Dynamics in post-traumatic and depressive symptoms. Boxplots describing posttraumatic and depressive symptom over the three time points of assessment, accounting for prior to, during, and long-time following military service, respectively. A) Unconditional growth models of posttraumatic symptom levels revealed a significant effect of time (χ2(2) = 63.63, p < .001), driven by an increase in symptoms from prior to during military service and to following discharge (IRRPDS(tp2-tp1) = 2.73, Z = 7.57, p < .001; IRRPDS(tp3-tp1) = 2.18, Z = 4.95, p < .001). B) Unconditional growth models of depressive symptoms levels revealed a significant effect of time (χ2(2) = 6.69, p = .03), driven by a trend towards increase in symptoms from prior to during military service and a significant increase from prior to following discharge (IRRBDI(tp2-tp1) = 1.26, Z = 1.88, p = .060; IRRBDI(tp3-tp1) = 1.43, Z = 2.54, p = .010). Critically, for both posttraumatic and depressive symptoms, mean levels remained well below clinical threshold throughout all three time points, with majority of participants exhibiting none-to-mild symptoms. A single participant exhibited severe posttraumatic and depressive symptoms long-time following discharge and was excluded from analysis as an outlier (marked in red dot). Levels of severity norms are labeled in gray, based on (Foa, 1995) and (Beck et al., 1988) respectively.
