Structural model of cross-lagged relationship between anxiety sensitivity (AS) and PTSD symptom severity (PTSD), at baseline (0), 6 months (6), and 12 months (12). (The measurement model is not shown). Standardized parameter estimates are shown first, followed by unstandardized estimates in parentheses. Paths are statistically significant at p < 0.001, except paths from AS to subsequent PTSD symptoms, where p = 0.004, and from PTSD at baseline to PTSD at 12 months, where p = 0.003.
