Posttraumatic growth (PTG) is viewed as a positive psychological change resulting from a struggle with trauma. A number of trauma-related factors have been proven effective in predicting PTG; however, the effects of pretrauma psychological factors on PTG have not been adequately evaluated (e.g., using a prospective design). This prospective study examined the effects of pretrauma psychological factors (e.g., coping styles, prior trauma) on PTG. In total, 810 Taiwanese undergraduate students were recruited for a baseline survey (Time 1), among whom 592 completed a survey 2 months later (Time 2). Data from 110 participants who had experienced trauma between Time1 and Time 2 were used for analysis. Among the pretrauma factors examined at baseline, only rumination and distractive style were positively correlated with PTG. The posttrauma factors based on Calhoun and Tedeschi's model (i.e., core belief challenge, deliberate rumination, and social support) were also positively correlated with PTG. A hierarchical regression analysis showed that pretrauma coping styles had an incremental effect on PTG beyond posttrauma predictors. Deliberate rumination signifciantly mediated the relationship between pretrauma rumination and PTG. These findings highlight the role of pretrauma psychological factors in PTG and present further support for Calhoun and Tedeschi's model of PTG.
创伤后成长（PTG）被视为一种积极的心理变化，源于与创伤的抗争。许多与创伤相关的因素已被证明可以有效地预测 PTG；然而，创伤前心理因素对 PTG 的影响尚未得到充分评估（例如，采用前瞻性设计）。本前瞻性研究探讨了创伤前心理因素（例如应对方式、先前的创伤）对 PTG 的影响。共有 810 名台湾大学生参加了基线调查（第 1 次时间点），其中 592 人在 2 个月后完成了调查（第 2 次时间点）。使用了 110 名在第 1 次和第 2 次时间点之间经历过创伤的参与者的数据进行分析。在基线检查的创伤前因素中，只有沉思和分散注意力的方式与 PTG 呈正相关。基于 Calhoun 和 Tedeschi 模型的创伤后因素（即核心信念挑战、刻意沉思和社会支持）也与 PTG 呈正相关。层次回归分析表明，创伤前应对方式对 PTG 的影响超过了创伤后预测因素。刻意沉思显著中介了创伤前沉思与 PTG 之间的关系。这些发现强调了创伤前心理因素在 PTG 中的作用，并进一步支持了 Calhoun 和 Tedeschi 的 PTG 模型。
