OBJECTIVE: Understanding the trajectory of posttraumatic stress disorder (PTSD) in disaster victims remains a critical area of study. This study aimed to classify disaster victims into distinct PTSD trajectory groups and identify the risk and protective factors associated with each group.
METHOD: The study analyzed panel data from 3,288 disaster victims in South Korea, collected over 4 years (2016-2019). Latent class growth analysis was employed to classify PTSD trajectories based on four time-point measurements. Multinomial logistic regression was used to examine potential predictors, focusing on individual- and community-level factors.
RESULTS: Four distinct PTSD trajectory groups were identified: mild-fluctuating with latent escalation (60%), stable low with gradual relief (20%), chronic high with mild decline (15%), and early high with rapid recovery (5%). Significant predictors included income, resilience, depression, pretrauma history, and community resilience.
CONCLUSIONS: This study highlights diverse PTSD trajectories and their associated risk and protective factors. Identifying these trajectories provides critical insights for designing tailored interventions to support disaster victims' mental health.
