Pregnancy is a special period that is strongly influenced by dietary interventions, and many pregnant women develop gestational diabetes caused by conditions such as poor diet. Eating behavior interventions for women during this period are therefore very important, but unfortunately, there is a lack of established studies on intuitive eating in pregnant women.
This study examined the psychometric properties of a Chinese version of the IES-2 scale adopted in a group of pregnant women, as well as the relationship between intuitive eating characteristics and dietary quality. A total of 581 pregnant women completed the study which included the Intuitive Eating Scale (IES-2), the Depressive Symptom Scale (EPDS), the Anxiety Symptom Scale (SAS), the Parenthood Stress Scale (PPS), and The Dietary Guidelines Adherence Index for Pregnant Women during Pregnancy (CDGCI-PW).
The results show that the modified scales have good quality in the Chinese pregnant women population (CMIN/DF = 1.756, CFI = 0.925, TLI = 0.909, RMSEA = 0.037) and that the scale scores are correlated with depression and anxiety of pregnant women and correlated with overall diet quality during pregnancy.
The final six factors (avoiding forbidden foods, avoiding emotional eating, body.food choice congruence, avoiding food-related coping strategies, permission to eat, and reliance on hunger and satiety cues) structure of the revised IES-2 was confirmed. Moreover, the higher the intuitive diet, the better the quality of the pregnant woman's diet will be. This scale can further assess eating behaviors in different pregnancy states within the Chinese pregnant women population.
孕期是一个受饮食干预影响很大的特殊时期，许多孕妇因饮食不佳等情况患上妊娠期糖尿病。因此，针对这一时期女性的饮食行为干预非常重要，但遗憾的是，目前缺乏关于孕妇直觉性饮食的既定研究。
本研究考察了中文版IES-2量表在一组孕妇中的心理测量特性，以及直觉性饮食特征与饮食质量之间的关系。共有581名孕妇完成了该研究，研究内容包括直觉性饮食量表（IES-2）、抑郁症状量表（EPDS）、焦虑症状量表（SAS）、育儿压力量表（PPS）以及孕期孕妇饮食指南依从性指数（CDGCI-PW）。
结果显示，修订后的量表在中国孕妇群体中具有良好的质量（CMIN/DF = 1.756，CFI = 0.925，TLI = 0.909，RMSEA = 0.037），且量表得分与孕妇的抑郁和焦虑相关，与孕期总体饮食质量相关。
修订后的IES-2最终的六个因素结构（避免禁食食物、避免情绪化进食、身体-食物选择一致性、避免与食物相关的应对策略、进食许可、以及依靠饥饿和饱腹感信号）得到了确认。此外，直觉性饮食越高，孕妇的饮食质量就越好。该量表可进一步评估中国孕妇群体中不同孕期状态下的饮食行为。
