Patients with anorexia nervosa often report a conscious alteration of body image representation, with both body overestimation and body dissatisfaction. Cognitive and behavioural therapy is effective for treating many psychiatric disorders but often fails to treat anorexia nervosa and body image distortions. Although patients are aware of their weight loss, they continue to feel overweight - as if there were a conflict between a previous (maybe already false) body representation and the new one. These distortions are linked to negative emotions focused on the body but which can extend to the self (e.g. disgust and sadness).
The present case report is the first in which the Appraisal Tendency Framework has been applied to decrease body image distortions in a patient with anorexia nervosa. The Appraisal Tendency Framework is usually used to understand how emotions influence decision making. Here, we report on a 24-year-old woman who suffered from anorexia nervosa and body image distortions, and was treated as an inpatient with conventional cognitive and behavioural therapy for an eating disorder. Body image distortions were assessed before and after the patient completed an adaptation of the Iowa Gambling Task, coupled with the induction of a heuristic processing emotion. We hypothesized that allowing the patient to focus on the emotional cues in the modified Iowa Gambling Task would improve her decisions about her true body shape.
All body image measures were improved after the protocol. Consequently, we suggest that the Appraisal Tendency Framework might be a valuable means of investigating body image issues in eating disorders and anorexia nervosa. Further studies are required to expand and detail these findings.
神经性厌食症患者常报告有意识地改变身体形象认知,既有身体高估又有身体不满。认知行为疗法对治疗多种精神疾病有效,但往往无法治疗神经性厌食症和身体形象扭曲。尽管患者意识到自己体重减轻,但仍觉得自己超重——就好像以前(可能已经有误)的身体认知与新的认知之间存在冲突。这些扭曲与关注身体的负面情绪有关,但可能会扩展到自我(如厌恶和悲伤)。
本病例报告首次将评估倾向框架应用于减少神经性厌食症患者的身体形象扭曲。评估倾向框架通常用于理解情绪如何影响决策。在此,我们报告一名24岁患有神经性厌食症和身体形象扭曲的女性,她作为住院患者接受了针对饮食失调的传统认知行为疗法治疗。在患者完成爱荷华赌博任务的改编并诱发启发式加工情绪前后,对身体形象扭曲进行了评估。我们假设让患者专注于改良后的爱荷华赌博任务中的情绪线索会改善她对自己真实体型的判断。
方案实施后,所有身体形象指标均得到改善。因此,我们认为评估倾向框架可能是研究饮食失调和神经性厌食症中身体形象问题的一种有价值的方法。需要进一步研究来扩展和细化这些发现。
