Objective Scalable clinician training in evidence-based trauma treatments is important to increase the use and impact of these treatments in different countries. The aim of the current pilot investigation was to understand the attitudes of mental health care providers in Chile toward narrative exposure therapy (NET), an evidence-based treatment (EBT) for traumatic distress. Method This study used a mixed-methods design and gathered demographic and questionnaire data as well as data from semi-structured qualitative interviews. A total of 31 clinicians completed the Evidence-Based Practice Attitude Scale (EBPAS) following a webinar on NET, and among those participants 10 completed semi-structured interviews. Results Findings from this study suggest mental healthcare workers reported overall satisfaction from the NET training and knowledge gained from the training. Both qualitative and quantitative findings indicated broadening understanding of trauma treatments as well as additional training and supervision are necessary in the process of learning to implement an EBT such as NET. Conclusions A web-based training in NET may be a feasible method for introducing a trauma-focused EBT; however, additional training and supervision are necessary in follow-up trainings.
