The Preference for Intuition and Deliberation in Food Decision-Making Scale (E-PID) was developed to evaluate both intuitive and deliberative food decision-making within a single instrument. However, its psychometric properties have only been assessed among German-speaking participants. The main aim of the present study was to evaluate evidence of validity and reliability of the E-PID among 604 Brazilian adult women. Exploratory ( = 289) and confirmatory factor analyses ( = 315) were conducted to evaluate the factor structure of the E-PID. Convergent validity was assessed correlating the E-PID with measures of eating behaviors (Tree-Factor Eating Questionnaire-18), intuitive eating (Intuitive Eating Scale-2), and a measure of beliefs and attitudes towards food (Food-Life Questionnaire-SF). McDonald's Omega coefficient (ω) was used to test the internal consistency of the E-PID. Results from an exploratory and confirmatory factor analysis supported a two-factor structure with seven items. We found good internal consistency (McDonald's = 0.77-0.81). Furthermore, the E-PID demonstrated adequate convergent validity with measures of intuitive, restrictive, emotional and uncontrolled eating, and beliefs and attitudes towards food. Results support the use of the E-PID as a measure of intuition and deliberation in food decision-making among Brazilian adult women, expanding the literature on eating decision-making styles.
食物决策偏好量表（E-PID）旨在通过单一工具评估内隐和外显的食物决策。然而，其心理测量学特性仅在德语使用者中进行了评估。本研究的主要目的是评估 E-PID 在 604 名巴西成年女性中的有效性和可靠性证据。进行了探索性（n=289）和验证性因素分析（n=315），以评估 E-PID 的因素结构。通过与饮食行为量表（Tree-Factor Eating Questionnaire-18）、直觉饮食量表（Intuitive Eating Scale-2）和食物信念和态度量表（Food-Life Questionnaire-SF）进行相关性分析，评估了 E-PID 的聚合效度。使用 McDonald's Omega 系数（ω）检验 E-PID 的内部一致性。探索性和验证性因素分析的结果支持具有七个项目的两因素结构。我们发现了良好的内部一致性（McDonald's = 0.77-0.81）。此外，E-PID 与直觉、限制、情绪和失控饮食以及食物信念和态度的测量具有良好的聚合效度。结果支持在巴西成年女性中使用 E-PID 作为衡量食物决策内隐和外显的工具，扩展了关于饮食决策风格的文献。
