This study is a randomized clinical trial at psychiatric rehabilitation services of the Public Network of Care for people with serious mental disorders. We hypothesize that participants receiving the intervention, in comparison with controls, will show a reduction in general, PTSD and psychotic symptomatology, an improvement in levels of functioning and well-being, a greater ability to regulate emotions with more help-seeking behaviours.
Given the complexity of both psychosis and PTSD and the reluctance of professionals to treat it, we plan to develop a precise comprehensive protocol. In order to address all issues associated with both psychosis and comorbid PTSD, the protocol will be developed following the three stages of recovery from trauma: first, focusing on establishing the therapeutic alliance and safety; second, focusing on recounting and re-processing the traumatic event; and third, focusing on reconnecting with others and with life despite the trauma experienced. The therapy will be adapted to the characteristics of people with SMD and administered in 11 90-minute individual sessions per week, combining strategically ACT, Mindfulness, EMDR as well as Positive Psychology interventions.
