Why are cross-sectional studies the most common type of research design in gerontology?
While many gerontological researchers would like to conduct longitudinal research, the constraints of time and money often prevent them from doing so. Cross-sectional research is much less expensive and less time consuming because it allows researchers to study people of different chronological ages at one measurement period. As a result, cross-sectional studies are the most common ones in gerontology. • At what point does a person change from “active” versus “dependent” life expectancy. How does income level impact a person’s likelihood of being categorized as being in active or dependent life expectancy? Active life expectancy is consistent with the concept of maintaining active, healthy aging. The change from active to dependent life expectancy occurs when one loses their independence or needs to rely on others for most activities of daily living. Persons with lower incomes have fewer years of active life expectancy compared to their wealthier cohorts. • Describe how old age was vie
