Eating disorders (EDs) are maintained by fear and anxiety, which lead to disordered eating behaviors thought to prevent the occurrence of feared outcomes. Fear of weight gain and food are among the most common fears present in the EDs. However, theory and clinical observation suggest that the feared consequences of eating or weight gain are diverse and individualized. Further research is needed to delineate specific fears underlying ED pathology.
167 participants with any ED participated in an online four-session imaginal exposure intervention. Imaginal exposure scripts were rated by trained coders using items derived from the Eating Disorder Fear Interview to identify fears present. Frequencies of fears present in scripts were quantified.
Two-thirds of scripts mentioned fears of food and weight or body-related fears. In over half of scripts, fear of judgment and fear of loss of control were identified. Diagnostic differences were found, including that those with anorexia nervosa (AN) and bulimia nervosa (BN) had highest fears of food, whereas those with AN and other specified feeding and eating disorder (OSFED) had higher weight gain/body-focused fears.
We were underpowered to make comparisons between ED diagnoses other than AN, BN, and OSFED.
Imaginal exposure scripts contained a large number of fears related to food, weight/shape, judgment, and loss of control, among others. These findings extend the current understanding of ED fears and provide evidence for the individualized and varied nature of fears. Identification of ED fears can further inform research on designing personalized, exposure-based treatment approaches.
饮食失调(ED)是由恐惧和焦虑维持的,这些恐惧和焦虑导致了紊乱的进食行为,据认为这些行为可以防止恐惧的结果发生。对体重增加和食物的恐惧是 ED 中最常见的恐惧之一。然而,理论和临床观察表明,进食或体重增加的恐惧后果是多种多样的,因人而异。需要进一步的研究来描绘 ED 病理背后的具体恐惧。
167 名患有任何 ED 的参与者参加了一个在线的四节想象暴露干预。想象暴露脚本由经过培训的编码员使用源自饮食失调恐惧访谈的项目进行评估,以确定存在的恐惧。脚本中存在的恐惧的频率被量化。
三分之二的脚本提到了对食物和体重或身体相关的恐惧。在超过一半的脚本中,确定了对评判的恐惧和对失控的恐惧。发现了诊断差异,包括神经性厌食症(AN)和贪食症(BN)患者的食物恐惧最高,而 AN 和其他特定的进食和饮食障碍(OSFED)患者的体重增加/身体相关恐惧更高。
我们的能力不足以在除 AN、BN 和 OSFED 之外的 ED 诊断之间进行比较。
想象暴露脚本包含了大量与食物、体重/体型、评判和失控等相关的恐惧。这些发现扩展了对 ED 恐惧的现有理解,并为恐惧的个体化和多样化性质提供了证据。识别 ED 恐惧可以进一步为设计个性化、暴露为基础的治疗方法的研究提供信息。
