Abstract
Objective: Global emotion dysregulation mediates the relationship between child maltreatment and severe depressive symptoms; however, there is a lack of research on maladaptive personality traits and their contribution to individual differences in global emotion dysregulation within this conceptual model. The present study tested a preliminary serial mediation model where maladaptive personality traits and global emotion dysregulation mediate the relationship between child maltreatment and severe depressive symptoms.
Method: A total of 200 patients with mood disorders (Mage = 36.5 years; 54% females) were assessed for maladaptive personality traits (Personality Inventory for Diagnostic and Statistical Manual of Mental Disorders [5th ed.] Brief Form), global emotion dysregulation (Difficulties in Emotion Regulation Scale-Short), childhood trauma (Childhood Trauma Questionnaire), and depressive symptoms (Patient Health Questionnaire-9).
Results: Ordinary least squares regression and partial least squares-structural equation modeling revealed a consistent and significant indirect effect of child maltreatment on severe depressive symptoms through negative affectivity, detachment, psychoticism, and global emotion dysregulation. Among child maltreatment types, only emotional abuse had a significant indirect effect on severe depressive symptoms through maladaptive personality traits and global emotion dysregulation, b = 0.50, SE = 0.09, 95% confidence intervals [0.326, 0.694] after controlling for age, gender, and remaining types of child maltreatment.
Conclusions: Findings support the view that maladaptive personality traits shed important insights on individual differences in global emotion dysregulation, and this information could aid clinical formulation and treatment of childhood adversity-related psychopathology.

研究目的总体情绪失调是儿童虐待与严重抑郁症状之间关系的中介；然而，在这一概念模型中，缺乏对适应不良型人格特质及其对总体情绪失调个体差异贡献的研究。本研究测试了一个初步的序列中介模型，即适应不良型人格特质和整体情绪失调在儿童虐待和严重抑郁症状之间的关系中起中介作用：对200名情绪障碍患者（年龄=36.5岁；54%为女性）进行了适应不良人格特质（《精神疾病诊断与统计手册》[第5版]简表人格量表）、整体情绪失调（情绪调节困难量表-简表）、童年创伤（童年创伤问卷）和抑郁症状（患者健康问卷-9）的评估：结果：普通最小二乘法回归和偏最小二乘法-结构方程模型显示，儿童虐待通过负性情感、疏离、精神病性和全面情绪失调对严重抑郁症状产生了一致且显著的间接影响。在儿童虐待类型中，只有情感虐待通过适应不良人格特质和整体情绪失调对严重抑郁症状有显著的间接影响，在控制了年龄、性别和其他儿童虐待类型后，b = 0.50，SE = 0.09，95% 置信区间[0.326，0.694]：研究结果支持这样一种观点，即适应不良型人格特质对整体情绪失调的个体差异具有重要的启示作用，这些信息有助于临床制定和治疗与儿童逆境相关的精神病理学。(PsycInfo Database Record (c) 2024 APA, all rights reserved）。
