Abstract. Objective: Lack of governmental funding/infrastructure for mental health has created urgent need for effective training in evidence-based treatments for trauma in the Caribbean for under-resourced providers. Furthermore, impacts of the COVID-19 health crisis on providers’ implementation of skills in this region are currently unknown. Method: We examined impacts of a one-day training workshop for stakeholders in the Caribbean providing psychoeducation on trauma and PTSD and training in short-term interventions. Participants ( n = 46) were surveyed at preworkshop and postworkshop and at 3-month and 6-month follow-up (which coincided with the first 6 months of the COVID-19 pandemic) to assess retention of any changes in perceived knowledge about trauma/effective treatments and subsequent skill implementation. Results: Participants reported significant pre–post workshop increases in perceived knowledge (pre M = 31.61, post M = 44.63) about trauma and its effective treatments ( t[45] = −6.17, p < .001). This perceived knowledge was significantly maintained over time (3M M = 42.66, 6M M = 40.75). Furthermore, participants reported significant use of several of the strategies taught at the workshop at follow-up. Higher reported emotional distress related to the pandemic was associated with lower implementation at 6M, despite significant retention in perceived knowledge from the workshop ( B = −0.02, β = −1.55, p < .05). Conclusions: Brief trauma-focused trainings can be helpful for providers in under-resourced global settings with observable impact on implementation practices over time, but providers’ emotional distress stemming from public health crises can influence practice behaviors. Subsequent impacts on policy/budget allocations are discussed.
