  • by CAPS at 6 months (42.9 vs. 56.7, p<0.01) and 12 months (38.6 vs. 47.2, p<0.05) after injury
  • by greater decrease in CAPS over 12 months following injury (group by time interaction, p<0.01)
  • by PCL-C at 6 months (40.6 vs. 49.9, p<0.01), 9 months (40.2 vs. 45.5, p<0.01) and 12 months (37.4 vs. 42.5, p<0.05) after injury)
