Personality traits and diet can be used to predict if a person is predisposed to disordered eating. Results of this study demonstrate a strong significant relationship between the personality trait of selflessness, diet group, and disordered eating. Vegans were most likely to display selflessness tendencies associated with disordered eating; however when selflessness was controlled for, vegans displayed substantially less disordered eating pathology than non-vegetarians.
To explore the relationship between diet group (non-vegetarian, semi-vegetarian, true-vegetarian, and vegan) and disordered eating while investigating to what extent personality trait of selflessness mediates the relationship between diet group and disordered eating.
Cross-sectional data from 634 Australian nonclinical women who completed a series of online questionnaires including measures of diet group, disordered eating, and selflessness were used to examine associations between diet, personality (selflessness), and disordered eating.
Selflessness was found to be a significant positive predictor of disordered eating. Results confirm that selflessness played a suppressing role in the relationship between the vegan diet group and disordered eating, when compared to non-vegetarians. Surprisingly, vegans displayed significantly less disordered eating than non-vegetarians and semi-vegetarians.
Results of the current study imply that the role of selflessness on disordered eating, when broken down across diet group, may be more complex than first thought. If replicated, these results suggest that targeted treatment of selflessness in different diet groups may improve treatment outcomes for disordered eating. Further research should explore why diet groups differ in terms of selflessness and how this impacts disordered eating.
个性特征和饮食可以用来预测一个人是否容易出现饮食失调。本研究的结果表明,无私的个性特征、饮食群体与饮食失调之间存在着强烈的显著关系。素食者最有可能表现出自私倾向与饮食失调有关;然而,当控制了无私时,素食者的饮食失调病理表现明显少于非素食者。
探讨饮食群体(非素食者、半素食者、纯素食者和素食者)与饮食失调之间的关系,同时调查无私个性特征在多大程度上调节饮食群体与饮食失调之间的关系。
使用来自 634 名澳大利亚非临床女性的横断面数据,她们完成了一系列在线问卷,包括饮食群体、饮食失调和无私个性特征的测量,以检查饮食、个性(无私)和饮食失调之间的关联。
发现无私是饮食失调的一个显著正向预测因子。结果证实,与非素食者相比,无私在素食者饮食群体与饮食失调之间的关系中起到了抑制作用。令人惊讶的是,素食者的饮食失调程度明显低于非素食者和半素食者。
本研究的结果表明,当按饮食群体细分时,无私对饮食失调的作用可能比最初想象的更复杂。如果得到复制,这些结果表明,针对不同饮食群体的无私进行有针对性的治疗可能会改善饮食失调的治疗效果。进一步的研究应该探索为什么饮食群体在无私方面存在差异,以及这如何影响饮食失调。
