本研究探讨大学生强迫症状与抑郁症状亚临床共症现象，及童年创伤经历和情绪调节困难在其中作用。研究采用横断面设计和问卷调查，使用网络分析、中介模型等方法，探索大学生童年创伤经历各子类型、情绪调节困难各维度和临床症状间网络结构，并根据其桥梁节点进一步建立了有调节的中介模型。

研究一通过比较强迫症状组和无强迫症状组的人口学信息、临床症状、童 年创伤经历和情绪调节困难指标，探索强迫症状组各指标特征。结果显示，强 迫 症 状 组 抑 郁 症 状 （F=11745.518, p<0.001）、 童 年 创 伤 经 历 （F=116.418, p<0.001）和情绪调节困难（F=707.574, p<0.001）及后两量表各维度得分（p<0.001）都显著高于无强迫症状组。

研究二利用网络分析技术，构建了强迫症状共症抑郁症状者强迫症状、抑郁症状、童年创伤各子类型及情绪调节困难各子维度的网络结构模型，同时建立全体被试网络结构模型以进行对比。结果显示，与全体被试网络结构模型不同，共症组网络模型中冲动控制困难这一子维度具有重要桥梁作用。

研究三首先通过相关性分析发现共症组中强迫症状严重程度与抑郁症状严重程度（r=0.19, p<0.05）和情绪调节困难量表下的冲动控制困难子维度（r =0.29, p<0.01）显著相关；冲动控制困难与抑郁症状（r =0.34, p<0.01）显著相关。随后建立了以童年创伤经历为调节变量、冲动控制困难为中介变量、强迫症状为自变量及抑郁症状为因变量的有调节的中介模型，经验证拟合良好。

综上所述，本研究利用网络分析技术和有调节的中介模型，探索了童年创伤经历和情绪调节困难在强迫症状抑郁症状共症现象中的作用，得出以下结论： （1）大学生的强迫症状评分越高，其抑郁症状评分、情绪调节困难各子维度及 总分及童年创伤经历的各子类型及总分均越高，这表明大学生强迫症状与其抑 郁症状、情绪调节困难及童年创伤经历显著相关。（2）在共症组网络结构模型 及全体被试网络结构模型中，有限的情绪调节策略和情感虐待起到重要桥梁作 用，这提示有效的情绪调节策略和情感虐待的预防在减少强迫和抑郁症状及两 者共症的发生中具有重要意义。（3）仅在共症组网络结构模型中，冲动控制困 难子维度起到了重要的桥梁作用，这显示出冲动控制困难在强迫症状抑郁症状 共症群体中的独特影响。（4）共症组中强迫症状、抑郁症状、情绪调节困难之 间存在显著相关，这表明情绪调节困难可能是连接强迫症状和抑郁症状的重要 因素。（5）冲动控制困难在强迫症状和抑郁症状之间起到中介作用，童年创伤 经历在这一模型中显著调节了强迫症状与抑郁症状之间的关系。

以上发现不仅加深了我们对强迫症状抑郁症状共症机制的理解，还为临床治疗提供了具体干预目标。例如，通过对冲动控制和童年创伤经历针对性干预，可以更有效地缓解共症症状。本研究对心理健康评估和干预具有一定应用价值，对临床工作者制定干预方案具有一定理论指导，对提高治疗效果和患者整体心 理健康水平具有一定意义。

This study explores the subclinical comorbidity of obsessive-compulsive symptoms and depressive symptoms in college students, and the role of childhood traumatic experiences and difficulties in emotion regulation. The study adopted a crosssectional design and questionnaire survey and used methods such as network analysis and mediation models to explore the network structure among subtypes of childhood traumatic experiences, dimensions of emotion regulation difficulties and clinical symptoms among college students, and further established a moderated network structure based on their bridge nodes. mediation model.

Study 1 explores the characteristics of each indicator in the obsessive-compulsive symptom group by comparing the demographic information, clinical symptoms, childhood traumatic experiences and emotional regulation difficulty indicators between the obsessive-compulsive symptom group and the non-obsessive-compulsive symptom group. The results showed that in the obsessive-compulsive symptom group, depressive symptoms (F=11745.518, p＜0.001 )，childhood traumatic experiences (F=116.418, p＜0.001 ) and difficulties in emotional regulation(F=707.574, p＜0.001 ) and the dimensions of the latter two scales The scores (p＜0.001 ) were significantly higher than those of the group without obsessive-compulsive symptoms.

Study 2 used network analysis technology to construct a network structure model of obsessive-compulsive symptoms, depressive symptoms, childhood trauma subtypes, and emotion regulation difficulties in patients with obsessive-compulsive symptoms and depressive symptoms. At the same time, a network structure model of all subjects was established for comparison. The results show that, unlike the network structure model of all subjects, the sub-dimension of impulse control difficulties in the network model of the comorbid group plays an important bridging role.

Study 3 first used correlation analysis to find that the severity of obsessivecompulsive symptoms and the severity of depressive symptoms in the comorbid group (r=0.19, p< 0.05) and the sub-dimension of impulse control difficulties under the Emotion Regulation Difficulties Scale (r =0.29, p< 0.01) was significantly correlated; impulse control difficulties were significantly correlated with depressive symptoms (r =0.34,p< 0.01) Subsequently, a moderated mediation model was established with childhood traumatic experience as the moderating variable, impulse control difficulties as the mediating variable, obsessive-compulsive symptoms as the independent variable and depressive symptoms as the dependent variable, and it was verified that the fit was good.

In summary, this study used network analysis techniques and moderated mediation models to explore the role of childhood traumatic experiences and emotion regulation difficulties in the comorbidity of obsessive-compulsive symptoms and depressive symptoms, and reached the following conclusions: (1) Obsessive-compulsive disorder in college students The higher the symptom score, the higher the depressive symptom score, the sub-dimensions and total scores of emotion regulation difficulties, and the subtypes and total scores of childhood traumatic experiences. This shows that obsessive-compulsive symptoms in college students are related to their depressive symptoms, emotion regulation difficulties, and childhood traumatic experiences. Significant correlation. (2) In the network structure model of the comorbid group and the network structure model of all subjects, limited emotion regulation strategies and emotional abuse play an important bridging role, which suggests that effective emotion regulation strategies and the prevention of emotional abuse play an important role in reducing obsessive-compulsiveness and depression. It is of great significance in the occurrence of symptoms and co-morbidities of both. (3) Only in the network structure model of the comorbid group, the sub-dimension of impulse control difficulties plays an important bridging role, which shows the unique impact of impulse control difficulties in the comorbid group of obsessive-compulsive symptoms and depressive symptoms. (4) There is a significant correlation between obsessive-compulsive symptoms, depressive symptoms, and emotional regulation difficulties in the comorbidity group, which indicates that emotional regulation difficulties may be an important factor connecting obsessive-compulsive symptoms and depressive symptoms. (5) Impulse control difficulties play a mediating role between obsessive-compulsive symptoms and depressive symptoms, and childhood traumatic experience significantly mediates the relationship between obsessive-compulsive symptoms and depressive symptoms in this model.

The above findings not only deepen our understanding of the comorbid mechanisms of obsessive-compulsive symptoms and depressive symptoms, but also provide specific intervention targets for clinical treatment. For example, comorbid symptoms may be more effectively alleviated through targeted interventions on impulse control and childhood traumatic experiences. This study has certain application value for mental health assessment and intervention, has certain theoretical guidance for clinical workers in formulating intervention plans, and has certain significance for improving treatment effects and patients' overall mental health level.
