概括
耶鲁大学的食物成尺度2.0 (YFAS 2.0) 显示,症状与过度饮食障碍 (BSED) 措施的重叠是有限的. 然而,约有一半的YFAS 2.0症状存在于BSED措施中,这表明食物成研究中的部分共享内容.
科学领域:
- 精神病学和行为科学 精神病学和行为科学
- 临床心理学 临床心理学
- 成研究 研究成研究
背景情况:
- 食物成 (FA) 和暴饮暴食 (BSED) 之间存在很高的同时发生率.
- 目前尚不清楚这种重叠是否是由于各自措施评估的共同症状造成的.
- 耶鲁食品成量表2.0 (YFAS 2.0) 是FA的常见衡量标准.
研究的目的:
- 为了确定FA和BSED测量是否评估了类似的症状.
- 澄清YFAS 2.0是否与常见的BSED措施相比评估了不同的症状概况.
- 将比较重点放在BSED的FA和狂饮相关特征上,不包括补偿性行为.
主要方法:
- 对YFAS 2.0和五个突出的BSED措施进行了内容分析.
- 训练有素的编码人员将症状代码分配给每项措施中的项目.
- 在从BSED措施中删除了补偿性行为项目后,计算了Jaccard相似系数以量化症状重叠.
主要成果:
- 在YFAS 2.0中,与BSED措施的症状重叠非常低 (雅卡德范围:0.080.19).
- 大约47%的YFAS 2.0症状在至少一个BSED测量中被发现.
- 在BSED测量中不存在的YFAS 2.0症状集中在损伤和后果上,而BSED测量强调了饮食行为的认知特征.
结论:
- FA和BSED的措施有一些内容是相同的,但也有不同的特点.
- YFAS 2.0评估了与饮食行为相关的损伤的独特方面.

Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

Rewards can come in many forms such as a pleasant feeling, money, or food. However, sometimes an individual engages in compulsive behavior despite of negative consequences, and this state is known as addiction. Administration of addictive substances is neurochemically rewarding, which ultimately causes a loss of control in limiting the intake. Scientists aim...

1.6K
A binge-eating model was established in mice using intermittent access to M&M's (a highly palatable food made of fat and sugar). Mice with intermittent access to this high-fat, high-sugar food showed stress-like behaviors, increased caloric intake, and a preference for that food over standard chow compared to mice with continuous or no access to the...

04:19A Computer-Based Platform for Aiding Clinicians in Eating Disorder Analysis and Diagnosis
4.4K
Diagnosing eating disorders in healthcare is challenging. Therefore, the present protocol develops an algorithm based on 949 patient responses to a questionnaire, with the diagnosis displayed on an easy-to-use web-based interface. This system facilitates the accurate diagnosis of eating disorders while excluding those believed to have an eating disorder.
