分手，即恋爱关系终止，常常会引发个体一系列强烈的心理反应，如悲伤、自责、反刍思维、对前任伴侣的渴望、抑郁、焦虑和失眠等，这一系列与哀伤相似的负面情绪体验被称为“分手痛苦”。分手痛苦给个体带来心理健康风险，影响社会功能。这种影响对处于成年早期的大学生群体尤为显著。处在这一发展阶段的大学生更频繁地参与恋爱关系，因此更频繁地经历分手。此外大学生应对分手痛苦的能力和策略尚不成熟，分手痛苦威胁他们的心理健康，并对他们未来的关系模式和福祉产生深远的影响。因此，本研究旨在针对处于成年早期的中国大学生，深入研究分手痛苦的测量、重要相关因素以及干预方案，为心理健康领域提供新的见解，并为设计更有效的心理干预措施和提升大学生心理健康服务质量提供科学依据。本研究分为三个部分：研究一：修订中文版分手痛苦量表，并在中国大学生群体中验证其信效度和适用性。通过修订该量表，旨在提供一种可靠的测量工具，将分手痛苦程度与一般负面情绪反应区分开来，为未来心理学研究和心理健康实践中的评估和理解分手痛苦提供重要工具，并为开发更具适切性的心理干预措施提供坚实的理论基础。研究二：探索个体情绪调节策略和亲密关系效能感对分手痛苦影响的机制，特别关注亲密关系效能感的中介作用。研究三：本研究对已有实证研究支持的国外大学生亲密关系教育项目进行本土化改编，开发出一种适用于中国大学生的分手干预方案，旨在缓解分手痛苦并改善心理健康主要研究结果：分手痛苦量表中文版在中国大学生样本中表现出良好的心理测量特性。情绪调节策略对分手痛苦水平有显著影响，亲密关系效能感在两者之间起到部分中介作用。本土化改编的分手应对工作坊能有效减轻大学生的分手痛苦，增强亲密关系效能感，改善情绪调节策略，提升心理健康。本研究的结果不仅丰富了心理健康领域对分手痛苦的认识，还提供了有效的干预措施，帮助大学生更好地应对分手带来的心理挑战，为经历分手痛苦的大学生提供实用的支持和策略，促进心理恢复和个人成长。

The end of a romantic relationship, commonly known as a breakup, often triggers a series of intense negative psychological reactions such as rumination, depression, anxiety, and insomnia, or emotions similar to grief. This range of negative emotional experiences is referred to as "breakup distress," which not only poses risks to mental health but also affects an individual's social functioning. This impact is particularly pronounced among college students in early adulthood. At this developmental stage, college students frequently engage in interpersonal explorations, including romantic relationships, and thus experience breakups more often. Due to their immature coping abilities and strategies, breakup distress can pose severe mental health risks for college students and significantly affect their future relationship patterns.This study aims to deeply investigate the measurement, key factors, and intervention strategies for "breakup distress" among Chinese college students in early adulthood. The goal is to provide more comprehensive insights into the field of mental health, to offer a scientific basis for designing more effective psychological interventions, and to improve the quality of mental health services for college students. This study also proposes innovative strategies to address the limitations and challenges of current psychological interventions.The study is divided into three parts:Study 1 revises the Chinese version of the Breakup Distress Scale and validates its precision and applicability among Chinese college students. The purpose of revising this scale is to provide a reliable measurement tool that distinguishes the degree of breakup distress from general emotional responses. This tool will serve as an important instrument for future psychological research and mental health practice in assessing and understanding breakup distress, and will provide a solid theoretical foundation for developing targeted psychological interventions. Study 2 explores the mechanisms by which individual emotion regulation strategies and romantic self-efficacy influence breakup distress, with a particular focus on the mediating role of romantic self-efficacy in this relationship. Study 3 adapts an empirically supported romantic relationship education program originally developed for university students abroad, localizing it to create a breakup intervention tailored for Chinese university students. The intervention aims to alleviate breakup distress and enhance psychological well-being.This study found that the Chinese version of the Breakup Distress Scale demonstrated strong psychometric properties in a sample of Chinese university students. Emotion regulation strategies were found to significantly affect the level of breakup distress, with romantic self-efficacy serving as a partial mediator in this relationship. The localized adaptation of the breakup coping workshop, as an intervention, was effective in alleviating breakup distress, enhancing emotion regulation strategies, improving romantic self-efficacy, and promoting psychological well-being among university students.The results of this study not only enrich the understanding of breakup distress in the field of mental health but also provide effective intervention measures to help college students better cope with the psychological challenges brought about by breakups. Through this research, we hope to offer practical support and strategies for college students experiencing breakup distress, thereby promoting their psychological recovery and personal growth.
