The aim of this interventional research is to evaluate the effectiveness of CFTSI in reducing post-traumatic symptoms measured using the CPC, child version, at the end of CFTSI treatment in children and adolescents aged between 7 and 17 years, exposed to an ET in the last 3 months. The main question(s) it aims to answer \[is/are\]:
* CFTSI reduces posttraumatic Child Posttraumatic Stress Checklist (CPC) scores in children exposed to ET, both immediatly after completion of the CFTSI and at 3 months after completion.
* CFTSI reduces post-traumatic scores in parents on the PTSD Checklist for DSM5 (PCL), both immediatly after completion of the CFTSI and at 3 months after completion.
* researchers will compare the reduction in post-traumatic symptoms between participants receiving CFTSI and those receiving non-specific child-centred psychological support. Symptoms will be assessed using the PCL in parents and the CPC in children and adolescents, immediately after completion of the program and again at 3 months after completion.
The participants will be randomised into two groups, one that will undergo CFTSI and one that will undergo supportive psychological therapy. Each participant will receive one session per week over five weeks, and possibly 1 to 3 additional sessions if necessary over a further three weeks, and will then be reviewed three months later.
