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

进食障碍是出了名的难以治疗的疾病，通常出现在青春期中期，通常会一直持续到成年。它们有三个主要组成部分(认知-情感、行为和知觉)，其中认知-情感成分是CBTE9和预防性干预等治疗的主要靶点。然而，身体大小和形体知觉是一项关键的诊断标准，在预防性干预中通常不会针对这一标准。这项博士研究的目的是确定身体不满意的发展阶段(研究1)，以便在正确的年龄进行预防性干预；确定饮食紊乱的低风险或高风险女孩与饮食障碍女孩在注意偏差和身体意象差异方面的差异(研究2)；并利用研究3中的这些结果来调整镜子暴露疗法，作为针对饮食紊乱的感知成分的预防性工具。

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.
