Despite extensive research on mindfulness, there is a dearth of studies exploring its impact on post-traumatic stress disorder (PTSD) through the intermediaries of psychological resilience and perceived stress. In response to a violent campus event, this article investigates the association between mindfulness levels among college students and the presence of PTSD using a sequential mediation model.
We recruited 324 participants from a university following a violent event and collected 314 valid data. All the participants signed the informed consent and completed self-report measures of mindfulness (MASS), stress perception (PSS), resilience (CD-RISC) and PTSD (PCL-5). The SPSS PROCESS model 6 was utilized to investigate the chain mediation model.
(1) There exists a notable positive correlation between mindfulness and resilience (r = 0.45, p < 0.01), while a significant negative correlation is observed between mindfulness and stress perception (r = -.55, p < 0.01), as well as PTSD (r = -.51, p < 0.01). (2) Resilience (effect = -0.1109) and stress perception (effect = -0.1359) play a mediating role between mindfulness and PTSD, respectively. (3) Stress perception is predicted by resilience (β = -0.62, t = -15.96, p < 0.001). (4) Stress perception and resilience play a chain mediating role between mindfulness and PTSD (effect = -0.1301).
In the aftermath of the campus violence incident, PTSD experienced by college students can be affected by mindfulness through a chain mediating effect of stress perception and resilience.
尽管对正念进行了广泛研究，但通过心理韧性和感知压力这两个中介来探究其对创伤后应激障碍（PTSD）影响的研究却很匮乏。针对一起校园暴力事件，本文采用序列中介模型研究大学生正念水平与PTSD存在情况之间的关联。
我们在一次暴力事件后从一所大学招募了324名参与者，并收集到314份有效数据。所有参与者均签署了知情同意书，并完成了正念（MASS）、压力感知（PSS）、韧性（CD-RISC）和PTSD（PCL-5）的自我报告测量。使用SPSS PROCESS模型6来研究链式中介模型。
（1）正念与韧性之间存在显著正相关（r = 0.45，p < 0.01），而正念与压力感知（r = -0.55，p < 0.01）以及PTSD（r = -0.51，p < 0.01）之间存在显著负相关。（2）韧性（效应 = -0.1109）和压力感知（效应 = -0.1359）分别在正念与PTSD之间起中介作用。（3）韧性可预测压力感知（β = -0.62，t = -15.96，p < 0.001）。（4）压力感知和韧性在正念与PTSD之间起链式中介作用（效应 = -0.1301）。
在校园暴力事件发生后，大学生经历的PTSD会通过压力感知和韧性的链式中介效应受到正念的影响。
