PURPOSE
General and eating disorder (ED)-specific ruminations have been identified as key factors that may contribute to eating pathology. Positive beliefs about rumination (e.g., "Ruminating helps me to prevent future mistakes") may impact this association. However, the effect of positive beliefs about rumination on the links between rumination and ED symptom severity has not been investigated. This study sought to clarify relations between rumination and ED symptom severity and to evaluate the potential moderating effect of positive beliefs about rumination on these associations.
METHODS
During a laboratory visit, undergraduate participants (N = 473, M = 18.90 ± 2.27, M = 23.45 kg/m ± 4.31, 54.8% female) completed an online battery of questionnaires assessing general and ED-specific ruminative processes (e.g., brooding, reflection), positive beliefs about rumination, and global ED symptoms. Hierarchical multiple regression analyses assessed the unique contributions of specific ruminative processes, and the moderating effect of positive beliefs on associations between ruminative processes and ED symptom severity.
RESULTS
Hierarchical multiple regression results suggest that, after controlling for gender and BMI, ED-specific brooding, b = 1.32, SE = 0.13, β = 0.46, p < 0.0001, and reflection, b = 1.44, SE = 0.33, β = 0.19, p < 0.0001, accounted for unique variance in ED symptom severity. Moderation model results indicate that, at low levels of general reflection, b = - 0.06, SE = 0.02, β = - 0.51, p = 0.003, and ED-specific reflection, b = - 0.15, SE = 0.03, β = - 0.59, p < 0.0001, increased positive beliefs about rumination were associated with greater ED symptom severity.
CONCLUSION
Findings suggest ED-specific rumination accounts for ED symptom severity above and beyond general rumination, and that rumination-related expectancies influence the association between reflection and ED symptom severity.
LEVEL OF EVIDENCE
Level III, evidence obtained from a well-designed cohort study.
目的
普遍存在的和特定于进食障碍（ED）的反刍思维被认为是可能导致进食障碍的关键因素。对反刍的积极信念（例如，“反刍有助于我防止未来犯错误”）可能会影响这种关联。然而，关于反刍的积极信念对反刍与 ED 症状严重程度之间的联系的影响尚未得到研究。本研究旨在阐明反刍与 ED 症状严重程度之间的关系，并评估关于反刍的积极信念对这些关联的潜在调节作用。
方法
在实验室访问期间，本科参与者（N=473，M=18.90±2.27，M=23.45kg/m±4.31，54.8%女性）完成了在线问卷的电池，评估了普遍的和特定于 ED 的反刍过程（例如，沉思，反思），关于反刍的积极信念和整体 ED 症状。分层多元回归分析评估了特定反刍过程的独特贡献，以及积极信念对反刍过程与 ED 症状严重程度之间关联的调节作用。
结果
分层多元回归结果表明，在控制性别和 BMI 后，ED 特异性的沉思，b=1.32，SE=0.13，β=0.46，p<0.0001，和反射，b=1.44，SE=0.33，β=0.19，p<0.0001，对 ED 症状严重程度有独特的解释。调节模型结果表明，在普遍反思水平较低的情况下，b=-0.06，SE=0.02，β=-0.51，p=0.003，和 ED 特异性反射，b=-0.15，SE=0.03，β=-0.59，p<0.0001，增加关于反刍的积极信念与更大的 ED 症状严重程度有关。
结论
研究结果表明，ED 特异性反刍可解释 ED 症状严重程度，而不仅仅是普遍的反刍，并且与反刍相关的预期会影响反射与 ED 症状严重程度之间的关系。
