Abstract

The Intuitive Eating Scale-2 (IES-2) is a measure of intuitive eating behaviors that has been extensively validated, with traditional latent variable modeling approaches, in youth and adults from many different populations, including college students in China. However, there is still a lack of research on the psychometric properties of the IES-2 in adults from the Chinese general population. Moreover, psychometric network analysis, as a complement to traditional latent variable modeling approaches, has not been used for examining the psychometric properties of the IES-2. Thus, the present study used a psychometric network approach to evaluate the psychometric properties of the IES-2 in Chinese adults from the general population. A sample of 700 Chinese general adults (50% women; Mage = 31.13 years, SD = 9.19) recruited online were included in the present study. Psychometric network analysis was performed. Exploratory graph analysis (EGA) identified four dimensions, which were well separated in the estimated network. The network structure showed excellent stability and metric measurement invariance (i.e., network loadings) across men and women. Furthermore, several items on the IES-2 were identified as key nodes in the network of the IES-2 that may be important for the development and maintenance of intuitive eating. For example, two items (i.e., “I trust my body to tell me when to eat,” and “I trust my body to tell me when to stop eating”) related to reliance on body cues were the most impactful nodes in the complete network. The findings of our study provide a greater understanding of the IES-2 from the perspective of network analysis and have implications for applications of intuitive eating interventions for general populations.

中国成年人直觉进食量表-2的心理测量网络分析。
直觉进食量表-2(Intuitive Eating Scale-2,IES-2)是一种测量直觉进食行为的量表,该量表已通过传统的潜变量建模方法在包括中国大学生在内的许多不同人群的青少年和成人中进行了广泛验证。然而,关于 IES-2 在中国普通人群中的心理测量特性的研究仍然缺乏。此外,心理测量网络分析作为传统潜变量建模方法的补充,尚未被用于研究IES-2的心理测量特性。因此,本研究采用心理测量网络方法来评估 IES-2 在中国普通成年人中的心理测量特性。本研究通过网络招募了 700 名中国普通成年人(50% 为女性;年龄 = 31.13 岁,平均年龄 = 9.19 岁)。进行了心理测量网络分析。探索性图分析(EGA)确定了四个维度,这四个维度在估计的网络中分离得很好。该网络结构在男性和女性之间表现出极好的稳定性和度量测量不变性(即网络负荷)。此外,IES-2 中的几个项目被确定为 IES-2 网络中的关键节点,这些节点可能对直觉饮食的发展和维持非常重要。例如,与依赖身体暗示有关的两个项目(即 "我相信我的身体会告诉我何时进食 "和 "我相信我的身体会告诉我何时停止进食")是整个网络中最具影响力的节点。我们的研究结果从网络分析的角度加深了对 IES-2 的理解,并对直觉饮食干预在普通人群中的应用产生了影响。
