OTHER PROJECT INFORMATION – Summary/Abstract Behavioral Intervention Development Core The BID core is the scientific focus of the Center. Through statistically-powered clinical trials, the core evaluates mechanisms of behavior change that can drive health-related actions, and tests interventions that nudge behaviors in ways that are likely to improve health outcomes. Roughly two clinical trials will be initiated each year, including continuations and extensions of ongoing Center trials. Among the categories of health-related behavior we plan to study are interventions to increase healthy behaviors, decrease unhealthy behaviors, and improve provider decision-making. Our mission is to move promising interventions through the NIH Stage Model, from basic science (Stage 0) and initial intervention development and testing (Stage 1), through efficacy (Stage 2-3) and effectiveness (Stage 4) testing, and eventually on to dissemination and implementation research (Stage 5). A unique feature of our BID core is infrastructure to partner with researchers at Geisinger Clinic, a non-profit health care network and insurer with a rich history of innovative delivery reforms and experimental research.
