Issues of aging and adherence to health interventions.
Additional Document Info
This review article describes several processes and considerations that are important to adherence in aging research and potential strategies that could be used to facilitate adherence among older adults. In many large aging trials participants are purposefully selected to reduce the risk of suboptimal adherence and retention. This selection often involves screening out those with barriers such as transportation needs, sensory deficits, functional dependence, major diseases limiting life expectancy, or apparent psychological distress. However, trends toward extending interventions to the general population of older adults require specific knowledge about the circumstances and processes that support adherence among older adults or the conditions that make them vulnerable to adherence problems. Addressing the diversity of needs, expectations, and capabilities of older adults that promote adherence is a key consideration in aging research. Control Clin Trials 2000;21:171S-183S
