The aim of this study was to examine the necessity of early intervention for students with potential bulimia by investigating how the eating attitudes of college students change and examining the relation between bulimic symptoms and depressive symptoms or the ability to cope with stress.
The study participants were students who entered Hiroshima University in 2014. This study was conducted at two time points: Time-1 in 2014 and Time-2 in 2017. The Eating Attitudes Test-26 (EAT-26), Bulimic Inventory Test, Edinburgh (BITE), Beck Depression Inventory-II (BDI-II), and Coping Inventory for Stressful Situations (CISS) were administered at Times 1 and 2, and the responses were compared between the time points. Next, we compared the BDI-II scores of the BITE improved and worsened groups. In addition, we divided the participants into a clinical group, subthreshold group, and healthy group based on the BITE score at Time-1to compared their depressive symptoms and the ability to cope with stress.
Significantly higher BITE and BDI-II scores were recorded for both males and females at Time-2 than at Time-1. The BDI-II score at Time-1 was significantly higher in the BITE worsened group than in the BITE improved group. The BDI-II scores at Time-1 were significantly higher for both males and females in the subthreshold group than in the healthy group. Furthermore, significantly higher CISS-T and CISS-E scores were recorded at Time-1 for females in the subthreshold group than for females in the healthy group.
Based on these results, intervention for students the subthreshold group is important, and the key to intervention may be to address not only eating behaviors but also depressive symptoms and stress coping.

本研究旨在通过调查大学生饮食态度的变化，以及暴食症状与抑郁症状或应对压力能力之间的关系，探讨对有潜在暴食症学生进行早期干预的必要性。
研究参与者为2014年进入广岛大学的学生。本研究在两个时间点进行：2014年的时间点1和2017年的时间点2。在时间点1和2分别进行进食态度测试-26（EAT-26）、爱丁堡暴食量表（BITE）、贝克抑郁量表第二版（BDI-II）和应激情境应对量表（CISS），并比较两个时间点的回答。接下来，我们比较了BITE得分改善组和恶化组的BDI-II得分。此外，我们根据时间点1的BITE得分将参与者分为临床组、阈下组和健康组，以比较他们的抑郁症状和应对压力的能力。
在时间点2，男性和女性的BITE和BDI-II得分均显著高于时间点1。BITE恶化组在时间点1的BDI-II得分显著高于BITE改善组。阈下组男性和女性在时间点1的BDI-II得分均显著高于健康组。此外，阈下组女性在时间点1的CISS-T和CISS-E得分显著高于健康组女性。
基于这些结果，对阈下组学生进行干预很重要，干预的关键可能不仅要解决饮食行为问题，还要解决抑郁症状和压力应对问题。
