Studies examining the association between personal growth initiative (PGI) and post‐traumatic stress symptoms (PTSS) have often utilized cross‐sectional research designs, and as a result, the changes in the levels of PGI and its association with the trajectory of PTSS remain unclear. The current study aimed to (1) explore the different trajectories in both PGI and PTSS and (2) examine the associations of the identified trajectories between PGI and PTSS among individuals. The final sample were 419 adults who were physically residing in the area when Hurricane Harvey made landfall on 26 August 2017. The initial data collection occurred approximately 16 months after the Hurricane, and participants were asked to participate again after 1‐ and 3‐month later. A result from the latent growth mixture modeling revealed that for PGI, the 4‐class model was the best‐fitting model, and for PTSS, the 3‐class model was the best‐fitting model. When examining the association between the trajectories of PGI and PSS, individuals classified to higher PGI subgroups were more likely to be associated with the Recovery PTSS subgroup. The current study suggests that disaster survivors with higher PGI were more likely to recover from PTSS, raising an importance of incorporating PGI to alleviate future PTSS.

飓风哈维后个人成长主动性轨迹与创伤后压力之间的关联：潜在增长混合建模方法

检查个人成长主动性 (PGI) 与创伤后压力症状 (PTSS) 之间关联的研究经常采用横断面研究设计，因此，PGI 水平的变化及其与 PTSS 轨迹的关联仍然存在不清楚。目前的研究旨在 (1) 探索 PGI 和 PTSS 中的不同轨迹，以及 (2) 检查个体之间 PGI 和 PTSS 之间已识别轨迹的关联。最终样本是 2017 年 8 月 26 日飓风哈维登陆时实际居住在该地区的 419 名成年人。 初始数据收集发生在飓风后大约 16 个月，参与者被要求在 1 个月和 3 个月后再次参与. 潜在生长混合物模型的结果表明，对于 PGI，4-class 模型是最佳拟合模型，对于 PTSS，3-class 模型是最佳拟合模型。在检查 PGI 和 PSS 轨迹之间的关联时，归类到较高 PGI 亚组的个体更有可能与恢复 PTSS 亚组相关。目前的研究表明，具有较高 PGI 的灾难幸存者更有可能从 PTSS 中恢复过来，这提高了纳入 PGI 以缓解未来 PTSS 的重要性。
