How do attitudinal and perceptual factors influence the development of eating disorders?

饮食失调是一种众所周知的难以治疗的疾病，通常出现在青春期中期，并经常持续到成年。它们有三个主要组成部分（认知-情感、行为和感知），其中认知-情感部分是CBTE9等治疗和预防性干预的主要目标。然而，身体大小和形状感知是一个关键的诊断标准，往往不是针对性的预防干预。本博士的目的是确定身体不满意在发育的哪个阶段发展（研究1），以便在正确的年龄进行针对性的预防干预；确定进食障碍风险低或高的女孩与进食障碍女孩在注意偏差和身体形象差异方面的差异（研究2）；并利用研究3中的这些结果，将镜像暴露疗法作为一种预防工具，针对饮食失调的感知成分。

Eating disorders are a notoriously difficult condition to treat whichcommonly present in middle-adolescence and often persist intoadulthood. They have three main components (cognitive-affective,behavioural, and perceptual) of which the cognitive-affectivecomponent is the main target in treatment such as CBTE9 andpreventative interventions. However, the body size and shapemisperception is a key diagnostic criterion which is not often targetedin preventative interventions. The aim of this PhD is to determine atwhat stage of development body dissatisfaction develops (Study 1) inorder to target preventative interventions at the correct age; todetermine the difference in attentional bias and body imagediscrepancies between girls at low or high risk of disordered eatingand girls with an eating disorder (Study 2); and to use these results inStudy 3 to adapt mirror exposure therapy to be used as a preventativetool targeting the perceptual component of eating disorders.
