Additionally, we aimed investigate extent which these are moderated by combat-stress severity, what findings replicated second, separate corpsmen 938) identical measures deployment within 3 return. Method: employed latent variable path models examine pre-deployment post-deployment re-experiencing symptoms. Initial cross-lagged were conducted discovery replication samples validate hypothesized predictive relationships. Follow up moderation then include effect severity Results: supported significant future symptoms all time points. showed small moderator though main remained significant. was not sample. Conclusions: results this support risk factor for Interventions normalizing may be important preventive PTSD.
