The Effect of Attention on Body Size Adaptation and Body Dissatisfaction

摘要（不超过4,000个字符，包括空格，清楚地解释该项目涉及的EPSRC研究领域-更多信息请参见背面）在这个博士学位中，我的目标是设计一种潜在的干预措施，可用于治疗身体形象障碍，包括身体大小和形状的误解和身体不满。对身体大小和形状的误解以及对身体的不满都是饮食失调的危险因素和症状，如神经性厌食症和神经性贪食症。这项干预措施是基于一项研究，该研究表明，对身体不满程度高的人往往会将更多的注意力集中在理想化的身体尺寸上，并认为这些身体更“正常”。我正在进行一系列实验，以测试训练人们将注意力从理想化的身体上转移开是否会减少对身体大小和形状的误解以及对身体的不满。这些实验由参与者在线完成，如果结果有希望，我们的目标是最终将其作为一个智能手机应用程序进行试验，供患者在临床环境中使用。这个博士项目与EPSRC的研究主题“健康和护理的数字技术”有关，因为我们的目标是设计一种可以由患者在线完成的干预措施，这将比用于治疗身体形象障碍的传统谈话疗法更具成本效益。

Abstract(no more than 4,000 characters including spaces, clearly explain which EPSRC research area the project relates to - for more info see overleaf) In this PhD I aim to design a potential intervention that can be used to treat body image disturbances, including body size and shape misperception and body dissatisfaction. Both body size and shape misperception and body dissatisfaction are risk factors and symptoms of eating disorders, such as anorexia nervosa and bulimia nervosa. The intervention is based on research showing people with high body dissatisfaction tend to direct more attention towards idealised body sizes and perceive these bodies as more "normal"-sized. I am running a series of experiments to test whether training people to direct attention away from idealised bodies can lead to a reduction in body size and shape misperception and body dissatisfaction. These experiments are completed by participants online and, if the results are promising, we aim to eventually trial them as a smartphone app that can be used by patients in a clinical setting. This PhD project relates to the EPSRC research theme"Digital technologies for health and care" because we aim to design an intervention that can be completed online by patients, which will be more cost effective than traditional talking therapies used to treat body image disturbances.
