DoD personnel who pose a threat or experience personal problems may show early warning signs but supervisors do not always recognize indicators or report their concerns through proper channels. A literature review and subject matter expert (SME) interviews collected information about barriers to reporting, strategies for overcoming these barriers, and tools to assist with the reporting process. This study also evaluated the utility and feasibility of using the United Kingdom Centre for Protection of National Infrastructure Employee Assessment Tools to supplement automated continuous evaluation and to provide supervisors an early intervention channel for at-risk employees. Literature review findings suggest that a comprehensive approach to prevention and mitigation of misconduct may increase the likelihood of reporting, and vice versa. Increased reporting may be achieved by providing a clear, easily used, and trusted reporting system, along with a positive organizational culture that makes felt responsibility to report stronger than the psychosocial impediments. SMEs interviewed for this study recommended clarifying reporting policy, providing additional scenario-based training, and improving relationships between supervisors and security managers. Some SMEs also emphasized the importance of holding personnel accountable for reporting security concerns. They suggested that accountability is currently inadequate, which may contribute to underreporting. The researchers concluded that the Employee Assessment Tools are not appropriate for the entire DoD cleared population, but are an excellent example of a reporting tool for individuals in high-risk positions.
