This study focuses on the mediating effects of problem-focused coping and happiness-increasing strategies on the relationship between psychological hardiness and posttraumatic growth in a sample of individuals (N = 1069) exposed to various traumatic events. The data in the study were analysed with the structural equation model. The nested models strategy and bootstrapping were used to test the mediation effects in the model. Based on the results of the analysis, it was concluded that the relationship between psychological hardiness and posttraumatic growth is mediated by happiness-increasing strategies and problem-focused coping. It was further observed that problem-focused coping has a mediating effect on the relationship between happiness-increasing strategies and posttraumatic growth and those happiness-increasing strategies have a mediating effect on the relationship between psychological hardiness and problem-focused coping. Thus, problem-solving and emotion-regulating skills may have an effect on the relationship between psychological hardiness and posttraumatic growth.

本研究重点关注以问题为中心的应对策略和增加幸福感的策略对个体样本（N = 1069) 暴露于各种创伤事件。研究数据采用结构方程模型进行分析。嵌套模型策略和引导用于测试模型中的中介效应。根据分析结果，得​​出结论，心理韧性与创伤后成长之间的关系是由增加幸福感的策略和以问题为中心的应对方式介导的。进一步观察到，以问题为中心的应对在增加幸福感的策略与创伤后成长之间的关系中具有中介作用，而这些增加幸福感的策略在心理韧性与以问题为中心的应对之间的关​​系中具有中介作用。因此，
