  1. One-way ANOVA with post hoc Tukey HSD test. M = Mean; SD = Standard Deviation. The α-level was adjusted with Bonferroni correction; α = 0.004 for the individual personality traits and α = 0.017 for the personality factors. Unless otherwise stated, p-values for comparisons with the comparison group are reported
  2. a p < 0.001 in comparison with women who developed PTSD/PTSS
  3. a p < 0.001 in comparison with women who recovered from PTSD/PTSS
