Contemporary Guardia 2012 Flashcards
(5 cards)
aim of guardia 2012
investigated whether ANs and controls would be different in judging whether a critical opening was big enough to pass through
to continue previous research that said ANs misjudged their own size by applying it to judging other people
sample of guardia
low generalisability due to a small sample of 50 females
they used a matched pairs design between 25 women with AN from a clinic and 25 healthy women, based on age and education
all participants were from France with a mean age of 24
because these characteristics were controlled, this study is ethnocentric as it is not representative of non-european countries and their body perception if they have AN, and it is also gynocentric as it isn’t representative of males with AN.
very low in generalisability to a wider population of AN patients.
procedure of guardia 2012
standardised procedure. 2 conditions were used with 52 different wall projections each presented 4 times – the 1PP conditions was where ppts judged if their own body would fit through an opening by imagining themselves walking through it, and the 3PP condition was where ppts judged whether the same experimenter, standing 5.9m from the projection each time, could fit through the opening.
study can be easily replicated to test for reliability of the findings, as we know excatly what steps were taken to produce the results, increasing reliability.
results of guardia 2012
Healthy controls had a lower score than AN on body shape questionnaire, and lower mean perceptual ratios in 1PP (1.106 in cont., 1.321 in AN)
The mean ratio for the AN group was 1.321 and for controls it was 1.106, suggesting that patients hadn’t adapted internal body image to reality. The 3PP mean perceptual ratios for both conditions weren’t significantly different
conclusions of guardia 2012
those with AN significantly overestimated their body size, with a correlation between AN group and their pre-illness sizes
not a perceptual issue but internalised body dysmorphia.
Therefore, this study is applicable to the development of therapies such as CBT, as Guardia’s understanding of a cognitive cause for AN allows us to tailor treatments to individuals.
