Objective: Prior research has identified different PTSD symptom (PTSS)trajectories over months and years posttrauma that warrant different levels of clinical attention. Earlier identification of at-risk trauma victims can facilitate efficient and appropriate intervention efforts. Method: Using latent class growth analysis, we examined daily PTSS trajectories beginning 6 weeks postinjury in 68 injury victims. Resulting classes were compared on key characteristics at 6 and 21 weeks postinjury. Results: Three trajectories were identified: a nonreactive class (67.8%) with low initial symptom levels that remained low, a moderate-stable class (27.9%) with elevated symptom levels that remained constant, and a severe-increasing class (4.4%) with high symptom levels that increased. Conclusions: High-risk injury victims can be identified by their daily PTSS, allowing for early identification of those at risk for elevated distress and in greater need for intervention.
