在婚姻和恋爱关系中，出轨是场常见的灾难。个体在经历被出轨的过程中会产生包括抑郁情绪在内的很多负面情绪，引发情绪失调。情绪失调的混乱状态会进一步加重被出轨个体的痛苦感受，抑郁水平显著提高。目前针对出轨群体的干预研究主要集中在修复伴侣关系，但越来越多人相比关系修复更专注于自身情绪状态的恢复。因此，本研究提出关注被出轨个体的情绪改善，而非伴侣关系的修复。有效的情绪调节策略可以改善抑郁情绪。Gross情绪调节理论提出最常用的两种情绪调节策略分别是认知重评（cognitive reappraisal）和表达抑制（expression suppression）。中国文化对被出轨存在“绿帽羞耻”的观念，可能更容易激发被出轨方对表达抑制的使用。但国外的实证研究证明随着表达抑制的使用增多抑郁情绪也会增多。因此，为了保护被出轨个体的心理健康，有必要关注情绪调节，并研究如何干预表达抑制。与其他心理治疗方法相比，情绪聚焦疗法（Emotionally Focused Therapy, EFT）特别关注情绪调节和情绪表达，因此可能有助于干预表达抑制，帮助来访者减少表达抑制的使用频率。在此背景下提出本研究，研究分为以下两部分进行：
研究一采用方便抽样法通过网络招募被出轨个体，最终得到149名符合条件的被试（女111人、男38人）。使用问卷法对这些被试进行施测，施测问卷包括《贝克抑郁自评量表》和《情绪调节问卷-表达抑制子问卷》。研究结果发现被出轨个体的表达抑制能够正向预测抑郁情绪，这说明减少表达抑制有助于改善个体抑郁情绪。
研究二使用个案干预法对一位被出轨的已婚女性进行情绪聚焦疗法个案咨询。来访三个月前发现丈夫出轨，但压抑自身情绪体验并克制对丈夫和其他人的情绪表达，产生明显抑郁情绪。咨询师对此进行一周一次，一次50分钟，总共9次咨询的情绪聚焦疗法的咨询干预，分别在咨询前、咨询后和咨询结束一个月，使用《贝克抑郁自评量表》、《情绪调节问卷》、《积极情绪消极情绪问卷》对来访进行测量。结果显示，针对被出轨个体的情绪聚焦疗法干预可以有效减少表达抑制的使用频率，增加积极消极情绪情感的表达，从而改善来访的抑郁情绪，并且预后效果良好。
总的来说，研究发现被出轨个体的表达抑制能够正向预测抑郁情绪，使用情绪聚焦疗法干预被出轨个体的表达抑制，可以有效改善抑郁情绪。从理论意义上，本研究关注被出轨方的情绪，而不同于以往研究关注于对伴侣双方关系修复；拓展表达抑制的干预成分。从现实意义上，增强被出轨个体对中国传统封建文化促进表达抑制使用的自我觉察，并提供临床咨询的干预方案参考。

Infidelity is a common disaster in marriage and romantic relationships. Many complex negative emotions, including depressive mood, will be generated in the process of experiencing about infidelity, leading to emotional disorder.The chaotic state of emotional disorder will further aggravate the pain of individual being cheated on, and the level of depressive mood will significantly increase. Current intervention studies for individuals being cheated on are mainly focused on repairing partnerships. However, more and more people focus on the recovery of their emotional state rather than relationship repair. Therefore, this study proposes to focus on individuals being cheated on rather than the partner, focusing on improving their depressive mood. Effective emotion regulation strategies can improve depressive mood. Gross emotion regulation theory proposes that the two most commonly used emotion regulation strategies are cognitive reappraisal and expression suppression. The "green hat" in Chinese culture may inspire the use of expression suppression. Empirical studies abroad have shown that depressive mood increases with the increase of expression suppression. Therefore, in order to protect the mental health of individuals being cheated on, it is necessary to pay attention to emotional regulation and how to intervene in the frequency of expression suppression. In this context, this research is proposed, which is divided into the following two parts:
In Study 1, 149 eligible participants (111 female and 38 male) were recruited through the Internet using convenient sampling method. Questionnaires were used to measure these subjects, including Beck Depression Index and Emotion Regulation Questionnaire. The results showed that expression suppression in individuals being cheated on can positively predict depressive mood.This suggests that reducing expression suppression can improve individual depressive mood.
In Study 2, a married woman being cheated on was given Emotionally Focused Therapy counseling.Three months ago, she found her husband and another woman derailed, but she suppressed her emotional experience and restrained her emotional expression to her husband and others, resulting in significant depressive mood. The researcher conducted a weekly, 50-minute counseling with Emotionally Focused Therapy. It was evaluated and tracked using Beck Depression Index, Emotion Regulation Questionnaire and The Positive and Negative Affect Scales before, after, and one month after the consultation. The results showed that Emotionally Focused Therapy intervention for individuals being cheated on can effectively reduce the frequency of expression suppression, increase the experience and emotional expression, and improve the depressive mood.
In general, the results showed that expression suppression in individuals being cheated on can positively predict depressive mood, and Emotionally Focused Therapy intervention for individuals being cheated on can effectively reduce the frequency of expression suppression and improve the depressive mood. 
In theory, the research focused on the emotions of individuals being cheated on, unlike previous studies that focused on repairing the relationship. the research expanded intervention components for expression suppression. In practice, the research aims to enhance the self-awareness of the cheated individuals on the use of the promotion expression suppression of Chinese traditional feudal culture, and provide reference for the intervention plan of clinical consultation.
