Each branch of service within the Department of Defense (DoD) relies on interdisciplinary Human Performance Team (HPT) assets to meet force readiness goals. HPTs are composed of professionals in widely varying fields, including but not limited to clinical psychologists, dieticians, athletic trainers, chaplains, performance psychology practitioners, and medical providers. HPTs provide services across the entire continuum of care: From recovery and restoration, to prevention, to intervention, and performance optimization. To enable truly holistic and integrated support required for addressing complex health and performance issues for our warfighters (e.g. GAO-22-104486), HPTs must be provided with additional professional development opportunities to develop critical competencies to reduce silos and enable coordinated support. The present study closed the knowledge gap required to develop targeted interventions for enhancing interprofessional and multidisciplinary collaboration among HPTs employed by Human Performance Optimization (HPO) and Total Force Fitness (TFF) programs across the DoD. The study methodology was qualitative and exploratory, utilizing focus groups via an internet-based video call. Focus groups were conducted with a convenience sample of HPT professionals, assigned to multiple DoD locations. Content analyses revealed themes related to improving processes for HPT members integrating on to a team, understanding collaborative and referral processes within the team, cultural competencies required to work successfully with a military population, and clarifying the qualities of who is providing services and how they are being provided. All of these highlighted competencies are critical for maximizing the impact of these services and concrete recommendations for HPO/TFF programs will be provided.
