Distinguishing between flexible and rigid cognitive restraint (CR) may be useful for understanding the role of CR in dietary behavior and weight status. This study aimed to translate and adapt the flexible and rigid CR scales to the French context and test their psychometric properties. Construct validity, internal consistency, and test-retest reliability were examined in a sample of 620 individuals. Confirmatory factor analysis of the scales found a two-factor structure (flexible CR: 12 items; rigid CR: 15 items) that provided a good fit and supported the initial solution ( = 584.7, df = 322, CFI = 0.96, RMSEA = 0.052 [0.045, 0.059], TLI = 0.95). Higher flexible and rigid CR were associated with higher CR overall, emotional eating (TFEQ-R21) and eating disorders (SCOFF), and lower intuitive eating (IES-2). In addition, higher flexible CR was associated with lower impulsivity (BIS-11) while higher rigid CR was associated with higher uncontrolled eating (TFEQ-R21) and lower self-esteem (RSES), satisfaction with life (SWLS), and optimism (LOT-R). Flexible and rigid CR internal consistency was satisfactory (McDonald ω = 0.77 and 0.74, respectively) and test-retest reliability was good (ICC = 0.81 and 0.79, respectively). This study validated a flexible and rigid CR tool in a French population and confirmed that these two types of CR represent distinct eating behaviors.
区分灵活和僵化的认知约束（CR）可能有助于理解 CR 在饮食行为和体重状况中的作用。本研究旨在将灵活和僵化的 CR 量表翻译并改编为法语环境，并检验其心理测量特性。在 620 名个体的样本中检查了构念效度、内部一致性和重测信度。对量表的验证性因子分析发现了两因素结构（灵活 CR：12 项；僵化 CR：15 项），提供了良好的拟合度并支持初始解决方案（=584.7，df=322，CFI=0.96，RMSEA=0.052[0.045，0.059]，TLI=0.95）。较高的灵活和僵化 CR 与更高的 CR 总体水平、情绪性进食（TFEQ-R21）和饮食失调（SCOFF）以及较低的直觉性进食（IES-2）相关。此外，较高的灵活 CR 与较低的冲动性（BIS-11）相关，而较高的僵化 CR 与较高的失控性进食（TFEQ-R21）和较低的自尊（RSES）、生活满意度（SWLS）和乐观主义（LOT-R）相关。灵活和僵化 CR 的内部一致性是令人满意的（McDonald ω 分别为 0.77 和 0.74），重测信度良好（ICC 分别为 0.81 和 0.79）。本研究在法国人群中验证了灵活和僵化的 CR 工具，并证实这两种类型的 CR 代表了不同的进食行为。
