High rates of under-assessed trauma and psychiatric disorders, particularly posttraumatic stress disorder (PTSD) have been reported among Hispanic immigrants, especially as related to immigration trauma. Multiple studies have shown group cognitive processing therapy (CPT) to be an effective evidence-based practice (EBP) for treatment of PTSD across a number of clinical populations. To date, however, no studies have examined important competency and practice issues in linguistic, cultural, and ethical areas that group CPT providers should consider when delivering group CPT to Hispanic immigrants. This paper aims to outline these and provide future directions for research.
