Background

Posttraumatic stress disorder (PTSD) and major depressive disorder (MDD) co-occur at high rates and greater disorder severity. Studies examining the contributions of specific emotion regulation (ER) processes and negative affect (NA) to PTSD and MDD co-occurrence are scarce. This study investigated a transdiagnostic understanding of the nature of PTSD and MDD co-occurrence by examining the roles of NA, ER processes, and negative mood regulation (NMR) expectancies in PTSD and MDD in relation to trauma.

Methods

Structural equation modeling was used to examine the roles of emotionality, PTSD, and MDD constructs in 200 individuals with primary PTSD.

Results

ER processes fully mediated the relationships between NA and PTSD (β = .40, p < .001) and MDD (β = .48, p < .001), and NMR expectancies and PTSD (β = −.31, p < .001) and MDD (β = −.37, p < .001).

Conclusions

NA and NMR expectancies exert their effects on PTSD and MDD almost entirely through ER processes. ER appears to be a transdiagnostic process, partly accounting for the co-occurrence between PTSD and MDD. Co-occurrence models could benefit by incorporating ER processes to inform diagnostic classification and criteria and clinical intervention improved by specifically targeting ER processes.

经诊断的情绪调节过程解释了情绪相关因素如何影响与创伤相关的同时发生的PTSD和MDD

背景

创伤后应激障碍（PTSD）和重度抑郁症（MDD）并发且发病率更高。缺乏研究特定情绪调节（ER）过程和负面影响（NA）对PTSD和MDD共现的贡献的研究。这项研究通过检查NA，ER过程以及与创伤相关的PTSD和MDD的不良情绪调节（NMR）预期的作用，研究了对PTSD和MDD并发的自然诊断。

方法

使用结构方程模型来检查情绪，PTSD和MDD结构在200名患有PTSD的个体中的作用。

结果

ER过程完全介导了NA和PTSD（β= .40，p <.001）和MDD（β= .48，p <.001）与NMR期望值和PTSD（β= -.31，p <。 001）和MDD（β= -.37，p <.001）。

结论

NA和NMR预期几乎完全通过ER过程对PTSD和MDD产生影响。ER似乎是一种转诊过程，部分解释了PTSD与MDD的同时发生。共存模型可以通过纳入ER流程以告知诊断分类和标准而受益，并通过专门针对ER流程来改善临床干预。
