Longitudinal patterns of PTSD symptom classes among US National Guard service members during reintegration

ConclusionsThe four latent PTSD classes were distinguished primarily by severity; however, the mild symptom class was characterized by higher levels of hyperarousal than other symptoms. Although the absolute number of individuals within classes remained fairly constant between 6 and 12 months, there was movement between severity classes. Most NG service members without symptoms continued to do well during the first year, with only an estimated  7% moving to the moderate or severe class.
