The current study examined whether various types of rumination are distinguishable and the effects of personal growth initiative (PGI) on posttraumatic growth, posttraumatic stress, and depression through adaptive and maladaptive rumination.
Sample included 292 college students who experienced a potentially traumatic event (PTE).
Intrusive and deliberative rumination were found to be distinct factors. However, brooding and reflection, thought to be separate aspects of depression, were a single factor. PGI was positively associated with growth and negatively associated with depression for both genders, and a negative relationship was found between PGI and posttraumatic stress among women. Indirect effects of PGI were found on posttraumatic stress and growth through different forms of rumination. These relations did not change after including the covariates (i.e., time since the trauma, direct exposure, and intentional harm).
The study provides new insight integrating rumination from the depression literature in the context of trauma and a potential benefit in applying PGI in alleviating pathology after a PTE and facilitating growth.
本研究探讨了不同类型的反刍思维是否可区分，以及个人成长主动性（PGI）通过适应性和适应不良性反刍思维对创伤后成长、创伤后应激及抑郁的影响。
样本包括292名经历过潜在创伤性事件（PTE）的大学生。
侵入性反刍思维和深思性反刍思维被发现是不同的因素。然而，被认为是抑郁不同方面的沉思和反思却是单一因素。PGI与两性的成长呈正相关，与抑郁呈负相关，且在女性中PGI与创伤后应激呈负相关。通过不同形式的反刍思维发现了PGI对创伤后应激和成长的间接影响。纳入协变量（即创伤发生后的时间、直接暴露和故意伤害）后，这些关系并未改变。
本研究为在创伤背景下整合抑郁文献中的反刍思维提供了新见解，并为应用PGI减轻PTE后的病理症状及促进成长提供了潜在益处。
