002)
Study done in Fiji (cross-cultural)
Found ED's didn't exist in Fiji until TV
Five years after, numbers of both AN and BN sufferers rose
Cognitive - AO1
Coopers Model
Most people with BN have suffered an early traumatic experience
Because of this they feel worthless
As they grow up they are extra sensitive to comments about themselves or media images
They learn that fat = bad, thin = good and begin to diet
They believe loosing weight will result in others liking them
The maintenance cycle
Person is feeling low so binge to feel better
Start to worry about getting fat so purge
Causes them to feel worthless, causing the cycle to repeat.
Polivy
BN sufferers have poor self-image, causing stress
Binge eating is a way of coping with this
Sufferers can blame their poor self-image on the binging, rather than their problems
An avoidance tactic
Cognitive - AO2
Cooper evidence - Leung et al
Lack of parental bonding was linked to dis-functional beliefs among BN sufferes
These have been linked to binging and purging in other studies.
Polivy evidence
Studied the effects of stress on dieters
Compared non-stressed to stressed, and found stressed ate more food
Supports binge eating being not about a desire for food, but a coping mechanism of stress
