Emotion dysregulation and negative self-directed behaviors are key characteristics of eating disorders (EDs), but their interaction in relation to ED psychopathology is insufficiently explored, and empirically robust and clinically relevant models are needed.
This study examined whether the association between emotion dysregulation and ED psychopathology was mediated by different negative self-directed behaviors in 999 ED patients divided into two sub-samples based on absence or presence of objective binge-eating episodes (OBE). Several simple and extended mediation models were examined using the Difficulties in Emotion Regulation Scale (DERS) as independent variable, the Structural Analysis of Social Behavior (SASB) as mediator, and the Eating Disorder Examination Questionnaire (EDE-Q) as dependent variable.
An associational pathway was found where higher emotion dysregulation was associated with more negative self-directed behaviors, which in turn was associated with higher ED psychopathology. Self-directed behaviors of importance differed between patient groups. In participants without OBE, lower self-love and higher self-attack were influential, whereas in participants with OBE, lower self-affirmation and higher self-blame were influential.
Self-directed behaviors may help to explain the association between emotion dysregulation and ED psychopathology. Our findings have both theoretical and clinical implications that are pathology-specific. Addressing specific self-directed behaviors could be an important way of helping patients deal with their emotions in relation to ED psychopathology.
情绪调节障碍和消极的自我导向行为是饮食失调(EDs)的关键特征,但它们在ED精神病理学方面的相互作用尚未得到充分探索,因此需要实证稳健且具有临床相关性的模型。
本研究调查了在999名ED患者中,情绪调节障碍与ED精神病理学之间的关联是否由不同的消极自我导向行为介导。这些患者根据是否存在客观暴饮暴食发作(OBE)被分为两个子样本。使用情绪调节困难量表(DERS)作为自变量、社会行为结构分析(SASB)作为中介变量、饮食失调检查问卷(EDE-Q)作为因变量,检验了几个简单和扩展的中介模型。
发现了一条关联路径,即较高的情绪调节障碍与更多消极的自我导向行为相关,而这又与较高的ED精神病理学相关。不同患者组中重要的自我导向行为有所不同。在没有OBE的参与者中,较低的自爱和较高的自我攻击有影响,而在有OBE的参与者中,较低的自我肯定和较高的自责有影响。
自我导向行为可能有助于解释情绪调节障碍与ED精神病理学之间的关联。我们的研究结果具有针对特定病理学的理论和临床意义。解决特定的自我导向行为可能是帮助患者处理与ED精神病理学相关情绪的重要方式。
