Objective: Several gaps remain in the understanding of the onset, dynamic transitions, and associated risk factors of adverse posttraumatic neuropsychiatric sequelae (APNS) in the acute post-trauma window. Based on serial assessments of symptoms from a large cohort study, we identified homogeneous statuses across multiple APNS symptom domains and investigated the dynamic transitions among these statuses during the first 2 months after trauma exposure. Furthermore, we studied how symptom onset and transitions are affected by equity-relevant characteristics.
Methods: The analysis was based on 2557 participants enrolled in the Advancing Understanding of RecOvery afteR traumA (AURORA). APNS symptoms comprised pain, depression, sleep discontinuity, nightmares, avoidance, re-experience, anxiety, hyperarousal, somatic symptoms, and mental fatigue. We identified the homogeneous status of APNS symptoms at baseline, 1 month, and 2 months, and explored transition probabilities among these statuses using latent transition analysis. Equity-relevant characteristics included gender, race, education, family income, childhood trauma, and area deprivation.
Results: Three homogeneous statuses-low-, moderate-, and severe-symptom-were identified. While the majority of trauma survivors with severe- or moderate-symptom status maintained the same status over time, some transitioned to a less severe symptom status, particularly within the first month. Specifically, females, non-whites, and those with higher childhood trauma were associated with a decreased likelihood of transitioning to a less severe symptom status. From one to 2 months, lower income was associated with a decreased likelihood of transitioning from moderate-to low-symptom status.
Conclusions: The findings can inform early intervention strategies for APNS, potentially reducing health disparities among trauma survivors.
