直觉饮食量表

直觉饮食（IE）是一种饮食方法，其特点是协调内在线索，并利用这些线索来指导与食物和饮食相关的行为。Tylka 和 Kroon Van Diest (2008) 的直觉饮食量表 (IES-2) 在成年人中得到了充分验证，但尚未在青少年早期得到验证。当前的研究旨在调整和验证适合青春期早期使用的版本（IES-2-EA）。

 使用探索性因素分析 (EFA) 对从 11 至 13 岁青少年 ( N = 471)的两个独立样本中收集的数据进行结构检查，并随后进行验证性因素分析 (CFA) 以确认假设的模型拟合。还检查了 IES-2-EA 分数与实际理想体型差异、身体欣赏、内感受意识和心理困扰的有效测量之间的关系。

改编后的 17 项 IES-2-EA 具有三因素结构，与为成人开发的原始版本有几个关键区别。在第一个青少年样本中，IES-2-EA 分数、身体欣赏、内感受意识、实际理想体型差异和心理困扰之间存在中度至强相关性（n  = 245）。二次 CFA 在第二个青少年样本 ( n  = 226) 中显示出良好的模型拟合度。

IES-2-EA 非常适合测量青少年早期的直觉饮食行为。这 17 个项目反映了类似于成人完成 IES-2 的三部分结构。这些早期数据表明，改编后的 IES-2-EA 具有可靠性和有效性的证据；这可能是研究和临床使用的有效措施。

Purpose

Intuitive Eating (IE) is an approach to eating characterised by attunement to intrinsic cues, and using those cues to guide behaviours related to food and eating. Tylka and Kroon Van Diest's (2008) Intuitive Eating Scale (IES-2) is well-validated in adults, but not yet among early adolescents. The current study was designed to adapt and validate a version suited for use in early adolescence (IES-2-EA).

Data collected from two independent samples of adolescents aged 11 to 13 (N = 471) were structurally examined using exploratory factor analysis (EFA), with a subsequent confirmatory factor analysis (CFA) to confirm hypothesised model fit. Relationships between scores on the IES-2-EA and validated measures of actual-ideal body size discrepancy, body appreciation, interoceptive awareness, and psychological distress were also examined.

The adapted 17-item IES-2-EA had a three-factor structure with several key differences from the original version developed for adults. Moderate-to-strong correlations were found between scores on the IES-2-EA, body appreciation, interoceptive awareness, actual-ideal body size discrepancy, and psychological distress in the first sample of adolescents (n = 245). Secondary CFA showed good model fit in the second sample of adolescents (n = 226).

The IES-2-EA is well-suited to measure intuitive eating behaviour among early adolescents. The 17 items reflect a three-component structure similar to that seen in adults completing the IES-2. These early data suggest the adapted IES-2-EA has evidence of reliability and validity; it may be an effective measure for research and clinical use.
