1
Q
what was the aim?
A
- to investigate whether problems in judging body actions such as deciding whether a body fits through a space, occurred only when judging one’s own body or whether it was an overall judgement problem
2
Q
summarise the procedure used
A
- study approved by an independent ethics committee, information sheet for informed consent
- 51 different openings 30-80 cm wide projected onto a wall in a random order, each 4 times
- condition 1 = 1PP where they judged their own body
- condition 2 = 3PP where they imagined the experimenter going throgh the opening
3
Q
describe the characteristics of the experimenter
A
- 28 years old
- 1.6 m
- weighed 52 kg
4
Q
when was an opening considered a perceived critical opening?
A
- when it had a yes response 50% of the time
- ratio obtained by dividing the perceived critical opening size by shoulder width of the participant
- when perceived critical opening had a value of 1 it meant it was the same size as shoulder width so they couldn’t fit
5
Q
what was the sample used?
A
- 50 young female participants
- 25 with AN from an eating disorder clinic and 25 healthy controls
- all students from Lille and matched on age and education
- interview to check for no comorbidity
6
Q
what were the statistics of BMI for the AN group compared to the controls?
A
- AN group = 15.6
- CONTROL group = 22.1
7
Q
what assessments were done beforehand?
A
- height, shoulder width and weight were standardised
- changes over time in nutritional status (6 months before study and at the time)
- data about body dissatisfaction using questionnaires e.g. body shape questionnaire
8
Q
what were the results from the study?
A
- AN group had significantly higher score on the body shape questionnaire
- AN group showed a significant overestimation of their own body size which meant perceptual ratios in the 1PP condition were significantly higher than for controls
9
Q
what was the differences in ratios for the AN group for 1PP and 3PP?
A
- 1PP = 1.321
- 3PP = 1.227
- control group showed no significant difference
10
Q
what conclusions can be made?
A
- those with AN significantly overestimated their own possibility in relation to the control group
- AN patients said that they felt larger than they were
- didn’t make errors when judging the experimenter just themselves
- thought to be due to body schema issues
11
Q
what can be said about generalisability?
A
- all female sample mean age 23.84 so doesn’t represent AN in males
- ethnocentric sample, all from Lille so not representative of AN in other cultures which may have different beauty standards
12
Q
what can be said about reliability?
A
- standardised procedures used e.g. 50 openings 30-80 cm wide
- can look for consistency of anorexic perceptions width
13
Q
what is an application of the study?
A
- perception is a huge application in AN
- informs treatments of CBT to change the faulty thinking patterns and re-establish positive thinking patterns
14
Q
what is a point about controlling ppt variables for validity?
A
- e.g. perceptual issues and comorbid factors such as depression
- create a clear cause and effect relationship between perception and body width
15
Q
what point can be made about triangulation?
A
- quantitative data = from BMI
- qualitative data from BSQ
- more accurate understanding of cognitive distortions of AN individuals
