This Project Grant award of $3,024,846.00 from the Defense Health Agency's Military Medical Research and Development program (CFDA 12.420) is funding a cluster randomized controlled trial of the X-CORE sexual assault prevention intervention for active-duty Airmen. The project will be conducted by the University of Texas Health Science Center at Houston (UTHealth) from September 1, 2023 through August 31, 2027. The goal is to evaluate the effectiveness of this multilevel sexual assault prevention program for the U.S. Air Force population. UTHealth has significant expertise in federal research grant programs, frequently serving as both a prime recipient and sub-awardee on projects supported by agencies such as the NIH, CDC, and VA. This award leverages UTHealth's biomedical and public health research capabilities to address an important military health need.
