The 125 participants had a mean (SD) age of 15.96 (1.97) years. Overall sample size for primary analyses included 80 adolescents in the METRA group and 45 adolescents in TAU. Following the intention-to-treat principle, generalized estimating equations found that the METRA group had a 17.64-point decrease (95% CI, −20.38 to −14.91 points) in PTSD symptoms and a 6.73-point decrease (95% CI, −8.50 to −4.95 points) in depression symptoms, while the TAU group had a 3.34-point decrease (95% CI, −6.05 to −0.62 points) in PTSD symptoms and a 0.66-point increase (95% CI, −0.70 to 2.01 points) in depression symptoms, with the group × time interactions being significant (all
