Task-shifting of prolonged exposure for primary care (PE-PC) for PTSD in a semirural setting in South Africa: A pilot implementation study.

Implementation science (IS) has received increased attention as it provides a means to bridge the know-do gap to implement evidence-based interventions in real-world settings. Against this backdrop, posttraumatic stress disorder (PTSD) is a global mental health concern (Koenen et al., 2017), especially in low- and middle-income countries characterized by limited trained health professionals, infrastructure, and limited access to evidence-based mental health care (Chen et al., 2017). Over the last 3 decades, effective trauma-focused psychotherapies (TFPs) for PTSD have been developed (Hamblen et al., 2019). Prolonged exposure therapy (PE) is a first-line TFP for PTSD (Hamblen et al., 2019), yet the dissemination and implementation of PE have been limited to specialty care settings in developed or industrialized countries (Booysen & Kagee, 2020). Implementation science provides an opportunity for disseminating and implementing TFPs like PE in low- and middle-income countries. This article describes mixed-method data from a pilot implementation study of an abbreviated version of PE, known as prolonged exposure for primary care (S. A. M. Rauch, Kim, et al., 2023), in a semirural city in the Eastern Cape of South Africa. Importantly, prolonged exposure for primary care shows a significant reduction in PTSD when provided by lay counselors and good feasibility and acceptability. In addition, we reflect on the barriers and facilitators related to implementation research within a low-resourced community, namely, (a) training lay counselors, (b) cultural diversity, and (c) mental health literacy. Mental health literacy is proposed as an essential component to consider in implementation science, especially in low-resourced communities.
