Due to the limited supply of mental health services for Afro-Colombian victims of violence, a Common Elements Treatment Approach (CETA) intervention has been implemented in the Colombian Pacific. Given the importance of improvement in mental health interventions for this population, it is necessary to characterize this process. This article seeks to describe the implementation of CETA for Afro-Colombian victims of violence in Buenaventura and Quibdó, Colombia through case studieswith individual in-depth interviews with Lay Psychosocial Community Workers (LPCW), supervisors, and coordinators responsible for implementing CETA. From this six core categories were obtained: 1. Effect of armed conflict and poverty 2. Trauma severity 3. Perceived changes with CETA 4. Characteristics and LPCW's performance 5. Afro-Colombian culturalapproach and 6. Strategies to promote users' well-being.Colombian Pacific's scenario implies several factors, such as the active armed conflict, economic crisis, and lack of mental health care resources, affecting the implementation process and the intervention effects. This implies the need to establish and strengthen partnerships between institutions in order to administer necessary mental health care for victims of violence in the Colombian Pacific.
