Economic evaluation: An economic evaluation will be conducted alongside the randomized trial and will be performed according to the intention-to-treat principle.

We will perform both a cost-effectiveness analysis with PTSD symptoms as effect measure and a cost-utility analysis using QALYs, based on the EuroQol 5D (EQ-5D-5L). | — |
