Background

This study aimed to explore the association of food addiction (FA) with eating-related psychosocial impairment and examine the extent to which this association was explained directly by FA symptoms themselves, versus through body image disturbance.

Materials and methods

Participants (356 university students and 544 crowdsourced adults) completed self-report measures of FA (Yale Food Addiction Scale; YFAS 2.0), psychosocial impairment (Clinical Impairment Assessment; CIA 3.0), and body image disturbance (Eating Disorders Examination Questionnaire; EDE-Q 6.0), and reported their body mass index (BMI) and gender.

Results

Endorsement of distress and/or impairment on the YFAS corresponded to ratings on the CIA. Structural equation models indicated the relationship between FA and eating-related psychosocial impairment was partially mediated by body image disturbance. The indirect effect of body image disturbance explained more variance in eating-related psychosocial impairment than did YFAS scores themselves. Neither BMI nor gender significantly moderated any direct or indirect pathways from food addiction to psychosocial impairment.

Conclusions

Food addiction is associated with clinical impairment in men and women across the weight spectrum. A large portion of psychosocial impairment associated with food addiction may be explained by body image disturbance. Due to its role in explaining psychosocial impairment, body image disturbance warrants increased attention in FA research.

身体图像障碍部分解释了饮食成瘾中与饮食有关的心理社会障碍

背景

这项研究旨在探讨食物成瘾（FA）与饮食相关的社会心理障碍之间的关联，并研究这种关联在多大程度上由FA症状本身直接解释，而不是通过身体图像紊乱来解释。

材料和方法

参与者（356名大学生和544名众包成人）完成了FA（耶鲁食品成瘾量表； YFAS 2.0），心理社会障碍（临床障碍评估； CIA 3.0）和身体形象障碍（饮食失调调查问卷； EDE-问题6.0），并报告了他们的体重指数（BMI）和性别。

结果

对YFAS的遇险和/或损害的认可对应于CIA的评级。结构方程模型表明，FA和饮食相关的心理社会障碍之间的关系部分是由身体形象障碍所介导的。与YFAS评分本身相比，身体图像障碍的间接影响解释了与饮食相关的社会心理障碍的更多差异。BMI和性别均未显着缓解从食物成瘾到社会心理障碍的任何直接或间接途径。

结论

在整个体重范围内，食物成瘾与男性和女性的临床损害有关。与食物成瘾有关的很大的社会心理障碍可能是由身体形象障碍引起的。由于其在解释心理社会障碍方面的作用，因此身体影像障碍值得在FA研究中引起更多关注。
