Data are frequencies and mean (SD). Univariate results (Chi-square tests and ANOVAs) are also reported.

^aRM vs. SGP: ${\chi }_{\mathit{\text{1}}}^{\mathit{\text{2}}}$ = 6.465, p = 0.011; RM vs. CTR: ${\chi }_{\mathit{\text{1}}}^{\mathit{\text{2}}}$ = 1.758, p = 0.185; SGP vs. CTR: ${\chi }_{\mathit{\text{1}}}^{\mathit{\text{2}}}$ = 1.616, p = 0.204.

^bDue to the absence of the variability of SGP group, a t-test for independent sample was conducted to compare RM vs. CTR

^cAll these 10 patients had a current sub-syndromal PTSD (intrusive experiences of trauma during the last month without reaching a Full MINI-Plus PTSD diagnosis).
