Some people experience cumulative advantages or disadvantages at birth and during their lifespan that determine future life course outcomes. Health disparities and systemic inequity can define a negative trajectory for some minority and underserved communities. Without intervention, such inequity can spiral and eventually affect more and more areas of an older person's life, much like cumulative disadvantages. This research proposes that older adults can improve their situation through targeted support factors that systematically improve lifespan areas. Eventually, more adults can experience the cumulative advantage effect as life progresses. The dissertation consists of a systematic literature review to evaluate literature that isolates degree-level education as a predictor of successful retirement transition planning. This foundational information is used as a basis for identifying constructs in two follow-on studies of the longitudinal National Health and Aging Trends Study (NHATS) Wave 9 public dataset. We explore factors supporting readiness for retirement and retirement transition in later life using data of older adults aged 65+. Multiple regression, exploratory factor analysis, and partial least squares structural equation modeling (PLS-SEM) are used to gain a multi-angle view. The results showed that degree-level education influences higher salaries, improved healthcare access, and financial literacy. In addition, old age has …

This study will extend the current body of knowledge about how accessible and affordable information communication technologies (ICT; smartphones, tablets, and computers) can foster social interaction and reduce social isolation and loneliness in older adults aged 55 plus. The first study is a systematic literature review of existing studies on ICT and the willingness of older adults to use technology. The second study is quantitative research that investigates the trust and reasoning of older adults using ICT, like smartphones, tablets, and computers that foster social interaction and the level of technological ownership. The second study is conducted using research data through surveys conducted by Pew Research Center on behalf of Princeton University. Finally, the third study explores the level of ownership of technology and methods to reduce social isolation using ICT. The effectiveness of smartphones, tablets, and computers that foster social interaction were reviewed to create a sense of community to reduce social isolation.

Loss is an inevitable part of life. The actual process of grieving is unique and can be hard to quantify. Grief interventions can address the relationship quality and attachment status between the griever and the deceased and how memories are interpreted and carried into the present and future. This three-essay dissertation explores variations of loss and the factors that contribute to a resilient recovery.
