Abstract

Objective: This study assessed the ecological validity of the Yale Food Addiction Scale (YFAS 2.0) with ecological momentary assessment (EMA) and explored the internal consistency and convergent validity of a momentary food addiction scale.

Method: Adults (N = 49) who met criteria for binge-eating disorder and/or food addiction (age = 34.9 ± 12.1 years; 77.1% cisgender female; 55.1% non-Hispanic White) completed online questionnaires and a 10-day EMA protocol. Analyses examined (a) associations between the YFAS 2.0 and EMA-measured variables corresponding to food addiction criteria, (b) reliability of a momentary food addiction scale (EMA-FA), and (c) concurrent associations between EMA-FA and EMA-measured negative affect, impulsivity, eating expectancies, body satisfaction, consumption of palatable food, and taste response to palatable food.

Results: YFAS scores were associated with EMA-reported variables corresponding to food addiction criteria (ps < .045). The multilevel reliability for EMA-FA was adequate (ω = .75-.94). Individuals with higher EMA-FA scores reported greater negative affect, impulsivity, appetite, palatable food consumption, taste response to palatable food, and contrary to expectations, greater body satisfaction (ps < .01). Within-person effects emerged for EMA-FA predicting higher negative affect, impulsivity, likelihood of palatable food consumption, more pleasurable taste responses after consuming palatable foods, yet lower body satisfaction, appetite, and eating expectancies (ps < .01).

Conclusions: Results support the ecological validity of the YFAS 2.0, and additional evidence of convergent validity and internal consistency was demonstrated for a momentary food addiction scale. This assessment of the psychometric properties of the YFAS will ultimately further its utility and relevance in the study and diagnosis of food addiction.

耶鲁食物成瘾量表 2.0 和瞬间食物成瘾症状的生态有效性。

研究目的本研究评估了耶鲁食物成瘾量表（YFAS 2.0）与生态瞬间评估（EMA）的生态有效性，并探讨了瞬间食物成瘾量表的内部一致性和收敛有效性：符合暴饮暴食障碍和/或食物成瘾标准的成年人（N = 49）（年龄 = 34.9 ± 12.1 岁；77.1% 顺性别女性；55.1% 非西班牙裔白人）完成在线问卷调查和为期 10 天的 EMA 方案。分析研究了（a）YFAS 2.0与EMA测量的与食物成瘾标准相对应的变量之间的关联，（b）瞬间食物成瘾量表（EMA-FA）的可靠性，以及（c）EMA-FA与EMA测量的负性情绪、冲动、进食期望、身体满意度、适口食物的消费以及对适口食物的味觉反应之间的并发关联：结果：YFAS得分与EMA报告的符合食物成瘾标准的变量相关（PS < .045）。EMA-FA的多层次信度良好（ω = .75-.94）。EMA-FA得分越高的人，其负面情绪、冲动性、食欲、适口食物消耗量、对适口食物的味觉反应越大，与预期相反，其身体满意度越高（ps < .01）。EMA-FA出现了人内效应，预测了更高的负面情绪、冲动性、食用适口食物的可能性、食用适口食物后更愉悦的味觉反应，但身体满意度、食欲和进食预期较低（PS < .01）：结果支持YFAS 2.0的生态效度，并证明了瞬间食物成瘾量表的收敛效度和内部一致性。对YFAS心理测量特性的评估最终将进一步提高其在研究和诊断食物成瘾方面的实用性和相关性。(PsycInfo Database Record (c) 2024 APA, 版权所有）。
