Recruiting older adults to participate as subjects in research studies is critical, particularly in specific populations. A relatively high proportion of older adults agree to participate in population-based research studies, and their participation tends to be higher in those with older age (Sonnega et al. 2014; Wong et al. 2017a). Moreover, retention of older adults in research studies is relatively favorable, as most researchers find that, once recruited, older adults are less likely than younger persons to drop out of the research project (Orozco et al. 2018). In longitudinal studies of aging research, the goal is to follow older adults prospectively as they age. Once the study subjects are recruited, considerable efforts are made to minimize attrition or losses over time because, in population-based research, the losses may jeopardize the initial sample’s representation of the...
