Purpose of Review <p>This review identified the relative frequency of use of various types of providers delivering practice elements in 130 child mass trauma interventions and compared the use of these providers across events, populations, and settings.</p> Recent Findings <p>Mental health professionals (MHPs) more frequently delivered cognitive, self-monitoring, exposure, and narrative elements than other providers while non-specialist providers (NSPs) and teachers and school personnel (TSPs) delivered support networking and social skills training more frequently. MHPs administered interventions to targeted populations more frequently, and TSPs administered interventions to universal populations more frequently. Only MHPs administered interventions at clinical facilities; NSPs delivered a majority of interventions at community sites.</p> Summary <p>Understanding the specific practice elements delivered by providers with different backgrounds and training can inform efforts to enhance the reach and impact of mass trauma services. Future publications should report greater detail about providers and their training and about specific practice elements used.</p>
