Considering the prevalence of ED-related prodromal symptoms among higher education students (making them a population at risk for developing EDs), the main goals of this study were to conduct a network analysis in a college sample and to explore multivariate dependencies between a selection of empirically informed variables of interest to eating psychopathology, namely difficulties in emotion regulation and psychological processes (e.g., interoceptive awareness, self-compassion, self-criticism, mindfulness, and experiential avoidance).
The sample included 294 college students ( = 21.4, = 5.0; = 22.4, = 3.7). A Gaussian graphical network model was estimated to visualize interactions among the studied variables and to assess their centrality in terms of betweenness, closeness, strength, and expected influence.
A network system with 21 nodes was estimated (sparsity = 0.52). Nodes assessing disordered eating symptoms displayed the strongest correlation coefficients with nodes assessing dimensions of interoceptive awareness: eating concerns and not-distracting ( = -0.11), shape concerns and trusting ( = -0.16), and weight concerns and trusting ( = -0.10). Self-compassion was the node with the highest betweenness (SELFCS = 2.27) and closeness centrality (SELFCS = 1.70). The nodes with the highest strength centrality were strategies (DERS = 1.91) and shape concerns (EDE-Q = 1.51).
In this network model conducted in a college sample, eating-related symptoms were mainly associated with dimensions of interoceptive awareness. Also, the lack of effective strategies to regulate emotions, shape concerns, and self-compassion stood out as central nodes in the network model. The results suggest that addressing these variables may be promising in disrupting network systems marked by the presence of prodromal eating psychopathology symptoms in at-risk populations (e.g., college students).
鉴于高等教育学生中存在与 ED 相关的前驱症状(使他们成为易患 ED 的人群),本研究的主要目标是在大学生样本中进行网络分析,并探索与进食心理病理学相关的一系列经验性变量之间的多元相关性,即情绪调节困难和心理过程(例如,内感受意识、自我同情、自我批判、正念和经验回避)。
该样本包括 294 名大学生( = 21.4, = 5.0; = 22.4, = 3.7)。估计了一个高斯图形网络模型,以可视化研究变量之间的相互作用,并根据中间度、接近度、强度和预期影响评估它们的中心性。
估计了一个具有 21 个节点的网络系统(稀疏度 = 0.52)。评估饮食失调症状的节点与评估内感受意识维度的节点显示出最强的相关系数:进食担忧和不分散注意力( = -0.11)、体型担忧和信任( = -0.16)以及体重担忧和信任( = -0.10)。自我同情是具有最高中间度(SELFCS = 2.27)和接近度中心性(SELFCS = 1.70)的节点。具有最高强度中心性的节点是策略(DERS = 1.91)和体型担忧(EDE-Q = 1.51)。
在这个在大学生样本中进行的网络模型中,与饮食相关的症状主要与内感受意识维度相关。此外,缺乏有效的情绪调节策略、体型担忧和自我同情作为网络模型中的中心节点突出。结果表明,在高危人群(例如大学生)中,解决这些变量可能是破坏存在前驱进食心理病理学症状的网络系统的有希望的方法。
