PURPOSE
Cognitive rumination is a transdiagnostic construct that has been increasingly studied in the context of eating disorders (EDs). While this literature has consistently linked trait-level general and ED-specific forms of rumination to ED psychopathology, it is not clear whether trait-level measures are independently related to symptoms in daily life. Therefore, the present study used ecological momentary assessment (EMA) to assess the ecological validity of trait measures of general rumination and ED-specific rumination, and assess the degree to which ruminative brooding and reflection were differentially related to relevant momentary affective, cognitive, and behavioral processes.
METHODS
Forty women completed baseline measures (Ruminative Response Scale [RRS] and Ruminative Response Scale for Eating Disorders [RRSED]) followed by a 10-day EMA protocol.
RESULTS
Generalized estimating equations indicated trait-level ED-specific rumination was related to momentary general and ED-specific rumination, and trait-level general and ED-specific rumination were related to momentary affect and concentration difficulties. Trait-level general rumination was related to momentary self-discrepancy, while higher trait-level ED-specific rumination was related to greater loss of control eating, overeating, and body dissatisfaction. Lastly, trait levels of ruminative brooding, compared to reflection, were more consistently related to maladaptive momentary symptoms (i.e., general rumination, negative affect, concentration problems, body dissatisfaction).
CONCLUSION
Together these findings support the ecological validity of the RRSED and identify shared and unique momentary correlates of the RRS and RRSED. Results also highlight the importance of measuring and addressing trait- and state-level ruminative processes that are both general and specific to ED psychopathology in research and clinical work.
LEVEL OF EVIDENCE
Level V, observational descriptive study.
目的
认知反刍是一种跨诊断的概念，在饮食失调（ED）的背景下受到越来越多的研究。虽然该文献一直将特质水平的一般反刍形式和特定于饮食失调的反刍形式与饮食失调的精神病理学联系起来，但尚不清楚特质水平的测量是否与日常生活中的症状独立相关。因此，本研究采用生态瞬时评估（EMA）来评估一般反刍和特定于饮食失调的反刍特质测量的生态效度，并评估反刍沉思和反思与相关瞬时情感、认知和行为过程的差异相关程度。
方法
40名女性完成了基线测量（反刍反应量表[RRS]和饮食失调反刍反应量表[RRSED]），随后进行了为期10天的EMA方案。
结果
广义估计方程表明，特质水平的特定于饮食失调的反刍与瞬时一般反刍和特定于饮食失调的反刍相关，特质水平的一般反刍和特定于饮食失调的反刍与瞬时情感和注意力困难相关。特质水平的一般反刍与瞬时自我差异相关，而较高特质水平的特定于饮食失调的反刍与更大的失控进食、暴饮暴食和身体不满相关。最后，与反思相比，反刍沉思的特质水平与适应不良的瞬时症状（即一般反刍、消极情绪、注意力问题、身体不满）更一致相关。
结论
这些发现共同支持了RRSED的生态效度，并确定了RRS和RRSED的共同和独特的瞬时相关因素。结果还强调了在研究和临床工作中测量和解决饮食失调精神病理学中一般和特定的特质和状态水平反刍过程的重要性。
