Title: Eating%20Disorders


1
Eating Disorders
www.psychlotron.org.uk
  • Cognitive model
  • Psychological disorders are the result of faulty
    or maladaptive thinking processes
  • Anorexia and bulimia may involve misperception of
    the body
  • They will also involve faulty reasoning about the
    self, the body and food/eating

2
Cognitive Distortions in EDs
www.psychlotron.org.uk
  • Faulty thinking in EDS typically includes
  • Misperceiving the body as overweight when it is
    actually underweight
  • Basing feelings of self worth unduly on physical
    appearance
  • Basing sense of self on control over eating/ED
    symptoms
  • Irrational/mistaken beliefs about
    food/fat/dieting behaviours

Cognitive Errors in EDs
www.psychlotron.org.uk
  • All or nothing thinking
  • I ate one biscuitthats blown everything!
  • Overgeneralising
  • If I fail at controlling my eating I fail in
    life.
  • Magnifying/minimising
  • My weight loss isnt serious.
  • Magical thinking
  • If I reach size 8 then my life will be perfect.

Cognitive Errors in EDs
www.psychlotron.org.uk
  • Fallon Rozin (1985)
  • Male female students rated themselves on
    current and ideal body shape
  • Compared to males, females rated themselves as
    heavier than what was attractive, and much
    heavier than their ideal

5
Cognitive Errors in EDs
www.psychlotron.org.uk
  • McKenzie et al (1993)
  • Female ED patients overestimated their own body
    size in relation to other women
  • They judged their ideal weight to be lower than
    comparable non-ED patients
  • Following a sugary snack, they judged their body
    size to have increased. Controls did not.

6
Cognitive Errors in EDs
www.psychlotron.org.uk
  • Women are generally more dissatisfied than men
    with their bodies
  • ED patients misperceive their own bodies and have
    more unrealistic body ideals
  • In ED patients, minor events related to eating
    activate fear of weight gain

7
The Cognitive Model
www.psychlotron.org.uk
  • AN and BN are certainly associated with biases
    and distortions in thinking
  • However, most women are dissatisfied with their
    bodies, not all of them develop EDs
  • A good account of what helps to maintain EDS, but
    not of what causes them in the first place.
