Middle school students in Wenchuan County (N = 354) were assessed 4.5 years after the Wenchuan earthquake to examine the effects of challenges to core beliefs, intrusive rumination, and deliberate rumination on posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG). The results indicated that intrusive rumination partly mediated the relationship between challenges to core beliefs and PTSD, whereas deliberate rumination partly mediated both the relationship between challenges to core beliefs and PTG, as well as the relationship between intrusive rumination and PTG. These findings suggest that challenges to core beliefs had a direct positive impact on both PTSD and PTG. Moreover, such challenges predicted PTSD through intrusive rumination and predicted PTG through deliberate rumination. Furthermore, intrusive rumination might cue individuals to engage in a more purposive deliberate rumination process. These results indicate that PTSD and PTG are influenced by different mechanisms and that PTSD and PTG represent 2 separate dimensions of experience following adversity.
4.5 年后，对汶川地震后的汶川县（N=354）中学生进行评估，以检验核心信念挑战、侵入性反刍和刻意反刍对创伤后应激障碍（PTSD）和创伤后成长（PTG）的影响。结果表明，侵入性反刍部分中介了核心信念挑战与 PTSD 之间的关系，而刻意反刍部分中介了核心信念挑战与 PTG 之间的关系，以及侵入性反刍与 PTG 之间的关系。这些发现表明，核心信念的挑战对 PTSD 和 PTG 都有直接的积极影响。此外，这种挑战通过侵入性反刍预测 PTSD，通过刻意反刍预测 PTG。此外，侵入性反刍可能会促使个体进行更有目的的刻意反刍过程。这些结果表明，PTSD 和 PTG 受到不同机制的影响，并且 PTSD 和 PTG 代表逆境后体验的两个独立维度。
