Introduction to the Special Issue: Toward a Lifespan Prevention Science - A Focus on Middle and Late Adulthood.

The interdisciplinary field of prevention science was founded on the premise of a lifespan developmental model. Prevention scientists have developed a strong set of tools and intervention technologies for understanding and potentially modifying risk and protective factors through early adulthood. However, there is a demographic imperative to apply prevention science principles to health issues in middle and late adulthood. The articles in this special issue utilize a variety of methods to investigate important scientific questions about how theories, methodologies, and interventions applied in the science of prevention can be usefully integrated into the study of health and wellness in middle and late adulthood. More specifically, contributions (1) highlight current empirical research that draws on lifespan developmental science to address the unique prevention and intervention needs in middle and late adulthood, (2) illustrate the opportunities and challenges of a lifespan approach to prevention science with special attention to middle and late adulthood, and (3) identify additional areas that prevention science can contribute to advancements in middle and late adulthood. These articles provide a glimpse into the challenges and opportunities at the intersection of prevention science and gerontology. As a field, we have much room to grow in leveraging innovative tools, approaches, and efforts to best support older adults' physical, mental, and social health, particularly for diverse and under-served populations.
