Evaluación del efecto de intervenciones grupales basadas en TF-CBT e IPT en el funcionamiento psicosocial de adolescentes expuestos a violencia interpersonal en Chile: Un protocolo de ensayo clínico piloto

This paper describes the protocol developed in Chile to evaluate interventions with adolescents exposed to interpersonal violence and follows CONSORT guidelines (Shulz et al., 2010). The objective is to evaluate the effectiveness of two group intervention models (Trauma Focused Cognitive Behavioral Therapy and Interpersonal Therapy) in stabilizing the psychosocial functioning of adolescent participants. Methods/Design. This is a randomised-controlled trial with three groups: two intervention groups (TF-CBT and IPT) and an active control group (art therapy). The participants will be 84 adolescents between 13 to 17 years old who are on the waiting list for treatment in specialist trauma services. Participants will be assigned to one of three groups and will participate in 12 group therapy sessions. Participants' progress in post-traumatic stress symptomatology, depressive symptomatology, self-regulation problems and interpersonal problems will be evaluated. Measures will be administered before the start of the intervention, in sessions six, seven, twelve and two months after the end of the intervention. Adherence to the intervention and its acceptability by the participants will also be evaluated. Discussion. This study seeks to contribute to the development of scalable evidence-based interventions in the Chilean context to improve access to specialist intervention.
