Intuitive eating, which involves following internal cues of hunger and satiety to guide eating choices, would be better understood if studied at the individual momentary level instead of globally or cross-sectionally. The current study employed ecological momentary assessment (EMA) to examine the ecological validity of a popular intuitive eating measure, the Intuitive Eating Scale (IES-2).
College males and females completed a baseline assessment of trait levels of intuitive eating as measured by the IES-2. Participants then followed a seven-day EMA protocol where they completed brief smart phone assessments about intuitive eating and related constructs while in their natural daily environments. Participants were asked to complete recordings before and after eating about their state level of intuitive eating at that moment.
Among 104 participants, 87.5% were female, mean age was 24.3, and mean BMI was 26.3. Baseline trait level intuitive eating was significantly correlated with state level intuitive eating reported across EMA recordings, with some evidence suggesting that correlations were stronger before eating compared to after eating. Intuitive eating generally was related to less negative affect, fewer eating restrictions, and more anticipated taste enjoyment before eating, as well as less guilt and regret after eating.
Individuals who reported high trait levels of intuitive eating also reported following their internal cues for hunger and satiety and had less guilt, regret, and negative affect surrounding eating in their naturalistic environments, thereby supporting the ecological validity of the IES-2.
如果在个体即时水平上而不是整体或横截面上研究,那么对直觉进食(即通过饥饿和饱腹感的内部提示来指导进食选择)的理解会更加深入。本研究采用生态瞬时评估(EMA)来检验一种流行的直觉进食测量工具——直觉进食量表(IES-2)的生态有效性。
大学生男性和女性完成了 IES-2 对特质水平直觉进食的基线评估。然后,参与者遵循了为期七天的 EMA 协议,在自然日常环境中完成了关于直觉进食和相关结构的简短智能手机评估。参与者被要求在进食前后记录他们在那一刻的直觉进食状态水平。
在 104 名参与者中,87.5%为女性,平均年龄为 24.3 岁,平均 BMI 为 26.3。基线特质水平的直觉进食与 EMA 记录报告的状态水平的直觉进食显著相关,有证据表明,进食前的相关性强于进食后。一般来说,在进食前,直觉进食与较少的负面情绪、较少的饮食限制和更多的预期味觉享受有关,而在进食后,与较少的内疚和后悔有关。
报告高特质水平直觉进食的个体也报告说他们遵循内部饥饿和饱腹感的提示,并且在自然环境中围绕进食的内疚、后悔和负面情绪较少,从而支持 IES-2 的生态有效性。
