This research investigates the use of trauma-focused cognitive behavioral therapy for complex presentations (TF-CBT-CP) delivered through videoconference to adults diagnosed with post-traumatic stress disorder (PTSD) or complex PTSD (CPTSD). The study aims to evaluate how feasible and acceptable this videoconference therapy is for patients treated at community mental health services and hospitals in the Maule Region of Chile. The study also explores participant satisfaction, reasons for refusal or dropout, and the therapy's impact on PTSD and CPTSD symptoms, depression, anxiety, emotional regulation, and psychological well-being. Participants will receive TF-CBT-CP therapy consisting of 16 weekly sessions lasting 60 minutes each, delivered via videoconference. The treatment includes clinical assessments, psychoeducation, coping strategy development, behavioral activation, emotional regulation and interpersonal skills training, exposure to traumatic memories, cognitive interventions, and relapse prevention. Therapy will be provided by trained clinical psychologists with weekly supervision to ensure fidelity to the protocol. Sessions and evaluations will take place in clinical settings equipped with necessary technology to support videoconferencing. Participants will be involved in initial assessments, treatment sessions, and follow-up evaluations at 16 and 20 weeks after starting treatment. Assessments include interviews and questionnaires measuring PTSD and CPTSD symptoms, depression, anxiety, suicidal ideation, alcohol use, emotional regulation, and functioning. Participant satisfaction and acceptability will be evaluated through questionnaires and telephone interviews. The study will monitor feasibility indicators such as eligibility, recruitment, participation, retention, dropout, and completion rates throughout the study period.
