This symposium presents cutting-edge investigations exploring various dimensions of the concept of engagement in later life. The first two presentations focus on results from the EngAGE Study, which was an Ecological Momentary Assessment (EMA) study that examined the real-time experiences of contemporary older adults involved in paid work, volunteering, and caregiving. The first of these focuses on the feasibility of using iPad technology to collect EMA data among older adults, while the second focuses on testing a mediation model of daily engagement and its effects on health and well-being. The third presentation reports on findings of a randomized controlled trial of the Engaged4Life program, which was an intervention focused on increasing meaningful activity engagement and physical activity among community dwelling older adults. The fourth presentation brings together research across diverse disciplines to propose a conceptual framework and research agenda for the study of engagement in paid and unpaid work in later life. A discussant will comment on how these various papers expand the scope of aging research and will relate this discussion to the American Academy of Social Work & Social Welfare’s Grand Challenge on Advancing Long and Productive Lives.
