The objective of the DECISION-MAP project is to systematically identify, organize, and visualize evidence addressing mental health and addictions interventions for people with acquired brain injury. Our mission is to provide a dynamic, interactive, and accessible platform for knowledge users to locate and engage with up-to-date research findings that can be used to aid in evidence-based decisions, such as treatment planning, program development, research agenda-setting, or resource allocation. DECISION–MAP is a hub of empirical evidence that can be accessed and evaluated by those who need it most, including people with lived experience, service providers and health care professionals, researchers, clinicians, and policy makers.
